STEREO INPUT CHANNELS ST2, 3 & FX
1
Stereo Input Channel ST2
The only difference from stereo input channel ST1 is the labelling of the additional stereo input on phono con-
nectors, labelled as 2 Track Return. This is to indicate that a 2 track (stereo) input can be inserted here for
playback of a stereo recording or incidental music.
2
Stereo Input Channel ST3
Stereo input channel ST3 also has an additional stereo input, but instead of being on phono connectors, it
comes from the USB audio input. The level control, ON switch and routing switch are the same as for stereo
input channel ST1. It is best to leave the ON switch in its UP position when the USB input is not in use. The
phono sockets carry the analogue record output signals that are sourced from the main L R outputs. They are
pre-fade, post L R insert.
Stereo Input Channel ST1
This is stereo input channel ST1 as described on previous pages.

Effects Channel and ST4 input.
The FX or Effects channel has one stereo input (ST4) on jack sockets which adds to the output of the built in
digital effects processor. This stereo input can be used with an external effects processor to return the effects
signal to the main mix.
The phono sockets carry the Alternate stereo output which comes from the selector switches and level con-
trol in the master section.

USB connector & output selection.
A standard USB type B connector plugs in here (cable supplied). The three selector switches determine what is
sent on the USB output. They work on a priority system, so that if more than one is pressed the one nearest
the top takes precedence. So if all 3 are pressed, then the Aux 1 & 2 signals would be sent by the USB device.
Please refer to the section describing using the USB audio port for more details.
