AGC RELEASE (CONF.AGC.REL) – read/write
With this parameter, tune in dB/s the AGC correction speed to a volume decrease. A low setting is
recommended to slowly increase the gain in case of low audio level and maintain maximum audio fidelity.
Set this parameter to 1dB/s or lower for more transparency; 2 or 3 dB/s will give a slightly more processed
result. Default value: 1 dB/s
From 0 to 6 dB/s
AGC GATE THRESHOLD (CONF.AGC.THR) – read/write
This threshold will freeze the AGC operation when the audio level is below the user-set limit. This function
limits floor noise and prevents unwanted AGC processing on the audio. Default value: -20 dB
From -100 to 0 dB
LIMITER STATE (CONF.STATE.LIMIT) – read/write
This parameter enables or disables the FM Limiter stage. Default: off.
Off/On
LIMITER DRIVE (CONF.DRIVE.LIMIT) – read/write
With this parameter, load more or less the FM limiter input. CAUTION: Always be aware that increasing the
FM limiter drive may lead to noticeable distortion. Setting the limiter drive at 0 dB is recommended to use the
FM Limiter as a protection stage against over-modulation.
From 0 to 1 dB
MPX POWER LIMITER STATE (CONF.STATE.MPXPWR) – read/write
This parameter enables or disables the MPX Power Limiter processing stage. Do not activate the MPX
power reduction if no standard requires you to do it; it could have a negative impact on the sought after
sound level. Default: off.
Off/On
MPX POWER LIMITER LEVEL (CONF.DEV.MPXPWR) – read/write
Set the maximum authorized MPX Power. Default value: 3 dB.
From -3 to -10 dB
5.4.12. RDS Menu
With the Basic RDS option, configure up to 2 DSNs each with a main PSN. Among other things, the DSNs
allow fast and easy changing of the encoder settings remotely.
Note: the RDS is enabled in the RDS/SCA ENCODER menu.
These parameters are available as RDS serial commands (see section 6.2.7).
CURRENT MAIN (RDS.DSN)
This parameter indicates the current DSN number.
