• Dual Concentric Control
(Inner-Gain/Outer-Limiter Threshold)
• -20/Clip/Limit LED’s
Dual Concentric Control:
Gain. The inner concentric control provides 60dB of gain to the
processed signal. The amplifier has inherent gain of 12dB thus
delivering a total gain possibility of 72dB.
LIMITER THRESH. The outer concentric control sets the
Threshold of the dual domain limiter. The threshold ranges from 0
to +24dB.
-20 / Clip / Limit LED’s
The three LED’s found on each channel are provided to serve
different functions:
-20. The LED farthest to the left is labeled –20 and serves to
monitor whether or not signal is present at the channel output.
Clip. The LED labeled Clip activates at a pre limiter signal level of
+24 dB. Care should be taken to avoid using signal levels that
cause this LED to become active. Signal levels that reach or
exceed this amount of output will cause undesirable artifacts
(distortion) in the channel output signal that is being indicated by
this LED. The signal level is reduced by rotating the channel’s
inner concentric control, counter-clockwise.
LIMIT. The LED farthest to the right is labeled LIMIT. This LED is
activated by signal levels that reach or exceed the level that is pre-
determined by the Threshold setting selected (outer concentric
control). The setting of this control selects the point at which the
