STEREO INPUT CHANNEL ST1
Stereo Return ON switch
This switches the signal on when pressed in. Leaving the switch in
the up position is recommended when the stereo return input is
not in use to minimise unwanted noise being passed through.
Stereo Return Phono sockets
This is an additional stereo input to the main stereo channel input
(below). The gain is varied by the ST RTN control and this input can
be sent to either the stereo channel or straight to the L R main bus,
depending on the setting of the under-panel switch. These inputs
are unbalanced.

Stereo Routing selector switch
This switch selects whether the Stereo Return signal is sent to the L
R bus directly, or the stereo channel 1. When it is pressed in, the
Stereo Return signal sums together with the main stereo input.
Stereo 1 input jack sockets
Standard 1/4” jack sockets for line level stereo signals. Can be used
with a mono input where the L/M input will also connect to the R
input if nothing is plugged in to R.
The Stereo 1 inputs accept unbalanced or balanced signals.
Stereo 1 Level control
Adjusts the level of the ST1 input. The range is from off to +10dB.
Stereo Channel EQ
The Stereo Channel EQ is 2 band with centre frequencies of 12kHz
for the HF and 80Hz for the LF.
