Decorrelate Tone parameter
Use the Decorrelate Tone parameter to sharpen
or dampen the de-correlation tone in the sur-
round channels.

Threshold parameter
Use the Threshold parameter to set the true-
peak limit threshold. The value set here is relative
to output level.
– For linear audio and most codecs, set the
Threshold parameter to -1 dBFS.
– For AC3, setting the Threshold parameter be-
tween -3 and -6 dBFS is recommended.
Link parameter
The Link parameter defines which limiters work
together.
C, LR, LFE setting
– If the threshold is exceeded in the Center
channel, only that channel is limited.
– If the threshold is exceeded in one of the other
Main channels, all Main channels excluding
Center are limited.
– If the threshold is exceeded on the LFE chan-
nel, only that channel is limited.
LCR, LFE setting
– If a threshold is exceeded in one of the Main
channels, all Main channels are limited.
– If the threshold is exceeded on the LFE chan-
nel, LFE is limited independently.
All setting
– If a threshold is exceeded in any channel, all
channels are limited.
Profile parameter
True-peak limiters may use different profiles.
And although all these profiles are adaptive,
they have been optimized for different applica-
tions. Use a profile that suits the signal being
processed.
The available settings are:
– Dynamic
– AC3 Codec
– Universal
– Loud
– Voice
Please note that if the “AC3 Codec” profile is
used, the limiter threshold for the C channel is
actually 3 dB higher than set.

Output Fader parameter
The Output Fader parameter is a post-limiter
fader. Parameter range is from -100 dB to 12 dB.

Detect parameter – Detection modes
To avoid the need for metadata to control for-
mat switching, UpCon’s detector makes use of
advanced sensing with appropriate hysteresis
and timing computations. The Detect parameter
