6.OUTPUT CHANNELS

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 channel is a routing block that can source the output signal from a single input, a pair of inputs, or all four inputs. In addition, as shown below, the paired inputs can be weighted (default 50:50).

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, lights 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.
