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.

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.

Setting up

the DSP8000

loudspeakers

To dismantle the loudspeakers

It is advisable to remove the head units when moving
the speakers. This is achieved by disconnecting the
head lead from the head unit and lifting off the head.
Take care while the head is not in position as this
exposes its mounting spikes. While not in place the
head should be stored safely but care should also be
taken of the surface they are placed upon as it may be
damaged by the cups.

When dismantling the speakers always disconnect and
switch off the power first.

Note: Do not disconnect the head lead while
the unit is connected to the AC supply and
switched on.

10

Setting up

the DSP8000

loudspeakers

Positioning the DSP8000 loudspeakers

To obtain the best sound

For best results adjust the position of the loudspeakers
while listening to music.

If possible, have the most acoustically absorbent wall
in the room behind the front speakers. Ideally have
each DSP8000 loudspeaker at least 0.5m (20") from
a corner, and position them approximately 0.25m (10")
from the wall.

If you are using a DSP8000 loudspeaker as a centre
channel, place the speaker centrally between the main
left-right pair and, if possible, arrange for the treble
units of the three speakers to be approximately the
same height.

18

Using the DSP8000

loudspeakers

Selecting a source

When not playing, the DSP8000 loudspeakers should
be left in the standby state. This uses a negligible
amount of electricity, but ensures that the components
of the loudspeakers operate at maximum efficiency
from the moment you start.

If you are not going to use the DSP8000 loudspeakers
for several days you should switch each unit completely
off at the back panel, and disconnect it from the AC
power supply.

To select a source

Press the appropriate source key on the remote; eg

•

Radio.

This will bring the DSP8000 loudspeakers out of
standby, and the displays will show the currently
selected source and volume setting.

For example:

 Radio65

To switch to standby

Press Off on the remote.

•

The loudspeakers will switch to standby.

The displays will show:

    .

Initially all the sources are set to use the RJ45 digital
input. To configure all sources to use the co-axial input,
configure the speaker as M.Coax or S.Coax; see

Using the DSP8000

loudspeakers

Adjusting the volume

The DSP8000 loudspeakers adjust the volume in
precise steps of 1dB, where 9dB is equivalent to
doubling the loudness, and can be varied in the range
1 to 99dB.

When you first connect power to the DSP8000
loudspeakers the volume is set to 65, which is similar
to the midway position of the rotary volume control on a
conventional preamplifier.

To change the volume

Press the A or V volume keys on the remote.

•

As you adjust the volume setting the display
will show the current volume level.

For example:

To mute the sound

Press Mute on the remote.

•

Radio55

The display will show:

 Muted

To restore the sound

Press Mute again on the remote.

•

Alternatively, the sound will be restored if you adjust the
volume.

21

Using the DSP8000

loudspeakers

Changing the treble, bass, or phase

The DSP loudspeakers provide sophisticated treble and
bass controls, to allow you to adjust the broad balance
of the system to correct for the acoustics of your
listening room, or for a misbalanced recording.

The controls are more subtle than conventional
tone controls, and take advantage of digital signal
processing techniques to provide a more natural
adjustment of the frequency response.

You can also change the absolute phase of the signal,
to compensate for signals which are out of phase,
giving an unnatural-sounding bass.

If you have a Meridian Surround Controller these
functions are performed via the surround controller.

To change the treble

Press Function < or Function > until the display

•

shows the current treble.

The bass control allows you to adjust the bass
response in the room by ±5dB in 0.5dB steps.
Normally settings between +3.0 and -2.0 will give the
most natural results.

To change the absolute phase

Press Function < or Function > until the display

•

shows the current phase.

For example:

Press Function A or Function V to change the

•

phase.

 Phase+

For example:

Press Function A or Function V to change the

•

treble.

The treble control tilts the frequency of the response
over the entire frequency range to make the sound
brighter or dimmer. It can be adjusted between ±10db
in 0.5dB steps. Normally settings between +1.0 and

-2.0 will give the most natural results.

 Tre.+0.0

To change the bass

Press Function < or Function > until the display

•

shows the current bass setting.

For example:

Press Function A or Function V to change the

•

bass.

 Bass+0.0

22

Using the DSP8000

loudspeakers

Changing the listening position

The balance control of the DSP8000 loudspeakers
uses digital signal processing to compensate for an
off-centre listening position by delaying and diminishing
the sound in one speaker, thus effectively shifting the
speaker’s image back.

The axis control allows you to adjust the optimum
listening height of the DSP8000 loudspeakers, like a
balance control operating in the vertical plane.

If you have a Meridian Surround Controller these
functions are performed via the surround controller.

To change the balance

Press Function < or Function > on the remote

•

until the display shows the current balance.

For example:

Press Function A or Function V to change the

•

balance.

 Bal.<0>

The axis can be adjusted between 3 and -2, where

Configuring the DSP8000
loudspeakers

This chapter explains how to configure the DSP8000 loudspeakers to
suit the other equipment in your system.

The first stage in configuring the DSP8000 loudspeakers is to choose
one of the standard settings, and these are designed to set all of the
parameters to their most common values. You can also configure each
setting individually for applications not catered for by one of the standard
settings.

Configuring

the DSP8000

loudspeakers

Once you have configured the DSP8000 loudspeakers you will probably
never need to change the configuration, unless you alter the equipment
connected to your system at a later stage.

the DSP8000

loudspeakers

Choosing standard settings

The DSP8000 loudspeakers provide the following
five alternative standard settings, called Types, which
configure all aspects of the loudspeaker into the most
commonly needed configurations:

Type Description

1 Standard setting for 2-channel system.

5 For use with a Meridian CD player (eg 808.2)

connected to the RJ45 SpeakerLink input; all
other sources use the co-axial input.

6 For use with a Meridian Surround Controller.

7 For use in a second room.

8 For use in the second or third room of a three-

Types 2, 3, and 4 are for compatibility with 200/600
series units.

In all cases except Type 5, the co-axial input is used for
all sources.

Choosing one of the standard settings overrides any
other configuration you may have performed, and so
can be used to reset the configuration of the speakers.

To select a standard setting

Switch off the DSP loudspeaker.

•

Turn on the power again while holding down the

•

number key on the remote which corresponds to the
Type you want to use.

The display will show the Type number.

For example:

You can configure the operation of the DSP
loudspeakers to suit the way your system is set up, and
the way in which you want to use it.

These settings are configured automatically to
appropriate values when you choose one of the
standard Type settings, and you should not normally
need to alter them; see

Configuring the sources

The DSP loudspeakers provide 12 sources
corresponding to the 12 source selection keys on the
remote:

CD, RADIO, DVD, AUX, DISC, TAPE, TV,
CABLE, SAT, VCR1, VCR2, and GAME.

When the master DSP loudspeaker is set to one of
the standard Types, the source selection keys select
the co-axial input (apart from Type 5 which assigns
the CD source to the RJ45 SpeakerLink input). See

Choosing standard settings

If the configuration you want is not catered for by
one of the standard settings, you can configure each
source individually.

For each source you can configure:

The label used for it on the front panel display, from a

•

range of alternative labels.
The digital input it selects.

•

The comms type and address, to control other

•

Meridian 500 Series equipment.
Other advanced options.

You only need to configure the sources on the DSP
loudspeaker you have specified as the master.

There is radio interference

The DSP8000 loudspeaker is a digital audio and
computing device which has been designed to very
high standards of electromagnetic compatibility.

If this equipment does cause or suffer from interference
to/from radio or television reception then the following
measures should be tried:

Reorient the receiving aerial (or antenna) or route the

•

antenna cable of the receiver as far as possible from
the DSP8000 loudspeaker and its cabling.
Ensure that the receiver uses well-screened antenna

•

cable.
Relocate the receiver with respect to the DSP8000

outlets.
If the problem persists contact your dealer.

Unit goes silent when played hard and
displays ‘Hot’

The DSP8000 loudspeakers have a temperature

sensing system on board, which prevents overheating
of the electronics. The sound will continue when the
speaker has cooled.

The green indicator flashes or stays on

This indicates that the DSP is protecting the
loudspeaker drive units from overheating. It is normal
for this light to stay on after a long period of listening at
high sound levels.

Troubleshooting

Maintenance and cleaning

Fitting and removing the grilles

When fitting the grilles ensure that the two cutouts are
at the 3 o‘clock and 9 o‘clock positions, as this will
align the pattern on the grille fabric correctly.

To remove the grilles grasp the grille by the two cutouts
and pull gently away from the loudspeaker.

Cleaning

Small marks on the lacquer surface can usually be
removed with a damp cloth.

Deeper scratches can be removed by treating with
additional polyester lacquer filler and then polishing
carefully. Consult your authorised Meridian dealer for
advice before attempting any repair.
