OPERATION 43
ENGLISH
Operation
When Dolby Digital 3/2/.1 or DTS 3/2/.1 signals
are being played, the AVR will automatically
switch to the proper surround mode, and no
other processing may be selected.When a Dolby
Digital signal with a 3/1/0 or 2/0/0 signal is
detected you may select any of the Dolby sur-
round modes.
If the EX flag is off, and your receiver has been
configured for 6.1/7.1 operation, you may manu-
ally turn on EX processing as appropriate by sim-
ply selecting the Dolby Digital EX surround mode
as described on pages 26 and 40.When the ES
flag is not present in a DTS bitstream, you may
benefit from a 6.1-channel presentation by select-
ing the DTS+Neo:6 surround mode as described
on pages 26 and 40. In that mode, the DTS Neo:6
algorithms will be used to derive the surround
back channel from the DTS bit-stream information.
Surround Mode Post Processing
Thanks to the power of the AVR 347’s DSP
processor, a variety of surround mode options
are available for most digital signals to deliver
either the native information or to produce an
enhanced sound field to match the number of
speakers in your system. The modes available
and the number of channels available for each
mode will vary depending on the incoming
bitstream, and the configuration of your system,
and are listed in the tables below. The modes
may be selected in the usual manner by
selecting the major Surround Mode Group first,
and then scrolling through the options.
The incoming bitstreams are indicated in the
Lower Display Line
Ò
as described above.
After you have selected a surround mode, after
about 5 seconds, the bitstream will be displayed
briefly before the unit returns to normal
operation.Therefore, you may ascertain the
current bitstream simply by pressing the button
for the major Surround Mode Group and waiting
for a few moments for the bitstream to appear
in the Lower Display Line
Ò
.The bitstream
information will also be displayed after the
source input has been changed.
To use the table below, match the indication in
the display to the Incoming Bitstream listed in
the left column.The available surround modes
are shown to the right.
It is always a good idea to check the readout for
the channel data to make certain that it matches
the audio logo information shown on the back of
a DVD package. In some cases you will see indica-
tion for “2/0/0” even when the disc contains a
full 5.1, or 3/2/.1 signal.When this happens,
check the audio output settings for your DVD
player or the audio menu selections for the specif-
ic disc being played to make certain that the play-
er is sending the correct signal to the AVR.
PCM Playback Indications
PCM is the abbreviation for Pulse Code
Modulation, which is the type of digital signal
used for standard CD playback, and other non-
Dolby Digital and non-DTS digital sources such
as Mini-Disc.When a PCM signal is detected,
the Main Information Display
Ò
will briefly
show a message with the letters PCM, in
addition to a readout of the sampling frequency
of the digital signal.
Connections may be made to either the rear-
panel Optical or Coaxial Inputs
NR
or the
front-panel Digital Inputs
*Ó
.
To listen to a PCM digital source, first select the
input for the desired source (e.g., CD). Next
press the Digital Select Button
Û
G
and
then use the

Buttons
D
on the
remote, or the

Selector Buttons

on
the front panel, until the desired choice appears
in the Upper Display Line
Ò
.
During PCM playback, you may select any
Surround mode except Dolby Digital or DTS, as
shown in the table below. Note that for
convenience, we have included the modes
available for analog sources (including the tuner)
in the chart on the bottom of this page.

LARGEor SMALL.These modes are not available when the Surround Back channels have been configured for multiroom operatioin.
** The Surround Off mode is only available for ananlog sources or the tuner, and requires that the tone controls be removed from the circuitry for “flat” response. Otherwise, the DSP Surround Off
mode may be selected when a two-channel presentation is desired.
For incoming DTS signals, the following modes are available:
