SAMPLING
(INPUT.LINE1.GET_SAMPLING)
–
read
This parameter reads the sampling rate in Hz.
From 0 to 200000 Hz
NO SYNC
(INPUT.LINE2.NO.SYNC)
–
read/write
With this parameter, set whether the loss of synchronization on the AES input should lead to a switch of channel. On
the website, it is the “Check sync” parameter of the Transmitter/Input Select/Silence Detector page.
Off/On
5.10.
MPX parameters
MPX1 / MPX2 / MPX3 / MPX4
MPX3 and MPX4 are available when line 2 is set as a digital MPX input (this operation must be done with serial
command (SYS.DIGMPX) or on the Product configuration page of the web site).
These parameters are available as:
Front panel
MPX Ana / MPX Digi menus
see sections 6.3.9 and
6.3.10
Serial commands
INPUT.MPX1 / INPUT.MPX2
see sections 7.2.6
Embedded web site
Transmitter/Input Source/MPX page
see section 8.4.5
PRESENCE
(INPUT.MPXn.PRESENCE)
–
read only
This parameter gives the composition of the signal on the MPXn input.
MO (mono), MO+R (mono+RDS), MO+R+S (mono+RDS+SCA), ST (stereo), ST+R (RDS) or ST+R+S
(RDS+SCA)
LEVEL
(INPUT.MPXn.LEVEL)
–
read/write
This parameter is the max audio peak in dBu that can come from the transmitter on the MPX input. For example, if the
audio peak from the source is +6 dBu, this parameter must be set to +6 dBu for optimal operation. If you do not know
the audio source level, you may use an audio analyzer or display first level measurements on the front panel to read
the MPXn LEVEL. Be aware that if the level is poorly set the deviation may become too low or too high. This level is
also called nominal level, i.e. the level producing the deviation as set in the Modulation menu.
From -18 dBu to +18 dBu
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
