PRESET NAME
(CONF.SP.PRESET.NAME)

CLIPPER STATE
(CONF.STATE.CLIP)
–

Off/On
CLIPPER DEVIATION
(CONF.DEV.CLIP)
–
read/write
With this parameter, set the MPX hard clipper to prevent any possibility of overmodulation on the modulator itself.
This process is carried out digitally right before the RF generation, and is therefore enabled on all the inputs. If the
deviation is greater than the configured value (in kHz), the MPX hard clipper is automatically enabled. Unlike FM
limiters/clippers used in audio processing, this clipper cannot be used continuously for it generates a noticeable audio
distortion. It is therefore best to set it at the maximum authorized deviation, plus a few kHz to ensure additional
security, for instance, set it at 90 kHz for a 75 kHz nominal deviation.
From 0 to 200 kHz
MPX POWER STATUS
(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
