Using Stream Direct; Using Surround Back Channel Processing; Using The Virtual Surround Back Mode - Pioneer VSX-LX52 Operating Instructions Manual

Listening to your system

Using Stream Direct

Use the Stream Direct modes when you want to hear the
truest possible reproduction of a source. All unnecessary
signal processing is bypassed, and you're left with the
pure analog or digital sound source.

SETUP
• While listening to a source, press
press AUTO/ALC/DIRECT (AUTO SURR/ALC/STREAM
DIRECT) to select the mode you want.
Check the digital format indicators in the front panel
display to see how the source is being processed.
• AUTO SURROUND – See Auto playback on page 50.
• ALC – Listening in Auto level control mode (page 50).
• DIRECT – Sources are heard according to the
settings made in the Surround Setup (speaker
setting, channel level, speaker distance, acoustic
calibration EQ, and X-curve), as well as with dual
mono, the input attenuator, and any sound delay
settings. You will hear sources according to the
number of channels in the signal.
• PURE DIRECT – Analog sources are heard without
any digital processing. No sound is output from the
Speaker B in this mode.
Using surround back channel
processing
• Default setting: SBch ON
You can have the receiver automatically use 6.1 or 7.1
decoding for 6.1 encoded sources (for example, Dolby
Digital EX or DTS-ES), or you can choose to always use
6.1 or 7.1 decoding (for example, with 5.1 encoded
material). With 5.1 encoded sources, a surround back
channel will be generated, but the material may sound
better in the 5.1 format for which it was originally
encoded (in which case, you can simply switch surround
back channel processing off).
Note
1 • You can't use the Virtual Surround Back mode when the headphones are connected to this receiver or when any of the stereo, Front Stage
Surround Advance or Stream Direct mode is selected.
• You can only use the Virtual Surround Back mode if the surround speakers are on and the SB setting is set to NO or if Front Bi-Amp, Speaker B
or ZONE 2 is selected at Surr Back System.
• The Virtual Surround Back mode cannot be applied to sources that do not have surround channel information.

• Press RECEIVER , then press SBch repeatedly to
cycle the surround back channel options.
Each press cycles through the options as follows:
• SBch ON – Matrix decoding processing for
generating the surround back component from the
surround component is turned on.
• SBch AUTO – Matrix decoding processing for
generating the surround back component from the
surround component is switched automatically.
Matrix decoding processing is only performed when
surround back channel signals are detected in the
input signals.
• SBch OFF – Matrix decoding processing for
generating the surround back component from the
surround component is turned off.

Using the Virtual Surround Back mode

• Default setting: OFF
When you're not using surround back speakers,
selecting this mode allows you to hear a virtual surround
back channel through your surround speakers. You can
choose to listen to sources with no surround back
channel information, or if the material sounds better in
the format (for example, 5.1) for which it was originally
encoded, you can have the receiver only apply this effect
to 6.1 encoded sources like Dolby Digital EX or DTS-ES.
• Press SBch repeatedly to cycle the virtual surround
back channel options.
Each press cycles through the options as follows:
• VirtualSB ON – Virtual Surround Back is always used
(for example, on 5.1 encoded material)
• VirtualSB AUTO – Virtual Surround Back is
automatically applied to 6.1 encoded sources (for
example, Dolby Digital EX or DTS-ES)
• VirtualSB OFF – Virtual Surround Back mode is
switched off
