1-4. THX Audio Setup sub-menu
Use this sub-menu to configure the THX Audio settings such as
Boundary Gain Compensation™ and Advanced Speaker Array™.
Advanced Speaker Array: When you set up your home theater
system using all eight speaker outputs (Left, Center, Right, Surround
Right, Surround Back Right, Surround Back Left, Surround Left and
Subwoofer) and the two Surround Back speakers are placed close
together as shown in the speaker placement diagrams on page 22,
you can take advantage of THX’s Advanced Speaker Array (ASA)
technology. ASA optimizes the surround sound experience using
two new modes; THX Ultra2 Cinema and THX MusicMode.

a. THX Ultra2 Subwoofer
Set “Yes” if your subwoofer conforms to the THX Ultra2 standard or
if the playback capability of its bass range extends down to 20 Hz.
Otherwise, set “No.”
b. Boundary Gain Compensation
Room boundaries (walls) or other characteristics (such as wall
construction) may increase the perceived acoustics levels at low
frequencies. Depending on the listener's and the subwoofer's
position, the listener may experience an excessive bass effect.
The purpose of this feature is to compensate for excessive bass
resulting from a boundary gain effect.
On: Boundary Gain Compensation is applied.
Off: Boundary Gain Compensation is not applied.
c. Distance between Surr Back Sp
Measure the distance between your two surround back speakers and
then choose the setting that corresponds to your measurement: “0-12
inch (0-30 cm),” “>12-48 inch (>30-122 cm),” or “>48 inch (>122
cm)”. For optimum ASA effect, the surround back speakers should
be placed as close together as possible.
