6. ODEL mtem ALSCB 3 2 MPX MPX is an abbreviation for Multiplex signal Multiplex is the name commonly used to describe the encoding of stereo audio signal band developed by Zenith GE and used for standard stereo FM broadcasting There are two options for MPX output First the MPX output can be connected directly to the MPX input with RCA to RCA cable included This is the default condition Second is when you want to include an external encoder RDS in the system The exact configuration will depend on the RDS encoder used but the most basic level MPX output connects to the RDS encoder and the RDS encoder output is connected to the MPX input 3 3 INPUT Audio 10dBu a 20dBu The connector is RCA phono type of unbalanced with a Hi Z input of 10K ohms The typical input level is 4 dBu nominal Any input level to 20 dBu can be applied Any level higher than the 6 dBu will lead to a constant level output this is the limiter threshold level Any reduction in input level below 6 dB will have a linear reduction in the output See fig 1 C 3 4 INPUT MPX The MPX input also accepts simple mono audio signals and RDS Radio Data System or a combination of these The connector is RCA phono type unbalanced with a Hi Z input of 10k ohms You must use high quality shielded cable to connect other equipment The excitor is factory set to give 75 kHz deviation FM maximum allowed at 88 0 MHz to 4 dBu input To comply
