FM VERSION DESCRIPTION ENG

11.6AUXILIARY INPUTS

The Aux inputs allow the Mpx, SCA, RDS injection from external coders. The resultant signal (f.i. external RDS+ self-generated MPX) is available on the Output connector.

Remarks:

When using an external RDS encoder, the internal RDS one must be disabled.

The level of the injected signal may be adjusted by means of the trimmer next to the corresponding BNC connector (no software control is provided for this purpose). This trimmer is factory preset for a gain of 0 dB.

Suggested RDS injection level is -31.5 dBm (≈ 60mVpp / 2.0 kHz deviation) in relation to an MPX output of 0 dBm (2.2 Vpp, 0.776 Vrms).

AUX Input impedance is 10 KOhm.

11.7ANALOG AUDIO INPUT (Female XLR)

Balanced XLR-type connectors are used for input analog audio.

The stereo analog inputs are designed for standard 0 dBu balanced signals. Input level setting (Sensibility) is done using the software parameter settings (see par. 12.1).

XLR pinout:

Pin 1	Gnd
Pin 2	Signal
Pin 3	Return

In case of unbalanced connections, please connect the cold pole (Pin 3) to the ground (Pin 1).

Factory preset input impedance is 10 kOhm. This impedance may also be set to 600Ohm by moving the two internal jumpers on the INPUT board (see Chapter 19 - hardware settings).
