THE SHURE HTS REFERENCE SYSTEM
A
number of Reference Systems can be constructed using
Shure HTS Theater Reference System Components. Please consult
with your Authorized HTS Dealer in order to determine which
Reference system best suits
your
specific needs. The system
described below is ideal for rooms of average size. It consists
of the following components:
1
Dolby Stereo Source
1
HTS5300 Acra-Vector Logic Decoder
3 HTSSOSPA Signal Processing Stereo Power Amplifiers
1
HTSSOCF Center Front Loudspeaker System
4
HTSSOLRS Loudspeakers
1
HTSSOSW Subwoofer Loudspeaker
1
Video display monitor or
'ITr
1
Switchable power strip with
6
(or more) sockets
HTS5300 ACRA-VECTOR LOGIC DECODER
The Shure HTS Acra-Vector Logic Decoder incorporates such
additional features as the Shure-designed Acoustic Space
Generator, true digital time delays that are user selectable for
individual room size and layout, input level and balance controls,
and a graphic readout of input signal strength at each channel.
These constituents significantly enhance the home listening
experience compared to rudimentary Surround processors. In
fact, the combination of Acra-Vector decoding with Shure's
Acoustic Space Generator provides, in a home space with front
left, right and center speakers, and only two surround speakers,
the same surround ambience that requires an array of eight to
ten speakers in a theater.
The Shure HTS Reference System also incorporates a
subwoofer loudspeaker for high-level low bass frequencies.
Because the film sound mixers use very low-frequency audio as
an integral part of the creation of mood and location, a
subwoofer reinforces the theater illusion and intensifies the
realism of the performance.
The HTS5300 is designed and built with meticulous attention
to detail and highest quality components used throughout. One
example of this philosophy of details is the use of gold-plated
input and output connectors on the Decoder itself and on the
supplied interconnecting cables.
HTSSOSPA SIGNAL PROCESSING AMPLIFIER
The HTSSOSPA amplifier has been designed to complement
the Shure HTS Decoder and Shure HTS Loudspeakers. The
HTSSOSPA amplifier has switch selectable Operational Modes in
each of which the amplifier response matches each HTS speaker
type.
For instance, in the LRS or CF modes, the amplifier output
is full range and precisely complements the HTSSOLRS or
HTSSOCF loudspeaker response respectively. On the other hand,
when Channel
1
is in Operational Mode SW, amplifier output
extends from 33 to 80 Hz to match the frequency response of
the HTSSOSW Subwoofer. In addition, to further enhance its
versatility,each channel of the HTSSOSPA amplifier also includes
a "Flat" output mode, making it suitable for use with any
loudspeaker.
In each channel, the HTSSOSPA includes a dynamically variabie
limiter that continuously measures the input signal and shapes
the response, depending on the Operational Mode selection, to
protect against distortion caused by overexcursion of the speaker
connected to that channel. An additional protection circuit
prevents long term hard clipping. The latter circuit can be
selectivelydisabled for each channel by pressing its Protection
Defeat switch.
In each of its HTS-speaker-correlatedoperational modes, the
wideband electronic response of the HTSSOSPA is tailored to
match the particular HTS loudspeaker system selected (HTSSOCF,
LRS, or SW). The design correlation between the amplifier
output and the loudspeaker/crossover interaction, loudspeaker-
to-room transfer function, and program-material-dependent
loudspeaker output at the listener position in a typical Home
Theater System has been achieved through extensive laboratory
testing and in situ program listening.
Consequently, the HTSSOSPA offers the user an amplifier that
is outstanding for high-quality audio/video theatrical
presentations in the home as well as one that provides a unique
experience in traditional multi-channel audio only listening.
Scrupulous care has been exercised in design and construction
of the HTSSOSPA with highest quality components used
throughout. Like the HTS5300, the HTSSOSI'A uses gold-plated
RCA phono jacks and additional gold-plated five-way binding
posts for loudspeaker output connectors.
HTSSOCF SPEAKER SYSTEM
The HTSSOCF Center Front speaker is compatible with the
HTSSOSPA power amplifier. In a top quality home theater sound
system, the loudspeaker used in the center front position is
subject to the most rigorous performance demands in terms of
power handling. The HTSSOCF meets those demands; its
performance has been carefully matched to the HTSSOLRS Front
Left and Right speakers in order to provide uniform response
across the front sound stage with realistic pans and unparalleled
fidelity.When the HTSSOSPA Amplifier is in the CF Operational
Mode, the amplifier and speaker cut off at 80 Hz for a perfect
match to the HTSSOSW Subwoofer; in the CFx Mode, the low-
frequency rolloff point extends down to 60 Hz.
