that fully envelops the listener.
• Neo:6 Cinema
Use this mode with any stereo movie (e.g., TV, DVD, VHS).
• Neo:6 Music
Use this mode with any stereo music source (e.g., CD, radio, cassette, TV, 
VHS, DVD).
• Neo:6
This mode uses Neo:6 to expand 5.1-channel sources for 6.1/7.1-channel 
playback.
Audyssey DSX
*8
• Audyssey DSX
Audyssey DSX™ is a scalable system that adds new speakers to improve 
surround impression. Starting with a 5.1 system Audyssey DSX first adds 
Wide channels for the biggest impact on envelopment. Research in human 
hearing has proven that information from the Wide channels is much more 
critical in the presentation of a realistic soundstage than Back Surround 
channels found in traditional 7.1 systems. Audyssey DSX then creates a pair 
of Height channels to reproduce the next most important acoustical and 
perceptual cues. In addition to these new Wide and Height channels, 
Audyssey DSX applies Surround Envelopment Processing to enhance the 
blend between the front and surround channels.
• Dolby Pro Logic II Movie + Audyssey DSX
• Dolby Pro Logic II Music + Audyssey DSX
• Dolby Pro Logic II Game + Audyssey DSX
The combination of Dolby Pro Logic II and Audyssey DSX modes can be 
used.
THX
Founded by George Lucas, THX develops stringent standards that ensure 
movies are reproduced in movie theaters and home theaters just as the 
director intended. THX Modes carefully optimize the tonal and spatial 
characteristics of the soundtrack for reproduction in the home-theater 
environment. They can be used with 2-channel matrixed and multichannel 
sources. Surround back speaker output depends on the source material and 
the selected listening mode.
• THX Cinema
THX Cinema mode corrects theatrical soundtracks for playback in a home 
theater environment. In this mode, THX Loudness Plus is configured for 
cinema levels and Re-EQ, Timbre Matching, and Adaptive Decorrelation 
are active.
• THX Music
THX Music mode is tailored for listening to music, which is typically 
mastered at significantly higher levels than movies. In this mode, THX 
Loudness Plus is configured for music playback and only Timbre Matching 
is active.
• THX Games
THX Games mode is meant for spatially accurate playback of game audio, 
which is often mixed similarly to movies but in a smaller environment. THX 
Loudness Plus is configured for game audio levels, with Timbre Matching 
active.
