DRIVE
(INPUT.MPXn.DRIVE) – read/write
With this parameter, you can slightly compensate the input audio level. It directly affects the final deviation. A
negative value decreases the deviation; a positive value can increase the deviation and/or cause the MPX
hard clipper to be used (if enabled) which in turn may lead to audio distortion. We recommend you leave it at
0 dB.
From -6 dB to +6 dB
RMS
(INPUT.MPXn.RMS) – read only
This parameter indicates the average value of the transmitted signal’s excursion in kHz.
From -150 to +150 kHz
PEAK
(INPUT.MPXn.PEAK) – read only
This parameter indicates the peak value of the transmitted signal’s excursion in kHz.
From -150 to +150 kHz
5.4.6. Player
menu
These parameters are available as INPUT.PLAYER serial commands (see section 6.2.5).
They are identical to LINE2 menu parameters.
5.4.7. Audio
Gene
menu
The audio generator is a multiplex channel and is therefore not affected by the stereo encoder parameters.
These parameters are available as INPUT.AUDIOGEN serial commands (see section 6.2.5).
STATE
(INPUT.AUDIOGEN.STATE) – read/write
With this parameter, set the type of MPX signal generated by the internal generator.
OFF, PILOT, L, R, L+R (mono) or L-R (stereo)
PREAC
(INPUT.AUDIOGEN.PREAC) – read/write
With this parameter, set the pre-emphasis. Select 0 µs is the audio signal is pre-emphasized before getting to
the transmitter. Otherwise, select according to the country: 50 µs in Europe, 75 µs in the USA.
0, 50 or 75 µs
LEVEL
(INPUT.AUDIOGEN.LEVEL) – read/write
With this parameter, set the internal generator audio level.
From -100.00 to 12.00 dBFS
