Table 8 – Surround Modes
Surround Mode Description
Dolby Digital Provides up to five separate main audio channels and a dedicated
low-frequency effects (LFE) channel. May be encoded for Night mode,
which allows the user to apply a compression setting that maintains
intelligibility of softer passages while reducing the loudness of dynamic
passages to avoid disturbing others.
Dolby Digital EX An expansion of Dolby Digital 5.1 that adds a surround back channel
which may be played through one or two surround back speakers. May
be manually selected when a non-EX Dolby Digital stream is detected.
Dolby Digital Stereo Delivers a 2-channel downmix of Dolby Digital materials.

Game channels and subwoofer for total immersion in the video gaming

Dolby Pro Logic IIx An expansion of Dolby Pro Logic II that adds a surround back channel
Mode Group which may be played through one or two surround back speakers. The
Dolby Pro Logic IIx modes may be selected not only with Dolby Digital bit-
streams, but thanks to the AVR 247's post-processor, they may also be used
with some DTS bitstreams to add a surround back channel to 5.1 modes.
Dolby Pro Logic IIx This mode is similar to Dolby Pro Logic II Movie, with an added surround
Movie back channel. In addition, it may be selected even when some types of
DTS signals are present for a somewhat different presentation.
