INTRODUCTION
Meridian DSP8000 loudspeaker system
The Meridian DSP8000 loudspeaker system represents the fruits of more than 25 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 highquality 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 provide digital protection of the loudspeakers against high-level lowfrequency 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 high-efficiency 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.
2
INTRODUCTION
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 high-power 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 pressurelaminated 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 anticopy methods to provide a secure copyright protection environment, and allow the secure transfer of audio streams within a Meridian-only system for playback only.

INTRODUCTION
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 page shows two recommended configurations based on the
Meridian DSP8000 loudspeakers to illustrate the flexibility of Meridian components.

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.
• Grilles packed separately.
• Six foot-mounting plates, spike clamps, spikes, and spike protectors.
• Four stabilisers.
• A hex wrench (3mm) for the drive units.
• A 10mm spanner for removing the headboard and footboard.
• Six shouldered spikes for the head unit.
• Meridian System Remote, battery and user guide.
• One power cord per speaker suitable for your territory.

LOUDSPEAKERS
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 high technology 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 36.
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 the power off first.
Note: Do not disconnect the head lead while the unit is connected to the AC supply and switched on.

Positioning the DSP8000 loudspeakers
Safety warnings
• Do not expose the speakers to dripping or splashing.
• Do not place any object filled with liquid, such as a vase or plant pot, on the speakers.
• Do not place naked flame sources, such as lighted candles, on the speakers.
To avoid overheating
Do not position the speakers:
• In direct sunlight.
• Near heat sources, such as a radiator.
• Directly on top of heat producing equipment.
The back panel of the DSP8000 loudspeaker acts as a heatsink and requires adequate ventilation. Ensure that air can flow around it.
The heatsink normally runs warm to the touch when the speakers are not in standby.
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.

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
By default the 12 sources shown below are available.
As standard, all the sources are set to select the D1 digital input. To select

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 red A or V keys on the remote.
As you adjust the volume setting the display will show the current volume level:
To mute the sound
• Press Mute on the remote.

The display will show:
To restore the sound
• Press Mute again on the remote.
Alternatively, the sound will be restored if you adjust the volume.
22
USING THE DSP8000
LOUDSPEAKERS
Changing the tilt, bass or phase
The DSP loudspeakers provide sophisticated tilt 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.
To change the tilt
• Press < or > until the display shows the current tilt.
For example:
Tilt+0.0
• Press A or V to change the tilt.
The tilt 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 < or > until the display shows the current bass setting.
For example:
Bass+0.0
• Press A or V to change the bass.
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 > or < until the display shows the current phase.
For example:
Phase +
• Press A or V to change the phase.
23
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.
To change the balance
• Press < or > on the remote until the display shows the current balance.
For example:
Bal. <0>
• Press A or V to change the balance.
The display shows the direction and position of the listening position.
For example:
Bal. 12>
There are 32 steps in each direction.
To change the axis
• Press < or > on the remote until the display shows the current axis setting.
For example:
Axis -1
• Press A or V to change the axis.
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 restore flat settings
• Press Clear on the remote.
The display shows:
Reset
This restores the balance, axis, tilt, and bass to zero.

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.

Configuring the sources
When the master DSP8000 loudspeaker is set to one of the standard Types the 12 source selection keys on the remote select inputs D1 and D2 as shown in the table on page␣ 30.
If the configuration you want is not catered for by one of the standard settings, you can configure each source individually.
The DSP loudspeakers provide 12 sources corresponding to the 12 source selection keys on the remote:
CD, Radio, LP, TV, Tape1, Tape2, CDR, Cable, DVD, VCR1, VCR2, and
LD.
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 identify 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.
To configure a source
While in configuration mode:
• Press the source key on the remote corresponding to the source you want to configure.
For example, to configure the Radio source the display initially shows:
• Press > or < to step between options.
RD Radio
The right-hand set of characters shows the current value of the option.
• Press A or V to change the value of the option.
When you have finished programming sources:
• Switch off at the back panel, and then switch on again to restore normal operation.

Troubleshooting
Display on front panel not lit
Check the following:
• There is AC power connected to the socket on the back of the DSP8000 loudspeaker.
• The power switch on the back panel of the DSP8000 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.
Remote not working
Check the following:
• The battery in the Meridian System Remote.
• See if the DSP8000 loudspeaker has been set up as not controller in the
Unit goes silent when played hard
• 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.
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.

TROUBLESHOOTING
Drive units move when the speaker is switched on or off
• This is normal as the speaker active electronics settle.
Configuring the DSP8000 loudspeaker does not have any effect
Make sure that you are configuring the DSP8000 loudspeaker used as the master digital loudspeaker in the system. This determines the configuration of all digital loudspeakers in the system.
Unit stays in standby
• Check that it is connected correctly.
• Turn the system on from another Meridian product in the system.
Only the master loudspeaker plays
• Check the S5 cables are connected correctly.
Sound is odd or mono
• Check that the DSP8000 loudspeakers are correctly configured as Left and Right respectively.
The yellow indicator flashes or stays on
This indicates that DSP clipping is occurring.
Brief flashes indicate occasional clipping which will not be audible.
If the indicator stays on for long periods this may indicate a fault in the configuration of your system, and you should contact your Meridian dealer.

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 by treating with
Black Turtle Wax Color Magic.
Do not use any coarse polish such as Auto Colour Restorer, and always test any polish on a non-visible area first. Do not use any polish containing a solvent; these can cause crazing of the surface.
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.
