Introduction
Welcome to the Meridian DSP8000 Digital Loudspeaker System.
This user guide provides full information about using the DSP8000
loudspeakers in conjunction with your other equipment, to achieve the
superb results you can expect from them.

Introduction
Meridian DSP8000 loudspeaker system
The Meridian DSP8000 loudspeaker system represents
the fruits of more than 30 years of continuous
development of loudspeakers as musical instruments.
The finest materials and state-of-the-art design are
combined to create what we believe is the ultimate
home loudspeaker.
Digital Signal Processing
Digital Signal Processing, or DSP, is a technique
pioneered by Meridian in hi-fi products for achieving
extremely accurate reproduction of audio signals using
high-precision mathematical processing.
DSP allows sophisticated processing to be performed
without any of the cumulative noise or degradation
that inevitably occurs, even with high-quality analogue
circuitry. In addition, the signal improvement techniques
incorporated in the Meridian DSP loudspeakers would
be virtually impossible to implement in analogue
circuitry.
The Meridian DSP loudspeakers take advantage of
DSP for several different functions:
To remove timing variations from the incoming digital
•
signals (de-jittering).
To upsample 44.1kHz and 48kHz signals to 88.2kHz
•
and 96kHz.
To split the frequency band between bass, mid-
•
range, and treble drivers (crossover).
To perform filtering or adjustment of the frequency
•
response; eg treble or bass.
To provide volume control to 48-bit precision.
•
To perform electronic equalisation.
•
If you are using the Meridian DSP loudspeakers with a
digital source, such as CD or DVD, the signals remain
in digital form until the last possible stage.
DSP loudspeaker drivers
Each DSP8000 loudspeaker uses six multiple highefficiency long-throw custom bass drive units. The
bass units are mounted symmetrically in pairs on the
sides of the bass cabinet, cancelling vibration in order
to minimise interference with the mid-range and treble
units.
The treble and mid-range drivers are mounted in a
separate sealed head assembly. The treble unit is a
semi-horn-loaded composite dome design with a silver
voice coil. The mid-range unit incorporates a cone
made from a uniquely light and stiff combination of
polymers to give unparalleled transparency.
Power amplifiers
The speakers are driven by five independent highpower low-feedback power amplifiers mounted on a
multi-finned extruded heatsink. The combination of
idealised magnetic design, careful star earthing, and
very fast output devices gives the amplifiers extremely
low noise, high detail, and fast bass.
The whole electronic assembly is supplied from two
substantial toroidal transformers feeding high-quality
audiophile-grade capacitors.
Cabinet
Each DSP8000 loudspeaker is built around a precision
manufactured cabinet, which uses innovative design
techniques to give exceptionally low coloration and
amazing mid-range transparency.
The head assembly is a sealed enclosure fabricated
from curved pressure-laminated panels, each using
multiple layers of selected woods and metal to provide
high stiffness and damping. Its narrow tapered shape
offers optimum dispersion across a wide listening
area. It is supported on the bass enclosure by three
machined feet.
3
Introduction
Like the head unit, the bass cabinet is constructed
from interlaminated panels with extensive bracing. The
front panel is 6mm glass and incorporates a window for
the matrix display and infrared remote control sensor.
The cabinet stands on triangulated adjustable machined
foot assemblies with provision for floor spikes or skids.
Meridian High Resolution (MHR)
The DSP8000 loudspeakers support Meridian High
Resolution (MHR), to allow you to connect to other
MHR-compliant Meridian products to take advantage
of high-rate audio sources, and provide the additional
benefits of lower jitter and improved sound quality on all
sources.
MHR is a proprietary secure encoding format that uses
encryption and anti-copy methods to provide a secure
copyright protection environment, and allow the secure
transfer of audio streams within a Meridian-only system
for playback only.
Meridian Comms
The Meridian DSP loudspeakers are part of the
Meridian family of advanced digital, analogue, and video
components, and these incorporate a sophisticated
communications link, to allow you to control any
combination of units using a single remote, and ensure
that they will work together as a fully integrated system.
The communications system also allows you to extend
your hi-fi system into two or three rooms, with the
ability to control the sources in one room from the
controller in another room.
The following pages show two recommended
configurations based on the Meridian DSP8000
loudspeakers to illustrate the flexibility of Meridian
components.

Meridian Digital Theatre™
Up to seven Meridian DSP8000 loudspeakers can be
used in conjunction with a Meridian Surround Processor
to create a digital surround system with superb music
and cinema sound.
The Meridian DVD Player is an ideal source for use
with DSP loudspeakers. It allows you to play both audio
CDs and DVD movies, with the audio kept in digital
form until the last possible stage.

Unpacking
Before you begin installation you should ensure that
your DSP8000 loudspeakers are the correct voltage for
your local AC supply. If they are not, do not try to install
them, and contact your dealer.
You should not make any connections to the DSP8000
loudspeakers, or to any other component in your
system, while the AC power supply is connected and
switched on.
Care when unpacking
Take great care when unpacking or re-packing the
DSP8000 loudspeakers that you do not put undue
pressure on the side containing the drive units, as they
may be damaged if pressed.
Components
Each pair of DSP8000 loudspeakers is supplied with
the following components:
Caution
Meridian Audio has taken every care in the design,
assembly, finishing and packing of this product. The
high gloss finish on parts of the cabinet is achieved by
painting up to five coats of polyester lacquer onto the
plywood, each one hand polished.
Due to the product size and cabinet construction, small
marks on the lacquer surface may be visible when
unpacked. These small marks can usually be removed
as described in
It is the nature of all lacquer finishes to shrink over
time. This is unavoidable and may result in cabinet joint
lines becoming visible.
Meridian Audio has supplied products using lacquer
finishes for many years and we are confident that
when carefully used your product will return a lifetime’s
enjoyment.

If any of these items is missing, please contact your
dealer. We suggest that you retain the packaging
carefully, as it provides maximum protection in transit.
Unpacking
To unpack the DSP8000 loudspeakers please follow
the instructions on the accompanying leaflet.
Tightening the drive units
The DSP8000 loudspeakers typically take about two
weeks of normal use for the drive units to settle. It
is therefore recommended that you leave the grilles
unfitted during this period, and tighten the mounting
bolts on each drive unit every few days. Tighten the
bolts in symmetrically opposite pairs using the 3mm hex
wrench provided.
You should then check and if necessary retighten the
drive units every few years.
