OPTIMOD-FM DIGITAL OPERATION

User Presets unless the AGC’s nominal gain reduction is significantly different from
10 dB.
The multiband compressor gate causes the gain reduction in bands 2 and 3 of the
multiband compressor to move quickly to the average gain reduction occurring in
those bands when the gate first turns on. This prevents obvious midrange coloration
under gated conditions, because bands 2 and 3 have the same gain.
The gate also independently freezes the gain of the two highest frequency bands
(forcing the gain of the highest frequency band to be identical to its lower neigh-
bor) and independently sets the gain of the lowest frequency band according to the
setting of the
DJ B
ASS
boost control (in the Equalization screen). Thus, without in-
troducing obvious coloration, the gating smoothly preserves the average overall
frequency response “tilt” of the multiband compressor, broadly maintaining the
“automatic equalization” curve it generates for a given piece of program material.
Note: If the

MB Clipping
sets the drive level to the multiband distortion controlling processing
that precedes the final clipping section. The distortion-controlling section uses a
combination of distortion-cancelled clipping and look-ahead processing to antici-
