The relation between the selected surround mode and the input signal
The surround mode is selected with the surround mode buttons on SR7300/SR7300F/PS7300 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;

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.

more favorable aural characteristics.
DTS 96/24 allows for 5.1channel sound tracks to be encoded at a
rate of 96kHz/24bits on DVD-Video titles.
When DVD-video appeared, it became possible to deliver 24-bit, 96
kHz audio into the home, but only in two channels, and with serious
limitations on picture. This capability has had little use.
DVD-audio allows 96/24 in six channels, but a new player is needed,
and only analog outputs are provided, necessitating the use of the
D/A converters and analog electronics provided in the player.
DTS 96/24 offers the following:
1.Sound quality transparent to the original 96/24 master.
2.Full backward compatibility with all existing decoders. (Existing
decoders will output a 48 kHz signal)
3.No new player required: DTS 96/24 can be carried on DVD-video,
or in the video zone of DVD-audio, accessible to all DVD players.
4.96/24 5.1-channel sound with full-quality full-motion video, for
music programs and motion picture soundtracks on DVD-video.
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.

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.

The stereo CD is a 16-bit medium with sampling at 44.1 kHz. Professional audio has been 20- or 24-bit for some time, and there is
increasing interest in higher sampling rates both for recording and
for delivery into the home. Greater bit depths provide extended
dynamic range. Higher sampling rates allow wider frequency
response and the use of anti-alias and reconstruction fi lters with

With the following procedure, the Tracking Point, which is necessary for the adjustment and measurement of the tuner, can
be memorized.
1. Turn on the unit, press DVD, TUNER and 7.1ch - IN key simultaneously more than three seconds.
2. "FACTORY MODE" will be displayed on the FLD for two seconds and the following frequencies will be stored in the
Preset Memory.

Microprocessor (CPU), DSP Version and FLD Segment Check Mode
Turn the unit into the Factory Mode (See above) fi rst. Each time V-OFF button on the Remote controller is pressed or RC-5
code 161302 (Display) is entered, information shown on the FLD changes in the following order. Software versions of µ-com
and DSP can be seen and FLD segments can be checked.

Preset
Note : Step4, 5 is to check if CPU software is capable of DSP code. "Software Type No" is to show what "DSP Code Group"
CPU is capable of. And vice versa.
Step 8 is to manage the 16 codes for DSP.
• When the unit is once turned into Factory Mode, the unit keeps this mode until the main power is turned off.
(Turning into stand-by mode does not make it quit from Factory Mode.) When the unit quits from Factory Mode,
Information in the memory is also cleared and the unit returns to the status when it is out from the factory.
Product Reset
To reset the back up memory of the unit into the default status, follow the procedure below.
1. Turn of the unit and press SELECT and ATT keys simultaneously more than 1.5 seconds.
2. After "DEFAULT" is displayed on FLD, power is turned off once and turned of again, EEPROM is cleared to the default
status, µ-com is reset and the unit returns to the normal status. (Software Serial Number will not be cleared.)
Note : When the unit is shipped from the factory, the procedure above must be done to set the unit to initial status after the
