Typical Applications; Interfacing Directly With Instruments - Alesis QuadraVerb 2 Setting Up

Chapter 1 - Setting Up
quality cables cost more, they do make a difference. Route cables to the QuadraVerb
2 correctly by observing the following precautions:
• Do not bundle audio cables with AC power cords.
• Avoid running audio cables near sources of electromagnetic interference such as
transformers, monitors, computers, etc.
• Do not place cables where they can be stepped on. Stepping on a cable may not
cause immediate damage, but it can compress the insulation between the center
conductor and shield (degrading performance) or reduce the cable's reliability.
• Avoid twisting the cable or having it make sharp, right angle turns.
• Never unplug a cable by pulling on the wire itself. Always unplug by firmly
grasping the body of the plug and pulling directly outward.
• Although Alesis does not endorse any specific product, chemicals such as
Tweek and Cramolin, when applied to electrical connectors, are claimed to
improve the electrical contact between connectors.

Typical Applications

The analog audio inputs and outputs are typically used in one of three ways:
• from one or two effect/aux send outputs of a mixer, and out to the effect return
inputs of the mixer; or,
• from a line-level instrument (like a guitar or keyboard with either a mono or stereo
output), and out to an amplifier or mixer input; or,
• from the stereo buss outputs of a mixer to a mix-down tape machine or amplifier.
When used with a mono source, the QuadraVerb is placed between the source and
the mixer/amplifier. Although the source may be mono, both the [LEFT] and [RIGHT]
outputs can be connected to the inputs of a mixer/amplifier if stereo processing
effects are desired. Alternatively, you could use the INSERTS on your mixer to "patch
in" only the left or right channel of the QuadraVerb 2. If using the effect sends of a
mixer, you have the advantage of sending any of the mixer's input channels to the
QuadraVerb 2's input(s), and have control over the level of each channel being sent.
There are other combinations of input and outputs possible when you begin using
the Alesis optical digital input and output. See the "Alesis Optical" section later in this
chapter. For more information on interfacing with other digital audio equipment, see
chapter 7.

Interfacing Directly with Instruments

When connecting audio cables and/or turning power on and off, make sure that all
J
devices in your system are turned off and the volume controls are turned down.
The QuadraVerb 2 has two 1/4" balanced inputs and two 1/4" balanced outputs.
These provide three different (analog) audio hookup options:
• Mono. Connect a cable to the [R] INPUT of the QuadraVerb 2 from a mono
source, and another cable from the [R] OUTPUT of the QuadraVerb 2 to an
amplification system or mixer input.
