OPERATION

OPERATION 35

• 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

Upper Display Line

Press the

Mute Button

again to return to

normal operation.

• You may adjust the bass and treble tone controls

at any point during a listening session by pressing
the

Tone Mode Button

until

TONE IN

appears in the

Lower Display Line

. Press

the

Tone Mode Button

again until either

TREBLE MODE

BASS MODE

appears in the

Lower Display Line

, and then

use the

‹

Buttons

)

to boost or cut the low

or high frequencies by up to ±10dB, in 2dB steps,
until the desired setting is achieved.

• You may also totally remove the tone controls from

the circuit so that the output is “flat” at any time by
pressing the

Tone Mode Button

and then

pressing the

‹

Buttons

)

so that

TONE

OUT

appears in the on-screen display and the

Lower Display Line

• The tone controls may also be adjusted using the

AUDIO SETUP

submenu as described on

page 23.

• For private listening, plug the 1/4" stereo phone

plug from a pair of stereo headphones into the
front-panel

Headphone Jack

. When the

headphone plug is connected, all speakers will be
muted and

DOLBY H:BP

will appear in the

Lower Display Line

, indicating that the head-

phone output is in the Bypass mode, and to confirm
that no processing is being used. When the head-
phone plug is removed, the audio feed to the
speakers will be restored.

• When the headphones are in use, you may take

advantage of the Dolby Headphone modes to bring
added spaciousness to headphone listening. Press
the

Dolby Mode Select Button

or the

Surround Mode Group Selector

to cycle

through the three Dolby Headphone modes and
select the one that you prefer.

Surround Mode Selection

One of the important features of the AVR 340 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 or IIx Movie, DTS Neo:6 Cinema, or
Logic 7 5.1 or 7.1 Cinema surround modes.

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 Dolby Pro Logic IIx–
Movie, 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 recorded in
surround sound.

Even when a program is not listed as carrying inten-
tional surround information, you may find that the Dolby
Pro Logic IIx, Logic 7 or DTS Neo:6, VMAx 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. Any
changes made to the surround mode for that source
will be retained in the AVR’s menu, even after another
source is selected, or if the AVR is placed in Standby
mode. 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 select-
ed. Next, press the

Surround Mode Selector Button

to choose the specific individual surround mode.

To select a surround mode using the remote, press
the button for the major surround mode group that
includes the mode you wish to choose from:

Dolby

DTS Surround

DTS Neo:6

Logic 7

Stereo

DSP Surround

The first press of the button will show the current
mode from that group. To cycle through the available
modes in that group, press the button again until the
desired mode appears in the

Lower Display Line

, the on-screen display and in the

Surround

Mode Indicators

. As the surround mode

changes, the appropriate

Surround Mode Indicator

will light to indicate the current mode.

At times, it is possible that more than one indicator will
light. This can occur when the DSP Surround Off
mode has been selected, or when post-processing is
being used with an input signal, such as when the
Dolby Digital 2.0 plus Dolby Pro Logic IIx mode is
used to create a 7-channel presentation of a two-
channel signal.

The Dolby Digital, Dolby Digital EX and DTS 5.1,
DTS-ES Matrix and DTS-ES Discrete modes may only

be selected when a digital input is in use and a digital
signal in that format is present. In addition, when a
digital source is present, the AVR 340 will automatically
select and switch to the correct mode, regardless of
the mode that has been previously selected. For more
information on selecting digital sources, see the Digital
Audio Playback section.

The Dolby Pro Logic IIx modes are available only
when the AVR 340 has been configured for 6.1/7.1
operation by setting the Surround Back speakers as
either

LARGE

SMALL

as described on page

28. These modes provide a matrixed 6.1-channel
presentation of analog sources..

When the 6-channel/8-channel direct inputs are in
use there is no surround processing, as these inputs
take the analog output signals from an optional, exter-
nal DVD-Audio or SACD player, or another source
device and carry them straight through to the volume
control without any further digital processing.

To listen to a program in traditional two-channel stereo,
using the front left and front right speakers only (plus
the subwoofer, if installed and configured), press the

Stereo Button

until

SURROUND OFF

appears in the

Lower Display Line

, or press the

Surround Mode Group Selector

until the Stereo

modes appear in the on-screen display and

Lower

Display Line

and then press the

Surround Mode

Select Button

until

SURROUND OFF

appears in the on-screen display and

Lower Display

Line

When an analog audio source is in use, you may
activate an analog bypass Surround Off mode, if you
have removed the tone controls from the processing
circuitry. This is done by pressing the

Tone Mode

Button

and using the

‹

›

Buttons

until the

TONE OUT

message appears in the

Lower Display Line

, or using the

AUDIO

SETUP

menu.

If the tone controls are active (

TONE IN

), or

if you have selected the digitized Surround Off mode,
the DSP icon will appear in the

Surround Mode

Indicators

, and the message

SURROUND

OFF

will appear in the lower line of the semi-OSD

display. The DSP icon indicates that the incoming sig-
nal is being digitized and any bass management set-
tings are being applied. This mode is recommended
when your front speakers are not capable of repro-
ducing the lower frequencies and are thus used with a
subwoofer.

When the DSP icon is not lit in Surround Off mode
with an analog audio input in use, the AVR is in analog
bypass mode. The signal is being routed directly to the
volume control, without entering the digital domain and
without any bass management settings being applied.
This mode is desirable when your left and right speak-
