Up for POST Fader, the audio signal will be affected by the main Channel
Fader; Down for PRE Fader, the signal is sent out before reaching the
main fader. AUX 2 is configured as POST-Fader; However, AUX 2 can
also be configure as PRE-Fader through any internal modification.

4.9 PAN

This is the PANORAMA control, or balance control. You can adjust
the stereo image of the signal via this Control. Keep this control in
center position and your signal will be positioned in the middle of
stage. Turn this control fully counterclockwise and the signal will be
present only on the left speaker and vice-versa. Of course a wide
number of intermediate positions is available.

4.10 MUTE / ALT 3-4

Each channel is equipped with the MUTE / ALT 3-4 switch. Pressing
this switch is used to route the channel signal to ALT 3-4 output
instead of the main mix and the LED beside MUTE/ ALT 3-4 will
illuminate.

4.11 SOLO

Pressing this switch allows you to monitor the signals through your
headphone or CONTROL ROOM, then the SOLO signal will replace
other signals, and be also sent to the CONTROL ROOM, PHONES
and METERs. Usually use the solo in live work to preview channels
before they are let into the mix.
It is useful to set an instruments's input level and EQ, and you can
also solo any channel that you want to. The SOLO switch never affects
any mix other than the CONTROL ROOM mix.

4.12 SOLO LED

Each channel is equipped with the SOLO LED display. When the SOLO button was engaged, the LED on corres-
ponding channel will illuminate.

4.13 PEAK

Inside your S-12 the audio signal is monitored in several different stages and then sent to the PEAK Led. When this
Led blinks, it warns you that you are reaching signal saturation and possible distortion. The PEAK Led will blink with
a level that is 6dB before actual clipping.

4.14 FADER
