Multiband 5.1
English Manual 19
Setting a channel to unprocessed will preserve
the processing delay through the algorithm,
keeping the channel time-aligned to the other
(processed) channels.
Side Chain Control
Range – for the five main channels:
– Unprocessed
– Side Chain 1
– Side Chain 2
– Side Chain 3
Range – for the LFE channel:
– Unprocessed
– LFE

side chain feed page
Multiband 5.1 algorithm – side chain feed page
The side chain feed page Setup/SC Feed page
holds parameters specifying which Input chan-
nels should feed the three side chains.
Normal
Range: Off, On
When this parameter is set to “On” the Input
channels selected to be controlled by the re-
spective sidechain will also Input to the side-
chain.
Add 1, Add 2 and Add 3
Range:
Off, LFr Max, RFr Max, Cnt Max, LSr Max,
RSr Max, Xt Max, LFr Sum, RFr Sum, Cnt
Sum, LSr Sum, RSr Sum, Xt Sum.
These parameters enable extra channels to be
assigned to the respective Sidechain Input. The
extra Sidechain Input channels will not be pro-
cessed by the sidechain.
The Sum settings will add the Input to the side-
chain, whereas the Max settings only will con-
tribute to the sidechain if the level exceeds the
other Input channel levels.

Multiband 5.1 algorithm – Expander – main
page
Pressing Threshold, Range, Ratio, Attack and
Release keys will immediately assign Lo, Mid, Hi,
All and LFE values for these parameters to Fad-
ers 1 to 4.
Be aware that the range of the All parameter is
relative to the settings of the same parameters in
the Compressor section.
Threshold
Range: -50 dB to 0 dB (in 0.5 dB steps)
When the signal drops below the set Threshold
point the Expander starts to generate downward
expansion.
Range
Range: -40 dB to 0 dB in 0.5 dB steps
Sets the maximum range of the expansion.
Ratio
Range: Off to Infinity
Sets the Expansion Ratio below the Threshold
point.
