SYSTEM CONFIGURATION
parameters for the AVR 645, we suggest Logic 7
(Cinema or Music) for most analog inputs. For inputs
such as a CD Player, Tape Deck or Tuner, you may
wish to set the mode to Stereo ("Surround Off"), as
they are not typically used with multichannel program
material, and it is unlikely that surround-encoded mate-
rial will be used. Alternatively, the Logic 7 Music mode
is a good choice for stereo-only source material. See
page 60 for information on surround modes.
For digital program material, the AVR will always exam-
ine the data stream and automatically select a Dolby
Digital or DTS mode, as applicable.
To begin the surround setup process, from the
MASTER MENU (Figure 1), press the
© until the cursor is next

to the SURROUND SETUP line. Press the
Set Button pœ until the SURROUND
SETUP menu (Figure 6) is on the screen.

The first line on the menu allows you to select the
input for which the specific surround settings will
be applied. Press the ‹/› Navigation Buttons
© to select the input source to be configured.
The AUDIO IN-PORT and AUDIO IN
lines are for display only and may not be changed
through the SURROUND SETUP menu. The
AUDIO IN-PORT displays the physical con-
nection source for the current active input, and the
AUDIO IN line shows the signal type present.
Note that an UNLOCK message in the AUDIO
IN line indicates that a digital physical input source
has been selected, but that no data stream is present.
When the input selection has been made, press the

the next configuration line.
The ADC SAMPLING line is where you deter-
mine whether the unit's upsampling feature is turned
on or off. The default setting of 48kHz puts the
feature in a bypass, or "off," mode and will pass digital
audio data through the DSP at its native sample rate.
To process incoming 44.1kHz signals at a higher res-
olution, upsampled 96kHz sample rate, press the

to move to the SELECT line.
At the SELECT line, you are able to choose the
specific mode to be used from within the major sur-
round mode group. The choice of modes is governed
by the input type (as some modes such as Dolby
Digital or DTS-ES are not available for analog
sources), as well as by the speaker configuration,
since some modes are only available when a full 7.1
speaker complement is present. The full list of avail-
able modes is detailed in the surround mode chart on
page 60. Also, you may also use the settings in the
SURROUND CONFIG menus to delete modes
you do not normally use from the available choices.
When both a surround mode group and a specific
surround mode have been selected, press the
Navigation Buttons
configuration line.
The DEFAULT SURR mode line is where you
choose the mode that is activated when a digital
source is selected. LAST will activate the last-used
mode for any digital source. If you prefer to always
have a digital source switch to the specific mode
encoded by digital data flags in the incoming audio
data stream, press the
© so that ORIGINAL appears.
Before proceeding to the SURROUND CONFIG
line, it is worth noting that the settings in the sub-
menus attached to that line may require a consider-
able amount of time to complete. Although they are
useful in that they allow you to customize the list of
surround modes that appear in normal use of the AVR,
you may wish to bypass those settings at this time so
that you may complete the configuration process. You
may return to this menu line at a later time, once you
have had a chance to listen to the various surround
modes and determine which you want to "keep" and
which you do not want to use. The settings in this line

the AVR "sounds."
