Alesis MidiVerb 4 Reference Manual - They Remained Silent

Connections – Chapter 2
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.
Using Main Outputs
When you want to effect everything on the mixer, you can connect the MidiVerb 4
between the mixer’s outputs and the amplifier’s or tape machine’s inputs. This is
done by using two 1/4" mono cables to connect the Left and Right Main Outputs of
the mixing console to the [LEFT/CH.1] and [RIGHT/CH.2] inputs of the MidiVerb 4.
The [LEFT/CH.1] and [RIGHT/CH.2] outputs of the MidiVerb 4 are then connected to
a stereo amplifier, or two input channels of another mixing console (for sub-mixing
applications).
