Input Setup
• THX Surround EX
“THX Surround EX - Dolby Digital Surround EX” is a joint
development of Dolby Laboratories and the THX division of
Lucasfilm Ltd.
In a movie theater, film soundtracks that have been encoded
with Dolby Digital Surround EX technology are able to
reproduce an extra channel which has been added during the
mixing of the program. This channel, called Surround Back,
places sounds behind the listener in addition to the currently
available front left, front center, front right, surround right,
surround left, and subwoofer channels.
This additional channel provides the opportunity for more
detailed imaging behind the listener and brings more depth,
spacious ambience, and sound localization than ever before.
When released to the home consumer market, movies that
were created using the Dolby Digital Surround EX
technology, may have a note to that effect on the packaging. A
list of movies created using this technology can be found on
the Dolby web site at http://www.dolby.com <http://
www.dolby.com> .
Only receiver and controller products bearing the THX
Surround EX logo, when in the THX Surround EX mode,
faithfully reproduce this new technology in the home.
This product may also engage the “THX Surround EX” mode
during the playback of 5.1 channel material that is not Dolby
Digital Surround EX encoded. In such case, the information
delivered to the Surround Back channel will be program
dependent and may or may not be very pleasing depending on
the particular soundtrack and the tastes of the individual
listener.
Listening Modes
Stereo
This mode has all input sound is output from the left and right front
speakers.
Direct
This mode delivers pure sound with minimum sound quality
adjustment and filtration. The sound recorded for the right and left
front channels is output to the right and left front speakers only and
not output to the subwoofer.
Mono Movie
This mode is suitable for playing back monaural recording such as
old movie soundtracks. The center channel delivers the
unprocessed original sound, whereas the other channels deliver the
center-channel sound processed with the appropriate
reverberation. This allows you to enjoy monaural sound with the
atmosphere of a movie theater.
THX
This mode is for playing back sources using THX.
This mode will work well with 5.1-channel Dolby Digital and
DTS sources and Dolby encoded sources.
For excellent fidelity when playing back THX sounds, it is
recommended to use a THX-certified speaker system.
• THX Cinema
This is the conventional 5.1-channel THX format. This mode
should be used only when playing back sources that were
mixed for playback in large movie theater environments.
DTS
This mode is for playing back DTS sources.
• DOLBY DIGITAL Surround,
DTS (Digital Theater System) Surround
This 5.1-channel digital surround format enables you to
individually record and play five full-range (20Hz–20kHz)
channels (left and right front, center, two surround channels)
plus an LFE channel (Low Frequency Effect) for the low-
range effect sound. It will create a realistic sound that could be
heard in the theaters and concert halls.
Dolby D (Dolby Digital)
This mode is for listening to sources encoded in the Dolby
Digital format.
Dialog normalization (Dialog Norm)
Dialog normalization is a feature of Dolby Digital. With this
function, for example, if “Dialog Norm: +4” is displayed while
playing back a Dolby Digital source, it means that that source
material was recorded 4 decibels higher than normal. Thus, by
lowering the volume by 4 decibels, it can be played back at the
same standard level for other sources. However, since most
source materials have been recorded at the same standard
level, you will rarely need to adjust the volume.
Surround modes
With this mode, decoding is performed automatically to match the
input signal. This original mode adds no sound processing to the
input signal.
• Pro Logic/3 Stereo (Dolby Pro Logoc/3 Stereo)
This mode is for playing back sources encoded using the
Dolby Pro Logic format. Select this listening mode when you
play a VHS, VHS hi-fi, LD, or DVD video that has the
mark.
This surround format consists of four channels (left, right,
center, and monaural surround) and emphasizes the center
channel. Dolby Pro Logic is very effective for panning music,
conversation, and three-dimensional sound movement output
from the three front channels. It also simulates the atmosphere
and surround effects of the sound reflected from the side and
rear walls of the theater.
If no surround speakers are connected, then the surround
sound is divided and output from the front left and right
channels (3 stereo).
