SIDECHAIN MODE (PREFERRED)

Attach a BNC 'T' adapter to the composite/MPX output of the stereo generator as shown in

Figure below. Connect one side of the 'T' directly to a wideband (composite/ MPX) input of the

FM exciter and the other side to the PILOT OR MPX INPUT of the SmartGen Micro. (This is only

a bridging 'sync' connection when the circuit board has been jumpered for sidechain operation and

does not affect the composite/MPX signal.)

If the stereo generator has a dedicated 19kHz TTL-level output designated for RDS encoder

sync, you may connect this to the encoder PILOT OR MPX INPUT. We do not recommend this,

as a dedicated 19kHz sync output may not have the proper phase relationship with the stereo pilot.

Cable the RDS OR MPX OUTPUT of the encoder to a second wideband (subcarrier) input of

the FM exciter.
