OPERATION
with its parent preset and then setting a target 8300's front panel controls to corre-
spond to the user preset you want to duplicate. The only way to duplicate such a
user preset accurately is via the PC Remote software's backup and restore features,
or by opening the preset in the PC Remote software and manually duplicating each
control setting you see.
The asterisk feature is not included in version 1.0 software.

Advanced Two-Band Controls

The following Two-Band controls are only accessible from the 8300 PC Remote soft-
ware.
2B Master Compression Threshold sets the level where gain reduction starts to
occur in the Master (above 200Hz) band of the Two-Band Compressor.
2B Bass Threshold determines the compression threshold of the bass band in the
Two-Band Compressor. It can be used to set the target spectral balance of the Two-
Band Compressor. As the Two-Band Compressor B
"100%," the 2B B T
ASS
2B Master Attack sets the attack time of the Two-Band Compressor master com-
pressor (above 200Hz).
2B Bass Attack sets the attack time of the Two-Band Compressor bass compressor
(below 200Hz).
The relationship and interaction between 2B Clip, 2B High Frequency Limiting, and
the next two controls is complicated and is best appreciated by listening and ex-
perimenting:
Lookahead determines the lookahead time (in milliseconds) in the two-band com-
pressor. 3.6 milliseconds give minimum overshoot for the factory preset attack time
of 11.0. If you adjust L
shoot. This will cause more voice distortion but will create more transient impact on
percussion because transients will hit the clippers harder instead of being controlled
inaudibly by the lookahead compressor.)
This control does not affect the HD processing chain.
2B High Frequency Clip Threshold sets the threshold of the multiband, distortion-
cancelled clipper in the Two-Band structure's high frequency limiter. Higher numbers
yield more brightness, but also cause more high frequency distortion.
2B Crossover sets the structure of the two-band crossover to Linear or Linear with
No Delay. See AGC C

MB Limit Speech Threshold lets you set the increment (in dB) by which the setting
of the MB L control is reduced when speech is detected. This control allows
