Introduction

Welcome to the Meridian DSP loudspeaker range.

This user guide provides full information about using DSP loudspeakers in conjunction with your other equipment, to achieve the superb results you can expect from them.

Introduction

Meridian DSP loudspeakers

Meridian DSP loudspeakers represent 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 range of home loudspeakers.

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 the analogue domain.

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 audio 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 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 DSP loudspeaker uses multiple high-efficiency long-throw custom bass drive units.

Each treble unit is a very high quality 25mm (1") Meridian piston in a short horn, using an aluminium dome with a silver voice-coil. It is extremely well matched to the woofers, and also tonally very compatible with the other drivers employed in the Meridian range.

Power amplifiers

The speakers are driven by multiple independent highpower, low-feedback power amplifiers. 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 substantial toroidal transformers feeding high-quality, audiophile-grade capacitors.

Cabinet

Each DSP loudspeaker is carefully designed with internal bracing and damping to give incredibly low levels of cabinet resonance, resulting in low coloration and excellent mid-range transparency.

The DSP5200 and DSP5200HC are constructed using veneered plywood, braced and resin damped to produce an ultra-rigid cabinet.

The DSP5500, DSP5500C, and DSP5500HC are constructed using thick veneered MDF sides bolted through a 1.5mm steel plate onto the main cabinet, giving extremely low levels of cabinet resonance and excellent bass-mid isolation.

The DSP7200 cabinet is fabricated from curved pressure-laminated panels, using multiple layers of selected woods and metal to achieve high stiffness and damping. Its narrow tapered shape gives optimum

Introduction

dispersion over a wide listening area. Each cabinet stands on three adjustable machined feet which can be fitted with spikes or skids.

Mounting options

In addition to the main vertical speakers, designed for use as the left/right speakers in a system, each model includes a single horizontal centre and/or a single vertical centre, designed for use as the centre speaker in a surround system.

The DSP5200HC and DSP5500HC are horizontal centre versions, designed for use either above or below a television.

The DSP5500C is a vertical version, designed for use as a centre speaker, and it uses fully shielded drive units so they it be placed next to a television without interference.

Meridian High Resolution (MHR)

All Meridian DSP 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.

remote, and ensure that they will work together as a fully integrated system.

The Meridian SpeakerLink connectors provide both Meridian Comms control and two-channel balanced digital audio in a single convenient RJ45 cable.

Meridian Comms also allows you to extend your hifi 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 DSP loudspeakers to illustrate the flexibility of Meridian components.

Available accessories

Each pair of main DSP loudspeakers is shipped complete with an MSR+ remote.

Other applications, and some advanced features, may require one or more of the following accessories, which can be purchased from your Meridian dealer:

Interconnecting leads.

•

AC11 SpeakerLink Hub, to allow interconnection

•

between newer products with SpeakerLink connectors, and products with Meridian BNC Comms or Meridian DIN Comms connectors.

Meridian Comms

Meridian DSP loudspeakers are part of the Meridian family of advanced digital, analogue, and video components. These incorporate a sophisticated communications link, called Meridian Comms, to allow you to control any combination of units using a single

DSP5200HC

Unpacking

Before you begin installation you should ensure that your DSP 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 DSP 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 repacking the DSP loudspeakers that you do not put undue pressure on the face containing the drive units, as they may be damaged if pressed.

Components

Each pair of DSP loudspeakers is supplied with the following components:

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 Cleaning, page 43.

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.

To fit the feet (DSP5200 only)

The feet ensure that the loudspeakers have a stable base, and can be adjusted to allow for uneven floors. Use the spikes for carpeted floors; they are designed to penetrate the pile without damaging or flattening the carpet. Retract the spikes for solid floors.

If any of these items is missing please contact your dealer. We suggest that you retain the packaging carefully for maximum protection in transit.

Caution

Meridian Audio has taken every care in the design, assembly, finishing and packing of this product. Some models include a high-gloss finish, which is achieved by painting up to five coats of polyester lacquer onto the plywood, each one hand polished.

Each DSP loudspeaker needs four feet, fitted as follows:

Insert the spike into the foot so that the nut engages

•

in the hexagonal recess in the bottom of the foot, and screw each spike into the threads on the bottom of the loudspeaker. Do not fully tighten the lock nuts at this stage.

On solid floors retract the spike so it does not extend

•

When all four feet have been fitted, carefully set the

•

DSP loudspeakers upright in their playing positions and remove the rest of the packaging.

On carpeted floors, adjust the spikes until the

speaker, using the self-adhesive pads.

Tightening the drive units

The DSP loudspeakers typically take about two weeks of normal use for the drive units to settle. It is therefore recommended that you tighten the mounting bolts on each drive unit every few days during this period. Tighten the bolts in symmetrically opposite pairs using the 3mm hex wrench supplied.

You should then check and if necessary re-tighten the drive units every few years.

Removing the grilles

The grilles are deliberately designed to fit tightly to avoid vibration during operation, and they should be removed using the following procedure to avoid damaging the loudspeaker.

The grille consists of elastic material stretched tightly over a plastic ring. The plastic ring includes two indentations at the three o‘clock and nine o‘clock positions, which you can locate by gently depressing the grille fabric.

ring forwards until it comes free of the speaker. The grille fabric is very resilient and any depressions will soon disappear.

Note: On no account attempt to remove the grille with a hard object, or attempt to lever it out from the outside edge, as you will damage the edge of the speaker surround and the grille itself.

Hold the ring by one of the indentations by depressing the grille fabric with your thumb, and then wiggle the

Positioning the digital 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 DSP loudspeaker at least 0.5m (20") from a corner, and position them approximately 0.25m (10") from the wall.

If you are using a DSP 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.

You can configure the frequency response of the DSP loudspeakers to compensate for a position close to a wall or corner; see page 38.

To adjust the frequency response

Connecting up the DSP loudspeakers

Using the DSP loudspeakers

In systems with a Meridian preamplifier or control unit all of the functions of the DSP loudspeakers, including volume, treble, and bass, are operated via the controller. For more information refer to the user guide for the preamplifier or control unit, and you can ignore this chapter.

The DSP loudspeakers can also be connected directly to up to two digital sources to create a complete, minimum system. This chapter provides step-by-step instructions for operating the DSP loudspeakers in a system with no Meridian preamplifier or control unit.

Selecting a source

When not playing, the DSP 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 DSP 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 DSP 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 RJ45 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 34. To configure an individual source to use a different input see

Using the DSP

loudspeakers

Adjusting the volume

The DSP 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 DSP 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 (silence) the sound

Press Mute on the remote.

•

To restore the sound

Press Mute again on the remote.

•

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.

Using the DSP

loudspeakers

Changing the listening position

The balance control of the DSP loudspeakers uses digital signal processing to compensate for an offcentre 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 DSP 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.

Configuring the DSP loudspeaker does not have any effect

Make sure that you are configuring the DSP loudspeaker used as the master digital loudspeaker in the system. This determines the configuration of all digital loudspeakers in the system.

There is radio interference

The DSP 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 DSP loudspeaker and its cabling. Ensure that the receiver uses well-screened antenna

•

cable. Relocate the receiver with respect to the DSP

•

loudspeaker. Connect the receiver and this product to different AC

Unit goes silent when played hard and displays ‘Hot‘

The DSP 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

Drive units move when the speaker is switched on or off

This is normal as the speaker active electronics settle.

Check the cables are connected correctly.

•

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.

Cleaning

Cleaning (DSP5200, DSP5200HC, and DSP7200 only)

On black speakers, 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.

Troubleshooting
