The Sidechain assignment possibilities in the
MDX 5.1 are very comprehensive. Carefully se-
lecting which channels should be controlled by
which Sidechains, is just as essential as dialing
in the correct Threshold and Ratio values.
It is possible to freely select any or none of three
Sidechains to control each of the main-channels.
This also gives you the option of grouping the
channels. In addition to this, the LFE channel
has its own Sidechain control. This enables e.g.
setting up two Multiband 5.1 algorithms in se-
rial setup, while having six individual Sidechains
available, enabling fully individual Sidechain con-
trols of all channels.
At the Feed page it is possible to make additional
Sidechain link Inputs, for e.g. having the Center-
channel contributing to the Sidechain Inputs of
the two Front channels, to create a more coher-
ent sound from the front-channels.
The illustration above reflects the Processing pa-
rameter set to MDX 5.1 in Normal mode.
Basic operation
At the Setup/Control page it is possible to decide
which Sidechains should control which chan-
nels. Select any of three Sidechains to be as-
signed to any of the five Main-channels. You can
also chose to pass the channels unprocessed
through the algorithm. The LFE channel can be
assigned to its own separate Sidechain, or be
left unprocessed.
Setting a channel to unprocessed will preserve
the processing delay through the algorithm,
keeping the channel time-aligned to the other
(processed) channels.
Sidechain Control
Range – for the five main channels:
– Unprocessed
– Side Chain 1
– Side Chain 2
– Side Chain 3
Range – for the LFE channel:
– Unprocessed
– LFE

The Setup/SC Feed page holds parameters
specifying which Input channels should feed the
three Sidechains.
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.
