AUDIO PROCESSOR
COMP PGM LVL (R28) Composite program level adjustment. Sets the transmitter deviation of
the composite signal. Normal input is 3.5 V
p-p
. The normal deviation of
the transmitter is
±
50 kHz.
MONO PGM LVL (R199) Monaural program level adjustment. Sets the transmitter deviation of
the mono signal. Normal input is +10 dBm. The normal deviation of
the transmitter is ±40 kHz.
DIG PGM LVL (R200) Digital modulation program level adjustment. Sets the transmitter
deviation of the digital signal in DSP6000 applications. Consult the
DSP6000 manual for further information.
MUX1 LVL (R29) MUX (ch. 1) level adjustment. Sets the transmitter deviation for the
MUX (ch. 1) deviation. The normal input is 1.5 V
p-p
at 110 kHz. Main
carrier deviation normally is ±5 kHz.
MUX2 LVL (R40) MUX (ch. 2) level adjustment. Sets the transmitter deviation for the
MUX (ch. 2) input. The normal input is 1.5 V
p-p
at 185kHz. Main
carrier deviation normally is ±7.5 kHz.
PHASE SELECT (E2) Jumper used to select the phase of the modulation. Position A is in-
phase and position B is 180 degrees out-of-phase.
