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.

Description
AC mains power switch.
AC mains input socket.
– 4 x loudspeaker outputs via Phoenix terminal:
– Connections: 100V, 70V, 8Ohm, 4Ohm and 0V.
Exhaust air vent for amplifier cooling. Do not obstruct!
– 4 x XLR 3-pin balanced line level audio input (1-4). Mainly used when the
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 loop‑through output.
– XLR 3-pin number connection: 1 = ground, 2 = + signal, 3 = - signal.
– 4 x 3-pole Phoenix connector audio input (1-4):
– 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.
– 1 x RJ45 connector. Connects 4 sequential channels of the amplifier to the DSP
matrix mixer. Processor output channels 1-4 or 5-8.
– For best practice Bosch recommends use with STP CAT‑5 (e) cable.
– Maximum recommended cable distance 5m.
– 4‑pole Phoenix connector to attach a Bosch motion sensor, to activate auto
standby.
– 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 -.
– 4-pin pluggable screw socket/connector with ESD protection:
– Logic override input (+, - and shield balanced input).
