Front Panel Controls 
Input Gain — Used to adjust the gain of AUDIO IN. For more about using 
Mopho to process external audio, see page 11. For low-level sources (like 
guitars), I
NPUT GAIN should be turned up. For line-level sources, it will usually 
be turned down. Turning it down does not turn it off, it just decreases the gain. 
External Input Volume (see Mixer Parameters on page 17) controls the amount 
of signal that gets mixed into the filter and must be turned up for any audio—
external or feedback—to be heard. 
Note: The factory programs use a naming convention where “FB” 
indicates a program is designed to take advantage of the feedback 
capability. When nothing is plugged into the Audio In jack, the left 
Audio Output is normalled to the input. This provides a feedback path 
that will create some unique, wild sounds. I
NPUT GAIN is not a 
programmable control, so its position will have an effect on those 
programs. For most FB sounds, the
 INPUT GAIN should be set to 
minimum, and will get out of control (often nicely!) when turned up. 
Program — Use PROGRAM to change and scroll through the programs. Also 
used to select parameters in Global mode. 
Program Mode — Mopho has three modes of operation: program, edit, and 
global. When in program mode, the display shows the name, number, and bank 
of the current program. Editing any of the parameters puts Mopho into edit
