ETERS
The L and R meters will display whatever is selected as the Control Room source,
including SOLO. When SOLO is on, the meters show you the post-fader level of an
individual Channel. These are peak-type meters which respond to the immediate
level.
When the meters read “0” (top green LED), the signal is at its
nominal output (+4 dBu balanced, -2 dBu unbalanced) RMS.
Typically, signals should be lighting a few yellow LEDs. When
the top red LED “PK” flashes, , signal is at +18 dB over nominal
(that’s +22 dBu in a balanced circuit, +16 dBu in an unbalanced
circuit). But you still have 5 to 6 dB of headroom before the
summing amps distort (although, depending on your settings,
you may be clipping some other part of the mixer in order to
get level).

The Master L/R fader adjusts the total output level of the stereo signal. It gets its
signal from the stereo busses, which are fed by any of the Channels, Monitors,
Groups and Aux Returns which have their L/R or LINK switch down. They send
signal to the MAIN OUT L and R jacks, and the CONTROL ROOM switch (where it
can be heard if all other switches are up). Unity gain is achieved when the fader is all
the way up.

The Groups may be used as sends to the tape recorder in recording applications, or
as subgroups or zone masters in PA applications.
LINK TO L/R
SWITCH
This switch is primarily used when submixing for PA applications, or possibly
during a complicated recording mixdown. The LINK TO L/R switch functions
essentially the same as the LINK TO L/R switch under the MONITOR 1/2 MASTER:
if the switch is up, anything routed to a group only goes to the group output and the
four DIRECT OUT SOURCE switches. When the switch is down, the group is sent to
the L/R mix as well.
For example, if you have six different drum mics that are in perfect balance with each
other, but you need to bring the overall level of the drums down in the PA, turn the
