Connect

For the connection a 8-pin plug connector is used. To avoid

false connetion with the plugs between X1 and X2, the plugs

are encoded.

The power supply need a direct current voltage of

24 Volt. Connect the Ground to the GND (pin 03,04) the posi-

tive pole +24V DC (pin 01,02). Two pins are available for loop

trough.

You can use loudspeakers with an impedance of 4 Ohms or

8 Ohms at the audio outputs. The loudspeakers can be oper-

ated in stereo and also bridged mode (look at the terminal

assignment in the circuit layout). For operating the bridged

mode it is required to use loudspeakers with an impedance of

8 Ohms and the switch (5) has to be allocated on bridge.

The audio input signal could connected symetrical or unsy-

metrical. Use (-X2) pin 11, 13 In left and pin 14,16 In right for

symetrical operation (symetrical input is appropriate for long

cable distances up to 300m).

For unsymetrical input use the additional pin 12 respectively

15 for the shield (AGND).

At the micro IN (Pin 9,10) is a phantom power of 12V provided

for active electret microphones with integrated with a sensi-

tivity of 1V.

For an additional ground is a 6,4mm blade receptacle connec-

tor equipped (-X3).
