Audio generator parameters
These parameters are available as:
Front panel
AUDIO GENE menu
see section 6.3.9
Serial commands

see section 7.2.6
Engi PC application
Audio Input page
see section 8.2.2
Embedded web site
Transmitter/Input Source/Generator page

The audio generator is a multiplex channel and is therefore not affected by the stereo encoder parameters.
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
