6.1. Brief Technical Overview

The output channels are slightly more complex than the input channels in that they are responsible
for the signal routing as well as output signal processing. At the input of each output there is a
matrix mixer (see following diagram) that can source each output from a mix of the four input
channels (A to D). An output can derive its source from a single input by setting the gain of the other
inputs to off. The amount, or level, of input that can be routed to the output is variable from –40dB
to 0dB in 0.1dB steps, or can be switched off completely.

After routing, the resultant signal is passed through the various output processing circuits as shown
below. Processing options include delay, inversion, two independent phase adjustment stages (Phase
Shift and All Pass), filtering, six stages of parametric equalisation, gain/mute, compression and
limiting. All key stages are monitored for signal clipping which, if detected, illuminates the top red
segment at the top of the output signal meter. In addition, the signal is monitored through the
compressor and limiter stages to provide headroom/gain reduction indications at the signal meter.
