OPTIMOD-AM DIGITAL
OPERATION

The shelving equalizer provides control over gain, hinge frequency, and slope (in
dB/octave).
BASS FREQ
sets the frequency where shelving starts to take effect.
This would by the +3 dB frequency for infinite

G
AIN
. For lower bass
gains, the gain is progressively less than +3 dB at this frequency.
BASS GAIN
sets the amount of bass boost (dB) at the top of the shelf.
BASS SLOPE
sets the slope (dB/octave) of the transition between the top
and bottom of the shelf.
Depending on the preset and adjustment of the band 5 compressor/limiter in the
digital processing channel, the 9400’s processing may increase the brightness of pro-
gram material in the digital processing channel. Hence, bass boost is sometimes de-
sirable to keep the sound well balanced spectrally. Adjustment of bass equalization
must be determined by individual taste and by the requirements of your format. Be
