LFE Level Setting
With this setting, you can set the level of the LFE (Low
Frequency Effects) channel for Dolby Digital and DTS.
The level can be set to –
∞
, –10 dB, or 0 dB (default).
If you find that the low-frequency effects are too loud
when using one of these sources, set the level to –10 dB
or –
∞
dB.
Vol Display
With this preference, you can choose how the volume
level is displayed.
Abs (Absolute): Display range is MIN, 1 through 99,
MAX.
Rel (Relative): Display range is –
∞
dB,
–83…0…+16 dB (default).
The absolute value 84 is equivalent to the relative value
0 dB.
The THX Audio settings only affect speaker set A.
The THX Audio settings are explained below.
BGC (Boundary Gain Compensation)
Setting
A room’s boundaries (i.e., walls) and their construction
may make bass sounds louder when the listening posi-
tion or subwoofer is positioned close to such a boundary.
This is called the boundary gain effect. With this setting,
you can compensate for this and achieve a more accurate
and flatter bass response.
On: Boundary Gain Compensation on.
Off: Boundary Gain Compensation off (default).
SB Spc (Surround Back Spacing) Setting
This setting is only available if the SurrBack ch setting
in the Speaker Configuration is set to 2ch.
With this setting, you can specify the distance between
your surround back speakers. To get the best from THX’s
ASA (Advanced Speaker Array) technology, these
speakers should be placed as close together as possible.
0–1 ft (0–0.3 m) (Default):
Select this if the speakers are between 0 and
1 foot (0–30 cm) apart.
1–4 ft (0.3–1.2 m):
Select this if the speakers are between 1 and
4 feet (0.3–1.2 m) apart.
>4 ft (>1.2 m):
Select this if the speakers are more than 4 feet
(1.2 m) apart.
