MPX Output
The MPX Output Setup page,
, allows the user to configure the MPX (FM Multiplex) signal,
including the percentages for Pilot, RDS, and output amplitude. There is no adjustment for the L+R or L-
R components, as these will be set to maximum FCC allowed values based upon the other selections.
The default MPX amplitude is 1.25V
rms
, but is adjustable in 1mV increments. This page also allows for
selection of user settings or pass-through of received RDS data, and will hide non-applicable settings.
The RFBA currently supports RDS AF (Alternate Frequency) encoding using “Method A” of FM
frequencies only, and is limited to a maximum of 15 frequencies. A pass-through option is not available
for RDS AF encoding.
