MODULE FUNCTIONS - The Module Port accepts a stan-
dard audio Module. When a Module is utilized several func-
tions can be activated by the Jumpers and Switch provided
for this Input.
VOX SEND - The SW221 Jumpers Set activates the VOX 1
- VOX 2 SEND or both. When a Signal is present at the
Module Output (Contact 4) then the VOX BUSS selected will
be active.
MUTE RECEIVE - The SW222 Jumpers Set activates the
MUTE 1 - MUTE 2 RECEIVE or both. When a Signal is pres-
ent at the MUTE BUSS 1 or MUTE BUSS 2 the MODULE
will be MUTED accordingly.
INPUT SOURCE - The SW209 Switch selectes the Input
Source for the Module either AUX 1 or AUX 2. The Signal
present at either Input will be sent to the MODULE INPUT
(Contact 5).
By selecting the proper Setting several functions can be
derived from the Module.
