25. OFF-LEVEL THRESHOLD: The solo and the choir groups have adjustable threshold downward expanders
that reduce noise by lowering the signal when the level drops beneath a set point. This not only cleans up
background noise, but also reduces feedback problems by attenuating mics assigned to this group when there
is no activity. An LED indicates that the group is being attenuated. To disable noise reduction, set the control
to minimum (off).
26. COMPRESSION THRESHOLD: In addition to noise reduction, soft-knee compression is available for both
the solo and the choir groups. The threshold is adjustable to set the amount of compression desired. An LED
illuminates to indicate the group is being attenuated. The control should be set so that the light only

illuminates at peaks and is not consistently on. To
disable compression, set the control to maximum
(full clockwise).
27. GROUP MUTE: The Solo and Choir/Inst Group
mute controls disable the signal from these input
groups going to the main Left/Right outputs. You
may also want to mute the Effects at the same
time. The Mute LED lights when the group is
muted.
28. VOCAL ENHANCE: The circuitry of the vocal
enhance has been designed to improve clarity and
definition. The frequencies have been chosen to
work well with speech and singing. The amount is
determined by a concealed preset switch (MIN up,
MAX down).
29. MONITOR CLIP/MUTE: Mutes the monitor
output. The indicator will light when it is muted.
The light also cautions that the monitor signal is
within 2 dB of clipping, and channel send levels or
the master monitor fader level should be reduced.
30. MONITOR MASTER FADER: Sets the overall
level of the signal that is sent to the monitor output
jacks. The headphone/meter select switch can be
used to check the output level with the meter
array.
31. MAIN LEFT AND RIGHT FADERS: These are the master left and right faders. If the main outputs are set
to dual mono, both have the same signal (sum of left and right) and can be used as zone outputs for house
and annex levels etc. These controls are best operated at the 0 (full up) position. It is most important that
