To Turn the Module ON & OFF from a Remote Location
ON — Activates the module’s channel ON switch. Provide a
momentary closure between Pin 6 (On) and Digital Ground (Pins 7, 8
or 12). This will latch the module ON. (User-supplied momentary
contact switch required.)
OFF — Activates the module’s channel OFF switch. Provide a
momentary closure between Pin 5 (Off) and Digital Ground (Pins 7, 8
or 12). This will latch the module OFF. (User-supplied momentary
contact switch required.)
COUGH — Temporarily Mutes the module. Provide a closure
between Pin 1 (Cough) and Digital Ground (Pins 7, 8 or 12). This will
turn the module OFF. Note this is a non-latching mode; the module will
turn ON again as soon as the closure stops. (User-supplied momentary
contact switch required.)
Talkback to Control Room
If an IND-70 module is being used for a studio microphone, this
connection allows talkback from that studio to the console operator.
Provide a closure between Pin 2 (TB to CR) and Digital Ground (Pins
7, 8 or 12). This will cause two things to happen: (1) the module’s pre
fader signal is sent to the console’s Cue bus, where it may be heard by
the console operator, and (2) the module’s Cough function is activated,
muting the module’s post fader signal and preventing the TB signal
from going out over other assigned busses (i.e., “live”). This non-
latching condition continues until the closure is released. (Requires
user-supplied momentary action TALKBACK switch at the studio
microphone location.)
On Tally
Lets the module’s channel ON switch control an on-air light or other
“microphone on” indicator at a remote location. This control function
provides a continuous closure (open collector) between Pin 4 (On
Tally) and Digital Ground (Pins 7, 8 or 12) whenever the module is ON.
