SUPERPHONE INPUT
Mutes
When the SPD-70 phone channel ON switch is pressed, it can activate
console mute functions. Jumpers J21 and J22, mounted on the PR-70 PCB,
determines which of the console’s two mute lines will be activated:
J21 mutes the control room when the phone module is ON*
J22 mutes studio when the phone module is ON
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.
J24 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
three tally control lines: on-air, tally 2 and tally 3. Jumpers J25-J27 program
these functions:
J25 activates the on-air tally control line
J26 activates tally 2
J27 activates tally 3
Cue Dropout
Jumper J28 will cause CUE (i.e., caller set-up buttons 1 & 2) to turn off
when the module’s ON/START switch is pressed. This is the factory default
setting.
Gain Trimpots
There are seven PCB-mounted trimpots, located on the SPIO-70 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 module’s output level to Hybrid 1
CR4 – sets the module’s output level to Hybrid 2
CR5 – sets the module’s “callers only” output level
CR6 – sets the module’s “composite minus callers” (“talent”)
output level
CR7 – sets the module’s “composite” output level
Remote tallies are
hooked-up to the console
at the Control Room mod-
ule (CRD-70)
*factory default setting
*factory default setting
Factory default settings for
these trimpots is UNITY
GAIN.
