THX Audio Setup

With the “Surr Back Speaker Spacing” setting, you can specify the distance between your surround back speakers. This setting is used by Speakers A and Speakers B.

If you’re using a THX-certified subwoofer, set the “THX Ultra2/Select2 Subwoofer” setting to “Yes”. You can then apply THX’s Boundary Gain Compensation (BGC) to compensate the perceived exaggeration of low frequen- cies for listeners sitting very close to a room boundary (i.e., wall).

You can also set the THX Loudness Plus. When the

“Loudness Plus” is set to “On”, it is possible to enjoy even subtle nuances of audio expression at low volume. This result is only available when the THX listening mode is selected.

THX Loudness Plus

THX Loudness Plus is a new volume control technology featured in THX Ultra2 Plus™ and THX Select2 Plus™ Certified receivers. With THX Loudness Plus, home theater audiences can now experience the rich details in a surround mix at any volume level. A consequence of turning the volume below Reference Level is that cer- tain sound elements can be lost or perceived differently by the listener. THX Loudness Plus compensates for the tonal and spatial shifts that occur when the volume is reduced by intelligently adjusting ambient surround channel levels and frequency response. This enables users experience the true impact of soundtracks regard- less of the volume setting. THX Loudness Plus is auto- matically applied when listening in any THX listening mode. The new THX Cinema, THX Music, and THX Games modes are tailored to apply the proper THX Loudness Plus settings for each type of content.
