Unless they use the features noted below, 8400 "Low Latency" presets will import
correctly into the 5500:

The 5500's stereo enhancer offers only "Orban 222-style" enhancement. There-
fore, the 5500 will always interpret the 8400 S
will ignore the D

The 5500's multiband compressor/limiter cannot be operated in dual-mono or
partially coupled mode. It is always fully stereo-coupled.
A) The 5500 will always interpret the 8400 MB D

OUPLE
B) The 5500 will always interpret the 8400 B
rameter as set to "0" (i.e., fully coupled).
The 5500's AGC is capable of dual-mono mode, so, unlike the multiband
compressor/limiter coupling parameters, the 5500 interprets all 8400 AGC
coupling parameters normally.

The 5500's 19 kHz protection filter is always O
interpret the 8400 P
The following differences between the 5500 and other Optimod-FMs do not affect
the 5500's ability to import these presets, but are included here for reference.

The 5500's "ultra-low latency" processing uses 8200 clipping technology, up-
dated with anti-aliased clippers operating at 256 kHz sample rate. This mode is
not available on the 8400 but is available on the 8300, 8500, and 8600. It is
available on the 5500 because one application of the 5500 is to replace the 8200
in installations requiring the very low delay (in the range of the 8200's delay).
The 5500 can import 8300 and 8500 ultra-low latency user presets and run them
without compromise.

Switching between an "optimum" or "two-band" preset and an "ultra-low la-
tency" preset requires re-loading DSP code, which causes a two-second audio
mute in the 5500. However, no mute occurs when switching between an "opti-
mum" and "two-band" preset. In the 8400, all processing structures are simulta-
neously active and no audio mute occurs when switching between them.
