Basic Operation
For 6.1 or 7.1 channel playback of 5.1 Channel Sources:
SX (Studio extension)
You can only use this mode if you have setup this amplifier for use with surround back speaker(s) (see
pages 12, 26 & 38-40 ) and select 7.1 in LISTENING CH SELECT (see p.47).
This mode adds surround back channel(s) to 5.1 channel sources to give 7.1 channel surround sound. The
sound you hear from the surround back speaker(s) is the same as the surround speakers. This recreates a
5.1 channel surround sound mixing studio or theater, which would usually have more than 6 speakers. The
display shows the format of the source played.
TX (Technical extension)
You can only use this mode if you have setup this amplifier for use with surround back speaker(s) (see
pages 12, 26 & 38-40 ) and select 7.1 in LISTENING CH SELECT (see p.47).
This mode generates surround back channel(s) for conventional 5.1 channel sources to give 7.1 channel
surround sound. Any 5.1 channel source can be used, but some movies have soundtracks that sound
especially good with TX mode on.
With 6.1 channel playback compatible sources, the TX mode is automatically selected when the
LISTENING CH SELECT is set to AUTO (default).
HOME THX modes
THX and HOME THX are technical standards created by Lucasfilm, Ltd. for cinema and home theater sound. The
aim of HOME THX is to improve the sound of straight decoding to make home theater audio more like the sound
you hear in a cinema. See also page 93-94 for more information.
For all speaker playback of any source:
THX CINEMA
This mode will play any source through all the speakers in your system.
For 2 channel sources only:
After selecting one of the following modes the display shows the mode you selected, then, after a few
seconds, shows THX CINEMA.

For 6.1 or 7.1 channel playback of 5.1 channel sources:
THX SURROUND EX
You can only choose this mode if you have set up this amplifier for use with surround back speaker(s) (see
pages 12, 26 & 38-40 ) and select 7.1 in LISTENING CH SELECT (see p.47).
For true 6.1 channel cinema sound, Dolby Digital Surround EX encoded discs should be played with THX
Surround EX processing. However, it will also generate surround back channel(s) from any Dolby Digital 5.1
or DTS 5.1 channel disc (when playing a DTS disc, the display shows DTS-ES +THX).
With 6.1 channel playback compatible sources, the THX SURROUND EX mode is automatically selected
when the LISTENING CH SELECT is set to AUTO (default).
