THX Ultra Setup 5
The Cinema Reference 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.
1 Turn the Mode knob clockwise until the display’s second line reads SETUP MENU and then
press the Mode knob.
2 Turn the Mode knob clockwise until the display’s second line reads PRO SETUP and then
press the Mode knob.
3 Turn the Mode knob clockwise until the display’s second line reads STEP 5 THX and press the
Mode knob.
4 Turn the Mode knob until the display’s second line reads BOUNDRY GAIN and press the
Mode knob.
5 Turn the Mode knob to turn Boundry Gain (BNDRY GN) ON or OFF and then press the Mode
knob. Continue below.
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.
1 If you are still in the STEP 5 THX setup menu from the above step, turn the Mode knob until the
display reads ADJ SPKR ARY (Adjust Speaker Array), then press the Mode knob. If you are
not in the STEP 5 THX setup menu, follow the instructions from step 1 in the section above.
2 Turn the MODE knob to select between ASA < 12” (ASA less than 12 inches), ASA 12”-48”
(ASA between 12 and 48 inches), and ASA > 48” (ASA greater than 48 inches). Then press
the Mode knob.
3 To return to other Pro Setup features, turn the Mode knob clockwise until the display’s second
line reads BACK TO MAIN and then press the Mode knob. To completely exit the setup
menu, turn the Volume knob.
