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 split the frequency band between bass, midrange, 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 provide digital protection of the loudspeakers against high-level low-frequency transients.
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.
The Special Edition model uses variations of the mid and bass units fitted with solid metal rings that clamp the drivers more firmly in the cabinet. It uses a similar treble unit but with a lighter, more rigid, beryllium dome. This combination allows the Special Edition loudspeakers to have a more controlled transient response across a wider frequency range.
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.
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.

Setting up the DSP8000 loudspeakers
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:
•
•
•
•
•
•
The DSP8000 loudspeakers.
A hex wrench (3mm) for the drive units.
A 10mm spanner for removing the headboard.
Six shouldered spikes for the head unit.
One power cord per speaker suitable for your territory.
This user guide.
If any of these items are 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.
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 Maintenance and cleaning, page 31.
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.
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.
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.

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.

Auto configuration
In a system of Meridian products one of the products acts as the controller for the system. It receives infra-red commands from the MSR+ and then, if appropriate, relays them to the other products in the system via the Comms link.
The following automatic setup procedure should be used to set up the Comms correctly between several products:
• Switch all the units to standby.
• Press Clear on the MSR+ remote.
Each unit will display: Auto
One unit will then be designated as the controller.
The display shows:
Con
All the other units will be configured as non-controllers.
The displays show:
N.Con
If for any reason the automatic setup does not work, make sure you are operating the remote from a position where all the units can receive the infra-red, and try again.
If this fails:
• Restore the default operation by selecting one of the standard types; see To select a standard setting, page 24.

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
Initially all the sources are set to use the SpeakerLink digital input. To configure all sources to use the co-axial input, configure the speaker as M.Coax
or S.Coax
; see To choose Master or Slave and the primary connector, page 24. To configure an individual source to use a different input see To configure a source, page
28.
To switch to standby
• Press Off on the remote.
The loudspeakers will switch to standby.
The displays will show:

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:
Radio 55
To mute the sound
• Press Mute on the remote.
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.
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.
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: Phase +
• Press Function A or Function V to change the phase.
To change the treble
• Press Function < or Function > until the display shows the current treble.
For example:
Tre.+0.0
• 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.
To change the bass
• Press Function < or Function > until the display shows the current bass setting.
For example:
Bass+0.0
• Press Function A or Function V to change the bass.
21
Using the DSP8000 loudspeakers
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.
The axis can be adjusted between 3 and -2, where
0 corresponds to the axis of the treble unit. Usually a listener will be below that position, so we recommend settings of -1 or -2.
To change the balance
• Press Function < or Function > on the remote until the display shows the current balance.
For example:
Bal. <0>
• Press Function A or Function V to change the balance.
The display shows the direction and position of the listening position.
For example:
Bal. 12>
There are 30 steps in each direction.
To change the axis
• Press Function < or Function > on the remote until the display shows the current axis setting.
For example:
Axis -1
• Press Function A or Function V to change the axis.
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.
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.
23

Types 2, 3, and 4 are for compatibility with 200/600 series units.
In all cases except Type 5 the SpeakerLink 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:
Type 1
To choose Master or Slave and the primary connector
You should select one loudspeaker to be the Master; this will normally be the centre channel. For more information see Connecting to other equipment, page
12. Each other DSP loudspeaker should be configured as a Slave.
• Press the > (Play) key on the remote.
• For each speaker this steps between the following four options:
Option
M.RJ45
M.Coax
S.RJ45
S.Coax
Master/Slave

Initially all sources will be configured to use the primary input you have specified, but you can configure individual sources to use the other input; see To configure a source, page 28.
For example, to define the left speaker as a Slave using the digital co-axial connectors:
The display shows:
L.S.Coax
When you have configured the loudspeaker:
• Switch off the DSP loudspeaker, using the power switch on the back, and then switch on again to restore normal operation.

Specifying information about your system
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 To select a standard setting, page 24.
To configure the DSP loudspeaker
• Turn off the DSP loudspeaker, using the power switch on the back panel.
• Turn on the power again while holding down the 0 key on the remote.
The display will show the current setting of the first configuration option.
For example:
L.M.RJ45
• Press > or < to step between the options.
• Press A or V to change the value of the current option.
The following table shows the options you can configure:

† SL (SpeakerLink) allows the setting to be controlled by a suitable controller, such as the 861 Reference
Digital Surround Controller, via the SpeakerLink connection.
To specify the loudspeaker position
The frequency response of each loudspeaker can be individually tailored to compensate for its position in the room, or to integrate the sound with a subwoofer where no surround controller is present.
For multichannel systems with a surround controller we recommend each speaker is configured individually.
For two-channel systems you may wish to set this control to SL in both speakers so that it can be adjusted remotely by the system controller (eg a
Meridian 818).
When configuring the DSP8000 loudspeakers, point the remote at the speakers, even if you have a
Meridian Surround Controller.
• Press > or < until the display shows the current position setting.
For example:
Pos.Free
Option What it means
Pos.Corn
Speaker closer than
0.5m (20") to a corner.
Pos. SL Frequency response controlled via
SpeakerLink.
To specify the ambient temperature for thermal protection
The DSP8000 drive units are protected from overheating by thermal protection software. This is already configured correctly for most domestic listening environments, but if the ambient temperature is greater than 24°C (75°F) you should adjust the ambient temperature setting.
• Press > or < until the display shows the current ambient temperature setting.
For example: Temp 24
• Press A or V to specify the ambient temperature.
When thermal protection is active the lower left green indicator will be illuminated.
• Press A or V to select the appropriate option as follows:
Option What it means
Pos.Free
Flat frequency response.
Pos.Wall
Speaker closer than
0.5m (20") to a wall.
Pos.Sub1
Applies a secondorder high-pass filter at 80Hz for use with a subwoofer.
Pos.Sub2
Applies a second-order high-pass filter at
120Hz for use with a subwoofer

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 .
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 equipment.
Other advanced options.
You only need to configure the sources on the DSP loudspeaker you have specified as the Master.

Troubleshooting
Display on front panel not lit
•
•
•
Check the display mode by pressing DISPLAY on the
MSR+.
Check there is AC power connected to the socket on the back of the DSP loudspeaker.
Check the power switch on the back panel of the
DSP loudspeaker is turned on.
If the display will still not illuminate, check any fuses in your power supply and the fuse in the inlet of the
DSP8000 loudspeaker. If these are all intact, contact your dealer.
Unit stays in standby
•
•
Check that it is connected correctly.
Turn the system on from another Meridian product in the system.
Remote not working
•
•
Check the battery in the MSR+ remote.
See if the DSP8000 loudspeaker has been set up as not controller in the Meridian Configuration program; see To configure the DSP loudspeaker, page 26.
Note that this may be deliberate by your dealer.
Configuring the DSP8000 loudspeaker does not have any effect
•
•
For source selection issues make sure that you are configuring the DSP loudspeaker used as the Master loudspeaker.
For settings that can be controlled by SpeakerLink
(eg position) you must specifically configure every loudspeaker, not just the Master.
Drive units move when the speaker is switched on or off
• This is normal as the speaker active electronics settle.
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 loudspeaker.
Connect the receiver and this product to different AC outlets.
If the problem persists contact your dealer.
Only the Master loudspeaker plays
• Check the cables are connected correctly.
Sound is odd or mono
• Check that the DSP8000 loudspeakers are correctly configured as Left and Right respectively.
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.
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.
