Using Stream Direct; Using Surround Back Channel Processing - Pioneer VSX-919AH-S 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.
• While listening to a source, press
, then press AUTO/ALC/DIRECT
RECEIVER
(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 52.
• ALC – Listening in Auto level control mode
(page 52).
• 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).
• With a 7.1-channel surround system, audio
signals that have undergone matrix
decoding processing through surround
back channel processing to which the Up
Mix function is added are output from the
surround back speakers.
• 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.
