PREACC
(INPUT.LINE1.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
5.6.
Line 2 (AES) parameters
These parameters are available as:
Front panel
LINE 2 menu
see section 6.3.7
Serial commands
INPUT.LINE2
see section 7.2.6
Engi PC application
Audio Input page
see section 8.2.2
Embedded web site
Transmitter/Input Source/Line2 page
see section 9.4.5
They are identical to LINE1 parameters, except for the level, and the Sampling and No Sync parameters which
only applies to an AES stream.
LEVEL
(INPUT.LINE2.LEVEL) – read/write
This parameter is the max audio peak in dBu that can come from the transmitter on the LINE2 input. For example, if
the audio peak from the source is -4 dBFS, this parameter must be set to -4 dBFS 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 LINE2 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 -20 dBFS to 0 dBFS
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
5.7.
MPX parameters
MPX1 or MPX2
These parameters are available as:
Front panel
MPX IN menu

Serial commands
INPUT.MPX1 / INPUT.MPX2
see sections 7.2.6
Engi PC application
