5 Advanced Configuration
5.1 Chain Feature
Each channel is provided with an additional header at its input so that another input channel
may be connected to it.
The feature allows a ‘zone’ connected to an input channel to then be ‘Chained’ to a second
input channel.
This can then be repeated for the other channels if required.
Example
shows connection of amplifier inputs 1, 2 & 3 to Zone 1. Amps 1, 2 & 3 will be set as
Masters.
5.2 Connecting Signal Processors ‘Insert’ (‘Send’)
Additional signal processing equipment can be connected into the audio bus – amplifier path.
This is achieved by using a selector cable to connect the required audio bus ‘zone’ to the
appropriate channel ‘Send’ (Do not connect to the ‘I/P’ header).
This will route the selected audio bus zone to the auxiliary port connector ‘Send’ output
terminals.
The input of the signal processing equipment can then be wired to this output. The output of the
signal processing equipment can then be wired back into the amplifier signal path via the ‘Direct
Audio Input’ connections.
