DSP5200DS v1.2 20050707 RE
Each self-contained DSP5200 unit
combines a ‘2 1/2-way’ crossover
design, three custom drivers, three
amplifi ers, two multi-bit delta-sigma
digital converters, digital crossovers
and computers to deliver an impressive,
powerful and accurate sound with
full remote control over bass, treble
tilt, time-correct balance, absolute
phase, tweeter axis and input. The
latest technology gives the DSP5200
uncompromised, precise detail with
pinpoint imaging and dimensionality
in both stereo and surround. Advanced
signal processing packs dynamics and
bass into a size that defi es imagination.
DSP controls allow correction of the
frequency response in a variety of
locations.
Cabinet design
An enhanced basket design with sturdy
clamp rings delivers the very best
performance from the drivers, which
are chosen specifi cally for their sound.
The stylish, curved and tapered cabinet
both increases stiffness and improves
HF dispersion for a more natural top
end. Cabinet construction is of 19mm
thick multi-layer materials, with
proprietary heavy poured resin, and is
inherently stiff with superior geometry
and damping. The dual bass drivers
are 160mm long-throw composite
designs and the cabinet vents through
an extremely effective dual rear
port. This confi guration, along with
active operation and DSP correction,
delivers a combination of smooth,
powerful bass and very low mid-range
coloration. The tweeter is a 25mm
aluminium-dome, silver-wire design.
The DSP5200 is available in vertical
format in pairs or as a single vertical
centre loudspeaker. A horizontal
centre-channel version will follow later
in 2005.
Inside the DSP5200
Each speaker incorporates an
electronics panel in the rear part of the
cabinet. The speaker accepts digital
signals and has two inputs, placed at
the base of the cabinet for maximum
neatness and ease of installation.
The electronic design of the DSP5200
is entirely new, and takes advantage
of the latest advances in component
design as well as techniques and
approaches employed on the DSP8000.
The latest miniaturized surface-mount
components add control and improve
linearity, while the advanced high-value
capacitors allow the power supply and
its low-fi eld true toroidal transformer
to be placed closer to power amplifi ers,
offering lower inductance and
improved power performance.
The input receiver uses a FIFO (First
In First Out) memory buffer for the
lowest possible jitter from almost
any source. At the heart of the 5200
is a new DSP system based around a
150MIPS processor, running brand new
software. A built-in circuit monitoring
system handles both thermal and bass
protection, without compromising
either sound or protection capability.
High resolution double-precision
processing and upsampling, coupled
with the latest 192kHz, 24-bit DACs,
ensure that the digital signal path
offers true recording studio quality.
The three 75W amplifi ers are again
based on those in the DSP8000, with
the latest error-correcting auto-biasing
technology which runs the amplifi ers
with maximum linearity and minimal
distortion, even at high levels.
The bottom line
The result of all this intensive research
and careful, painstaking design is a
digital loudspeaker system that out-
performs anything of its size, while
its visual design and elegance remain
second-to-none.
Meridian products are carefully
designed inside and out and the
DSP5200 – available in a choice of black
or silver high gloss lacquer, satin Santos
rosewood, natural satin maple, satin
stained cherry and black ash fi nishes
– is intended to look as good as it
sounds.
And the sound is, quite simply,
remarkable.
