Q20 Reference Manual 9
Interfacing Directly with Instruments
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 Q20 has two balanced inputs and two balanced outputs. These provide three
different (analog) audio hookup options:
¥ Mono. Connect a cable to the [L] INPUT of the Q20 from a mono source, and
another cable from the [L] OUTPUT of the Q20 to an amplification system or
mixer input.
¥ Mono In, Stereo Out. While still using a mono input, you could connect two cables
to the [L] and [R] OUTPUTS of the Q20 to a stereo amplification system or two
mixer inputs.

¥ Dual Mono or Stereo Source. The Q20 may be used with two different instruments
simultaneously, or with a stereo instrument. The hookup is the same; the
difference is in the routing used within a program. A program may process the
two inputs discretely, using blocks dedicated to a single channel (for example, a
delay for a guitar and a gated reverb for a bass), or process them in stereo (for
example, with the left and right outputs of a keyboard routed through two reverb
blocks). Connect two cables to the [L] and [R] INPUTS of the Q20 from two mono
sources or from the stereo output of the instrument, then connect two other cables
from the [L] and [R] OUTPUTS of the Q20 to a stereo amplification system or two
mixer inputs.

Note: In most cases when plugging an instrument directly into the Q20 , youÕll use
Programs which route the "dry" signal at the input(s) directly to the output(s),
where it will be mixed together with the effected signal to achieve the proper
wet/dry mix at the Q20's outputs. If the program doesn't include this routing, you
will only hear the effected signal by itself. Therefore, it may be necessary to edit
such programs to add these "dry" routes when using the Q20 directly with an
instrument. (The Factory Preset programs usually include these routes.)
