6.3	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.

Number	Item	Description
1	Power on/off	AC mains power switch.
2	Mains inlet	AC mains input socket.
3	Loudspeaker	– 4 x loudspeaker outputs via Phoenix terminal:
	outputs	– Connections: 100V, 70V, 8Ohm, 4Ohm and 0V.
4	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 loop‑through 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 CAT‑5 (e) cable.
		– Maximum recommended cable distance 5m.
8	Auto Standby	– 4‑pole 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).
