Introduction
Introduction 5
Congratulations on choosing DSP5000 digital loudspeakers. We are confident that they will give a quality to your music that is unprecedented, and bring years of listening pleasure. This manual will enable you to get the most from them.
The DSP5000 is a sophisticated product. You should therefore read all the supplied documentation before fully installing the DSP5000, particularly if you intend to customise its functions.
We have supplied a Getting going sheet for those of you who want to hear the DSP5000s immediately, and then perhaps spend a little longer deciding on how best to set them up in your home.
DSP5000s can be adjusted in many ways, all of which are explained in this manual. If you have any queries regarding the DSP5000, remember that your Meridian dealer has been selected for his expertise. You should refer to him in the first instance.
We have made this unique product as simple to use as possible so that it will bring you a new dimension of listening pleasure.

Master and slave speakers
In every room containing DSP5000s, one speaker is chosen (by means of either factory setting or user setup) to be in charge of the other Meridian components in that room. We refer to this as the master speaker. It controls the functions of the other DSP5000, and communicates with all the other Meridian products in the system via the M5-lead provided. The master speaker is also the one that ‘watches’ the remote control, and should therefore be placed so that it has the best possible view of the room, although the connections between the other components of your system must also be considered.
An installation may use 1, 2, 3 or 5 master speaker and the others used as slaves.
The master is identified by a red light in the display window.
1
DSP5000s: one will always be the
Centre, left, right and surround
Since the digital audio signal is in stereo format, the DSP5000 needs to be told if it is a centre, or on the left or right. We refer to the DSP5000 which is on the left when viewed from the listening position as the left speaker.
If you have more than one Meridian Digital Speaker, the master can be any of the positions. The choices master/slave and position can be made independently – since selecting which is to be master affects the way the cables run in your installation. As supplied, the DSP5000 is set up as a left master, but you can alter this if necessary using a Type setting (see page 33) or in Config (see page 34).
DSP5000s can be used as surround speakers. In this case they are set to be surround left or right.

DSP5000 User Guide
Description 7
Control
The DSP5000s are operated either by commands received from the Meridian System Remote (MSR) supplied with the loudspeakers, or by commands received through the communications cables of a Meridian installation (for example, from the front panel of a 562 or 601).
The remote control provides enough keys to allow you to drive a Meridian installation via the DSP5000s, and this is the method to be preferred.
Note If you have any 200-Series components to connect to the DSP5000, then the DSP5000s and any 500-Series components must be operated in 200 mode. See page 30.
Note In a 200-Series system DSP5000 must be set to Type 2 (see page
32) and the MSR must be configured to Option 3 (see MSR User Guide). An MSR not set to Option 3 will give very confusing results in a 200­Series system. In all cases where DSP5000 is used in a system containing 200-Series components the Meridian 209 system handset should not be used.
General background
The DSP5000 contains unique combinations of technology, and you should bear the following in mind.
1. Each DSP5000 is controlled by an internal computer. This interprets the commands from the remote control, communicates with other Meridian components, operates the display and supervises the digital audio process.
2. The DSP5000, in common with other components of the Meridian Multiroom system, uses a technique called ‘source mapping’.
Source mapping allows flexibility in the following attributes of the source:
its identity
the associated display
which key on the MSR calls the source up
which physical input of the DSP5000 receives the signal from this
source
whether the source is controllable
3. As a convenience feature, the tone-control settings of DSP5000 can
be restored to your chosen favourite settings for each source. This means that if you want to keep a combination of tone settings you
must set these up in the Setup mode. See page 31 for an overview.
Unpacking the DSP5000
In the two packs you should find:
2 DSP5000 digital active speaker base units complete with grilles
8 screw-in spikes with lock nuts and foot caps
wrench for spikes
MSR handset and user guide
battery for handset
DSP5000 user manual (this manual)
Getting going sheet
2 power cords suitable for your territory
composite system cable M5 (phono + DIN to phono + DIN, 8 metres)
composite system cable S5 (phono + DIN to phono + DIN, 6 metres)
DSP5000 User Guide
Installation 8
hex wrench (3mm), for drive units
If any of these items is missing, please contact your dealer. We suggest that you retain the packing carefully, as it provides maximum protection for the unit in transit.
NOTE Take great care when unpacking or re-packing the DSP5000 that you do not put undue pressure on the front, as the drive units may be damaged if pressed.
Fitting the feet
It is easiest to fit the feet with the speakers upside down, before removing the inner carton or foam packing. Each DSP5000 needs four feet, fitted as follows:
1. Find the eight screw-in spikes, and the lock nuts, foot caps and wrench
provided.
2. Fit a lock nut to each spike, about 2mm away from the end of its
thread. If a foot is required rather than a spike, fit a foot cap. Screw each foot into the threads on the bottom of the base units. Do not fully tighten the foot at this stage.
3. When all four feet have been fitted, carefully set the DSP5000s upright
in their playing positions.
4. Remove the rest of the packaging.
Meridian System Remote (MSR)
The MSR uses infra-red transmission to operate the DSP5000. It uses a PP3 battery (supplied but not installed).
When a key is pressed, an indicating light shows in the window of the MSR. This light becomes inconsistent or weak when the battery needs changing. Normally the battery will last for up to a year, but we recommend that you change the battery routinely every six months, since there are no front-panel controls on the DSP5000 and the system therefore cannot be used without a working handset.
The MSR is supplied with its own user guide. This explains many details of operation and also how to fit and change batteries.
The MSR is suitable for DSP5000 fitted with control EPROM version 2.2 or later. (See page 16). If you want to use MSR with an earlier version of DSP5000 (EPROM version 1.x) or with any 200-Series components in the system, then the MSR needs to be configured to Option 3 – see the MSR User Guide and the DSP5000s have to be set to type 2 – see page 32.
To check the MSR, press any key and look for the flashing yellow light. Note Good-quality alkaline batteries last longer than other sorts of
battery, and we advise you to use one in your MSR.
Note Do not store the unit where it may get too hot.
Note Do not store the unit face down, or rest objects (e.g. magazines) on
top of it. Doing so could cause one of the keys to be left pressed down, which would considerably shorten the life of the battery.
Note Do not allow the MSR to become wet. If drinks are accidentally spilt on it, remove the battery and let the MSR dry out. If necessary consult your dealer.

General precautions
Before carrying out any installation, you should ensure that the DSP5000 is marked with the correct voltage for your local AC supply. Should this not be the case, do not proceed, but contact your dealer.
As a general rule, you should not make any connections to the DSP5000, or to any other component in your system, when the AC power supply is switched on.
Customising features
For full details of Type settings and configuring DSP5000, see
Customising DSP5000: an overview, on
29
The DSP5000 is very flexible. Its functions can be significantly customised, which means that you can set up your system so that it suits you exactly.
Customising DSP5000: an overview, on page 29, describes your options in detail. By the time you have set up DSP5000 according to your needs, you will be aware of how the alternative choices available to you can differ from the standard configurations.
We recommend that you first get to know the DSP5000 by using one of the standard setups, and by working through this manual. Do not be afraid later to experiment with customising – we have given you a simple way of getting back to where you started from! (see page 32).
DSP5000 as provided has 3 standard configurations which we call Type settings. Each Type gives a different set of standard options; this feature is described fully on page 32.
Using DSP5000 10
Warning By selecting a Type, you automatically reset all custom settings for DSP5000 to the factory defaults – this includes all tone settings.
DSP5000 has 7 operating modes (not to be confused with setup Types):
Standby
Normal
Type
Config
Setup
Calibrate
Test
Standby and Normal are the everyday operating modes. The basic operating instructions refer to these.
Type is used to reset the DSP5000 to one of five factory-preset conditions. The main uses of Type are to specify what type of preamplifier is being used, and to make an initial choice of left/right and master/slave speakers.
Config could be considered as an editing setup mode. In Config you can choose any aspect of left/right, master/slave, sources or preamplifiers individually, without losing any other settings you may have made.
Setup is an operating mode in which the speaker plays and in which additional menu items are available. The idea behind Setup is that in this mode you can choose and store in memory the preferred tone settings for every source. Going to Normal operation then prevents them from being accidentally lost, and can simplify everyday operation.
Customisation is described more fully in Configuring DSP5000: an overview, on page 29.

Calibration and Test are intended only for use by the factory or by service engineers.
Connections
You will need to make four types of connection to the DSP5000:
digital audio
communications
master–slave
AC power
Digital audio connections will need to be made to other components in your system. Communications connections have to be made to most of the other Meridian components in your system in order for them to act as one system. The connections to your DSP5000 are very important, and care should be taken in deciding which connections to make.
Connection details for a wide variety of systems are described in the sections following page 42.
Siting
We recommend that you now set up the system so that you can listen to music and adjust the position of the DSP5000s if necessary. This can be accomplished by following the instructions in the Getting going sheet, or those in the rest of this manual.
The locations chosen for a pair of DSP5000s are crucial to getting the best possible acoustic result. For stereo, the two speakers should ideally be equidistant from the main listening position, and the same distance apart.
The DSP5000 has bass controls to allow adjustment of the low-frequency response to room acoustics and positioning. You should nevertheless try to achieve the following:
If possible, have the most acoustically absorbent wall in the room
behind the speakers. They could, for example, be in front of an open bookcase or curtained window, or on each side of a bow window.
If possible, have each DSP5000 at least 50cm from a corner.
If possible, have each DSP5000 at least 20cm from the back wall.
After finding by trial and error the best positions for the DSP5000s, use
the spiked feet under the protective black plastic foot caps where possible. This will give improved definition to the sound, and better physical stability.
If possible, locate the listening position so that your head is at least
60cm from the wall behind you (unless this is acoustically absorbent).
Consider the following practical points:
If possible, you should locate the DSP5000s so that the electronics
(back) of the speaker are not subjected to long-term strong sunshine. In Standby the back plates should be cool (less than hand-hot).
If possible, you should locate the DSP5000s so that the one chosen to
be the master speaker does not receive direct sunlight on the front display window. If it does, the DSP5000 may not ‘see’ your commands from the MSR. No harm will be done to the DSP5000; it will simply be inconvenient.
The location of the master speaker also depends on the connections
to it from the rest of your system. See page 42.
You should not, if possible, locate the DSP5000s with their backs to
any heat source – for example, a central heating radiator.
You should try to arrange a separate AC power outlet for each
DSP5000. The use of adapter units is discouraged, since at best they degrade the possible sound quality.
DSP5000 User Guide
Using DSP5000 12
Final adjustments
When you are sure that the DSP5000s are in the right places, you should adjust and finally tighten the feet with the wrench provided.
We strongly suggest that you try to use the spike feet, in order to get the best sound.
Foot caps may be fitted if the spikes are unacceptable
The spikes allow the DSP5000s to rest firmly on the floor. A spike passes through carpet to the wood or concrete below, and does less damage in the long run than a wide foot.
The best sound possible will only be obtained if the DSP5000s are firmly mounted and cannot rock at all. If the finish of the floor prevents the use of spikes, leave the plastic covers on, but adjust the feet to the floor so that the DSP5000s are vertical and show no tendency to rock.
One or two days after installation, check the tightness of the screws retaining the drivers. These screws may loosen during shipping or with extremes of temperature or humidity, and the speaker will not sound its best if they are loose. The screws should be checked every few months, particularly if the speakers are used to play loud music for long periods.
Tip Like all digital products, the DSP5000 emits some radio-frequency signals. For this reason, try to keep all power cables and communications leads away from audio, TV and FM antennae, and from loudspeaker cables. If you spend some time laying out the cables carefully, you will be rewarded with the best possible performance later.
Starting off with DSP5000
First install the DSP5000s, using the information in the Getting going sheet. When they have been used for a while, you may wish to change the setup in order to fine-tune it to your requirements. To achieve this, refer to the setup section of this manual, beginning on page 30.
Checking
Before turning on the power, check once again that you have made all the connections correctly and that you have not disturbed any existing connections in the process.
Switching on
The power switch is located directly next to the power inlet on the right­rear of DSP5000.
1. Switch on the power to the sources, but for now do not start them
playing.
2. Turn on the power switch at the rear of the master DSP5000. A small
point on the display should now be illuminated:
••
3. Turn on the power switch at the rear of the slave DSP5000. A small
point on the display should now be illuminated:
If there are no lights
Check the integrity of your power connections, including any fuses in your supply. If the Standby point is still not illuminated and the rest of your system is functioning, contact your dealer for help.
DSP5000 User Guide
Using DSP5000 13
Starting the DSP5000
To start the system, press any of the input keys on the MSR (CD, LP, Radio, Video, Tape 1, and Tape 2). For example:
1. Press CD
In Type 1 this will select the physical input D1, and both DSP5000s will display
cd 65
65 is the volume number, and cd means that the DSP5000 expects the
source to be a Meridian CD player which can be controlled by the MSR. Cd would be the correct display if your CD player were not a Meridian product, in which case you could still listen to it, but the MSR would not control it.
Note The response of the DSP5000 to commands will be slower if it is set up to expect a Meridian component when one is not connected. If non­Meridian components are used, the DSP5000 should be set up accordingly.
The Meridian components will now have come out of Standby.
1. Start up your CD player in the normal way. If all is well you will soon
hear the music. If you do not, check all connections, and if necessary refer to the DSP5000 setup manual.
To put the system into Standby:
1. Press Off
If the connections are correct, both DSP5000s and any other Meridian components should revert to Standby mode.
Note If they do not, there may have been a mistake in the setup of the DSP5000s, or in the connection of the communications network.
Standby
The entire Meridian system is designed to be left connected to AC power at all times.
The Standby state ensures that the components operate at maximum
efficiency from the moment when you start listening. It is perfectly safe and consumes a negligible amount of power. However, when you are not going to use your system for some time (when you are going on holiday, for instance), we would advise you to disconnect it from the AC power supply.
The memory functions of DSP5000 use EEPROM, which is non-
volatile, and therefore has the ability to store your data indefinitely when the power is switched off.
DSP5000 User Guide
Basic operation of DSP5000
Note DSP5000 is factory set for the most common installation, one using
the full features of a Meridian 500-Series CD player and 562 controller. We call this a Type 1 installation. For more details, see Appendix 1 on page 55.
Selecting sources
To switch from CD to another input, say Radio:
1. Press Radio
In Type 1, this will select RD on a Meridian 562. Both DSP5000s display
rd 65
Here rd means that the source is a radio tuner, and that the DSP5000 expects a Meridian 504 to be connected to the Radio input of the 562 and into the communications system. The 504 can now be controlled by the MSR, and its status can be displayed on the master DSP5000. 65 is the volume number.
The other input keys on the MSR (e.g. LP, Tape 1, Video and Tape 2) operate in a similar way in Type 1:
The LP input of a Meridian 562 is engaged. The D1 input of the DSP5000 is selected. The display shows
LP 65
Using DSP5000 14
The Tape 1 input of a Meridian 562 is engaged. The D1 input of the DSP5000 is selected. The display shows
t1 65
Note These responses are for DSP5000s set up for Type 1, and can be
changed. See later. Selecting a source will bring DSP5000 out of Standby. Note If you have stored a preferred tone setting for a source, you must
recall it after switching to the source; recall settings by pressing Store.
Putting the DSP5000 in Standby
1. Press Off on the remote control
Coming out of Standby
To start up the DSP5000 from Standby:

digital ‘overload’ – flashing yellow light in the window
blank display, in which the speaker only illuminates the display when
you use the remote control

track and time information, when the source is a digital one that
includes these codes, e.g. a CD
error messages
CD track selection, if a Meridian CD is connected
frequency, preset number and preset selection when the installation
includes a Meridian tuner
Note Using the Display key, you can change the master speaker's display. For example, the slave speaker can display source and volume while the master displays track, time or frequency.
Note Only the master can display tuner, track and time information, as this comes from the products to the master speaker via the M5-lead, and is not passed on to the slave.
Changing the display
The DSP5000 has several display modes. To change the display:
1. Press Display
The master DSP5000 will cycle through the five display options, which are:
source + volume number (convenient legends which you have
chosen are displayed)
blank
track number for CD; preset number for radio
track time for CD; frequency for radio
disc time for CD
The blank display is for those users who are distracted by lights. If you have chosen this option, the lights and display will only come on when you are operating the DSP5000.
The source + volume display looks like the following example:
t3
This indicates that you are using the Tape 3 source with a volume of 56.

CD displays
1. With the CD playing, press Display
The display on the master will change to give something like this:
DSP5000 User Guide
Using DSP5000 16
1
Here 1 is the number of the track currently playing on the disc. If the disc includes significant index points, the display will be like this:
3.4
3.4 here means track 3, index point 4. In theory, with the right disc, we
could see displays of track and index up to 99.99. Index point 1 is never displayed.
While the CD player is loading a disc (reading the disc’s directory), the DSP5000 will show the directory message:
dir
At the end of a CD, the DSP5000 will detect the lead-out track and momentarily display the message
End
1. With the disc playing, press Display again. You will see a disc time
display, counting up as the disc plays.
2. Press Display again. You now have a display of time for the current
track only, also counting up as the disc plays.
3. Press Display again. The display should go blank on both master and
slave.
4. Pressing Display again brings you back to the source and volume
display.
One useful way to set up DSP5000s is to leave the track display on the master, since the slave always displays the source and volume.
If the CD player is in the same room, you can adjust its display to give you additional time information.
Try pressing Display until you are familiar with its operation.
Other information reviewed in Standby
1. Press and hold Display
The display will show the version number of the microcontroller software, followed by the currently-loaded DSP software. For example:
2.2 P1.81 d1.2 441b
Note The last DSP version number will depend on the operating mode of
the DSP5000. The first two digits represent the sampling frequency; DSP5000 automatically reloads a new program for each sampling rate. The version numbers will also be different in Test and Calibrate.
Volume
To raise or lower the volume:
1. Press the upper or lower
The volume level displayed should count up or down, and will range from 1 to 99. Each step is precisely 1dB.
∧∧ or ∨∨ red key
DSP5000 User Guide

1. Press Mute
The Mute key toggles between mute and demute. The system may also be demuted by selecting another source, or
adjusting the volume.
The menu system
The DSP5000 offers a number of user choices which are normally accessed less frequently than, for example, source and volume. To make it easier to operate these less commonly used functions, we have provided a flexible menu system to guide you through the options. One important advantage this gives is complete flexibility for future system control options. Please note:
The menus are different in Normal and Setup modes
To access the menus
1. Use the menu keys on the remote control w n s e
To move between menus
1. Press either the w or the e menu key on the remote control
In Normal mode, the menu choices are:
Tilt
Bass
Phase
Balance
Axis
Tip This is also the way to review settings you have made. The DSP5000 will cycle through its menus, displaying the current choice in each one as it goes.
In Setup mode, an additional menu item appears for boundary or free bass alignment or choice of subwoofer modes.
To change the choice in a menu

Balance
The balance control in the speaker is only used if you have two DSP5000s connected as a conventional stereo pair.
If you have set up the DSP5000 as a centre-channel then the balance control is ignored. If the speaker is used with a Meridian 565 Digital Surround Processor, then the balance function is taken over by the 565. See the manual supplied with 565.
Use of balance controls
The use of the balance control has been misunderstood for some time. It has been assumed that you can use it to move the image to one side,

perhaps to compensate for a non-central listening position or a highly asymmetric layout.
This is certainly not the case. Stereo sound is dependent upon time differences between the signals from the channels. To get the best out of a normal stereo system, you should be in the correct position in relation to the speakers.
The balance control of the DSP5000, however, uses digital signal­processing to delay and diminish the sound in one speaker, thus effectively shifting the speaker’s image back. Thus balance control compensates, to a certain extent, for an off-centre listening position. If you sit off-axis, this control will rotate the image.
Note Because the use of the balance control processes the digital signal, you may hear a slight clicking as the balance is adjusted.
How to use the balance control in a pair of DSP5000
If you are playing a CD, press Display enough times to get the permanent display:

Here ## represents the volume number. (This will help you to understand the functioning of the balance control better, but it is not essential).

master display will momentarily show

This allows you to ask the DSP5000 what its balance setting is without changing it.
Note We call this kind of display a cursor – in this case, the tilt cursor. DSP5000 uses several cursors to access functions such as tilt, bass, phase, track selection and preset selection.
To get rid of a cursor, either
wait a few seconds, or
select another cursor, or
hit another (inactive) key
To change the balance setting:
1. Make sure that you can see the balance cursor display on the master:

2. Press the n menu key. The display will change to
