Chapter 2 – Connections
• 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.
• 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 MidiVerb 4 is placed between the source and the
mixer/amplifier. Although the source may be mono, both the [LEFT/CH.1] and
[RIGHT/CH.2] 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 MidiVerb 4. If using the effect sends of a mixer, you have the
advantage of sending any of the mixer's input channels to the MidiVerb 4's input(s),
and have control over the level of each channel being sent.
These applications are outlined and illustrated in detail on the following pages.

Input Jack Wiring

The MidiVerb 4's [LEFT/CH.1] INPUT jack is normalled to the [RIGHT/CH.2] INPUT.
This means that if you only connect a single mono cable to the [LEFT/CH.1] INPUT
jack, it will also be routed to the [RIGHT/CH.2] INPUT. However, if anything is
connected to the [RIGHT/CH.2] INPUT jack, this normalized connection will be
broken; therefore the [LEFT/CH.1] INPUT jack feeds only the [LEFT/CH.1] INPUT,
and the [RIGHT/CH.2] INPUT jack feeds only the [RIGHT/CH.2] INPUT. Also, the
[RIGHT/CH.2] INPUT jack is NOT normalled to the [LEFT/CH.1] INPUT.
