THX Audio Setup
This setting is not set automatically by Audyssey MultEQ
®
Room Correction and Speaker Setup (see page 54).
With the “SurrBack Sp Spacing” setting, you can specify the distance between your surround back speakers.
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 frequencies 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.
SurrBack Sp Spacing
< 1ft (< 0.3m):
Select this if your surround back speakers are between 0 and 1 foot (0–30 cm) apart.
1 ft – 4 ft (0.3 m – 1.2 m):
Select this if your surround back speakers are between 1 and 4 feet (0.3–1.2 m) apart.
> 4ft (> 1.2m) (default):
Select this if your surround back speakers are more than 4 feet (1.2 m) apart.

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 certain
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 regardless of the volume
setting. THX Loudness Plus is automatically 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.
