THX Ultra Setup 5
The Cinema Rhapsody permits the adjustment of features that are specific to THX Ultra 2. These two
elements include Boundary Gain settings and Advanced Speaker Array settings.
Boundary Gain Control (BGC)
When the chosen listening room layout (for practical or esthetic reasons) results in the listener being
too close to the rear wall, the resulting bass level can be sufficiently reinforced by the boundary that
the overall sound quality becomes "boomy". Boundary Gain Compensation (BCG) can be switched
on to restore the correct bass performance.

Advanced Speaker Array (ASA)
The optimum blend of ambient and rear directional information provides an enhanced surround expe-
rience over a wider listening area for all multi-channel formats. With stereo surround tracks and multi-
channel music,, the signal is fed unprocessed to the left and right surrounds and, after further process-
ing, to the surround back speakers. This processing uses THX ASA (Advanced Speaker Array) Tech-
nology and provides an enveloping rear surround field over a wide listening area. The adjustment to
the ASA is based on three settings; if the two back surround speakers are less than 12 inches apart, if
they are between 12 and 48 inches apart, or if they are greater than 48 inches apart. To set the ASA
for your system.
