THE MPX GENERATOR
15.1 MPX SECTION
The MPX section contains controls for the two multiplex outputs (MPX OUT-1 and MPX OUT-2)
15.1.1 MPX Output Level
This section contains two individual controls for the two
composite outputs. This way, the equipment that requires
different power levels can be handled individually, so that they
can be adjusted as needed. Level adjustable from -6.0 dBu to
+12.0 dBu in 0.1 dBu-steps.
15.1.2 Pilot Control
Pilot Level : the default setting is -20 dB with respect to the
overall composite MPX stereo signal. Use the horizontal bar
to change this level within a range of -14.0 dB to - 25.5 dB in
0.1 dB-steps. The Stereo Pilot signal can be disabled using
the relative controls on the MPX Output Mode units.
Pilot phase: this can be adjusted within a range of - 12.0 to
+ 12.0 degrees (Deg) in 1- degree steps. The phase
selection function is used to adjust the phase relationship
between the pilot and the 19 kHz/38 kHz modulator. This
can be used to correct incoherence between different
transmitters.
15.1.3 Output Source Selection
This selector switch allows you to set which audio signals to
send to the MPX Stereo Generator unit. The audio signals
can be sent directly to the sound processor input, in which
case the audio processor is bypassed. In this position, the
pre-emphasis is also removed.
In the "Processed" position, audio material (processed
according to the parameters set in the "Audio" section) is sent
to the Audio Processor instead of the MPX Stereo Generator.
This is generally the standard operation position.
If "Internal Generator" is selected for the MPX Stereo Generator, the audio signals are sent to the internal tone
generator, as shown in Audio Control -> Menu -> Internal Generator. There are various sinusoidal frequencies and
various operation levels. This generator is extremely useful during an audio chain alignment stage.
