MONITOR MATRIX: This is used to select the Surround Monitor Matrix. In 5.1 Sur-
round mode, you can select 5.1, 3-1, or ST. In 3-1 Surround mode, you can select 3-1 or ST.
When a down mix Monitor Matrix is selected, you can attenuate signals by using the ATT
parameters. The following diagrams, which show the Monitor Matrixes available in each
Surround mode, are displayed when this parameter is selected.
BASS MANAGE: This parameter is used to select the
five preset Bass Management modes for use with 5.1 Sur-
round mode and the 5.1 Monitor Matrix. The presets
cannot be selected when other Surround modes or Mon-
itor Matrixes are selected. Use the ON/OFF button to turn
Bass Management on and off. When off, the Bass Man-
agement filters are set to THRU and the discrete 5.1 chan-
nel-to-LFE feeds are muted. The Bass Management
diagram and parameters shown here are displayed when
this parameter is selected. Bass Management parameters can be set as follows.
“80-12” means a cutoff frequency of 80 Hz and a filter response of –12 dB/octave. “L” means
Linkwitz filter. Other filters are Butterworth.
The following table lists the Bass Management preset parameter values (“w/BS” means with
Bass Management). SMALL speakers are assumed for the presets.
