Multi channel DSP Amplifier

 

 

 

When the multi channel DSP amplifier is connected to the DSP matrix mixer it is

 

recommended to connect via either Amp Link connectors or the phoenix terminal inputs. The

 

amplifier also has XLR/TRS combo inputs in case it will be used without the DSP matrix mixer.

Loudspeaker

– 4 x loudspeaker outputs via Phoenix terminal:

 

 

 

 

 

outputs

– Connections: 100V, 70V, 8Ohm, 4Ohm and 0V.

Fan grille

Exhaust air vent for amplifier cooling. Do not obstruct!

 

 

 

 

 

 

 

 

5

XLR/TRS combo

– 4 x XLR 3-pin balanced line level audio input (1-4). Mainly used when the

 

 

inputs/loop out

amplifier is not connected to the DSP matrix mixer (standalone amplifier):

 

 

 

– The inputs/outputs are internally, in parallel, connected with the associated

 

 

Phoenix input connectors, for use as either input or loopthrough output.

 

 

– XLR 3-pin number connection: 1 = ground, 2 = + signal, 3 = - signal.

 

 

 

 

 

 

 

 

6

Phoenix inputs/

– 4 x 3-pole Phoenix connector audio input (1-4):

 

 

 

 

 

loop out

– The inputs/outputs are internally, in parallel, connected with associated

 

 

XLR/TRS combo input/loop out connectors for use as either input or output.

 

 

– Left to right pin configuration: 1 = + signal, 2 = - signal, 3 = ground.

 

 

 

 

7

Amp Link

– 1 x RJ45 connector. Connects 4 sequential channels of the amplifier to the DSP

 

connection

matrix mixer. Processor output channels 1-4 or 5-8.

 

 

 

 

 

 

– For best practice Bosch recommends use with STP CAT5 (e) cable.

 

 

 

– Maximum recommended cable distance 5m.

Auto Standby

– 4pole Phoenix connector to attach a Bosch motion sensor, to activate auto

 

Mode

standby.

 

 

 

 

 

 

connections

– The amplifier also can supply 12V DC power for a motion detector.

 

 

 

– Left to right pin configuration: 1= +12V DC, 2 = 0V DC, 3= Sensor +, 4 =

 

 

Sensor -.

 

 

 

 

 

 

 

 

 

 

 

9

Override input

4-pin pluggable screw socket/connector with ESD protection:

 

 

 

 

 

– Logic override input (+, - and shield balanced input).
