Dolby Pro Logic IIx
Dolby Pro Logic II
Dolby Pro Logic IIx expands any 2-channel 
source for 7.1-channel playback. It provides 
a very natural and seamless surround-sound 
experience that fully envelops the listener. 
As well as music and movies, video games 
can also benefit from the dramatic spatial 
effects and vivid imaging.
If you’re not using any surround back 
speakers, Dolby Pro Logic II will be used 
instead of Dolby Pro Logic IIx.

Surround (Pro Logic) movie (e.g., TV, 
DVD, VHS).

Use this mode with any stereo or Dolby

CD, radio, cassette, TV, VHS, DVD).

those that bear the Dolby Pro Logic II logo.

7.1-channel playback.
Dolby Pro Logic IIz 
Height
Dolby Pro Logic IIz Height is designed to 
more effectively use existing program 
material when height channel speaker 
outputs are present. Dolby Pro Logic IIz 
Height can be used to upmix a variety of 
sources from movies and music, but are 
particularly well-suited to upmix game 
content.
Dolby EX
These modes expand 5.1-channel sources for 
6.1/7.1-channel playback. They’re especially 
suited to Dolby EX soundtracks that include 
a matrix-encoded surround back channel. 
The additional channel adds an extra 
dimension and provides an enveloping 
surround sound experience, perfect for 
rotating and fly-by sound effects.

Audyssey DSX
• 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.
