Format Con(vert) parameter
Use the Format Convert parameter to specify if
and how the signal being processed should be
converted.
Off setting
To disable Format conversion, set the Format
Convert parameter to Off.
UpCon setting
To automatically upconvert a stereo signal re-
ceived at the input to 5.1, set the Format Convert
parameter to UpCon.
If you set the Format Convert parameter to Up-
Con and the input format is already 5.1, the sig-
nal will pass the Engine without format conver-
sion.
Downmix setting
To automatically downmix a 5.1 signal received
at the input to stereo, set the Format Convert
parameter to Downmix.
If you set the Format Convert parameter to
Downmix and the input format is stereo, the sig-
nal will pass the Engine without format conver-
sion.

Gain Center parameter
When you have set the Format Convert parame-
ter on UpCon's Main page to Downmix, the Gain
Center parameter can be used to apply a static
gain to the Center channel before delay and true-
peak limiting.
If the processed input signal is already in stereo,
this parameter has no effect.
The default for the Gain Center parameter is
-3 dB, which corresponds to standard downmix
in AC3 decoders. Because the algorithm has a
high internal headroom, there is no overload risk
if the Gain Center parameter is set to 0 dB (or
even positive gain), thereby putting emphasis to
center channel content such as dialog.
Gain Surround parameter
The Gain Surround parameter can be used to
apply a static gain to the surround channels be-
fore delay and true-peak limiting.
If the processed input signal is already in stereo,
this parameter has no effect.
The default is -6 dB, which corresponds to stan-
dard downmix in AC3 decoders. Because the
algorithm has a high internal headroom, there is
no risk of overload if the parameter is set to 0 dB
(or even positive gain), thereby putting emphasis
to surround channel content such as audience
and room sound.
