DL231 OPERATORS MANUAL

LED BAR DISPLAY is a dual function facility which measures output level (input level if

The VU meter and threshold controls are calibrated to show 0VU at +4dB

In the gain reduction mode, all the red LED's are very slightly illuminated at all

times. This is quite normal and does not indicate a fault condition.

A three position switch selects ratios of 1:2, 1:5 or 1:20 provides

gating characteristics. Gating can be regarded as the opposite of

limiting.

couples the control circuits of both compressors to prevent image

shifting when treating stereo material on a final mix. The peak

limiters can also be used if desired but they remain independent.

Operational controls should be set the same on both channels when

linked.
