4. Installation

The speaker outputs are via Neutrik Speakon connectors. Only 2 of the 4 poles are

used.

Stereo operation

Terminations are as follows:-

Channel A Live (Hot) +

Channel A Return(Cold) - Pin -1

NOTE:

1. Although the "cold" output terminals are nominally at 0V, they should not be joined

together; otherwise cross-talk may be introduced.

2. Because the currents involved are very high, the speaker cables should conform to

the following minimum requirements, otherwise the losses will cause the cables to get

hot and audio power will be reduced:

14A (B1500) or 16A (B2000) - into 4ohm speaker loads

Bridged mono operation

Use centre Speakon connector marked Bridged and connect as follows:

Bridged Live (Hot) +

Bridged Return (Cold) -

When operating in bridged mode, the minimum impedances are doubled. The

minimum load in bridged mode is: 4 ohms (B1500 and B2000).
