Introduction Welcome to the Meridian DSP loudspeaker range! This User Guide provides full information about using the 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.
INTRODUCTION Power amplifiers The speakers are driven by multiple independent high-power, lowfeedback 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.
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.

Setting up the DSP loudspeakers This chapter explains how to install your DSP loudspeakers. It describes what you should find when you unpack the speakers, how you should connect them to your other audio equipment, and the siting constraints.
SETTING UP THE DSP LOUDSPEAKERS 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.
SETTING UP THE DSP LOUDSPEAKERS Caution (DSP6000 and DSP6000C only) 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.
SETTING UP THE DSP LOUDSPEAKERS • When all four feet have been fitted, carefully set the DSP loudspeakers upright in their playing positions and remove the rest of the packaging. To fit the rubber bumpons (DSP5000C and DSP5500HC only) • Attach four bumpons to the underside of each speaker, using the selfadhesive pads. To install the head units (DSP6000 or DSP6000C only) • Locate the three pillars and screw them into the three holes in the top of each base unit.
SETTING UP THE DSP LOUDSPEAKERS Radio interference FCC Warning: This equipment generates and can radiate radio frequency energy and if not installed and used correctly in accordance with our instructions may cause interference to radio communications or radio and television reception. It has been type-tested and complies with the limits set out in Subpart J, Part 15 of FCC rules for a Class B computing device.
SETTING UP THE DSP LOUDSPEAKERS Positioning the digital loudspeakers Safety warnings • Do not expose the speakers to dripping or splashing. • Do not place any object filled with liquid, such as a vase, on the speakers. • Do not place naked flame sources, such as lighted candles, on the speakers.

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. However, the DSP loudspeakers can also be connected directly to up to two digital sources to create a complete, minimum system.
USING THE DSP LOUDSPEAKERS 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.
USING THE DSP LOUDSPEAKERS Changing the display The DSP loudspeakers display information about the current settings on the 8-character front-panel display. In addition, three coloured indicators show status information. To change the displayed information • Press Display.
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 red A or V keys on the remote.
USING THE DSP 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. If you have a Meridian Surround Controller these functions are performed via the sound controller.
USING THE DSP LOUDSPEAKERS Changing the listening position The balance control of the DSP loudspeakers uses digital signal processing to compensate for an off-centre listening position by delaying and diminishing the sound in one speaker, thus If you have a effectively shifting the speaker’s image back. Meridian Surround Controller these functions are performed via the sound controller.
Configuring the DSP loudspeakers This chapter explains how to configure the DSP loudspeakers to suit the other equipment in your system. The first stage in configuring the DSP 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 DSP LOUDSPEAKERS Choosing standard settings The DSP loudspeakers provide the following five alternative standard settings, called Types, which configure all aspects of the DSP loudspeakers into the most commonly needed configurations: Type Description 1 For use with a Meridian control unit such as the 562V.2. 5 For use with a CD player connected to D1; all other sources use D2. 6 For use with a Meridian Surround Controller. 7 For use in a second room.
CONFIGURING THE DSP LOUDSPEAKERS To specify the speaker position • Press A or V to specify the speaker position. The options are shown in the following table: Display Position L. Left. R. Right. C. Centre (Type 6 only). S.L. Left surround (Type 6 only). S.R. Right surround (Type 6 only). To choose master or slave You should select one loudspeaker to be the master; this will normally be the centre channel. For more information see Setting up the DSP loudspeakers, page 13.
CONFIGURING THE DSP LOUDSPEAKERS 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 Choosing standard settings, page 30.
CONFIGURING THE DSP LOUDSPEAKERS Configuring the sources When the master DSP 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 34. If the configuration you want is not catered for by one of the standard settings, you can configure each source individually.
CONFIGURING THE DSP LOUDSPEAKERS The options are summarised in the table below: Option Label Audio input Comms type Address FIFO Initial value Radio D1 2C 1A FF. Y 34 Alternatives Explanation CD, Radio, LP, etc. The label used to identify the source on the front panel display. D1 or D2. Choose D1 or D2 to specify the input. 1C – 9C, or NC. Choose 1C for a Meridian CD player, 2C for a Meridian FM Tuner, 3C for a Meridian DVD player, or NC otherwise. 1A – 8A.
CONFIGURING THE DSP LOUDSPEAKERS Configuring the setup options When configuring the DSP loudspeakers, point the remote at the speakers, even if you have a Meridian Surround Controller. The setup options allow you to adjust the frequency response of the loudspeakers to compensate for their position. You only need to configure the master loudspeaker. To select Setup mode • Turn off the DSP loudspeaker using the power switch on the back panel.
CONFIGURING THE DSP LOUDSPEAKERS To adjust the centre frequency response and tilt offset If your system includes a DSP centre speaker you should set Centre Y on the master speaker. An additional frequency response option is then provided to allow you to adjust the centre speaker, with the options: C.Fre, C.bou, C.Sb1, C.Sb2, and C.Cor. • Press Function > or Function < until the display shows the current centre frequency response. C.
Troubleshooting This chapter provides suggested solutions to typical problems that may occur when setting up the DSP loudspeakers. If you are still not able to resolve a difficulty with the help of this guide and the suggestions in the following pages, please contact your Meridian dealer or Meridian Audio Ltd.
TROUBLESHOOTING Troubleshooting Display on front panel not lit Check the following: • There is AC power connected to the socket on the back of the DSP loudspeaker. • 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 DSP loudspeaker. If these are all intact, contact your dealer. Remote not working Check the following: • The battery in the Meridian System Remote.
TROUBLESHOOTING Drive units move when the speaker is switched on or off This is normal as the speaker active electronics settle. 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. Unit stays in standby • Check that it is connected correctly. • Turn the system on from another Meridian product in the system.
TROUBLESHOOTING Cleaning Cleaning (DSP6000 and DSP6000C only) 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.
TROUBLESHOOTING Service and guarantee Service The Meridian components have been carefully designed to give years of untroubled service. There are no user-serviceable parts inside the case, nor do the units require any form of maintenance. In the unlikely event that your DSP loudspeaker fails to function correctly, it should be returned, in its original packaging, to your Meridian dealer. In case of difficulty within the UK or USA please contact the appropriate sales and service address shown on page ii.
