Press MON 1/2 when you wish to route the headphone mix (Aux Send 1 and 2
output) to the Control Room. AUX 3/4, AUX 5/6, GRP 1/2, and GRP 3/4 may also be
selected. 2 TRACK corresponds to the 2 TRACK INPUT jacks on the rear of the
Studio 32. These can be used to listen to the output of a mixdown tape recorder, or
CD player.
MONO
The MONO button, when pressed down, sums the left and right sides of the selected
Control Room mix to monophonic. By using MONO mode, you can check for phase
cancellation and mono capability. This is good to use when you want to hear how
your mix will sound on AM radio or television.
Master L/R Fader
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 Channels, Monitors, Groups and
Aux Returns which have their L/R 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.
Meters
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 pre- or 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 ).
In PFL mode, both meters will show you the post-
TRIM/pre-fader level, so you can adjust it for the
best balance between low distortion and low noise.
You’ll find in this mode that the main meter’s PK
LED will light at almost the same level the
PEAK LED in the channel does. Adjust your trim
so that such flashes are rare, but make sure you’re
getting some yellow segments in the meter. (For
