When connecting audio cables and/or turning power on and off, make sure that all devices in
your system are turned off and the volume controls are turned down.
The MidiVerb 4 has two 1/4" unbalanced inputs and two 1/4" unbalanced outputs.
These provide three different (analog) audio hookup options:
• Mono. Connect a mono cord to the [LEFT/CH.1] INPUT of the MidiVerb 4 from a
mono source, and another mono cord from the [LEFT/CH.1] output of the
MidiVerb 4 to an amplification system or mixer input.
• Mono In, Stereo Out. While still using a mono input, you could connect two
mono cords to the [LEFT/CH.1] and [RIGHT/CH.2] outputs of the MidiVerb 4 to
a stereo amplification system or two mixer inputs.
• Dual Mono. Connect two mono cords to the [LEFT/CH.1] and [RIGHT/CH.2]
inputs of the MidiVerb 4 from two mono sources , and two other mono cords
from the [LEFT/CH.1] and [RIGHT/CH.2] outputs of the MidiVerb 4 to a stereo
amplification system or two mixer inputs. This hookup allows discrete
processing of the two channels, since blocks can be dedicated to a single channel.
• Stereo. Connect two mono cords to the [LEFT/CH.1] and [RIGHT/CH.2] INPUTS
of the MidiVerb 4 from a stereo source , and two other mono cords from the
[LEFT/CH.1] and [RIGHT/CH.2] OUTPUTS of the MidiVerb 4 to a stereo
amplification system or two mixer inputs.
