Page 72 2-47 OPTIMOD TRIO-AM  LF GAIN determines the amount of peak boost or cut (in dB) over a 10 dB range. threshold of limiting of the 150Hz band has been substantially lowered so that more gain reduction (and thus, less bass) is produced.
Page 73 2-48 OPTIMOD TRIO-AM attempt to keep the gain constant) to prevent excessive stridency in program material that already has a great deal of presence power. Therefore, with large amounts of gain reduction, the density of presence region energy will be increased more than will the level of energy in that region.
Page 74 (necessary to control occupied RRF bandwidth adequately) can produce audible ringing, which many people find objectionable. By limiting the amount of boost at the cutoff frequency of the OPTIMOD TRIO- AM-AM lowpass filter, you can reduce the audibility of filter ringing.
Page 75 2-50 OPTIMOD TRIO-AM If you like a larger-than-life, “chesty” sound on male voice, set this control O , which allows band 1 and band 2 to be gated independently. The amount of bass boost will depend on the fundamental frequency of a given voice. If the fundamental frequency is far above 100Hz, there will be little voice energy in the bottom band and little or no audio bass boost can occur even if the gain of the bottom band is higher than the gain of its neighbor.

Note that INAL RIVE these ranges are relative, and do not indicate the exact amount of clipping. 0dB refers to the average setting that we have found to be the best compromise for many settings of the other controls.

Page 83 2-58 OPTIMOD TRIO-AM When the release time of the multiband compressor is set to its faster settings, the setting of the M ULTIBAND control becomes much more critical to sound quality because density increases as the control is turned up.
Page 84 MB GATE (“Multiband Gate Threshold”) control determines the lowest input level that will be recognized as program by OPTIMOD TRIO-AM-AM; lower levels are considered to be noise or background sounds and cause the AGC or multiband compressor to gate, effectively freezing gain to prevent noise breathing.
Page 85 2-60 OPTIMOD TRIO-AM MB G DJ B HRESH DwnExp Thr (“Downward Expander Threshold”) determines the level below which the single-ended noise reduction system’s downward expander begins to decrease system gain, and below which the high frequencies begin to become low-pass filtered to reduce perceived noise. Activate the single-ended dynamic noise reduction by setting the D control to a setting other than OFF.
