OPERATION 49
ENGLISH
• Two options are available for selecting an input
source using the TC 30 remote.
■ Press the Activities Button
3
to display
the list of preprogrammed activities and
then press the Screen Button
6
to the
left of
LISTEN TO USB. This will both
select the USB input and change the remote
codes so that the buttons will control the
media player on your computer.
■ To directly select the USB input as a source,
first press the Devices Button
4
and
then press the Screen Bnutton
6
to the
left of AV Receiver.When the next page of
options appears in the LCD Screen
7
,
press the Screen Button
6
to the left of
USB.
• To select USB as an input using the ZR 10
remote, press the USB Input Selector D.
When the USB input is selected and the AVR 745
is connected to a compatible computer with one
of the media players mentioned above open, you
may then use the TC 30 to start and stop
playback, as well as move to the next track using
either the commands that appear in the LCD
Screen
7
in conjunction with presses of the
Screen Buttons
6
, or the Transport
Controls
9
.Activity of the Transport buttons
may vary from one media player to another, but
at the very least you will be able to use the Play
and Stop buttons. You may also control the
media player on a connected computer using the
Transport Controls P on the ZR 10 remote.
Once playback is started, the audio from a USB
source is treated the same as any other two-
channel audio source, and you may apply any of
the appropriate surround processing modes.
When playing back audio from a computer via
the USB connection, the internal speakers in a
laptop computer are often muted.
Speaker/Channel Indicators
In addition to the Bitstream Indicators, the
AVR features a set of unique channel-input indi-
cators that tell you how many channels of digital
information are being received and/or whether
the digital signal is interrupted.
These indicators are the L/C/R/LFE/SL/SR/SBL/SBR
letters that are inside the center boxes of the
Speaker/Channel Input Indicators
Ú
in the
front panel Main Information Display
˜
.
When a standard analog stereo or matrix
surround signal is in use, only the “L” and “R”
indicators will light, as analog signals have only
left and right channels.
Digital signals, however, may have one, two, five,
six or seven separate channels, depending on the
program material, the method of transmission
and the way in which it was encoded.When a
digital signal is playing, the letters in these
indicators will light in response to the specific
signal being received. It is important to note that
although Dolby Digital, for example, is referred to
as a “5.1” system, not all Dolby Digital DVDs or
audio tracks selected on DVD or other Dolby
Digital programs are encoded for 5.1.Thus, it is
sometimes normal for a DVD with a Dolby Digital
soundtrack to trigger only the “L” and “R”
indicators.
NOTE: Many DVD discs are recorded with both
“5.1” and “2.0” versions of the same sound-
track.When playing a DVD, always be certain to
check the type of material on the disc. Most discs
show this information in the form of a listing or
icon on the back of the disc jacket. When a disc
does offer multiple soundtrack choices, you may
have to make some adjustments to your DVD
player (usually with the “Audio Select” button or
in a menu screen on the disc) to send a full 5.1
feed to the AVR or to select the appropriate
audio track and thus language. It is also possible
for the type of signal feed to change during the
course of a DVD playback. In some cases the pre-
views of special material will only be recorded in
2.0 audio, while the main feature is available in
5.1 audio. As long as your DVD player is set for
6-channel output, the AVR will automatically
sense changes to the bitstream and channel
count and reflect them in these indicators.
Important Note: When a digital surround
source (Dolby Digital, DTS) is played, the letters
SBL/SBR for the Surround Back channels will
appear only when a DTS ES DISCRETE 6.1 source
is played.Then this surround mode will be
indicated in the front display and on-screen
display. With all other recordings the icons for the
surround back speakers may light (when those
speakers have been configured) to indicate that a
signal will be fed to them (Matrix decoded with
NEO:6, LOGIC 7 or 7 CH Stereo), but no letters
inside will light as the unit will not receive an
input signal for the surround back channels.
The letters used by the Speaker/Channel Input
Indicators
Ú
also flash to indicate when a bit-
stream has been interrupted.This will happen
when a digital input source is selected before the
playback starts, or when a digital source such as
a DVD is put into a Pause mode.The flashing
indicators remind you that the playback has
stopped due to the absence of a digital signal
and not through any fault of the AVR.This is nor-
mal, and the digital playback will resume once
the playback is started again.
Night Mode
A special feature of Dolby Digital is the Night
mode, which enables Dolby Digital input sources
to be played back with full digital intelligibilty
while reducing the maximum peak level and lift-
ing the low levels by
1/4 to 1/3.This prevents
abruptly loud transitions from disturbing others
without reducing the impact of the digital source.
The Night mode is available only when the Dolby
Digital mode is selected.
The Night mode may be engaged at any time
when a Dolby Digital source is playing by
pressing the Devices Button
4
on the TC 30,
followed by the Screen Button
6
at the top
of the row of buttons on the left side of the TC
30, to the left of the
AV RECEIVER image
on the LCD screen.After the list of options
displayed on the LCD Screen
7
changes,
press the Page Left/Right Button
8
to
display the next page of options, and press the
Screen Button
6
to the left of the word
NIGHT. Each press of the button will change
the Night mode setting, as shown in the lower
third of the on-screen display (except when 720p
or 1080i sources are in use).To turn the Night
mode off, press the button as described until
D-
RANGE OFF
is shown.
The Night mode may also be selected to always
be on at either level of compression using the
options in the
DOLBY SURROUND menu.
See page 31 for information on using the menus
to set this option.
IMPORTANT NOTES ON DIGITAL PLAYBACK:
• When the digital playback source is stopped, or
in a pause, fast forward or chapter search mode,
the digital audio data will momentarily stop, and
the channel position letters inside the Speaker/
Channel Indicators
Ú
will flash.This is nor-
mal and does not indicate a problem with either
the AVR or the source machine. The AVR will
return to digital playback as soon as the data is
available and when the machine is in a standard
play mode.
• Although the AVR will decode virtually all DVD
movies, CDs and HDTV sources, it is possible that
some future digital sources may not be compatible
with the AVR.
