(8) GAIN REDUCTION (dB)
This series of five LED's displays the amount of gain
reduction in calibrated decibel readings at 0, 4, 8, 16 and 24.
These diodes will not light when the COMP switch is in the OUT
position.
(9) EXP GATE
This LED lights when the expander/noise gate circuit is in
use, and when the signal present is below the threshold (deter¬
mined by the setting of the EXP GATE control (2)). When this LED
turns off, the signal present is above the threshold setting
and is being processed accordingly.
(10) DETECT LIMIT 32dB
When this LED lights, maximum gain reduction of 32dB has
been reached. It also indicates that the detect circuit is over¬
loading and can no longer control the operation of the VCA on a
one-to-one basis. Please note that there is 32dB more system
headroom above the overload point of the detect circuit, so this
LED does not indicate distortion of the audio signal.
(11) LINK
When this switch is in the DUAL MONO mode (UP), the front
panel controls for each channel will operate independently. In
the STEREO mode (DOWN), VCA operation is linked and both channels
will be processed together.
NOTE: The VCA will link with EXP GATE controls via the detect
signal from the channel which is set at the higher
threshold level. Both controls must be ON for stereo
operation of the expander/noise gate function; if
either control is OFF, single channel operation
results. Turn both controls OFF if you do not require
this function for stereo processing.
