Most Preset Programs route the LR IN signal to the LR OUT.When connecting to a mixers aux sends and returns. the Global Direct Signal Mute should be set to ON.
To remove all direct routings of inputs to outputs on all Programs simultaneously:

Press [GLOBAL].

The [GLOBAL] LED will be lit.
Press [< PAGE] once. This selects Global Page 9. The display will read:
GLOBAL DIRECT SIGNAL MUTE: OFF Turn the [VALUE/ENTER] knob to the right until the display reads ON.
The next Program recalled which has the inputs routed to the outputs will not display the patch cords for these connections nor will you hear any direct uneffected signal at the outputs.
Mono In - Stereo Out. If you only want to feed the QuadraVerb 2 a mono input, but wish to connect both of its outputs back to the mixer, you will need three 1/4" audio cables. Connect a cable from an effect send to the [R] INPUT of the QuadraVerb 2, another cable from the [L] OUTPUT of the QuadraVerb 2 to an effect return or other mixer input, and another cable from the [R] OUTPUT of the QuadraVerb 2 to an adjacent mixer input.

Stereo In - Stereo Out. This connection is similar to the one described above. However, by utilizing two sends from the mixer, we add one more cord and can now send a stereo signal to the QuadraVerb 2s inputs. Example, if you connected effect sends 3 and 4 to the [L] and [R] INPUTS, and had a stereo instrument (such as a keyboard) connected to two channel inputs of the mixer (either one panned hard left and hard right), you would send the left channel to send 3 and the right channel to send 4. Alternatively, you could have two discrete effect sends between the Left and Right channel, and process each separately within the QuadraVerb 2. For example, the Left channel (from send 3) could be a chorus, and the Right (from send 4) could be a reverb. This is similar to Dual Mono, described earlier.

Using Inserts

By using individual channel inserts, you can dedicate the QuadraVerb 2 to a specific channel (or pair of channels) on the mixer. The Insert connections on the back of the mixer provide a way of inserting external processing equipment into the signal path. The insert occurs after the input amplifier, and before the main fader; essentially it is the same as connecting the source (instrument or microphone) into the QuadraVerb 2 before the mixers channel input. However, some mixing consoles inserts come after the EQ section, and may therefore be different from the original signal.

Usually, insert connections require a special, stereo-splitting Y-cord to be connected (one stereo plug provides both send and return while two mono plugs connect separately to an input and output). These are known as TRS connectors (tip-ringsleeve). The tip of the stereo plug typically carries the send or output of the insert jack, while the ring carries back the return. The sleeve represents a common ground for both signals. Check the manual of your mixer because some are wired differently (for example, having two separate jacks for send and receive). Mono. This involves connecting a 1/4" TRS (tip-ring-sleeve) to the Insert jack of a single channel on a mixing console. The other end of the cable (which splits into two, 1/4" mono connectors) are connected to the [R] INPUT and [R] OUTPUT, respectively. If you do not hear any audio after making these connections, swap the input and output cables at the QuadraVerb 2, as these may be wired backwards. If the cable is color-coded, usually the red jack represents the send (which connects to the QuadraVerb 2s INPUT) and black is the return (which connects to the OUTPUT).

Insert

Stereo. In the case where a stereo instrument, such as a keyboard or sampler, is connected to two separate channels of a mixing console, you will need two 1/4" TRS cables, one for each channel. The connection is made in a similar fashion as described above.

Left Master Insert

Right Master Insert

Using Main Outputs

When you want to effect everything on the mixer, you can connect the QuadraVerb 2 between the mixers outputs and the amplifiers or tape machines inputs. This is done by using two 1/4" cables to connect the Left and Right Main Outputs of the mixing console to the [L] and [R] INPUTs of the QuadraVerb 2. The [L] and [R] OUTPUTs of the QuadraVerb 2 are then connected to a stereo amplifier, or two input channels of another mixing console (for sub-mixing applications).

Avoiding Ground Loops
In todays studio, where it seems every piece of equipment has its own computer chip inside, there are many opportunities for ground loop problems to occur. These show up as hums, buzzes or sometimes radio reception, and can occur if a piece of equipment sees two or more different paths to ground. While there are methods to virtually eliminate ground loops and stray radio frequency interference, most of the professional methods are expensive and involve installing a separate power source just for the sound system. Here are some easy helpful hints that a professional studio installer might use to keep those stray hums and buzzes to a minimum.

To connect the QuadraVerb 2s MIDI ports to another MIDI device:
Connect a MIDI cable from the QuadraVerb 2s MIDI [THRU/OUT] connector to the
MIDI IN connector of the other MIDI device.
Connect another MIDI cable from the QuadraVerb 2s MIDI [IN] connector to the other MIDI devices MIDI OUT connector.
For more information about MIDI, refer to chapter 6.

Alesis Optical

The Alesis Optical interface provides two EIAJ fiber optic connectors for [DIG IN] and [DIG OUT]. These connectors use a proprietary Alesis multichannel format first introduced with the ADAT Multitrack Recorder. The QuadraVerb 2 can send and/or receive digital audio directly to/from an ADAT (or other devices which use the same optical interface). Digital connections provide better fidelity than the analog inputs and outputs. The proprietary Alesis Optical format carries up to 8 audio channels on a single fiber optic cable. Since the QuadraVerb 2 has two channels (left and right), you may choose two of the incoming 8 channels for the QuadraVerb 2 to process. The QuadraVerb 2s Left and Right Outputs can then be routed in the digital format using any two channels (they dont have to be the same as the input channels). Fiber optic cables of various lengths are available from your Alesis dealer. The shorter the cable, the better. The OC cable is 5 meters long (16'4") and is the maximum length recommended.

Footswitches

On the rear panel you will find two footswitch jacks labeled [ADVANCE] and [BYPASS]. Any momentary single-pole/single-throw footswitch, normally open or normally closed, will work for the two footswitch functions. These should be plugged in prior to power-up so that the QuadraVerb 2 can configure itself for the type of footswitch being used.

Advance

The [ADVANCE] jack lets you scroll through the Programs in memory by advancing to the next higher numbered Program each time the connected footswitch is pressed. The QuadraVerb 2 will wrap-around whenever it reaches the end of available Programs and the Advance footswitch is pressed again. You can set a range of Programs to be used, thereby cutting off other Programs from being recalled in this manner. For example, if you set the range to be User 10 through User 24, only Programs within this range will be recalled using the Advance footswitch. If Program 24 is selected and the footswitch is pressed again, Program 10 is recalled.

97: Guitar Rack

This Program includes two Pitch Blocks feeding a delay Block, into another Pitch Block, then into a Reverb Block, and finally yet another Pitch Block. This is a prime example of the flexibility the QuadraVerb 2 offers to programmers. The Program creates a thick, swirling, ambient effect that greatly enhances an electric guitars sound. The R IN is routed to Blocks 1 and 2, as well as the L and R OUT. The first two Pitch Blocks are defined as Pitch Detune type, but are set to different detune amounts to create a thicker sound. The Delay Block is a Mono Delay which provides a very quick slap back by using a small delay time and no feedback. The third Pitch Block provides a Stereo Chorus which swirls the detuned, delay signal and feeds directly to the outputs. The Delay Blocks output is also fed into a Hall 1 Reverb which provides ambience to the un-chorused signal. The Reverbs stereo signals are routed to the QuadraVerb 2s outputs and mixed with the Stereo Choruss signals. Meanwhile, the Reverbs mono output feeds a Stereo Flanger whose stereo signals are also combined with the Stereo Chorus, Reverb and the original input signal at the outputs. Again, use the Mix parameters to create just the balance you want.

98: Stereo Plates

This Program is very simple. It routes the L and R IN through separate stereo type Reverb Blocks (Plate 1 type, to be precise). Both stereo signals coming out of the two Reverb Blocks feed the LR OUT. This creates a very clean stereo reverb effect thats great for vocals. Play around with the Predelay and Decay parameters to adjust the attack and length of the reverb.

Adjusting Effects Levels

Although we may not want to get started editing Programs just yet (thats left for chapter 4), it is usually necessary to have immediate control over the output levels of each Effect Block, as well as the amount of direct level going from the inputs to the outputs. These are found within Mix mode. To adjust a Programs effect levels:

Press the [MIX] button.

The [MIX] buttons LED will light.
Use the [< BLOCK >] buttons to select any of the active Blocks in the display. If the selected Block is routed to the LR Outputs, the display will read:

LEVEL TO L/R:RVB=100%

The letters RVB in the display example above indicate the selected Block is of the Reverberation type. Other types are: EQ for Equalization, PCH for Pitch and DLY for Delay.
Turn the [VALUE/ENTER] knob to adjust the Blocks Level to the LR Outputs,
from 0100%. If the selected Block is not routed to the LR Outputs, this setting will be NONE and you will not be able to adjust the value.

What is a Block?

A Block is essentially a discrete effects processor that can be used alone or in conjunction with other Blocks. Each Block has a Mono input and up to three outputs (depending on its type): left, right and mix. A Block requires that a signal be routed to it before it can effect the signal. The Block must also have its output connected either to the L OUT or R OUT (or both), or to the input of another Block (or to a series of Blocks) which is in turn connected to either the L OUT or R OUT (or both) before the Blocks effect can be heard. The four effect functions available in a Block are: Equalization, Pitch, Delay and Reverberation. Each one of these has several effect types. Example: Once a Block is assigned to use a Pitch function, you can choose a Chorus, Pitch Shifter, Flanger, etc. A full list of all the available effects and their parameters is shown in Chapter 5.
Selecting and Editing Blocks
Editing a Program is done by first selecting one of the eight Blocks, and then selecting a Block function (Type, Routing, Parameter, or Mix). Use the [< BLOCK >] buttons to move the pointer in the display to the left or right. The pointer appears as a down-pointing triangle just above the Blocks, thereby selecting one of the eight Blocks or the L OUT or R OUT (the L OUT and R OUT are special Blocks which arent really edited, except when adjusting the mix). The pointers position indicates which Block is being edited. There are four Block functions, which are accessed by using the four Block function buttons: [TYPE], [ROUTING], [PARAMETER], and [MIX]. Pressing any of these buttons takes you to its related parameters, and simultaneously turns on the buttons LED to indicate the selected Block function. TYPE. The Type function is where you go first to define a Block. A Block is defined as either EQ, Pitch, Delay, Reverberation or Off. This is done in Type Page 1. Once a Block is defined, its effect type can be selected. This is done in Type Page 2. If you need to move a defined Block to another position, you would go to Type Page 3. ROUTING. Once a Block is defined, you must select its input source and route its outputs either to another Blocks input or to the L OUT or R OUT. This is done in Routing Page 1. Once an input source is selected, you can adjust its level feeding to the Blocks input using Routing Page 2. If you decide to delete a routing that has already been added, you will use Routing Page 3.

Chapter 3 - Overview

PARAMETER. This is where you adjust the selected Blocks parameters. The number of pages available and the parameters found in them will be determined by the Blocks type. Some effect types have only one or two parameters on a single page; while other effect types (particularly reverbs) use all nine pages, with as many as four parameters on a single page. MIX. The Mix function provides three parameters on three separate pages. When a defined Block is selected, Mix Page 1 lets you adjust its level going to the LR Outputs. Page 2 lets you adjust the Direct Signal Level, and Page 3 lets you adjust the Master Effects Level. If, however, an undefined Block is selected, or the LR OUT is selected, there will only be two pages available in the Mix function (Direct Signal Level, and Master Effects Level). Once a Block function is selected, use the [< PAGE >] buttons to scroll through the various pages within a Block function. The number of available pages will vary from function to function. The left side of the display will indicate the total number of pages within the selected Block function. The page currently being displayed will be underlined. When you find a parameter you wish to edit, turn the [VALUE/ENTER] knob until the desired value is displayed. If the new value flashes in the display, it means you must press the [VALUE/ENTER] button to select the new value.

Use the [< BLOCK >] buttons to select the EQ Block we just created.
If you just finished the previous tutorial, the EQ Block should already be selected. The IN LR is not selectable as a Block.
Press [ROUTING]. The [ROUTING] buttons LED will light and the display will read:
ADD ROUTE FROM: INPUT LEFT
The cursor appears under the setting (INPUT LEFT) which is flashing.
Turn the [VALUE/ENTER] knob to scroll through the various options.
The choices are INPUT LEFT, INPUT RIGHT or EQ 1 MIX. As you scroll through, notice the flashing patch cord which appears in the lower display connecting IN L to EQ IN or IN R to EQ IN or M out to EQ IN, depending on which option you are viewing in the upper display.
All three options are routed to the EQ Blocks input, so their nomenclature is determined by their source, i.e. FROM INPUT LEFT, FROM INPUT RIGHT, etc.
With the INPUT RIGHT option selected, press the [VALUE/ENTER] button.
This connects the signal from the Right input of the QuadraVerb 2 (IN R) to the input of the EQ module.
Upon pressing the [VALUE/ENTER] button in step 3, the display automatically advances to Page 2, which is where we may set the level of this connection (the volume from the right input to the EQ in). The display now reads:
LEVEL FROM: INPUT RIGHT = -6.0dB
The patch cord will still flash until a level has been dialed in.
Turn the [VALUE/ENTER] knob to select the input level for this

connection.

Level Setting
The input level is an important parameter, the setting of which can have a drastic impact on the resulting effect. Its default setting of -6.0dB represents the halfway point of its range. 0 dB is the loudest using no attenuation, while OFF mutes the route entirely. You should set the level to accommodate the headroom the effect will need. For example, even if the front panel input levels are below clipping, if you boost an EQ band, it can distort the internal processor of the Q2. The -6.0 dB setting will accommodate most blocks, but if there is clipping internally (when the red LED's flash
on input), lower the input level. You may also need to lower the routing level if a block is receiving signal from more than one source. On the other hand, the best signal-to-noise ratio is achieved when signals are as loud as possible without clipping. In the case of a one-block program, the routing from the block to the L and R outputs should be at 0.0 dB. Multiple-block programs will need lower settings to avoid clipping at the output blocks.

Output Level

This controls how much signal we are returning to our mixing console, or whatever else its connected to. Matching levels throughout the recording/mixing chain will allow us to get the cleanest possible recordings.

LED Meter

This is a visual indicator of level. It is a four step LED (light emitting diode) ladder with steps at -32dB, -12dB, -3dB (green LEDs), and the red LED indicating CLIP. The dB markings refer to how much headroom is remaining before overload. As with all meters, a certain amount of experimentation is necessary before you feel comfortable, as different types of signals with sharper attack times will affect the LEDs differently. The meters have several sources, so they can detect overloads caused by internal gain or feedback, as well as by the [INPUT LEVEL] controls. Internal clipping is shown when the red LEDs flash; if the red LEDs flash while the -3 LEDs do not light, the levels within the QuadraVerb 2s program should be lowered.

Display

The QuadraVerb 2 is equipped with a custom LCD display, which provides (among other things) a complete view of the signal routing used by the current Program.

ADVANCED APPLICATIONS

MIDI Functions

The QuadraVerb 2 provides many MIDI functions, including being able to respond to program changes, sending and receiving Program information via SysEx dumps, and realtime control over various effect parameters via MIDI controllers. For more information about basic MIDI connections, see chapter 1.

Global MIDI Channel

The Global MIDI Channel is used to receive program change messages, as well as other MIDI events for use with the realtime modulation capabilities provided in the QuadraVerb 2. To set the QuadraVerb 2s MIDI channel:

Press [MIDI].

The [MIDI] LED will light and the display will read:

MIDI CHANNEL: 1

Turn the [VALUE/ENTER] knob to set the Global MIDI Channel to either 1 through 16, or OMNI (all 16 channels simultaneously).
Receiving Program Changes
In order to recall programs or control parameters on the QuadraVerb 2 from a MIDI control device (keyboard, drum pad, guitar or bass controller, sequencer, etc.):
Connect the control devices MIDI OUT to the QuadraVerb 2s [MIDI IN].
This provides a one-way connection, since this is all we need to control the QuadraVerb via MIDI (we dont require the QuadraVerb to send MIDI information back to the other device).
Press [MIDI]. The [MIDI] LED will light.
Press [PAGE >] to access MIDI Page 2.
MIDI PROGRAM CHANGE: OFF Turn the [VALUE/ENTER] knob to turn MIDI Program Changes ON.

GEN 1 PEAK FOLLOWER GAIN: x 1
The cursor appears beneath the Generator, indicating that you may now turn the [VALUE/ENTER] knob and select either Input Generator 1 or 2, depending on which one you want to edit.
Press [PAGE >] to advance the cursor to the next field, and turn the
[VALUE/ENTER] knob to adjust either the Envelope Attack Threshold (-32 to +0dB) or the Peak Followers Gain (x1 to x99).
Press [PAGE >] to advance to page 7.
GEN 1 ENV REL. THRESHOLD: +0dB
GEN 1 PEAK FOLW. DECAY: 0.20Sec
Again the cursor appears beneath the Generator, indicating that you may now turn the [VALUE/ENTER] knob and select either Input Generator 1 or 2, depending on which one you want to edit. Press [PAGE >] to advance the cursor to the next field, and turn the [VALUE/ENTER] knob to adjust either the Envelope Release Threshold (-50 to +0dB) or the Peak Followers Decay Time (from 0.20 to 10.00 seconds).
If the selected Input Generators type is input envelope:
Press [PAGE>] to advance to Page 8.
GEN 1 ENV ATTACK TIME: 0.00Sec
PRESS [PAGE>} to advance the cursor to the next field and turn the [VALUE/ENTER] knob to adjust the input envelopes attack time (0.00 to 10.00 seconds). This controls the rate that the envelopes control will affect the selected target parameter once it has crossed the attack threshold. Press [PAGE>] to advance to Page 9. If the selected Input Generator's type is Input Envelope, the display will look like this:
GEN 1 ENV RELEASE TIME: 0.00Sec
Press [PAGE>] to advance the cursor to the next field, and turn the [VALUE/ENTER] knob to adjust the input envelope's release time (0.00 to 10.00 seconds). This controls the rate that the envelope's value will fall after the source level has crossed the release threshold.

Footswitch Controls

Two footswitch jacks, [ADVANCE] and [BYPASS], are provided on the back panel of the QuadraVerb 2.

Program Advance

The [ADVANCE] jack allows the QuadraVerb 2s Programs to be advanced remotely from a footswitch. The Program numbers included can be selected by setting the Footswitch Range, found on Global Page 2. The range can be as small or large as you like, including either the Preset or User banks or both. Example: If the Footswitch Range is from Preset 89 to User 14, the Programs will continuously cycle from Preset 89 to User 14 whenever the Advance footswitch is triggered. To set the Footswitch Range:

The [GLOBAL] buttons LED will light.
Press [PAGE >] to advance to Global Page 2. The display will look like this:
FOOTSWITCH: 00 Pset TO 00 Pset Turn the [VALUE/ENTER] knob to select the Program number to be the
beginning point of the Footswitch Range (Preset 0099 or User 0099).
Press [PAGE >] to advance the cursor to the next field, and use the
[VALUE/ENTER] knob to select the Program number that is to be the end point of the Footswitch Range. When the last Program of the Footswitch Range is reached and the Advance footswitch is pressed again, the first Program in the Footswitch Range will once again be selected.
The [BYPASS] jack allows you to bypass the effects of the QuadraVerb 2 via a footswitch. This is the same as pressing the [BYPASS] button on the front panel. Each time either the [BYPASS] button is pressed, or the footswitch connected to the [BYPASS] jack is pressed, Bypass mode is toggled on and off again. When Bypass mode is turned on, the [BYPASS] button's LED will be lit.
In order for Bypass mode to function correctly, make sure the LR Inputs are routed to the LR Outputs, and the Global Direct Signal Mute function is turned off. If the inputs are not routed directly to the outputs, the [BYPASS] button acts more like a mute since nothing will be heard when it is enabled.
Controlling Delay Time via Tap Tempo
When using either of the two Delay types which allow for tap tempo adjustments of delay time, either of the two footswitch jacks may be assigned to provide tap tempo control. This is an alternative way of setting the delay time of a tap tempo type delay rather than tapping the [VALUE/ENTER] knob. This can be a great utility for live applications, where the delay time can be adjusted to match your playing tempo simply by tapping your footswitch to the beat of the music. To select either the [BYPASS] or [ADVANCE] footswitch to control tap tempo:
Press [PAGE <] twice to move to Global Page 8. The display will read:
footswitch jack, depending on which one you wish to use to control tap tempo. When either BYPASS or ADVANCE is selected, that footswitch will not perform its normal function until the Tap Tempo Footswitch parameter is set to the other footswitch jack or to NONE.

Alesis Optical Interface - Chapter 7

CHAPTER 7

ALESIS OPTICAL INTERFACE

Overview

The Alesis optical digital interface provides the means to communicate with other digital audio devices, such as the Alesis ADAT Multitrack Recorder. The Alesis optical interface uses a proprietary 8 channel buss, from which the QuadraVerb 2 can provide processing for 2 channels. This means you can come into the QuadraVerb 2s digital input from one or two tracks of an ADAT, and go out of the QuadraVerb 2s digital out to one or two ADAT tracks. Alternatively, you may wish to use the QuadraVerb 2s analog inputs to process an instrument and record digitally direct to ADAT. This is possible because while the QuadraVerb 2s inputs are set to either analog or digital, both its analog and digital outputs are always active. However, you must determine which 2 channels (of the digital buss 8 channels) to assign the QuadraVerb 2s digital outputs to. Going digital is the preferred method of recording if you use the QuadraVerb 2 with an ADAT. Since the DSP effects are created in the digital realm, why not let them remain there while being transferred to a tape medium? Also, if you connect the QuadraVerb 2s digital output to an Alesis AI-1, you can route the digital audio to other devices using either the AES/EBU or S/PDIF standards. This chapter is designed to illustrate the precise ways of connecting the QuadraVerb 2 to various digital audio peripherals, and how to manipulate the QuadraVerb 2s digital routings. It is divided into two parts. The first half of this chapter details the connections to various digital audio sources and destinations. The second half talks about the routing possibilities that are available on the QuadraVerb 2 for processing digital audio sources and transmitting to digital audio recorders.
Digital Clock Synchronization
Digital signals are self-clocking; they carry a word clock along with them. Usually the receiving unit automatically adjusts its sample clock to follow the rate of the incoming digital signal. When the receiving unit must synchronize to another clock--for example, an ADAT synchronized to SMPTE time code--a conflict may occur between the clocks that will result in audible "clicks" in the signal. For this reason, in more complex setups, the QuadraVerb 2 features a 48 kHz IN jack. This is to synchronize the sample clock of the QuadraVerb 2's analog-to-digital converter to the BRC or AI-2. If you're using the QuadraVerb 2 only to process signals that come via the optical input from the ADATs, this connection is not necessary because the optical clock coming in is already indirectly synchronized by the BRC. The 48 kHz connection IS necessary if the QuadraVerb 2 is the originator of the optical for the rest of the system, from its analog inputs, while the rest of the system is seeing the BRC as the master. A complete diagram of every single possible setup with every possible input would be needlessly complex. Just remember that there can only be one master clock. If the BRC is the master, the QuadraVerb 2 must be synchronized to its clock via the optical or the 48 kHz in. If you have a single ADAT with no BRC, the QuadraVerb 2 becomes the master clock source whenever the ADAT is set to DIGITAL IN and the QuadraVerb 2's Input Audio Source is set to ANALOG.

Re-initializing

To re-initialize the QuadraVerb 2, hold down both [PROGRAM] and [COMPARE] while turning on the power. This will reset all Global parameters to their default settings, and will initialize the edit buffer so that the current Program is set to its default settings (no Blocks/routings). However, none of the Programs in the User bank or the Preset bank are changed when re-initializing the unit this way.

Total Reset

A more drastic version of re-initializing the QuadraVerb 2 will erase all User Programs, as well as resetting all Global parameters. Hold down [PROGRAM], [COMPARE], and [<BLOCK] simultaneously while turning on the power.

Maintenance/Service

Cleaning
Disconnect the AC cord, then use a damp cloth to clean the QuadraVerb 2s metal and plastic surfaces. For heavy dirt, use a non-abrasive household cleaner such as Formula 409 or Fantastik. DO NOT SPRAY THE CLEANER DIRECTLY ONTO THE FRONT OF THE UNIT AS IT MAY DESTROY THE LUBRICANTS USED IN THE SWITCHES AND CONTROLS! Spray onto a cloth, then use cloth to clean the unit.

If you do not have the original packing, ship the QuadraVerb 2 in a sturdy carton, with shock-absorbing materials such as styrofoam pellets (the kind without CFCs) or bubble-pack surrounding the unit. Shipping damage caused by inadequate packing is not covered by the Alesis warranty. Tape a note to the top of the unit describing the problem, include your name and a phone number where Alesis can contact you if necessary, as well as instructions on where you want the product returned. Alesis will pay for standard one-way shipping back to you on any repair covered under the terms of this warranty. Next day service is available for a surcharge. Field repairs are not normally authorized during the warranty period, and repair attempts by unqualified personnel may invalidate the warranty. Service address for customers in the USA: Alesis Product Support 3630 Holdrege Avenue Los Angeles, CA 90016 Customers outside the USA: Contact your local Alesis dealer for warranty assistance. Do not return products to the factory unless you have been given specific instructions to do so. Note that the warranty is valid only in the country of origin.
