L/R Monitor Meters
Each meter is a
segment LED display which provide a visual indication of
the source selected by the monitor select switches. Calibrated in 3dB steps from
to
each meter is a VU type(average) responding meter with the 0
position indicating an output level of
EFX Returns
By use of the control marked
these inputs can be used to bring signals
from external effects devices back into the stereo mix. A PAN control is used to
place the signals within the stereo image as desired. A PFL switch allows you to
monitor the EFX return signal prior to its level control. The EFX RTN jack is
configured to provide either unity return gain or
return gain. For low level
devices, the return plug should be inserted all the way into the jack
socket: this provides 12dB extra gain. For high level
devices, insert the
plug halfway into the EFX RTN jack to provide unity gain. Alternatively, use a stereo
jack plug and connect the input signal to the ring contact. Use the EFX PFL switch
to help determine the proper position if not certain.
Stereo Return
Two independent low level
stereo inputs are provided for return tape
or stereo effects into the L/R mix. Sends A B are available for mixing the signal to
the Aux buses for wet monitoring. These sends are normally set up as pre-level
mono. Internal jumper links can be altered to reconfigure the sends as post-level
stereo (left to Aux A, right to Aux B) if

sections). The
control positions the Stereo Return signal in the L/R mix
with up to 6dB cut. The MONO switch mixes the Left(tip) and Right(ring) inputs
together and changes the
control to a normal PAN control. The MUTE
switch cuts the signal to L/R and to any Aux sends set for Post-level. The PFL
switch allows the operator to monitor the Return independently of the
control.
L/R Peak Indicator LED
Warns of imminent overload distortion (3dB below clipping) when the signal
level in L/R approaches this threshold. The circuit monitors both the
mix amp
and line amp; even if the fader is down, you will still be notified of mix amp
overload.
L/R Output Faders
Controls the level of the stereo mix to the L/R Balanced outputs.
