Input Indicators

• When an audio only source is selected, the last video

input used remains routed to the

Video 1/Video 2

Video Outputs

and

Video Monitor Outputs

This permits simultaneous viewing and listening to
different sources.

• When a composite or S-video source is selected, the

video signal for that input will be routed to the

Video

Monitor Output

and will be viewable on a TV mon-

itor connected to the AVR 745.

6-Channel/8-Channel Direct Input

There are four input choices available for use with
sources such as DVD-Audio SACD player or HD-DVD
or Bluray disc player that are connected to the

8-Channel Direct Inputs

. Select the appropriate

input according to the way your system and source
equipment is configured:

• The

6 CH DIRECT

input should be used

when the SBR and SBL inputs are NOT in use and
the input source device has its own internal bass
management system. This input passes the input
from the source directly through to the volume con-
trol without any analog-to-digital conversion, and it
mutes the unused input jacks to prevent unwanted
noise from interfering with system performance.

• The

6 CH DVD AUDIO

input should be used

when the SBR and SBL inputs are NOT in use

and

when the input source does NOT have its own inter-
nal bass-management system. When this input is in
use, the analog source is converted to digital so that
you may use the same bass-management options
for the direct input as are used for all other inputs.
This input also mutes the unused input jacks to pre-
vent unwanted noise from interfering with system
performance.

• The

8 CH DIRECT

input should be used

when an input is connected to all eight

8-Channel

Direct Inputs

and when the input source device

has its own internal bass-management system. This
input passes the input from the source directly
through to the volume control without any analog-
to-digital conversion.

• The

8 CH DVD AUDIO

input should be used

when an input is connected to all eight

8-Channel

Direct Inputs

and when the input source does

not have its own internal bass-management system.
When this input is in use, the analog source is con-
verted to digital so that you may use the same
bass-management options for the direct input as
are used for all other inputs.

Volume and Tone Control

• Adjust the volume to a comfortable level using the

front-panel

or remote

Volume

Up/Down Buttons

• To temporarily silence all speaker outputs, press the

Mute Button

. This will interrupt the output

to all speakers and the headphone jack, but it will
not affect any recording or dubbing that may be
in progress. When the system is muted, the word

MUTE

will flash in the on-screen display (except

when 720p or 1080i sources are in use) and

Upper Display Line

; press the

Mute Buttons

again to return to normal operation.

• The unit’s tone controls may be taken out of the

signal path by pressing the

Tone Mode Button

the front panel

or by pressing the

Devices

Button

on the TC 30 remote and then press-

ing the

Screen Button

to the left of

Tone

Mode

at the bottom of the list of options on the

bottom left side of the

LCD Screen

. The first

press of either button will show a message in the
on-screen display (except when 720p or 1080i
sources are in use) and

Lower Display Line

with the current status of the tone controls. The sys-
tem default is

TONE IN

, which indicates that

the bass and treble controls are active. Press the

⁄

Navigation Buttons

on the TC30

remote or the

‹

›

Buttons

on the front panel

to change the setting to

TONE OUT

, which

is “flat” response without the tone controls
being active.

• When the tone controls are active, the amount of

bass and treble boost/cut may be adjusted up to
12dB in 2dB steps by first pressing the

Tone Mode

Button

on the front panel

or by first pressing

the

Devices Button

on the TC 30 remote and

then pressing the

Screen Button

to the left of

Tone Mode

at the bottom of the list of

options on the bottom left side of the

LCD Screen

two or three times until the desired setting

(

BASS MODE

TREBLE MODE

)

appears in the on-screen display and the

Lower

Display Line

. Next, use the

‹

›

Navigation

Buttons

on the remote or the

‹

›

Navigation Buttons

on the front panel

change the setting as desired. The unit will return to
normal operation within five seconds after the set-
ting is changed.

• For private listening, simply place a standard

1/4" stereo headphone plug or adapter into the

Headphone Jack

behind the door

on the

front panel. The speakers will automatically mute
and a two-channel stereo signal will be sent to the
headphones. The

Lower Display Line

will read

DOLBY H: BP

, indicating that the headphone

output is in the Bypass mode, and to confirm that

no processing is being used. To listen through the
headphones using the Dolby Headphone mode,
simply press the buttons on the remote or front
panel as shown below for changing a Dolby mode.

DOLBY H: DH

will appear in the Lower

Display Line when the Dolby Headphone mode
is in use.

Surround Mode Selection

One of the most important features of the AVR 745
is its ability to reproduce a full multichannel surround
sound field from digital sources, analog matrix
surround-encoded programs and standard stereo
programs.

Selection of a surround mode is based on personal
taste, as well as the type of program source material
being used. For example, motion pictures or TV pro-
grams bearing the logo of one of the major surround-
encoding processes, such as Dolby Surround or DTS
Stereo may be played in either the Dolby Digital,
Dolby Pro Logic II Cinema, DTS Neo:6 Cinema, or
Logic 7 Cinema surround modes, depending on the
source material.

NOTE:

Once a program has been encoded with matrix

surround information, it retains the surround information
as long as the program is broadcast in stereo. Thus,
movies with surround sound may be decoded via any
of the analog surround modes such as Pro Logic II
Cinema, Logic 7 Cinema or DTS Neo:6 Cinema, when
they are broadcast via conventional TV stations, cable,
pay-TV and satellite transmission. In addition, a growing
number of made-for-television programs, sports broad-
casts, radio dramas and music CDs are also produced
in surround sound. You may view a list of these pro-
grams at the Dolby Laboratories Web site at
www.dolby.com.

Even when a program is not listed as carrying inten-
tional surround information, you may find that the Dolby
Pro Logic II, Dolby Pro Logic IIx, Logic 7 or DTS Neo:6,
and the Hall or Theater modes often deliver enveloping
surround presentations through the use of the natural
information present in all stereo recordings.

Surround modes may be changed at any time by
using either the front panel or remote control. To
select a new surround mode from the front panel, first
press the

Surround Mode Group Selector Button

until the desired major surround mode group such

as Dolby, DTS or Logic 7 is selected. Next, press the

Surround Mode Selector Button

to choose the

specific individual surround mode.

To select a surround mode using the TC 30 remote,
first press the

Devices Button

, followed by the

Screen Button

at the top of the row of buttons

on the left side of the TC 30, to the left of the A/V
receiver image on the LCD screen. After the list of
options displayed on the
