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 channel for that particular
location is activated. The same MUTE control lines can also activate
TALLY ports at the console’s control room monitor (CRM-80) and
studio monitor (STM-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 [L1 thru L4] may be programmed separately. See
Technical Drawings “SI-80” load sheet (page 44, lower right) and
schematic (page 42, C-3). The input mute programming dipswitches
are:
Line 1 – Dipswitch “SW19”
Line 2 – Dipswitch “SW20”
Line 3 – Dipswitch “SW21”
Line 4 – Dipswitch “SW22”
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 “SW18”. See Technical
Drawings “SI-84/88” load sheetS (page 27/36, lower right) and
schematicS (page 25/34, C-2).
Mix Minus
The input module’s summed mix-minus assign signal may be
programmed 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 Draw-
ings “FPI-80” load sheet (page 41, left center) and schematic (page 38,
dead center).
