CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC
cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product and
controls and chassis bottom.
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and
verifi ed before it is return to the user/customer.

The relation between the selected surround mode and the input signal

The surround mode is selected with the surround mode buttons on SR4400 or the remote control unit. However, the sound

you hear is subject to the relationship between the selected surround mode and input signal. That relationship is as follows;

2. TECHNICAL DESCRIPTION

DTS was introduced in 1994 to provide 5.1 channels of discrete
digital audio into home theater systems.
DTS brings you premium quality discrete multi-channel digital sound
to both movies and music.
DTS is a multi-channel sound system designed to create full range
digital sound reproduction.
The no compromise DTS digital process sets the standard of quality
for cinema sound by delivering an exact copy of the studio master
recordings to neighborhood and home theaters.
Now, every moviegoer can hear the sound exactly as the movie­maker intended.
DTS can be enjoyed in the home for either movies or music on of
DVD’s, LD’s, and CD’s.
“DTS” and “DTS Digital Surround” are registered trademarks of Digi­tal Theater Systems, Inc.

The advantages of discrete multichannel systems over matrix are
well known.
But even in homes equipped for discrete multichannel, there
remains a need for high-quality matrix decoding. This is because of
the large library of matrix surround motion pictures available on disc
and on VHS tape; and analog television broadcasts.
The typical matrix decoder of today derives a center channel and
a mono surround channel from two-channel matrix stereo material.
It is better than a simple matrix in that it includes steering logic to
improve separation, but because of its mono, band-limited surround
it can be disappointing to users accustomed to discrete multichan­nel.
Neo 6 offers several important improvements as follow,
. Neo 6 provides up to six full-band channels of matrix decoding
from stereo matrix material. Users with 6.1 and 5.1 systems will
derive six and fi ve separate channels, respectively, corresponding to
the standard home-theater speaker layouts.
. Neo 6 technology allows various sound elements within a channel
or channels to be steered separately, and in a way which follows
naturally from the original presentation.
. Neo 6 offers a music mode to expand stereo nonmatrix recordings
into the fi ve- or six-channel layout, in a way which does not diminish
the subtlety and integrity of the original stereo recording.

DTS-ES Extended Surround is a new multi-channel digital signal
format developed by Digital Theater Systems Inc. While offering high
compatibility with the conventional DTS Digital Surround format,
DTSES Extended Surround greatly improves the 360-degree sur­round impression and space expression thanks to further expanded
surround signals. This format has been used professionally in movie
theaters since 1999.
In addition to the 5.1 surround channels (FL, FR, C, SL, SR and
LFE), DTS-ES Extended Surround also offers the SB (Surround
Back) channel for surround playback with a total of 6.1 channels.
DTS-ES Extended Surround includes two signal formats with differ­ent surround signal recording methods, as DTS-ES Discrete 6.1 and
DTSES Matrix 6.1.
“DTS”, “DTS-ES Extended Surround” and “Neo:6” are trademarks of
Digital Theater Systems, Inc.

Dolby Digital identifi es the use of Dolby Digital (AC-3) audio coding
for such consumer formats as DVD and DTV. As with fi lm sound,
Dolby Digital can provide up to fi ve full-range channels for left,
center, and right screen channels, independent left and right sur­round channels, and a sixth ( “.1”) channel for low-frequency effects.
Dolby Surround Pro Logic II is an improved matrix decoding tech­nology that provides better spatiality and directionality on Dolby Sur­round program material; provides a convincing three-dimensional
soundfi eld on conventional stereo music recordings; and is ideally
suited to bring the surround experience to automotive sound. While
conventional surround programming is fully compatible with Dolby
Surround Pro Logic II decoders, soundtracks will be able to be
encoded specifi cally to take full advantage of Pro Logic II playback,
including separate left and right surround channels. (Such material
is also compatible with conventional Pro Logic decoders.)
Dolby Digital EX creates six full-bandwidth output channels from

5.1- channel sources. This is done using a matrix decoder that
derives three surround channels from the two in the original record­ing. For best results, Dolby Digital EX should be used with movies
soundtracks recorded with Dolby Digital Surround EX.
Manufactured under license from Dolby Laboratories. “Dolby”, “Pro
Logic”, and the double-D symbol are trademarks of Dolby Laborato­ries.

Circle Surround II (CS-II) is a powerful and versatile multi-channel
technology. CS-II is designed to enable up to 6.1 multi-channel sur­round sound playback from mono, stereo, CS encoded sources and
other matrix encoded sources. In all cases the decoder extends
it into 6 channels of surround audio and a LFE/subwoofer signal.
The CS-II decoder creates a listening environment that places the
listener “inside” music performances and dramatically improves both
hi-fi audio conventional surround-encoded video material. CS-II
provides composite stereo rear channels to greatly improve separa­tion and image positioning adding a heightened sense of realism
to both audio and A/V productions.
CS-II is packed with other useful feature like dialog clarity (SRS
Dialog) for movies and cinema-like bass enrichment (TruBass).
CS-II can enable the dialog to become clearer and more discern­able in movies and it enables the bass frequencies contained in
the original programming to more closely achieve low frequencies
overcoming the low frequency limitations of the speakers by full
octave.
