Introduction
Surround System
Since the TX-DS555 is equipped with front, center, and Surround
amplifiers, you can produce Dolby Digital, Dolby Pro Logic, Hall,
Live, Arena, and Studio Surround effects. You can enjoy the feeling
of a movie theater or concert hall in your own living room.
Dolby Digital
Dolby Digital is a new-generation digital audio format for multichannel Surround audio. With this digital audio format, you can
create a five full-range channel system that is a developed version
of the conventional Surround system (left, center, right, and Surround channel).
Adding to its five full-range channels, Dolby Digital supports an
LFE (low frequency effect) channel, which is used solely for low
frequency sounds independent of the other channels.
Dolby Digital is sometimes referred to as a “5.1” channel format
since this LFE channel is indicated as 0.1.
This fully discrete 5.1 channel Dolby Digital can reproduce the
sound of a wide and dynamic range, transforming your room into a
home theater.
Dolby Digital technology is implemented in such media as laser
discs, DVDs (digital video discs), CATV (cable television), DBS
(direct broadcasting satellite).
By using CATV or the proper equipment for the playback of laser
discs bearing the
trademark, you can recreate in your own
living room the feeling of watching a movie in a top-quality theater.

DSP (Digital Signal Processor)
The DSP converts the musical signal into digital form and produces
reflected sound from the digital signal. This is applied to the musical signal to yield an effect approaching that of a live performance.

DOLBY PRO LOGIC Surround
Many motion pictures have been released in 4-channel “Dolby Stereo” sound, with music, dialogue, and panned effects coming from
the 3-channel front soundstage, and surround effects and ambience
emanating from the sides and rear of the theater.
The motion picture masters are used for production of stereo VHS,
VHS-Hi-Fi, Beta Hi-Fi, and stereo laser discs that you can buy or
rent at your video store. The TX-DS555 incorporates the Digital
Dolby Pro Logic Surround Circuit, which is designed to decode the
four-channel audience experience found in DOLBY STEREO
movies. Dolby Pro Logic Surround is capable of recreating a multidimensional soundstage, but with the increased channel separation
it gives a far greater sense of “movement” and sound localization.
Just like in the theater, the addition of the active center channel
ensures that all audience members hear dialogue coming from its
on-screen sources, regardless of seating position.
HALL Surround
This mode is especially suitable for media that already has a substantial amount of reverb sound, such as classical music, since it
simulates the atmosphere of a concert hall.
LIVE Surround
This mode reproduces the feeling of a live performance.
ARENA Surround
This mode recreates the mood of listening to a concert in a domed
stadium.
STUDIO Surround
This mode is good for studio recordings that may have few reverb
sounds such as pop and jazz.



reverberations contained in the original recording. These are
converted into reflected sound that is reproduced from four
directions. Thus, in some cases an unnatural impression can be
conveyed if there are too few reflections in the recording or if
the effects in the original recording were produced artificially.
The concert hall effect is not merely an artificial reverberation
unit, but a sophisticated effect that spreads existing reverberation around.

Multi-Room Remote System (

Making speaker connections
Positioning speakers
Speaker placement plays an important role in the reproduction of Surround sound. The placement of the speakers varies
depending on the size of the room and the wall coverings
used in the room. The illustration shows an example of a layout for standard speaker placement. Refer to this example
when you position the speakers in order to experience the
best of Surround sound.

Center
speaker

For ideal Surround effects, all speakers should be installed. If
a center speaker or subwoofer is not connected, the sound
from the unused channel is properly distributed to the connected speakers in order to produce the best Surround sound
possible.
Front: The left, right, and center speakers should face the
seated listener and be placed at ear level. The center speaker
produces a richer sound image by enhancing the perception
of the sound’s source and movement.
Surround: Place the left and right Surround speakers
1 meter (3 feet) above the listener’s ear level and toward the
sides of the room, making sure that the listener is within the
speakers’ dispersion angle. These speakers produce the feel
of a moving sound while creating the sensation of being in
the middle of the action.
Subwoofer: Install a subwoofer with a built-in power amplifier for powerful bass sounds. The placement of the subwoofer does not affect the final quality of the sound image
too much, so you can install it with the room layout in mind.
