Pacific Digital AVR 635 - Manual (Page 36)

36 OPERATION
Operation
• To set the output of the AVR so that the output
is “flat,” with the tone and balance controls de-
activated, press the Tone Mode button 8
h
once or twice so that the words Tone Out
appear momentarily in the Main Information
Display ˜. To return the tone controls to an
active condition, press the Tone Mode 8 but-
ton once or twice so that the words
Tone I n
momentarily appear in the Main Information
Display ˜.
• When the tone controls are active, the amount
of bass and treble boost/cut may be adjusted by
first pressing the Tone Mode Button on the
front panel 8 or the remote
h two or three
times until the desired setting ( BASS MODE or
TREBLE MODE ) appears in the on-screen dis-
play and the Lower Display Line ˜. Next, use
the
⁄ / ¤ Navigation Button E on the
remote or the ‹ / › Button on the front panel
7$ to change the setting as desired. The unit
will return to normal operation within five sec-
onds after the setting is changed.
• For private listening, plug the 6.3 mm stereo
phone plug from a pair of stereo headphones into
the front panel Headphone Jack 4.
Note that when the headphone’s plug is connect-
ed, 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 : B P , indicating that the head-
phone output is in the Bypass mode, and to con-
firm that no processing is being used.
• 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
M or
the Surround Mode Group Selector 5 to
cycle through the three Dolby Headphone modes
to select the one that you prefer.
Surround Mode Selection
One of the most important features of the
AVR is its ability to reproduce a full multichannel
surround sound field from digital sources, analog
matrix surround encoded programs and standard
stereo or even mono programs.
Selection of a surround mode is based on personal
taste, as well as the type of program source materi-
al being used. For example, CDs, motion pictures or
TV programs bearing the logo of one of the major
surround-encoding processes, such as Dolby
Surround should be played in either the Dolby Pro
Logic II Movie (with movies) or Music (with music)
surround mode, with any DTS NEO:6 mode or
with Harman Kardon´s exclusive Logic 7 Movie
Mode, to create a full range 5.1 channel or (with
Logic 7 and DTS NEO:6) even 7.1 channel sur-
round signal from surround encoded programs,
with a stereophonic left and right rear signal, just
as it was recorded (e.g. sound being recorded
from left rear side will be heard from that side
only, for more details see chart on page 33).
When no rear speakers are in use, the Dolby 3
Stereo mode should be selected with all surround
recordings.
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 (see also "Dolby Digital" on
page 36).
To create wide, enveloping sound field environ-
ments and defined pans and flyovers with all ana-
log 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 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 con-
ventional 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, Dolby Pro Logic IIx,
DTS NEO:6 Music or Logic 7 Music or Enhanced
modes often deliver enveloping surround presenta-
tions through the use of the natural surround infor-
mation present in all stereo recordings.
However, for stereo programs without any surround
information the Theater, Hall and 5/7CH Stereo
modes should be tried (effective particularly with
old ”extreme” stereo recordings) and for mono
programs, we suggest that you try the Theater or
Hall modes.
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 Group Selector Button
5 until the desired major surround mode group
such as Dolby, DTS or Logic 7 is selected. Next,
press the Surround Mode Selector Button 9
to choose the specific individual surround mode.
To select a surround mode using the remote con-
trol, press the button for the major surround
mode group that includes the mode you wish to
choose from: Dolby
M, DTS Surround N,
DTS Neo:6 T, Logic 7 O, Stereo S or
DSP Surround A. The first press of the button
will show the current mode from that group if it is
already in use, or the first available mode if you
are currently using another mode. To cycle
through the available modes in that group press
the button again until the desired mode appears
in the Lower Display Line ˜ and the on-
screen display.
To select from the DSP modes (Hall 1, Hall 2,
Theater) press the Surround Mode Selector
A repeatedly to scroll through the list of avail-
able modes.
Note that the Dolby Digital or DTS modes may
only 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 fol-
lowing 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), press the Stereo Button 5
S
until SURR OFF appears in the Main
Information Display ˜.
Digital Audio Playback
Digital audio is a major advancement over older
analog surround processing systems such as
Dolby Pro Logic. It delivers five or six discrete
channels: left front, center, right front, left
surround and right surround and with DTS ES (see
below) even surround back (with identical signals
for left and right). Each channel reproduces full
frequency range (20Hz to 20kHz) and offers
dramatically improved dynamic range and
significant improvements to signal-to-noise ratios.
In addition, digital systems have the capability to
deliver an additional channel that is specifically
devoted to low-frequency information. This is the
“.1” channel referred to when you see these
systems described as “5.1,” “6.1” or “7.1”. The
bass channel is separate from the other channels,
but since it is intentionally bandwidth-limited,
sound designers have given it that unique
designation.
Dolby Digital
Dolby Digital (originally known as AC-3
® ) is a
standard part of DVD, and is available on specially
encoded LD discs and satellite broadcasts and it is
a part of the new high-definition television
(HDTV) system.
Note that an optional, external RF demodulator is
required to use the AVR to listen to the Dolby
