Operation

Note that when Dolby Digital 2.0 signals (e.g.

D.D. 2.0" tracks from DVD), that are encoded

with Dolby Pro Logic information, are received

via any digital input, the Dolby Pro Logic II

Movie mode will be selected automatically (in

addition to the Dolby Digital mode) and will

decode a full range 5.1 channel surround sound

even from those recordings.

To create wide, enveloping sound field environ-

ments and defined pans and flyovers with all

analog stereo recordings select the Dolby Pro

Logic II Music or Emulation mode or Harman

Kardon’s exclusive Logic 7 Music mode for a

dramatic improvement in comparison to the

Dolby Pro Logic (I) mode of former times.

NOTE: Once a program has been encoded with

matrix surround information, it retains the sur-

round information as long as the program is

broadcast in stereo. Thus, movies with surround

sound may be decoded via any of the analog sur-

round modes such as Pro Logic II or IIx 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 broadcasts, radio dramas and music CDs

are also recorded in surround sound. You may

view a list of these programs at the

Dolby Laboratories Web site at www.dolby.com

Even when a program is not listed as carrying

intentional surround information, you may find

that the Dolby Pro Logic II or IIx Music, DTS

NEO:6 Music or Logic 7 Music or Enhanced

modes often deliver enveloping surround presen-

tations through the use of the natural surround

information present in all stereo recordings.

However, for stereo programs without any

surround information the 5/7CH Stereo modes

should be tried (effective particularly with old

”extreme” stereo recordings).And when you use

only two front channel speakers you should select

any of the Dolby Virtual Speaker surround modes,

delivering a virtually three dimensional sound

space with two speakers only.

Surround modes are selected using either the

front panel controls or the remote. To select a

new surround mode from the front panel, first

press the Surround Mode Button %S to

enter the Surround Modes Menu.Then use the

KL Buttons 5F to select the signal type

that you want to modify and confirm with the

OK Button to open the list of available Surround

Modes for this signal type.Again select the

desired Surround Mode and confirm with the OK

Button. Press the Back/Exit Button ^O to

exit the menu.

Note that the Dolby Digital or DTS modes may

nly be selected when a digital input is in use. In

addition, when a digital source is present, the

AVR will automatically select and switch to the

correct mode (Dolby Digital or DTS), regardless

of the mode that has been previously selected.

For more information on selecting digital sources,

see the following section of this manual.

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, external DVD-Audio or SACD player, or

another source device and carry them straight

through to the volume control.

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), select 2 CH Stereo in the

Surround Modes Menu

Digital Audio Signals

Digital audio signals offer the benefit of greater

capacity, which allows recording artists to

encode center and surround channel information

directly into the signal. The result is improved

sound quality and startling directionality, since

each of these channels is reproduced discretely.

Alternatively, the artist may encode only two

channels, but the digital signal allows for a

higher sampling rate that delivers greater detail.

High-resolution recordings usually sound

extraordinarily distortion-free at all frequencies,

but especially at high frequencies.

Multichannel digital recordings usually are found

in the 5.1-, 6.1- or 7.1-channel formats.The

channels included in a 5.1-channel recording are

front left, front right, center, surround left,

surround right and LFE. The LFE channel is

denoted as “.1” to represent the fact that it is

not full-range, being limited to the low

frequencies.

6.1-Channel recordings add a single surround

back channel, and 7.1-channel recordings add

surround back left and surround back right

channels to the 5.1-channel configuration. New

formats, such as Dolby TrueHD, Dolby Digital

Plus, DTS-HD and DTS-HD Master Audio, are

available in 7.1-channel configurations. The

AVR 355/AVR 255 is able to play the new audio

formats, delivering a more exciting home theater

experience.

NOTE: To use the 6.1- and 7.1-channel

surround modes, the AVR 355/AVR 255 must be

configured so that the Surround Back channels

are enabled. See the Manual Setup section on

page 24 for more information.

Digital formats include Dolby Digital 2.0 (two

hannels only), Dolby Digital 5.1, Dolby Digital

EX, Dolby Digital Plus, Dolby TrueHD, DTS-HD,

DTS-HD Master Audio, DTS 5.1, DTS-ES (6.1

Matrix and Discrete), DTS 96/24, 2-channel PCM

modes in 32kHz, 44.1kHz, 48kHz or 96kHz, and

5.1 or 7.1 multichannel PCM.

When a digital signal is received, the AVR 355/

AVR 255 detects the encoding method and the

number of channels. The number of channels

encoded will appear briefly in the front-panel

display as three numbers, separated by slashes

(e.g., “3/2/.1”).

The first number indicates the number of front

channels in the signal:

“1” represents a monophonic recording, usually

an older program that has been digitally

remastered or, more rarely, a modern

program for which the director has chosen a

special effect.

“2” indicates the presence of the left and right

channels, but no center channel.

“3” indicates that all three front channels (left,

right and center) are present.

The second number indicates whether any

surround channels are present:

“0” indicates that no surround information is

present.

“1” indicates that a matrixed surround signal is

present.

“2” indicates discrete left and right surround

channels.

“3” is used with DTS-ES bitstreams to represent

the presence of the discrete surround back

channel in addition to the side surround left

and right channels.

“4” is used with 7.1-channel digital formats,

including Dolby TrueHD, Dolby Digital Plus, DTS-

HD and DTS-HD Master Audio, to indicate the

presence of two discrete side surround channels

and two discrete back surround channels.

The third number is used for the LFE channel:

“0” indicates no LFE channel.

“.1” indicates that an LFE channel is present.

The 6.1-channel signals – Dolby Digital EX and

DTS-ES Matrix and Discrete – each include a flag

meant to signal the receiver to decode the

surround back channel.

For Dolby Digital EX materials, the incoming

bitstream will be displayed as 3/2/.1 EX-ON. For

older discs, the display may show EX-OFF, but

you will still be able to select the Dolby Digital

EX mode manually.
