Интересный аппарат. В течении 7 лет я наблюдаю за выходящими програмными
модулями реверберации и жду, когда же со студии можно будет выкинуть все
железо. К сожалению програмные аналоги Lexicon звучат гораздо хуже
бюджетного Alesis Microverb 4. Вообщем купил я прибор, который на момент
выхода стоил около $1000. Сравнивался прибор с Alesis Microverb 4, Alesis
Midiverb 4, Lexicon MPX 100. Сводилась фонограмма и на посыл-возврат
пульта ставились сравниваемые приборы. Скажу сразу — Quadraverb был лучшим,
речь идет именно о реверберации. Остальные приборы звучат впринципе
индентично друг другу, причем работу Lexicon конкретно слышно, он видимо
пытается создать свой фирменный звук, но на $4000 не дотягивает. На мой
взгляд работа прибора не должна быть заметна, и если в дешевых Alesis
можно найти такую программу (за исключением больших обьемов в медленных
песнях), то в дешевом Lexicon их нет. По этой же причине мне сильно не
понравилась обработка ZOOM, ее металлические хвосты прут из любой фанеры.
Alesis Quadraverb проявил два замечательных свойства: его работы не слышно,
просто у вокала появляется обьем, и самое главное его обьем чудесным
образом меняет частотную характеристику вокала. Появляется прозрачность,
вокал становится более читаемым. Такого у дешевых приборов я не слышал.
Могу предположить, что конверторы хотя и 16 бит но более качественные и
прибор делался как основной ревербератор студии, а не набор безумств
хорус + ленжер + дилей + ревер в различных конфигурациях. В Alesis
Quadraverb за каждый эффект отвечает отдельный блок, а тот же MIcroverb 4
в комбинированной программе ревер + дилей давал откровенную лажу, на
инструмент еще можно поставить на вокал уже нет. Открываю маленький
секрет: на дешевых приборах фирменного звучания можно добиться подрезав
эквалайзером верх у реверберационного хвоста на холле (с комнатами такой
трюк не проходит). Чего от прибора добиться не смог — качественного дабл
трека — если кто поделится секретом буду рад. Подвожу итог — прибор
полюбил всей душой и думаю что до появления дорогого Lexicon он будет
основным на студии. На сведении пару раз пытался использовать другие
приборы в качестве основного ревера — они однозначно проигрывали, так что
если он вам попадется — берите.
Руководстве по эксплуатации Alesis QuadraVerb 2 — вам приходилось его терять? Поскольку вы попали сюда, наверняка с вами это случилось. Но вы не единственный человек, сталкивающийся с проблемами с хранением руководства по эксплуатации всех домашних устройств. Ниже несколько советов, касающихся того, зачем собирать руководства по эксплуатации.
Руководстве по эксплуатации Alesis QuadraVerb 2 это определенный вид технической документации, являющейся неразлучным элементом каждого устройства, которое мы приобретаем. Они отличаются между собой количеством информации, которую можно найти на тему данного устройства: напр. Alesis QuadraVerb 2. Конечно же, если производитель считает что необходимо передать нам большее количество информации, касающейся устройства Alesis QuadraVerb 2, то стоит ее хоть раз прочитать — в начале, сразу же после покупки данной вещи. Однако мы считаем, что инструкции должны заключать самую важную, наиболее необходимую информацию о Alesis QuadraVerb 2, так, чтобы не отнимать желания пользователя прочесть ее уже в самом начале. Несомненно, если устройство Alesis QuadraVerb 2 имеет много продвинутых функций, неизбежно большое количество информации в содержании этого документа.
Które из информации в инструкции Alesis QuadraVerb 2 необходимо обязательно прочитать?
- Информацию, касающуюся правильного использования и ухода за устройством Alesis QuadraVerb 2 — нам необходимо ознакомиться с основными правилами, чтобы в случае проблем с устройством сервисный центр не отказал нам в гарантийном обслуживании, из-за неправильного использования
- Информация, касающаяся самых частых проблем с Alesis QuadraVerb 2 и способы их решения
- Информация, касающаяся гарантии устройства Alesis QuadraVerb 2 и ближайших сервисных центров, способных починить устройство в соответствии с рекомендациям производителя Alesis
Как хранить инструкции дома?
Хорошей идеей является предназначение одного ящика, в котором бы хранилась инструкция Alesis QuadraVerb 2 а также всех других домашних устройств которыми мы пользуемся. Тогда значительно легче вам будет ее найти, чем искать в родных коробках, которые наверняка уже выбросили вы, или другие домочадцы. Раз в год достаточно просмотреть ящик и выбросить инструкции, которые касаются устройств, которыми вы уже не пользуетесь. Таким образом вы избежите хранения ненужных документов, а останутся только актуальные. Вы можете также скачать и распечатать инструкцию Alesis QuadraVerb 2 чтобы разместить ее в своем ящике.

CHAPTER 1 Ð GETTING STARTED
1.1 INTRODUCTION
What It Is
The Alesis QuadraVerb GT is a stereo effects unit that is ideal for guitar. It combines analog and digital electronics to provide the best of both worlds. Analog effects include:
¥Compression
¥Distortion
¥Flat/Presence/Brightness Control
¥Bass Boost
¥Speaker Cabinet Simulator (ideal for use with headphones or recording direct; can be bypassed when feeding a guitar amp)
¥Noise Gate
¥Programmable Effects Loop for inserting other effects (can also provide a signal send from the analog outputs, and receive a return signal into the digital processor)
The digital effects are the same ones that have made the QuadraVerb Plus a favorite in studios and live equipment racks world-wide:
¥Reverb
¥Delay (stereo or mono)
¥Pitch Change (chorus, flange, detune, phaser, etc.)
¥Equalization (graphic or parametric)
¥Panning and Tremolo
¥Ring Modulation
¥Tunable Resonators (a very resonant filtering effect)
¥Sampling (up to 1.5 seconds of sound can be captured and replayed)
The order of the analog effects are preset in their optimum positions; the routing of the digital effects is flexible and programmable. All effects parameters are editable. 100 edited programs can be saved in memory, and called up by front panel switches or MIDI program change commands.
The QuadraVerb GT is also MIDI controllable. Settings need not be staticÑyou can control them in real time with Continuous Controller foot pedals, or with sequencers or keyboards.

1.2SYSTEM HOOKUP BASICS
The QuadraVerb GT is designed for mono or stereo guitar, bass, Chapman Stick, etc. but is also right at home in the studio for processing vocals, drums, pianos, synthesizers (try the rotating speaker sound!), tape tracks, and other instruments.
The QuadraVerb GT can insert between your guitar and subsequent effects units or amplification systems. This lets you use the amp’s overdrive options to further color the QuadraVerb GT’s sound. Or, patch the QuadraVerb GT into an ampÕs effects loop. This lets the QuadraVerb GT process the amp’s internal sound, and in some cases, lets you use the amplifier’s preamp section as an alternate to the QuadraVerb GT’s internal preamp.
Following are some typical hookups, followed by information on proper
2
level-setting. All inputs and outputs are unbalanced lines.
Turn your amplifier volume all the way down when patching the QuadraVerb GT into your system!
AC Transformer Hookup
Plug the QuadraVerb GT’s AC adapter into the wall. The smaller plug inserts into the 9 VAC power jack on the QuadraVerb GT’s rear panel.
To prolong the AC adapter’s life, unplug it from AC power when not in use (turning off the QuadraVerb GT’s power switch does not disconnect the AC adapter from AC power). It’s good practice to plug all your ACpowered devices into a switched power strip, so that turning off the strip turns off power to all your gear.
1.3 AUDIO HOOKUPS
The QuadraVerb GT can interface with a variety of guitar systems and recording studio setups.

1.4 FOOTSWITCH HOOKUP
There are two footswitch jacks on the rear panel that accept standard, normally open, momentary contact footswitches.
A footswitch plugged into the Bypass jack duplicates the BYPASS button function. Press on the footswitch to toggle between bypass and active modes. When bypassed, the LED in the middle of the BYPASS button will be lit.
A footswitch plugged into the Advance jack increments (or decrements)
7
the program number by one with each footswitch press. You can set an upper and lower program number limit, as described in section 5.7.
1.5 EXTERNAL EFFECTS HOOKUP
The QuadraVerb GT offers an effects loop where you can patch in effects other than the ones included in the unit (you might want to insert, for example, a wah-wah pedal or vintage fuzz). The effect can be bypassed or enabled for each patch.
Patch the Effects Loop Send jack to the effect input, and the Effects Loop Receive jack to the effect output. Also note that the Send jack provides a post-analog effects, pre-digital effects send suitable for driving guitar amps or a studio console; the Receive jack lets you plug directly into the digital effects and bypass the analog effects. The effects loop can therefore split the QuadraVerb GT into two separate effects, as described in section 2.1.
It is important to note that turning off the effects loop does not turn off the effects send. Selecting In or Out on the Effects Loop page will only enable or disable the Effects Loop Return jack. Also, the effects loop will be bypassed if there are no jacks inserted, regardless of whether the Effects Loop page is set to On or Off.
8
1.6 SETTING LEVELS
After hooking up your cables, set the proper levels. Start off with your amplifier turned down to a low volume to prevent any ear-shattering surprises as you learn about the QuadraVerb GT. After you know what you’re doing, increase the level to normal monitoring levels.
1.Press the BYPASS button (its red LED will light) so that you hear only the straight guitar sound.
2.Play your instrument and observe the 4-step LED meter toward the left of the QuadraVerb GT.
3.Adjust the Input control so that the -6 dB LED lights consistently but the Clip (red) LED lights rarely, if ever. The red LED indicates that distortion is either about to occur or is actually occurring.
4.Adjust the output control for a comfortable monitoring level. Make sure the output is turned up high enough to provide the amplifier, mixer, or subsequent processor with sufficient level, but not turned up so high that it overloads the unit it is feeding.
5.Press the BYPASS button again so that you can hear the effect of the different QuadraVerb GT programs. BYPASS can be used at any time to toggle between processed and straight sounds.
1.7CHECK OUT THE FACTORY PROGRAMS
The QuadraVerb GT contains 90 programs that put your guitar through serious sonic gyrations. Initially, these programs contain factory presets. However, they can be edited or replaced with your own programs. You can also recall the original factory sound associated with a program location at any time, even if that location has been modified or erased, because the parameters for these programs are stored in ROM (permanent memory).
Assuming you’ve hooked up your guitar as described in the previous section, it’s time to audition the QuadraVerb GT programs and see what this baby can do.
9
Selecting Programs
1.Press the PROGRAM (PROG) button. The LED in the middle of the button will light.
2.There are three ways to select programs:
¥MIDI program changes. See next section.
¥Press either VALUE button to scroll through the available programs (VALUE UP increases the program number, VALUE DOWN decreases the program number). The harder you press the VALUE button, the faster the Program numbers will scroll. Stop on a program, and it will be selected.
¥Key in a particular two-digit program number. Note that the module buttons (REVERB, DELAY, PITCH, etc.) also have numbers printed in gray. These can be used for entering numbers as long as the PROGRAM button is held down.
Example: To enter program 56, press the PROGRAM button and while it is being held down, press the 5 (MIDI) and 6 (CONFIG) buttons. The display will show 56, and that program will be selected.
If you release the PROGRAM button before entering the two digit program number, the program number will revert to what it was before you pressed the PROGRAM button.
The number you enter must be a two-digit number, so enter a Òleading zeroÓ if necessary. Example: To enter program 9, enter 09.
1.8MIDI HOOKUP
MIDI is an internationally-accepted protocol that allows musical-related data to be conveyed from one device to another. See the MIDI supplement if you are not familiar with how MIDI works.
The most popular MIDI applications are hooking up a MIDI footswitch to change programs, and/or a MIDI continuous controller pedal to vary QuadraVerb GT parameters in real time, as you play. The following sections describe how this process works.
10
MIDI Program Selection
The QuadraVerb GT responds to MIDI program change commands. Therefore, sending a particular program number via MIDI to the QuadraVerb GT will call up the program you specified.
If a device can generate program change commands, patching its MIDI Out to the QuadraVerb GT’s MIDI In allows for remote program selection.
MIDI In
MIDI Out
Footswitch
Several devices can generate program change commands:
¥MIDI footswitch This is probably the option that most guitarists will use. A MIDI footswitch sends program changes in response to footswitch presses. Many companies make MIDI footswitches; their manuals explain how to program the footswitch to send out particular program changes.
¥MIDI sequencer A sequencer can record and play back MIDI data, including program change commands.
¥Synthesizer Selecting a new program on a synthesizer usually sends out a corresponding program change command. This allows any signal processor hooked up to the synth to change its settings in response to different synth programs.
¥Other effects boxes If you use more than one effects box, calling up a program on it will often send a corresponding program change through its MIDI Out.
NOTE: Your QuadraVerb GT and the MIDI footswitch must both be set to the same MIDI channel to execute program changes.
11
MIDI Controller Pedal Hookup
Several QuadraVerb GT parameters can be changed remotely over MIDI. Usually this is done with a footpedal that generates MIDI continuous controller data. There are 128 controllers, most of which are available for remote parameter control (some of the higher-numbered controllers are used to set up synthesizer modes and other things we donÕt need to worry about).
The basic idea is to set the parameter to be controlled to a particular controller number. Then set the pedal to the same controller number. As you vary the pedal, it will generate data that will change the QuadraVerb GT parameter. For example, assigning a foot pedal to delay feedback would allow you to kick in a slapback delay at the end of a phrase.
The MIDI controller pedal may be part of your footswitch unit, a separate stand-alone device, or a combination standard volume pedal and converter (e.g., Anatek Pocket Pedal). Synthesizers and other devices also generate MIDI continuous controller data.
If you want to feed the QuadraVerb GT with both a footswitch for program change control and a pedal for real time control, either the footswitch or pedal will need a merging input, or you will need a MIDI merger.

MIDI Thru/Out Hookup
The MIDI Thru/Out jack can have its function changed via software (see section 5.4). When MIDI Thru is turned on, this jack carries a duplicate of the MIDI data appearing at the MIDI In jack. In addition to the Thru function, the Thru/Out jack can then feed the MIDI In of other MIDIcontrolled unit, thus distributing the MIDI signal to two different units.

MIDI Thru/Out

In addition to the Thru function, data generated by the QuadraVerb GT can be sent to other MIDI units. This is more of a feature for advanced MIDI users and is described in sections 5.5 and 5.6 on QuadraVerb GT System Exclusive options (for more information on System Exclusive information, see the MIDI supplement). Generally, the data generated from the QuadraVerb GT is used for one of two purposes:
¥Transfer program data directly from one QuadraVerb GT to another.
¥Send program data to a such as the Alesis DataDisk or other MIDI storage device in order to back up the data inside the QuadraVerb GT.

Play for a while and get a feel for how the QuadraVerb GT sounds. The factory programs give a good idea of what the QuadraVerb GT can do, and can also be modified later on if you want to customize the factory programs to your own specifications.

CHAPTER 2 Ð QUADRAVERB GT MODULES AND CONFIGURATIONS
Many guitarists will find that the 90 factory presets take care of most, if not all, of their musical needs. However, the QuadraVerb GT is a very flexible device and comes into its own when edited to your own specific needs.
To do this, it is necessary to understand the QuadraVerb GT’s effects and configurations, which is what this chapter is all about. The next chapter covers how to edit those effects and configurations.
2.1 ABOUT THE QUADRAVERB GT’s EFFECTS
The QuadraVerb GT has 11 main effects sections (including the mixer) and the ability to alter (modulate) some of the effects parameters in real time. Each effect modifies your signal in a particular way. A particular combination of the 11 effects is called a configuration, as explained in section 2.2.
Preamp
The Preamp section includes effects found in standard rack preamps, such as compression, overdrive, distortion, flat/bright/presence switch, bass boost, cabinet simulator, and noise gate.
This section is followed by a programmable effects loop that lets you insert your favorite classic wah-wah, phase shifter, etc.; you can enable or bypass the effect as part of a program. This loop can also be used to split the QuadraVerb GT into two separate effects (see the last part of this section on ÒBi-TimbralÓ Effects).
Reverb
Reverb is made up of a large number of distinct echoes, called reflections. In a natural acoustic space, each reflection’s amplitude and brightness decays over time. This decaying action is influenced by the room size, the location of the sound source in the room, the hardness of the walls, and other factors.
14
There are five main reverb types, as described later. Furthermore, any reverb type can be gated, which is the process of abruptly cutting off the reverbÕs decay for a more ÒchoppyÓ sound.
Delay
Delay provides a discrete repetition of a signal. By adding feedback within the effect, the delayed signal can repeat many times, with each successive decay softer than its predecessor. The QuadraVerb GT offers four types of delay:
¥Ping-Pong Delay In stereo, the delayed signal bounces back and forth between channels, with the speed determined by the delay time parameter. Maximum delay is 375 milliseconds in QuadMode, 400ms in the Lezlie and Ring Modulation configurations, 750 ms in the Graphic > Delay configuration, 705ms in the 5 Band EQ > Pitch > Delay configuration, and 320ms in the Resonator configuration.
¥Stereo Delay This has two individual delays, one for each channel. Setting them to different delay times allows for polyrhythmic delays. Maximum delay specs are the same as for ping-pong delay.
¥Mono Delay Because this is a single delay line, it has twice the maximum delay time of the stereo delay (up to 1500 ms).
¥Multitap Delay Available only in the 5 BAND EQ > PITCH > DELAY configuration, this delay includes 8 taps with variable delay time, volume, panning, and feedback amount for each tap. The total delay time of all eight delays cannot exceed 1470 ms.
Pitch Change
This module alters the pitch of a signal in various ways to produce ÒanimatedÓ timbres that are more complex than the original signal. The various pitch change options are:
¥Chorus This combines a delayed (typically 10-25 ms), detuned version of the original signal with the straight signal. Modulating the delayed version creates phase, amplitude, and time differences that sound like two instruments playing together. Mono and stereo functions are available; stereo modulates two delayed signals instead
15
of just one.
¥Flanging Flanging is similar to chorusing, but modulates the delayed signal over a much shorter delay range (typically 0-12 ms). This produces a Òjet airplaneÓ-like sound. Mono and stereo flanging is available, and the flange modulation sweep can be triggered in order to sync up with the rhythm of your playing.
¥Detune Shifts the pitch by a fixed amount. This creates a thickening effect similar to the difference between a 12-string and 6-string guitar.
¥Phase Shifter This effect is similar to flanging, but covers a narrower delay range and has a more diffused timbral quality.
¥Lezlie Speaker Simulator With the Lezlie configuration selected, the pitch change module becomes a rotating speaker simulator. Rotating speakers, which involved mechanically rotating one or two speakers to produce complex timbral changes, were extremely popular during the 1960s.
Equalization
Equalization provides control over the tone of your signal by altering the frequency response in various ways. The QuadraVerb GT’s three different types of EQ are:
¥3 Band Parametric This combines high and low frequency shelving equalizers (like the tone controls found on stereo systems and guitar amps) along with a sweepable midrange parametric stage (see Ó5 Band Parametric,Ó next) that has variable boost or cut, frequency, and bandwidth (resonance, or ÒbiteÓ). This works well for dialing in rhythm guitar sounds.
The high and low shelving bands offer two parameters, amplitude and frequency. Amplitude sets the amount of boost or cut; frequency sets the frequency at which the maximum boost or cut occurs. This boost continues for frequencies higher than the high frequency and lower than the low frequency.
16
The middle band is parametric and offers amplitude, frequency, and bandwidth parameters as described next.
¥5 Band Parametric This is identical to the 3 Band Parametric but offers two additional sweepable midrange stages with variable boost or cut, frequency, and bandwidth. The following diagram shows the relationship between three parameters.
The complex response of the 5 band parametric lets you compensate for dead spots on a guitar’s neck, or set up a very specific frequency response.
¥11 Band Graphic The graphic equalizer can boost or cut any of 11 different bands (16 Hz, 32 Hz, 62 Hz, 126 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz.
17
Panning and Tremolo
Panning shifts the signal back and forth between the stereo outputs at a cyclical, adjustable rate. Tremolo provides a ÒpulsingÓ sound via cyclical level changes. Both have ÒdepthÓ parameters; with panning this varies the width of the pan in the stereo field, with tremolo this sets the difference between volume peaks and valleys.
Ring Modulation
Ring modulation shifts a signal’s harmonics up and/or down by an adjustable frequency (expressed in Hertz). The QuadraVerb GTÕs ring modulator features individual outputs for the up and down signals. The resulting sound takes on a Òclangorous,Ó bell-like quality that is used mostly with percussive effects. Try this on a drum machine, or muted guitar parts.
Tunable Resonators
A resonator is a filter whose response is so sharp that it actually imparts a pitch to any signal going through it. In the Resonator configuration, there are up to five resonators, depending on the configuration, so you can tune the resonators to complex chord types. You can also transpose the resonator frequencies via MIDI notes to match a particular chord progression.
Sampling
Sampling is the process of digitally recording a signal into the QuadraVerb GT’s memory, which can then be triggered via an external audio input (e.g., a snare drum sound coming from a tape track), a front panel button, or a MIDI note. Different MIDI notes will transpose the sample. Sampling is useful if you want to capture a particular effect or chord change, then play over it. Try it in the studio for drum sound replacement, reproducing unusual vocal effects, etc.
Mixer
The multiple effects are all placed in parallel. Each effectÕs output feeds a
18
mixer, and is variable so that you can change the balance of that particular effect with respect to the overall sound.
The effect input can come from the main input if you only want the effect to process the dry sound, but in many configurations, the effect can get its input from the output of other effects, or from a combination of processed and dry sounds.
Modulation
As mentioned earlier, many QuadraVerb GT parameters can be changed in real time via pedals that generate continuous controller commands, or from commands issued by a sequencer or synthesizer. Continuous controller pedals are available from a variety of manufacturers at various price points. These generate signals that are ÒtaggedÓ with a particular controller identification number. If you set a QuadraVerb GT parameter to be controlled by this particular controller number, moving the pedal will change the QuadraVerb GT parameter.
Modulation consists of choosing up to 8 ÒtargetÓ parameters to be modulated by any one of several types of MIDI ÒsourceÓ data types (pitch bend, aftertouch, note number, and note velocity as well as continuous controllers). Several parameters can be changed by one controller, so that, for example, moving a pedal could increase chorus depth and boost the midrange frequencies.
ÒBi-TimbralÓ Effects
The QuadraVerb GT can serve as two separate effects units by proper patching to and from the effects loop. For example, consider a situation where a guitarist plays guitar and sings. Plug the guitar into the QuadraVerb input; the effects loop send provides the post-analog effects signal, which can be routed to a guitar amp. Meanwhile, the voice mic can be externally preamplified and sent into the effects loop return. This allows the vocal to be processed by the digital chorus, reverb, equalization, etc. sections. The QuadraVerb GT output, which now carries only the processed vocal sound, can be routed to a PA for further amplification.

2.2 ABOUT CONFIGURATIONS
No matter which program you select, the analog effects are always in the same order. However, the digital effects can be connected together in one of eight different ways, each of which is called a configuration. A configuration doesn’t just include a specific collection of effects, but also the way in which they interconnect (e.g., whether the delay signal is derived from an equalized or non-equalized signal). This allows for a great deal more flexibility than you would expect from a fixed configuration of effects.
This flexibility allows for some great sounds, but also requires a bit of experimentation to learn the subtleties of each configuration and how these subtleties affect the sound. It’s probably easiest to start off by ÒtweakingÓ the factory presets to learn what the different parameters do, then graduate to creating programs from scratch.
These configuration descriptions use block diagrams to indicate signal flow. Keep the following in mind:
¥Think of the connecting lines as Òpatch cordsÓ between different Òeffects boxesÓ (the individual modules).
¥Switches are enclosed in rectangular boxes with rounded corners.
¥The knobs act as volume controls if two wires hook into the knob, or mix (ÒpanÓ) between two signals (incoming wires) and provides an output (outgoing wire) if three wires hook into the knob.
¥Heavy lines indicate a stereo path. Note that most effects output a stereo signal, but accept a summed, mono signal at the input.

QuadModeª is a complex configuration that offers comprehensive switching and mixing possibilities. ItÕs excellent for creating larger-than- life, animated sounds.
The Pitch module can switch its input between the preamp or EQ signals. The Delay moduleÕs Delay Input Mix control chooses a blend between the output of the Pitch module, or the preamp or EQ signal (as selected by the Delay Input 1 switch).
The Reverb moduleÕs Reverb Input Mix control chooses a blend between two input options. Reverb Input 1 switches between preamp, EQ, preDelay, or post-Pitch signals; Reverb Input 2 switches between the postDelay or post-Pitch signal.
Panning and Tremolo are available in this configuration, and are in series with the preamp or EQ signal line. The Preamp Signal Pre/Post EQ switch chooses whether the Preamp Output comes from preamp or EQ.

This is similar to the QuadModeª configuration, but replaces the EQ and Pitch modules with a Lezlie (rotating speaker simulator) module and does not have a Preamp level control.
The Lezlie module simulates the common two-speaker system with two different speeds. The switching and mixing options are similar to those used in QuadMode. This configuration produces complex frequency and amplitude modulation effects and works very well with rhythm guitar.

This is just the ticket for rich chorus sounds. Use the 5 Band EQ to shape your timbre, Pitch Change to add chorusing (or other pitch effects such as flanging, etc.), and Delay to add evocative echo effects. Using the Multi Tap option in the Delay module creates unusual echo effects along with chorusing.
The Pitch module can switch its input between preamp or EQ signals. The Delay moduleÕs Delay Input Mix control chooses a blend between the output of the Pitch module, or the preamp or EQ signal (as selected by the Delay Input 1 switch).
23
Multi Tap delay is also available in this mode along with the standard mono, stereo, and ping-pong delays. Up to eight taps are available along the delay line; each tap has variable delay time, panning, volume, and feedback. For more details about multitap delays, see section 4.5.
Panning and Tremolo are available in this configuration, and are in series with the EQ signal line. The Preamp Signal Pre/Post EQ switch chooses whether the Preamp Output comes from before or after the EQ.

This is the recommended configuration when you want the best possible reverb sound. By restricting the number of effects, the QuadraVerb GT can devote its full computing power to creating awesome reverberation effects. However, EQ is still available for additional tone shaping, as is a simpler version of chorusing.

This configuration features the Ring Modulation in conjunction with Delay and Reverb. The Ring Modulator is not available in other configurations.
The Ring Modulator produces two outputs, both of which are mathematically derived (sum and difference frequencies) from the input signal. The Ring Modulator output can pan between these two output signals, as can the Delay & Reverb Shift Mix control, which chooses a blend of both outputs to send to the Delay and Reverb inputs.

CHAPTER 3 — BASIC EDITING
TECHNIQUES
Editing is the key to using the QuadraVerb GT to its fullest potential. If you like a sound but want more reverb, less treble, more distortion, or whatever, editing is the answer.
Make sure that if you develop a custom set of programs, that you save your data to some form of MIDI system exclusive storage device, like the Alesis DataDisk (see sections 5.5-5.6).
3.1 HOW EDITING WORKS
The QuadraVerb GT contains five Effects Groups, each with its own corresponding front panel selection button: Reverb, Delay, Pitch, Equalization (EQ), and Guitar Preamp (Pre-Amp). These all contain editable parameters. Four other editable functions (with front panel buttons) are also available: MIDI, Name/Mod, Mix, and Configuration. The basic editing procedure is the same for whatever you want to edit; weÕll get into specifics later.
1. Select What You Want to Edit
Push the button associated with the Effect Group (Reverb, Delay, Pitch, EQ, Preamp) or function (MIDI, Config, Mix, Mod) you want to edit. The LED in the middle of the button will light.
2. Select the Page with the Parameter to be Edited
Each effect/function includes several pages. Each page shows the name and value of one (or sometimes more) parameters, and each parameter controls some particular aspect of the QuadraVerb GTÕs sound or operation. Most effects or functions require multiple pages to show all available parameters.
The page’s upper display line shows the parameter name, and the lower line, the parameter value. Press the PAGE UP and DOWN buttons to select a page containing a parameter to be edited. The harder you press the PAGE button, the faster the pages will scroll.
NOTE: The NAME/MOD button is the exception to this rule,as it
27
accesses both program name parameters as well as the QuadraVerb GT’s MIDI modulation parameters. (See section 3.4)
3. Change the Parameter’s Value
A parameter’s value is like the Òcalibration scaleÓ a knob would point to on a regular guitar effects box, except instead of setting a physical device to a certain position, you see the parameter setting on the screen and adjust its value with a pair of buttons (increase/decrease value). For example, a volume knob on a guitar amplifier might be set to 5 would be the same as a volume parameter with a range of 00-99 set to 50. In either case, the control is set halfway.
A small line under a parameter indicates it can be edited. Use the VALUE buttons to change a parameter’s value. The harder you press the VALUE button, the faster the values will scroll.
4. Edit More Parameters
Repeat steps 1-3 until all the parameters you want to edit have been edited.
Notes
¥All edits are not made to the original program, but to a copy of the program that resides in a special place in QuadraVerb GT memory called the Edit Buffer. A decimal point to the right of the program number indicates that you are listening to an edited program in the Edit Buffer. You must save an edited program by transferring the edit buffer contents into the original program memory location before selecting another program, or your edits will be lost.
¥Each parameter has a default value that works well in most applications. To return to this value, press both VALUE buttons simultaneously. See chart on page 113.
28
3.2 COMPARING EDITED AND NON-EDITED VERSIONS OF PROGRAMS
Editing a program does not change the original version permanently until it is stored (see section 3.3 below). Because your edited version is separate from the original, you can compare the two versions without altering the original. This can be very useful if you ÒovereditÓ a program and want to see if the edited version really does represent an improvement over the original program. To compare:
1.Press the PROG button.
2.Press the PAGE UP button. The display says * COMPARING * and you can hear the program you started with.
3.To exit compare mode, hit any button except a VALUE button. IF
YOU PRESS A VALUE BUTTON, YOUR EDITED VERSION WILL BE LOST.
3.3SAVING (STORING) EDITED PROGRAMS
1.To save an edited program, press the STORE button. The LED in the middle of the button will light. The display says:
STORE PROGRAM AT
LOCATION: XX
Éwhere XX is the original program number.
2.To save to a different program number, press the appropriate VALUE button to select the desired program location.
Warning! This edited program will overwrite the program stored in this location. Before saving, make sure the program to be overwritten is expendable.
3.Press the STORE button a second time to save the program. The display will say PROGRAM STORED.
29
3.4 RENAMING PROGRAMS
You may want to give your edited program a distinctive name.
1.Press the NAME/MOD button. The LED in the middle of the button will light and the display says:
EDIT NAME: Ò(Name of Song)Ó
2.Use the PAGE buttons to select the character to be changed. Characters available (in addition to a blank space, Yen symbol, and left and right arrows) are:

3.Use the VALUE buttons to select the desired character. To enter a space, press both VALUE buttons simultaneously (or press the DOWN VALUE button and scroll to the last character of the character list, which is a blank space).
4.Repeat steps 2 and 3 until the program is named.
6.To store the name, press the STORE button twice.
7.Press any button other than PAGE or VALUE to exit the Name page.
3.5 RECALLING INDIVIDUAL FACTORY PROGRAMS
1.Press STORE. The LED in the middle of the button will light.
2.Press the PAGE UP button to select the Recall page. The display says:
30
RECALL ALESIS
PROG YY INTO XX
3.Press either VALUE button to select the program to be recalled (the first parameter).
4.Press the PAGE UP button again to move the cursor under the second parameter.
5.The factory program will be recalled into the program selected as the second parameter. Press either VALUE button to select this program number.
6.Press STORE to complete the recalling operation.
3.6RECALLING ALL FACTORY PROGRAMS
1.Press STORE. The LED in the middle of the button will light.
2.Press the PAGE UP button three times. The display says:
RECALL ALL 90
ALESIS PROGRAMS
3. Press STORE and all the program locations will be occupied by factory programs. Any other data will be overwritten.

Alesis Quadraverb господствовал на рынке рэковых процессоров конца 80-х и начала 90-х годов, и по сей день его можно найти в бесчисленных гитарных педалбордах, студиях и установках живого звука. Долговечность «квадов» является свидетельством их выдающегося качества звука и легко редактируемых эффектов.
Начиная с обновления Quad, Quadraverb Plus, среди прочих функций появилась Multi Tap Delay, что позволило Чарли Холлу разработать настройки для имитации старых ленточных эхо-устройств начала шестидесятых, которые использовали The Shadows и многие другие группы тех дней.
QUADRAVERB
Alesis QuadraVerb — это стереофонический программируемый блок эффектов с полосой пропускания 16Гц-20кГц и четырьмя цифровыми эффектами (EQ, Pitch Change, Delay, Reverb). Эффекты могут использоваться параллельно или последовательно (или в комбинации).
QUADRAVERB PLUS
QuadraVerb Plus — это усовершенствованная версия оригинального QuadraVerb. Многие новые функции, которые теперь доступны, стали возможны благодаря простому обновлению программного обеспечения.
QUADRAVERB GT
Alesis QuadraVerb GT — это стереоэффект, который идеально подходит для гитары. Он сочетает в себе аналоговый предусилитель и цифровую электронику, чтобы обеспечить лучшее из двух миров.
QUADRAVERB 2
Процессор мультиэффектов Alesis Q2 обладает безграничными возможностями для настройки для тех, кто отдаст свое время и силы для достижения потрясающих высот в области звуковых эффектов. Это высокопроизводительное оборудование, с простой в использовании операционной системой и широким информативным ЖК-дисплеем.
QUADRAVERB 20
Q20 — это, по сути, Q2, оснащенный 20-битными преобразователями, но он также был улучшен в других областях, не в последнюю очередь за счет вдвое большего количества пользовательской памяти.
