The input impedance is high enough (20K ohms balanced) to allow ”daisy-chaining”, or multiple parallel input connections. The headroom of the input circuits is also high enough to accept the maximum output level from virtually any low-level signal source. Balanced signals are less sensitive to AC hum and radio interference. The source impedance should be less than1Kohms to avoid high frequency losses in long signal cables.

7.1.2Unbalanced inputs

To connect an unbalanced source, connect pin 3 (ring on TRS jack) to the shield of the connector. If you leave one pin disconnected, you will lose 6 dB’s in level.

A better method of connecting unbalanced sources is shown in below. This is similar to the connection for balanced lines, but pin 3 is connected to the shield at the source. The hum and noise rejection for the cable is equivalent to that of a balanced line. To minimize hum in the audio, use balanced inputs whenever possible.

7.2Connecting loudspeakers

Loudspeaker connections are made via the two Neutrik NL4FC Speakon connectors. The Speakon connector is designed for high power loudspeaker use and meets all worldwide safety requirements.

Connections.

The Speakons are wired:

Channels A, B output connector

Pin +1, Pin –1 = Output A

Pin +2, Pin –2 = Output B

Channels C, D output connector

Pin +1, Pin –1 = Output C

Pin +2, Pin –2 = Output D
