The master
music system threshold input
pot controls all the channel thresholds, as
does the sensing mics’s input gain trim control. If all the channel
auto mix gain
displays
stay at full gain, the threshold signal is missing or too low.
If not using the
NOM
(Gain Limiting) function, it is OK to mute the channels on the
board. However, if
NOM
is on, mute on the controller otherwise noise at muted mics
can cause unwanted attenuation of the active mics.
The Music System does not maintain constant ambience like the Speech System. If
gating of the ambience is annoying, the effect can be smoothed two ways:
• Keep one mic always open by turning
last hold
on: press both the master
override
and
preset
buttons at once. Their LEDs blink to indicate when
last hold
is on;
toggle it off the same way. The
last hold
function keeps the last mic on that stays
above -3 dB gain for 1/2 second. When another mic passes the same criteria, it be-
comes the
last hold
mic.
OR
• Reduce the maximum attenuation depth by turning the
depth
knob clockwise to
around -10 dB. This limits the range of downward expansion and mixes in a steady
ambience.
NOTE: The Music and Speech Systems operate independently but the
depth control
is global to both. Use different groups if necessary.
