DEV AUDIO (CONF.DEV.AUDIO) – read/write
With this parameter, set the maximum audio deviation in kHz generated when the audio source is at the
nominal level (the nominal level is set with the LEVEL parameter of the menus: LINE1, LINE2, MPX1 or
MPX2). The audio deviation is set automatically when the MPX deviation parameter is set; however, it is
possible to set the audio deviation rather than the MPX deviation. Increasing or decreasing the audio
deviation affects the total deviation and thus automatically adjusts the MPX deviation. Make sure to avoid
over-modulation.
From 0 to 150.00 kHz
DEV PILOT (CONF.DEV.PILOT) – read/write
With this parameter, set the 19 kHz pilot deviation. For countries modulating at 75 kHz, the pilot deviation
should be 10% of the total deviation, i.e. 7.5 kHz without RDS or 7.1 kHz if RDS is used.
From 0 to 25.5 kHz
DEV RDS (CONF.DEV.RDS) – read/write
With this parameter, set the RDS sub-carrier deviation. The most widely used value is 4 kHz.
From 0 to 25.5 kHz
DEV SCA (CONF.DEV.SCA) – read/write
With this parameter, set the SCA deviation (auxiliary sub-carrier other than RDS), as needed.
From 0 to 25.5 kHz
Interaction between the various components according to the input type:
In all cases described below, the transmitter configuration is as follows:
Audio = 67.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz.
In the case of audio inputs (analog or AES), the set MPX represents the total of audio, pilot and RDS. If the
RDS is disabled, the audio is automatically adjusted with +4 kHz.
Ex 1: set MPX = 75 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz.
If the RDS is enabled:
If the RDS is disabled:
In the case of MPX inputs, if the RDS is disabled, the audio cannot be adjusted.

Audio = 63.5 kHz
Pilot = 7.5 kHz
RDS = 4.0 kHz
Audio = 63.5 + 4 = 67.5 kHz
Pilot = 7.5 kHz
