The 8300’s AGC is capable of dual-mono mode, so, unlike the multiband
compressor / limiter coupling parameters, the 8300 interprets all 8400
AGC coupling parameters normally.
The 8300’s 19 kHz protection filter is always O

. Therefore, the 8300 will always
interpret the 8400 P

The following differences between the 8300 and 8400/8500 do not affect the 8300’s
ability to import 8400 presets, but are included here for reference.
The 8300’s “ultra-low latency” processing uses 8200 clipping technology, up-
dated with anti-aliased clippers operating at 256 kHz sample rate. This mode is
available on the 8500 but not on the 8400. It is available on the 8300 because
one application of the 8300 is to replace the 8200 in installations requiring the
very low delay (in the range of the 8200’s delay).
Switching between an “optimum” or “two-band” preset and an “ultra-low la-
tency” preset requires re-loading DSP code, which causes a brief audio mute in
the 8300. However, no mute occurs when switching between an “optimum” and
“two-band” preset. In the 8400 and 8500, all processing structures are simulta-
neously active and no audio mute occurs when switching between them.
