INSTALLATION INSTRUCTIONS, CONTINUED
COMMUNICATIONS INSTALLATION, Continued
Common terminal, and terminals 5 and 6 to the 600 ohm terminals of the remote
control transmitter unit.
Connect terminals 1 and 2 to the audio line pre-
viously connected to the AM modulator or SCA audio input.
Connect terminals 3
and 4 to AM transmitter audio input or SCA audio input.
AM SUBAUDIBLE RECEPTION--The AN Modulation Monitor or a high quality AM Re-
ceiver may be used to demodulate the AM signal to a composite audio signal upon
which the Bubaudible FSK carrier has been inserted.
The audio response of the
monitor or AM receiver must be flat to 20 Hz in order to properly pass the sub-
audible signal.
Some modern monitors have a subaudible output which roay be used
to feed the RMC-lSS.
FM SUBAUDIBLE RECEPTION--The SCA Generator 1n the transmitter should be
switched to Automatic Muting so that either the background music or the subaudible
tones will turn on the seA Generator.
The FM Subcarrier Monitor may be used as the recelver [or demodulating the
data required for remote metering.
Connect the 600 ohm audio output (0 DBM level)
of fue SeA monitor to 600 ohm terminals of the RMC-lSS unit.
A high quality crystal controlled SCA receiver may a1ao be used to recover the
metering data from the 67 KHz subcarrier at the studio.
Connect the 600 ohm
sub-
carrier audio output (0 DBM Level) of the receiver to 600 ohm terminals on the
RMC-15S.
COMMUNICATIONS ADJUSTMENT
INPUT AND OUTPUT CONTROLS
AND.
INDICATORS--Input and output controls are multi-
turn pots which may be adjusted with either a standard alignment tool, or suitaule
small screwdriver.
The output level indicators reflect output voltage with load.
A
no-load condition will cause it to read higher than normal, and a short or low-Z
COn-
dition will cause the output to read "LO" regardless of adjustment.
The input level
indication is derived from the incoming signal.
In the presence of acceptable,
characteristic control word patterns, the inpllt level indicator of the transmitter
