Mother Board
This card receives input signals (LEFT, RIGHT, RDS and SCA), for example from
a audio mixer or a satellite receiver. These signals are normalized (amplified or
attenuated) for the nominal levels, filtered (15KHz filters are included for the L and
R channels) and pre-emphasized.
Then, the signal is processed by a digital circuit and then is sent to MPX output.
Here, this signal is mixed, if present, with RDS or SCA input.
On the board are presents same jumpers that allow to select the input impedance
(10KOhm, 600Ohm, 50Ohm), to increase the SCA gain, to select the pre-emphasis
value (25µS, 50µS, 75µS or without) and than to insert the clipper circuit.
See the figure below for the jumper setting:
