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 3, 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: “0-30 cm (0-12 inch),” “>30-122 cm (>12-48 inch),” or “>122 cm (>48 inch)”. For optimum ASA effect, the surround back speakers should be placed as close together as possible.

a. Dolby Digital

The level can be adjusted to either –∞or between –10 and 0 decibels in 1-decibel increments. For Dolby Digital input source signals, the LFE level becomes that set here. A setting of 0 decibels is recommended for optimum performance; however, if the low frequency range is too strong, lower this setting as necessary.

b. DTS

The level can be adjusted to either –∞or between –10 and 0 decibels in 1-decibel increments. For DTS input source signals, the LFE level becomes that set here. A setting of 0 decibels is recommended for optimum performance; however, if the low frequency range is too strong, lower this setting as necessary.

c. MPEG Multi

The level can be adjusted to either –∞or between –10 and 0 decibels in 1-decibel increments. For MPEG input source signals, the LFE level becomes that set here. A setting of 0 decibels is recommended for optimum performance; however, if the low frequency range is too strong, lower this setting as necessary.
