Input Module Logic Programming
Mute/Tally
The console has four separate MUTE control lines; each input module
may be programmed to activate any of these via its channel ON switch. The
MUTE control lines are used to shut off control room and studio monitor
speakers whenever the microphone for that particular location is activated.
The same MUTE control lines can also activate TALLY ports at the
console’s control room monitor (CR-80) and studio monitor (SC-80)
modules (see pages 5-6 and 6-5).
Input module programming is accomplished by PCB-mounted
dipswitches located on the main module PCB. Note each of the channel’s
inputs [M1/2, L1/2] may be programmed separately. See Technical
Drawings “MI-80” load sheet (page 15, lower right) and schematic (page
13, D-3). The input mute programming dipswitches are:
Mic 1 – Dipswitch “SW13”
Mic 2 – Dipswitch “SW14”
Line 1 – Dipswitch “SW15”
Line 2 – Dipswitch “SW16”
NOTE on those input modules with an associated preselector panel,
each preselector input can also be programmed to mute separately. The
eight associated preselector panel dipswitches are “SW1” through “SW8”
on the preselector panel PCB. See Technical Drawings “SB-80” load sheet
(page 127, center) and schematic (page 126, B-3).
Timer Restart
Input modules may be programmed to automatically reset the console’s
digital timer to zero and start it counting up whenever the channel On
switch is pressed (this is the default setting). This is accomplished by PCB-
mounted slide switch “SW12”. See Technical Drawings “MI-80” load
sheet (page 15, lower right) and schematic (page 13, C-1).
Mix Minus
The input module’s summed mix-minus assign signal may be pro-
grammed pre or post fader via a PCB-mounted slide switch (“SW14”) on
the module’s fader panel main PCB. See Technical Drawings “FPI-80”
load sheet (page 41, lower left) and schematic (page 38, C-5). The default
setting is “post”.
The input module’s summed mix-minus assign signal may also be
programmed to follow the channel ON switch via a programming jumper
(“J3”) on the module’s fader panel main PCB (this is the default setting).
If jumper “J4” is installed instead, then mix-minus will follow the
console’s Mute Group control lines as well. See Technical Drawings “FPI-
80” load sheet (page 41, left center) and schematic (page 38, dead center).
