ST1 (& ST3) Phono sockets
These are stereo inputs additional to the main stereo channel in-
puts (below). The gain is varied by the ST1 (& ST3) level control
and these inputs can be sent to either the stereo channels or
straight to the L R main bus, depending on the setting of the under-
panel switch. These inputs are unbalanced.
The source for the ST3 input can be switched from the phono
sockets to the USB return signal with the selector switch below the
.

Stereo Inputs 1 (& 3) Level control
Adjust the level of the stereo inputs 1 & 3 from off (fully attenu-
ated) to maximum where it has 10dB of gain.
ST1 (& 3) Routing selector switch
This switch selects whether the ST1 (or ST3) signal is sent to the L
R bus directly, or the stereo channel below. When it is pressed in,
the ST1 (or ST3) signal sums together with the main stereo inputs
ST2 (or ST4).
ST2 (& ST4) 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 Input ST2 (& ST4) Level control
Adjusts the level of the ST2 (& ST4) input. The range is from off to
+10dB.
