Bass Management
LFE Mode
Range: Extract, Distribute, Inactive
When the LFE Mode parameter is set to Distrib-
ute, the Bass Management enables you to add
LFE information to the six Output channels in
the system. This can normally be compared to a
5.1 -> 5.0 process, but it can also be a 5.1 -> 5.1
process, leaving the LFE channel unprocessed,
while adding LFE information to the five Main-
channels. The Bass Management is placed just
before the Output Format conversion.
Main Channels
Lo Cut
Range: 10 to 200 Hz
Sets the frequency for the Lo Cut filter, on the
five main Output channels (LFr, RFr, Cen, LSr,
RSr)

tract signal from the Main Channels and feed
them to the LFE channel. Use this mode when
converting a 5.0 format to 5.1.
LFE To Main Channels – Distribute mode
In this mode, the Level controls are used to dis-
tribute the LFE signal to the five Main Channels.
Use this mode when converting a 5.1 format to
5.0.
