SUPERPHONE INPUT
Timer Restart
When the module is turned ON, the console’s digital timer can be
programmed to automatically reset to zero and begin counting up.
SW1 position 7 activates timer restart when the phone module’s
ON/START switch is pressed*
Tallies
Turning the module ON can activate a remote tally indicator. There are two
tally control lines: on-air and tally 2.
SW1 position 6 activates the on-air tally control line
(along with control room mute)
SW1 position 4 activates tally 2
Cue Dropout
CUE (i.e., caller CUE buttons 1 & 2) can be made to turn off when the
module’s ON/START switch is pressed. This is the factory default setting.
SW1 position 1 activates cue dropout
External Input
A mono input can be activated to feed the module’s outputs.
SW1 position 3 activates the external input (default is off)
Gain Trimpots
There are eight PCB-mounted trimpots, located on the SP-75 PCB. They
are used as follows:
CR1 - sets Callers 1 In port input gain
CR2 - sets Callers 2 In port input gain
CR3 - sets the Ext In port input gain
CR6 – sets the module’s “composite” output level
CR7 – sets the module’s “composite minus callers” (“mics out”)
output level
CR8 – sets the module’s “callers only” output level
CR9 – sets the module’s output level to Hybrid 1
CR10 – sets the module’s output level to Hybrid 2
The first two trimpots are accessible through holes in the module faceplate.
