Introduction
Congratulations on choosing DSP5500 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 DSP5500 is a sophisticated product. You should therefore read all
the supplied documentation before fully installing the DSP5500,
particularly if you intend to customise its functions.
We have supplied a Getting going sheet for those of you who want to
hear the DSP5500s immediately, and then perhaps spend a little longer
deciding on how best to set them up in your home.
DSP5500s can be adjusted in many ways, all of which are explained in
this manual. If you have any queries regarding the DSP5500, 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.

DSP5500 description
You will find it simpler to understand how the DSP5500 works if you
consider it as a combination of the following components:
• digital preamplifier, to select and control up to two digital sources
directly, and to provide fixed and switched digital output for the other
DSP5500
• digital audio processor, whose functions include decoding as well as
error detection and correction
• digital signal-processor, dealing with tone controls, digital crossover,
balance and volume
• three precision digital to analogue ∆Σ converters for bass, mid and
tweeter
• remote control for all functions, including volume, balance, mute and
various tone controls
• controlling computer
• RS232 control and display capability
• Meridian 500-Series communicator
• 3-way active loudspeaker, with three drive units and three 75W power
amplifiers per speaker
Master and slave speakers
In every room containing DSP5500s, 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 DSP5500, 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 1 DSP5500s: one will always be the
master speaker and the others used as slaves.
The master is identified by a red light in the display window.
Centre, left, right and surround
Since the digital audio signal is in two-channel stereo format, the
DSP5500 needs to be told if it is a centre, or on the left or right. We refer
to the DSP5500 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 DSP5500 is set up as a
left master, but you can alter this if necessary using a Type setting (see
page 32) or in Config (see page 33).
DSP5500s can be used as surround speakers. In this case they are set to
be surround left or right.

DSP5500 User Guide
Description

Control
The DSP5500s 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).
The remote control provides enough keys to allow you to drive a Meridian
installation via the DSP5500s, and this is the method to be preferred.
Note If you have any 200-Series or 600-Series components to connect to
the DSP5500, then the DSP5500s and any 500-Series components must
be operated in 200 mode. See page 29.
Note In a 200-Series or 600-Series system DSP5500 must be set to Type
2 (see page 31) 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 200-Series system. In all cases where DSP5500 is used in a system
containing 200-Series components the Meridian 209 system handset
should not be used.
General background
The DSP5500 contains unique combinations of technology, and you
should bear the following in mind.
1. Each DSP5500 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 DSP5500, 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 DSP5500 receives the signal from this
source
• whether the source is controllable
3. As a convenience feature, the tone-control settings of DSP5500 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 30 for an overview.

Unpacking the DSP5500
Caution:
The DSP5500 is
a very heavy
loudspeaker.
Please exercise
care when
moving it.
In the two packs you should find:
• 2 DSP5500 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
• DSP5500 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)
• hex wrench (3mm), for drive units
• hex wrench (8mm), for side panels
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 DSP5500 that
you do not put undue pressure on the front, as the drive units may be
damaged if pressed.
NOTE Do not move the DSP5500 around until the feet are fitted. To do so
will almost certainly damage the lower corners of the side panels.
Fitting the feet
Fit the feet before
removing the
DSP5000 from
the packing.
Fit the feet before removing the DSP5000 from the packing.
It is easiest to fit the feet with the speakers on their sides, before
removing them from the carton or foam packing. Each DSP5500 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 DSP5500s 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 DSP5500. 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 DSP5500 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.
If you want to use MSR with any 200-Series or 600-Series components in
the system, then the MSR needs to be configured to Option 3 – see the
DSP5500 User Guide
Installation
9
MSR User Guide and the DSP5500s have to be set to type 2 – see page
31.
To check the MSR, press any key and look for the flashing red 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.
Note Additional MSRs can be obtained from your dealer if you would
prefer to have more than one.

Installing your DSP5500
General precautions
Before carrying out any installation, you should ensure that the DSP5500
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 DSP5500,
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
DSP5500, see
Customising
DSP5500: an
overview, on
page 28
The DSP5500 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 DSP5500: an overview, on page 28, describes your
options in detail. By the time you have set up DSP5500 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 DSP5500 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 31).
DSP5500 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 31.
Warning By selecting a Type, you automatically reset all custom settings
for DSP5500 to the factory defaults – this includes all tone settings.
DSP5500 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 DSP5500 to one of eight 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 DSP5500: an
overview, on page 28.
DSP5500 User Guide

Calibration and Test are intended only for use by the factory or by service
engineers.
Connections
For details of
making all connections, see
Connecting
DSP5500, on
page 41
You will need to make four types of connection to the DSP5500:
• 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 DSP5500 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 41.
Siting
We recommend that you now set up the system so that you can listen to
music and adjust the position of the DSP5500s 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 DSP5500s are crucial to getting the
best possible acoustic result. For two-speaker stereo, the speakers
should ideally be equidistant from the main listening position, and the
same distance apart.
The DSP5500 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 DSP5500 at least 50cm from a corner.
• If possible, have each DSP5500 at least 20cm from the back wall.
• After finding by trial and error the best positions for the DSP5500s, 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 DSP5500s so that the electronics
(back) of the speaker are not subjected to long-term strong sunshine.
The back of the speaker must have sufficient air flow to cool the power
amplifiers. Standby the back plates should be cool (less than handhot).
• If possible, you should locate the DSP5500s so that the one chosen to
be the master speaker does not receive direct sunlight on the front
display window. If it does, the DSP5500 may not ‘see’ your commands
from the MSR. No harm will be done to the DSP5500; 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 41.
• You should not, if possible, locate the DSP5500s with their backs to
any heat source – for example, a central heating radiator.
DSP5500 User Guide
Using DSP5500
12
• You should try to arrange a separate AC power outlet for each
DSP5500. The use of adapter units is discouraged, since at best they
degrade the possible sound quality.
Final adjustments
When you are sure that the DSP5500s 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
Please note:
DSP5500 is very
heavy and the
spikes are
therefore
dangerous when
not resting on the
ground!
The spikes allow the DSP5500s to rest firmly on the floor. A spike passes
through carpet to the wood or concrete below.
The best sound possible will only be obtained if the DSP5500s 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 DSP5500s 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.
To access the drive unit screws, the grille has to be removed.
To remove the grille, first loosen the side panels with the wrench
provided.
Tip Like all digital products, the DSP5500 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 DSP5500
First install the DSP5500s, 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 29.
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 rear of
DSP5500.
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 DSP5500. A small
point on the display should now be illuminated:
DSP5500 User Guide

•
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.
Starting the DSP5500
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 DSP5500s will
display
cd
65
65 is the volume number, and cd means that the DSP5500 expects the
source to be a Meridian CD player which can be controlled by the MSR.
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 DSP5500 setup manual.
To put the system into Standby:
1. Press Off
If the connections are correct, both DSP5500s 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
DSP5500s, 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 DSP5500 use EEPROM, which is nonvolatile, and therefore has the ability to store your data indefinitely
when the power is switched off.

Basic operation of DSP5500
Note DSP5500 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 54.
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 DSP5500s display
rd
65
Here rd means that the source is a radio tuner, and that the DSP5500
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 DSP5500. 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 DSP5500
is selected. The display shows
LP
65
The Tape 1 input of a Meridian 562 is engaged. The D1 input of the
DSP5500 is selected. The display shows
t1
65
Note These responses are for DSP5500s set up for Type 1, and can be
changed. See later.
Selecting a source will bring DSP5500 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 DSP5500 in Standby
1. Press Off on the remote control
Coming out of Standby
To start up the DSP5500 from Standby:
1. Select a source, using the remote control
or
1. If the DSP5500 is part of a Meridian system, bring any component out
of Standby (for example, start up a Meridian CD player).

Display
DSP5500 displays information to help you operate it. Display information
can include:
• master indication – red light in the window
• digital ‘overload’ – flashing yellow light in the window
• blank display, in which the speaker only illuminates the display when
you use the remote control
• Standby indication
•
• setup information during programming
• selected source type
• selected physical input connection
• volume number
• tone control information
• absolute phase
• muted condition
• 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 DSP5500 has several display modes. To change the display:
1. Press Display
The master DSP5500 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 DSP5500.
The source + volume display looks like the following example:
t3
56
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:

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
DSP5500 will show the directory message:
dir
At the end of a CD, the DSP5500 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 DSP5500s 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.
Time displays will not be seen if the CD source is a Meridian 500 whose
time-code output has been switched off. For more details, see the 500
User Guide.

1. Press and hold Display
The display will show the version number of the microcontroller
software.

Volume
To raise or lower the volume:
1. Press the upper or lower ∧ or ∨ red key
The volume level displayed should count up or down, and will range from
1 to 99. Each step is precisely 1dB.
Note Subjectively one judges a volume increase of 9dB to be equivalent
to a doubling of loudness, so each volume number represents about a
11% change in loudness, with nine steps to double loudness.

Mute
To mute the sound:
1. Press Mute

To demute (restore the sound level):
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 DSP5500 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 DSP5500
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, corner or
free bass alignment.
To change the choice in a menu
1. Press either the n or the s menu key on the remote control
Balance
The balance control in the speaker is only used if you have two
DSP5500s connected as a conventional stereo pair.
If you have set up the DSP5500 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,
DSP5500 User Guide
Using DSP5500
18
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 DSP5500, 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 DSP5500
If you are playing a CD, press Display enough times to get the
permanent display:
cd
##
Here ## represents the volume number. (This will help you to understand
the functioning of the balance control better, but it is not essential).
1. Press the w or the e menu key until the balance display shows. The
master display will momentarily show
L.
0
This allows you to ask the DSP5500 what its balance setting is without
changing it.
Note We call this kind of display a cursor – in this case, the balance
cursor. DSP5500 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:
L.

showing that you have moved the balance one volume number towards
the left. After a few moments the display will revert, but you will now see
that the left speaker has a volume number one greater than the right.
3. Press n again. The display will move to

Tilt control
Tilt controls are combination controls that slope the frequency response of
the system slowly over the frequency range to make the sound brighter or
dimmer. They are less crude than conventional tone controls. The
responses of the tilt control in DSP5500 are shown in Appendix 4 on page
60.
To review the tilt setting:
1. Press the w or the e menu key until the tilt display shows. The
master display will momentarily show

The tilt can be adjusted between ±10 dBs, incremented in 0.5 dB steps.
To restore the flat condition, press Clear.
Note This also restores balance and bass.
To store a tilt setting, you must be in Setup mode; see page 38.
To recall a tilt setting, use the Store key; see page 22.
Tilt explained
The tilt control allows you to adjust the broad balance of the DSP5500 to
correct for the acoustics of your listening room, or for a poorly balanced
recording.
Normally, settings between 1.0 and –2.0 will give the most natural result.
All DSP5500s in the installation take on the same tilt setting as the
master. This is essential for correct stereo.
Bass control
The bass control allows you to adjust the bass response in the room. The
responses of the bass control in DSP5500 are shown in Appendix 4 on
page 60.
To adjust the bass:
1. Press the w or e menu key until the bass cursor display shows. The

the
1
All DSP5500s in the installation take on the same axis setting as the
master. This is essential for correct stereo.
Axis explained
The axis control allows you to adjust the optimum listening height of the
DSP5500 speakers. This means that you should be able to use the axis
function to bring the image more clearly into focus for different listening
heights. It changes the focus of the stereo image, not its perceived
position. You could think of it as a balance control operating in the vertical
plane.
The axis can be adjusted between 3 and –2, covering a range of listening
positions from standing eight feet from the speakers to sitting on the floor
at the same distance. Nominally 0 corresponds to on-tweeter-axis
listening; usually a listener will be below that position, so we recommend
that you start with –1 or –2.
Storing settings
In Setup mode you can store settings for:
• tilt – overall frequency balance
• bass
• boundary alignment (wall or free-standing)
• phase
• axis
An unusual feature of DSP5500 is that the tone control settings for tilt and
bass can be stored separately for each source. If, for example, you
happen to prefer a tilt setting only when listening to the video source, use
Setup to programme the DSP5500 for that setting. You can then recall the
setting by pressing Store while listening to the video source in Normal
mode.
At any time, you can use the Clear key to restore the following factory
settings :
• bass to 0.0
• tilt to 0.0
• balance to middle
You cannot store settings in Normal mode. See page 40.
Recalling settings
The settings stored in the DSP5500 can be recalled at any time. When
the display is normal (i.e. not a tone cursor):
1. Press Store
The DSP5500 will respond with
rEc.
Tip You can now compare the stored settings with the standard ones.
Use the Clear key to restore a flat response, then Store to recall the
stored settings.

Customising DSP5500: overview
28
Customising DSP5500: an overview
DSP5500 is a very sophisticated device, with a number of options which
allow you to set up exactly the system you need.
Programming of DSP5500s should take place after you have set up the
speakers and sorted out most of the connections. If you first get the
speakers working with some kind of digital input (e.g. a CD player), and
with some of the programming provided (e.g. Type 1), then you can
always go back to that starting point if you make a mistake.
Programming DSP5500 is a straightforward process, and you should not
be timid about experimenting. Although the setup is stored in non-volatile
memory called EEPROM, the EPROM (which you cannot change)
contains default Type settings, and you can return to these at any time.
Programming is the process of telling the DSP5500 what you want it to do
when the MSR is used. It is based round the Type system, which has five
different Types; you can choose the best Type for your own system.
Programming is carried out using the MSR, so you must first get the MSR
working, following the instructions on page 8.
The first step in programming DSP5500s is selection of the start Type.
Page 29 gives an overview of the five different Types, and these are
described further in Appendix 1, on page 54.
Note At any time during your programming of the DSP5500s, you can
turn off the power to the speaker you are working on, and all that you
have done will be remembered.
Note When you have finished programming, you can get out of the
programming mode simply by turning the power to the speaker off and
turning it back on again.
Restoring default settings
1. Switch off the DSP5500, using the power switch on the back, and wait
for 3 seconds
2. While pressing the 1 key on the remote control, switch the power on
again. The display will read
TY.
1
3. Release the 1 key
4. Switch off the DSP5500, using the power switch on the back
5. After a second, switch the DSP5500's power on again
Storing preferred tone settings
There is a special mode called Setup in which you can listen to the
loudspeakers normally, but in which the Memory feature is extended to
allow you to store tone settings as well as recall them. See page 22.
Note It is an unusual feature of DSP5500 that the speaker stores your
preferred tone settings for every source. You must therefore adjust these
settings one at a time and store each one.
DSP5500 User Guide
Customising DSP5500: how to
29
How to customise DSP5500
DSP5500 needs no customising to become operational. Once you have
your system established, you may wish to review the customising options
by reading Customising DSP5500: an overview (page 28).
Customising: general procedure
DSP5500 has seven operating modes (not to be confused with Types):
•
Standby
•
Normal
•
Type
•
Config
•
Setup
•
Calibrate
•
Test
Standby and Normal are the everyday operating modes. The basic
operating instructions refer to these.
When customising, you may need to use Type, Config and Setup, in that
order, before reverting to Normal. In other cases, you may only need to
use Config or Setup. Neither of these modes resets the DSP5500, so you
will not necessarily lose any settings you have previously made.
How to change back to Normal
To revert to Normal
1. Switch off the DSP5500, using the power switch on the back
2. After a second, switch the DSP5500's power on again
Note If you are in Calibrate or Test mode, refer to page 59 or 58.
Type: an overview
The Type
settings are
described in
detail in Appendix
1, on page 54
Type restores one of the default settings. Other than selecting
master/slave and left/right/centre/surround, no further actions are
possible. Type always resets all stored settings, with the exception of
calibration information. The DSP5500 does not play music in Type.
For example, Type 1 setup gives:
• 500 Series system only
• All sources select the D1 input
• DSP5500 expects a Meridian 500-Series CD and/or a controller such
as 562
For example, Type 2 setup gives:
• 200/600 Series system only
• CD selects the D1 input
• all other sources select the D2 input
• DSP5500 expects a Meridian CD preamp controller such as 208
Config: an overview
To use Config,
see page 32
Config could be considered as an editing setup mode. In Config you can
make individual choices about any aspect of left/right, master/slave,
sources and preamplifiers without losing any other settings you may have
made. In this mode, the DSP5500 is muted while you make the necessary
choices. The choices available in Config are outlined in the following
sections.
DSP5500 User Guide
Customising DSP5500: how to
30
Config: control settings
In Config, you can make selections that affect the way in which DSP5500
responds to certain keys. The main choices of this kind are:
• left or right
• master or slave
• Multiroom standby option
• sort of preamplifier or source switch box in the installation
Config: sources and inputs
In Config you can make decisions about sources, e.g.
• how many inputs (up to six) will be active
• which sources you can select
• which key on the remote control selects which source
• which logo on the DSP5500 display represents which input
• which physical input connection to DSP5500 will be used
Setup: an overview
To use Setup,
see page 38
Setup mode is quite different from Type or Config in that the speakers
function in this mode. In Setup, the master speaker menus are extended
to give you additional control, so that you can establish sonic preferences.
Setup mode lets you make choices based on extended listening.
The idea behind Setup is that you can choose, while listening,
• the boundary parameter (free or wall-mount)
• tilt settings for each source
• bass settings for each source
When you are happy with the settings you have chosen, they can be
stored in Setup. You then switch the system back to Normal.
The particular advantage of this system is that other users will not
inadvertently lose the settings you have chosen. When the system is in
Normal mode, the Store key will not store, performing only a recall
function. At any time you can
• reset factory default settings, using the Reset key
• adjust the settings, using the Menu keys
• recall your preferred tone settings with the Store key

Customising using Type
Type is a mode used specifically to restore the entire memory (except the
calibration memory) of DSP5500 to one of three factory-preset
configurations. For all three Types, Type resets the following:
• phase to positive
• axis to –1
• balance to central (L 0)
• tilt to 0.0
• bass to 0.0
• boundary to Free
• speaker to left master
Depending on the Type selected, the other options are set as follows.

When programming DSP5500 speakers, it is best to choose one of the
eight standard Types as a starting point, and it may be possible to find
one that meets your needs exactly. Otherwise, choose the one that is
closest to your requirements. Select it, and set up the master/slave and
left/right speakers, by means of the following steps:
Selecting Types
1. Switch off the DSP5500, using the power switch on the back, and wait
for 3 seconds
2. While pressing the 1 key (2 for Type 2, 5 for Type 5) on the remote
control, switch the power on again. The display will read
TY.
#
where # is the Type you have selected.
3. Release the # key
After a couple of seconds, the display will change to
L.
This indicates that this speaker will be a left master.

Choosing centre, left or right
If you have Typed the speaker with a 6, then the ‘Cen.y’ option is enabled.
This tells the speaker that there is a centre in the system and enables the
option to make the DSP5500 into a centre.
If you Typed the speaker with a number other than 6 then the ‘Cen.n’
option is selected and you do not get the ‘centre’ choice in this section.
To change the speaker from left to right, or vice versa.
1. Press the menu n or s on the remote control
The choices offered are L, r, C, LS, RS (for left and right surround).
Choosing master or slave
To change a master to a slave, or back again:
1. Press Play on the remote control

This display indicates a right slave.
Completing Type
When you are happy with your left/right and master/slave choices for this
speaker:
1. Switch off the DSP5500, using the power switch on the back
2. After a second, switch the DSP5500's power on again
Note Ensure that you have set the two speakers to opposite settings. One
must be left, the other right; similarly one must be the master and the
other a slave.
3. Make a note of your choices by marking both speakers on the back, in
the area provided on the label. Use a pencil so that you can change
the marking in future.
You now have your speakers set up in the start Type of your choice. The
following sections explain how to modify this setting to fine-tune the
system.
Note Under normal circumstances, you should not switch on the
DSP5500s while any key on the MSR is being pressed. If you do this, you
may accidentally select a new Type and change any previous
programming.
The Types are summarised in Appendix 1.
Customising using Config
For an overview
of Config, see
page 29
Config is a fine-tuning customising process carried out only on the master.
It will not cause any difficulty if you accidentally go to Config for a slave,
since the only options offered there will be left/right and master/slave.
In Config you can make choices about the way in which your system
responds to source-key selections. The important feature of Config
(differentiating it from Type) is that you can use it to change any setting of
the DSP5500 without erasing all the other setup choices you may have
made. Think of it as a configuration editor.
Config has three sorts of menu:
• root menu
• system menu
• source menus

The first letters tell you which options are available to you, as follows:
• 500 tells you that this system operates in Meridian 500-Series mode.
All controllable Meridian products must be 500 compatible. Also use
this if the DSP5500 is the only controllable preamplifier connected (i.e.
the source keys on the MSR will only select between the two inputs of
the DSP5500).
• Pr. means that the preamplifier for this system will be a Meridian 201,
601, 603 or compatible, and that source keys on the MSR will
automatically switch the inputs on the preamplifier regardless of other
selections. Implies and engages 200 mode.
• Cd. means that the preamplifier for this system will be a Meridian
CD/Pre (e.g. a 207 or 208). The first four input keys (CD, Radio, LP

Completing Config
When you are happy with your left/right and master/slave choices, and
with your other choices for this speaker:
1. Switch off the DSP5500, using the power switch on the back
2. After a second, switch the DSP5500's power on again
Note Ensure that you have set the two speakers to opposite settings. One
must be left, the other right; similarly, one must be the master and the
other a slave.
3. Make a note of your choices by marking both speakers on the back in
the area provided on the label. Use a pencil so that you can change
the marking in future.
Note When customisation is complete, switch the power off, wait for 3
seconds, then switch it on again to restore Normal operation and to save
what you have done.

the correct tone settings independently for every source you wish to
change:
1. Switch the power off and then on again to restore Normal operation
DSP5500 User Guide
Customising using Setup
39
In Normal operation, the settings you have made will be retained and
cannot be changed without going back to Setup.
Boundary controls
The frequency balance of a loudspeaker is changed, particularly in the
low-frequency regions, according to its proximity to walls or boundaries.
The DSP5500 is designed as a floor-standing system, so one boundary –
the floor – is nominally fixed. The DSP5500's response is also optimised
for a rear air-space of about 30cm behind the cabinet.
In certain circumstances, it will not be possible to pull the loudspeakers
out into the room, and they will have to stand with their backs to the wall,
in a corner, or in a recess.
DSP5500 has adequate DSP power to correct for the gross effects of wall
or flush-mounting. Of course, no signal-processing will remove the more
rapid echo from a nearer boundary, and such reflections will to some
extent disturb the depth of the stereo image.
In Setup, new menu entries appear, which allow a listening choice
between boundary-position settings and these can be made
independently for a left–right pair (or left + right + surrounds) and for a
centre.
Using the system boundary control for a left-right pair
This menu will appear on any master DSP5500 which is in Setup – even if
it is a centre channel and even if there is no left or right DSP speaker.
Note When DSP5500 is a master this menu operates the boundary
settings for any DSP5500 or DSP5500C in the system which is configured
to be left or right. D6000 ignores this menu.
To change the system boundary setting:
1. Press the w or e menu key until the wall cursor display shows. The
master display will momentarily show
FrEE
This allows you to ask the DSP5500 what its wall setting is without
changing it.
To change the setting:
1. Make sure that you can see the wall cursor display on the master:

2. Press either the n or s menu key. The display will change to
boun.
and the sound will change in balance.
3. Press either the n or s menu key. The display will change to

and the sound will change in balance. This setting may be better for
corner, recessed or under-TV positions.
In this menu you are also offered two choices for use with associated
subwoofers.

slave speakers is a DSP5000.
Centre-channel options
The following two adjustments will appear on the master if the ‘Cen.y’
option is selected in Config or if the speaker has been set to Type 6. It
appears on the master – whether or not it is a centre. A DSP5000C (or
other Meridian Digital loudspeaker) which is configured as a centre
responds to these menu settings.
Using the centre boundary control
The centre boundary control is like the system boundary control, but it can
be operated independently of other speakers in the system.
To change the centre boundary setting:
1. Press the w or e menu key until the centre boundary display shows.
The master display will momentarily show the centre equivalent of the
system ‘FrEE’ setting:
C.FrE.
2. Press either the n or s menu key. Choose from:
C.bou. equivalent to the system ‘boun.’ setting.
C.Sb1 equivalent to the system ‘Sub.1’ setting
C.Sb2 equivalent to the system ‘Sub.2’ setting
C.Cor. equivalent to the system ‘Corn.’ setting.
Using the centre tilt-offset control
The centre tilt-offset allows the centre to be permanently dimmer or
brighter in balance to the other speakers (or 565 decoder outputs) in a
system. It is intended to help you match the sound of the centre to the left
and right main pair.
To change the centre tilt-offset:
1. Press the w or e menu key until the centre tilt-offset display shows.
The master display will momentarily show
C.t.

Connecting DSP5500
Four types of connection must be made to the DSP5500:
• power (see page 12)
• digital audio (see page 44)
• communications (see page 45)
• RS232 to a computer (see page 47)
You will need to plan the connections with the installation you wish to
achieve in mind. It is best to do this while deciding where to put the
DSP5500s, as this decision may affect the positioning of the rest of your
system, and the way in which you connect it. The decision as to which
speaker should be master is also dependent on both positioning and
connections.
The following sections will explain in detail the options open to you.
Remember that your Meridian dealer is chosen for his expertise in this
area. If in doubt, you can always refer to him.
DSP5500 User Guide
Connecting DSP5500

Connectors
The connection sockets on the back panel of the DSP5500, and their
uses, are as follows:
• Comms Output A DIN connector which is used to send information on
to the DSP5500 slave or to a 565 Digital Surround Decoder.
NEVER connect an audio DIN lead to this socket.
• Comms Input A DIN connector which is used to exchange information
with other Meridian components
NEVER connect an audio DIN lead to this socket.
• D1 The first digital input, using a coaxial cable
• D2 The second digital input, using a coaxial cable
• D OUT A digital output which is selected by the DSP5500 to pass on a
signal to the other DSP5500. This means that the slave only needs to
have one digital input connected.
• AC The lower panel contains the power supply, and should already be
adjusted for your local supply voltage – check the labelling. The panel
contains a 3-pin IEC power inlet plug, with a power switch and integral
fuse holder.
• RS232 A standard serial connection for a computer
Where to put the master
The master has more connections made to it than the slave has, since it
is the speaker which is directly connected to any other Meridian products
in the system (for example, a 602, 603, or 607, or any Multiroom
components). It is therefore sensible to put it closer than the slave to the
sources, for the sake of tidiness. You should now be able to decide where
the master will be, and whether it will be a left or a right speaker.
Routing cables
Do not route the DSP5500 cables any nearer to TV or radio antenna
cables than is necessary. Try to keep any excess cable lengths coiled up,
as far from any tuner or television receiver as possible.
Where possible, use a dedicated AC power outlet for each DSP5500. In
any case, try not to use the same outlet group for any tuner or TV.
DSP5500 is a digital audio product, and its use involves distributing digital
audio signals. This is a new field, and it is important to follow our
instructions. Incorrect distribution of digital audio could lead to radio
interference, noticeable errors, or unnecessarily reduced sound quality.
Correct distribution will give you the best sound it is possible to have. You
may be able to use the cables we supply.
AC connection
Before connecting any unit to the AC supply, check that it is adjusted to
the correct voltage for your supply.
IMPORTANT: DO NOT MAKE CONNECTIONS OR INSERT OR
REMOVE PLUGS WHILE THE UNIT IS CONNECTED TO THE AC
SUPPLY AND SWITCHED ON.
1. Connect the unit to the AC power supply with the cord provided
• Each DSP5500 should be connected to an approved AC outlet, using
the cord provided
• If at all possible, adapter or extension accessories should not be used,
even if they are of an approved type
DSP5500 User Guide
Connecting DSP5500

• If a power-line filter is to be used, try to use a permanent type, and be
sure that it is approved to the standards of your territory and that it
retains the grounding
WARNING: DSP5500 must be grounded.
Connection using M5- and S5-leads
Many systems will require only the supplied composite M5- and S5-leads.
If these are not appropriate, further information can be found in the
section starting on page 45.
To get a CD player working with the DSP5500s, proceed as follows:
1. Locate the cable marked with ‘S5’. This is a DIN + Phono to DIN +
Phono lead, about 6m long.
2. Connect one DIN plug to the Comms Input socket and the
accompanying phono plug to the D1 socket on the slave DSP5500.
3. Connect the other end to the Comms Output socket and the D OUT
socket of the master.
This completes the interconnection of the DSP5500 pair. Now:
4. Locate the cable marked with ‘M5’. This is a DIN + Phono to DIN +
Phono lead, about 8m long.
5. Locate the end with the 180° DIN and phono plug. Connect this DIN
plug to the Comms Input socket and the phono plug to the D1 socket
on the master.
6. At the other end of this cable, locate the phono plug and connect it to
the digital output of the CD player.
Note Getting this far should provide you with audio, and further
connections will give you control of any Meridian products in your system.
For connection of Meridian Comms, see page 45.
DSP5500 User Guide

Digital audio connections
Note A digital audio connection will be made into the D1 input if you use
the M5- and S5-leads supplied as directed in the section starting on page
45.
Digital audio has to be conveyed to both DSP5500s in the installation.
This can be done directly from your source to each DSP5500 if
• the source has multiple outputs, or
• you are using a splitter device
Normally each digital audio source is connected only to the master; the
signal from the selected source is then passed from the D OUT socket of
the master, via the S5-lead, to the D1 socket of the slave.
Digital connections are made to the master DSP5500:
• directly from the digital outputs of up to two sources such as CD, DAT,
DCC, MD, or the Meridian 604 digital FM tuner
• from the digital output of an analogue-to-digital converter such as the
Meridian 607. A converter like this can be used to process the signals
from all your analogue sources (for example, the output of a
conventional preamplifier)
• from the digital output of a digital processor or digital control unit such
as the Meridian 562 or 601
• from the digital output of a Multimedia computing device
Digital connections should be made using high-quality 75Ω screened
cable. For advice on the right type of cable to use, we suggest you
consult your dealer and the manual supplied with the source equipment.
Meridian has a range of suitable digital interconnects available as
accessories. We advise you not to use cables intended for analogue
connection, since usually these have neither the necessary degree of
shielding nor the 75Ω impedance which is required. Cable intended for
UHF applications (for example, antenna down-lead) is also unsuitable,
since it does not shield adequately in the 1–30MHz region.
Warning We strongly recommend the use of well-screened precision
coaxial cable. Certain ‘audiophile’ cables are not screened. Screened
cable will minimise RF interaction with your system. Unscreened cables
for digital connections may cause illegal levels of RF interference.
The DSP5500 has two coaxial digital inputs, D1 and D2. The M5- and S5leads provided, which will be sufficient for the great majority of
installations, connect to the D1 input and the D OUT output.
You will need to provide custom cables if
• you wish to use D1 and D2, or
• you are wiring a Multiroom installation, or
• you require cable lengths different from those provided

Hum
Hum is normally only to be expected with analogue sources. Check the
grounding of the analogue preamplifier. See the handbook supplied with
your preamplifier for help.
Clicks with digital sources
If clicks appear in the sound when the system is switched to a digital
source, the two most likely reasons are as follows:
1. If clicks only occur when the source is running (playing), the problem is
due to error correction or transmission failure. First check the condition of
the disc or tape. If the player is a Meridian 207, 208 or 602, look for a
flashing Error light. Check the integrity of the connections between the
digital audio source and the DSP5500. Are you using good 75-ohm cable?
DSP5500 User Guide
Help
50
2. If clicks occur randomly with the source selected but stopped, the
problem may be the result of loss of lock due to gross electrical
interference. Find out whether there is an appliance elsewhere in the
house causing the disturbance (e.g. central heating, a pump or a fan). If
there is, suppress it.
Meridian CD does not respond
1. Check that all connections between the master speaker and the
Meridian CD player have been made correctly
2. Make sure that the whole system is set up in either 200 mode or in 500
mode.
Note All Meridian products must be in the same mode. 200 or 600-Series
products can only work in 200 mode and if you intend to incorporate these
in a DSP5500 system, the speakers and any 500-Series components
must be put into 200-mode (normally Type 2).
3. Make sure that the DSP5500 has been set up so that this source is
Comms type ‘1C’ – see page 37.
4. Make sure that the Comms address corresponds in DSP5500 and in
the CD player (normally ‘1A’) – see page 37.
504, 204 or 604 does not respond
1. Check that all connections between the master and the 504/204/604
have been made correctly. If a 204/604 is the only other Meridian
equipment in the system you will need an SP5 adapter to allow the
M5-lead to connect to the socket marked CD on the 204/604.
2. Check that a 204 is fitted with software of an adequate level. DSP5500
requires version 204.A or later. To see the version, press Mode * Set
on the front panel of the 204 when the unit is not in Standby. Version
numbers count 1–9, then A–Y. If the software in your 204 is earlier
than 204.A, your dealer will be able to obtain an up-to-date EPROM
and fit it. Operating code can always be updated.
2. Make sure that the whole system is set up in either 200 mode or in 500

Communications not working between DSP5500 and
other Meridian products
If you have this problem, check the connections carefully. The section
starting on page 45 deals with this in some detail. Then check the
following:
• Are you using a B-lead or P-lead instead of a B1-lead?
• Are you using a Q-lead instead of a Q1-lead?
• Are you using an A-lead with a Meridian tuner? The A-Lead is not
suitable for this; you should request a B1-Lead.
If you cannot see an obvious problem, connect the Comms one product at
a time. If you cannot solve the difficulty refer to your dealer, but first note
the software versions fitted in all of your Meridian items.
To find out the software version for a Meridian product:
1. Press its Display key while it is in Standby. (If it does not have a
display key, use a 209 remote control or refer to the manual supplied
with the product).
Note your connections carefully.
Note Make sure that the whole system is set up in either 200 mode or in
500 mode.
Note All Meridian products must be in the same mode. 200 or 600-Series
products can only work in 200 mode and if you intend to incorporate these

Type 1 setup, Meridian 500 series system using 562
The Meridian 562 allows simple control and routing of analogue and digital
sources. All connections from sources are made to 562 which then sends
a single digital feed to the DSP5500s. Type 1 sets the DSP5500 as a left
master, so you will need to make the other a right slave, or adjust left/right
on both speakers.

Type 2 setup, Meridian CD as preamp (via 607), 204
connected
The Meridian compact disc player range includes players with built-in
preamplifiers, such as the 207 and the 208. To use the analogue inputs
of these units, it is necessary to put a 607 (or similar) A/D converter
between the fixed output of the preamp section and the D2 input of the
DSP5500. It is possible to control one of the previously mentioned CD
preamp combinations and a Meridian FM tuner using Type 1. Type 1 sets
the DSP5500 as a left master, so you will need to make the other a right
slave, or adjust left/right on both speakers.
