Introduction
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.
Digital Signal Processing
Digital Signal Processing, or DSP, is a technique
pioneered by Meridian in hi-fi products for achieving
extremely accurate reproduction of audio signals using
high-precision mathematical processing.
DSP allows sophisticated processing to be performed
without any of the cumulative noise or degradation
that inevitably occurs, even with high-quality analogue
circuitry. In addition, the signal improvement techniques
incorporated in the Meridian DSP loudspeakers would
be virtually impossible to implement in the analogue
domain.
The Meridian DSP loudspeakers take advantage of
DSP for several different functions:
• To remove timing variations from the incoming digital
signals (de‑jittering).
• To split the audio frequency band between bass, midrange, and treble drivers (crossover).
• To perform filtering or adjustment of the frequency
response; eg treble or bass.
• To provide volume control to 48-bit precision.
• To provide digital protection of the loudspeakers
against high-level low-frequency transients.
• To perform electronic equalisation.
If you are using the Meridian DSP loudspeakers with a
digital source, such as CD or DVD, the signals remain
in digital form until the last possible stage.
DSP loudspeaker drivers
Each DSP loudspeaker uses multiple high-efficiency
long-throw custom bass drive units.
Each treble unit is a very high quality 25mm (1")
Meridian piston in a short horn, using an aluminium
dome with a silver voice-coil. It is extremely well
matched to the woofers, and also tonally very
compatible with the other drivers employed in the
Meridian range.
Power amplifiers
The speakers are driven by multiple independent highpower, low-feedback power amplifiers. The combination
of idealised magnetic design, careful star earthing, and
very fast output devices gives the amplifiers extremely
low noise, high detail, and fast bass.
The whole electronic assembly is supplied from
substantial toroidal transformers feeding high-quality,
audiophile-grade capacitors.
Cabinet
Each DSP loudspeaker is carefully designed with
internal bracing and damping to give incredibly low
levels of cabinet resonance, resulting in low coloration
and excellent mid-range transparency.
The DSP5200 and DSP5200HC are constructed
using veneered plywood, braced and resin damped to
produce an ultra-rigid cabinet.
The DSP5500, DSP5500C, and DSP5500HC are
constructed using thick veneered MDF sides bolted
through a 1.5mm steel plate onto the main cabinet,
giving extremely low levels of cabinet resonance and
excellent bass-mid isolation.
The DSP7200 cabinet is fabricated from curved
pressure-laminated panels, using multiple layers of
selected woods and metal to achieve high stiffness
and damping. Its narrow tapered shape gives optimum
Introduction
dispersion over a wide listening area. Each cabinet
stands on three adjustable machined feet which can be
fitted with spikes or skids.
remote, and ensure that they will work together as a
fully integrated system.
Mounting options
The Meridian SpeakerLink connectors provide both
Meridian Comms control and two-channel balanced
digital audio in a single convenient SpeakerLink lead.
In addition to the main vertical speakers, designed for
use as the left/right speakers in a system, each model
includes a single horizontal centre and/or a single
vertical centre, designed for use as the centre speaker
in a surround system.
Meridian Comms also allows you to extend your hifi system into two or three rooms, with the ability to
control the sources in one room from the controller in
another room.
The DSP5200HC, DSP5500HC, and DSP7200HC
are horizontal centre versions, designed for use either
above or below a television.
The following page shows two recommended
configurations based on the Meridian DSP
loudspeakers to illustrate the flexibility of Meridian
components.
The DSP5500C is a vertical version, designed for use
as a centre speaker, and it uses fully shielded drive
units so they it be placed next to a television without
interference.
Meridian High Resolution (MHR)
All Meridian DSP loudspeakers support Meridian High
Resolution (MHR), to allow you to connect to other
MHR-compliant Meridian products to take advantage
of high-rate audio sources, and provide the additional
benefits of lower jitter and improved sound quality on all
sources.
MHR is a proprietary secure encoding format that uses
encryption and anti-copy methods to provide a secure
copyright protection environment, and allow the secure
transfer of audio streams within a Meridian-only system
for playback only.
Meridian Comms
Meridian DSP loudspeakers are part of the Meridian
family of advanced digital, analogue, and video
components. These incorporate a sophisticated
communications link, called Meridian Comms, to allow
you to control any combination of units using a single
Available accessories
Other applications, and some advanced features, may
require one or more of the following accessories, which
can be purchased from your Meridian dealer:
• MSR+ remote.
• Interconnecting leads.
• AC11 SpeakerLink Hub, to allow interconnection
between newer products with SpeakerLink
connectors, and products with Meridian BNC Comms
or Meridian DIN Comms connectors.

Introduction
DSP5200 and
DSP5200HC
DSP5200 and DSP5200HC
This chapter explains how to unpack and install the DSP5200 and
DSP5200HC, and gives specifications.
DSP5200 and
DSP5200HC
Unpacking
Before you begin installation you should ensure that
your DSP loudspeakers are the correct voltage for your
local AC supply. If they are not, do not try to install
them, and contact your dealer.
You should not make any connections to the DSP
loudspeakers, or to any other component in your
system, while the AC power supply is connected and
switched on.
Care when unpacking
Take great care when unpacking or repacking the DSP
loudspeakers that you do not put undue pressure on
the face containing the drive units, as they may be
damaged if pressed.
Components
Each pair of DSP loudspeakers is supplied with the
following components:
• The DSP loudspeakers complete with grilles.
• A hex wrench (3mm) for the drive units.
• Eight screw-in feet with retractable spikes (DSP5200
only).
• Eight rubber bumpons (DSP5200HC only).
• One power cord per speaker.
• This user guide.
If any of these items is missing please contact your
dealer. We suggest that you retain the packaging
carefully for maximum protection in transit.
Caution
Meridian Audio has taken every care in the design,
assembly, finishing and packing of this product. Some
models include a high-gloss finish, which is achieved by
painting up to five coats of polyester lacquer onto the
plywood, each one hand polished.
Due to the product size and high technology cabinet
construction, small marks on the lacquer surface may
be visible when unpacked. These small marks can
usually be removed as described in Cleaning, page 43.
It is the nature of all lacquer finishes to shrink over
time. This is unavoidable and may result in cabinet joint
lines becoming visible.
Meridian Audio has supplied products using lacquer
finishes for many years and we are confident that
when carefully used your product will return a lifetime’s
enjoyment.
To fit the feet (DSP5200 only)
The feet ensure that the loudspeakers have a stable
base, and can be adjusted to allow for uneven floors.
Use the spikes for carpeted floors; they are designed
to penetrate the pile without damaging or flattening the
carpet. Retract the spikes for solid floors.
Each DSP loudspeaker needs four feet, fitted as
follows:
• Insert the spike into the foot so that the nut engages
in the hexagonal recess in the bottom of the foot,
and screw each spike into the threads on the bottom
of the loudspeaker. Do not fully tighten the lock nuts
at this stage.
• On solid floors retract the spike so it does not extend
below the foot cap.
• When all four feet have been fitted, carefully set the
DSP loudspeakers upright in their playing positions
and remove the rest of the packaging.
• On carpeted floors, adjust the spikes until the
speakers are stable, and then tighten the lock nuts
using the feet as wrenches. If you need additional
length on the spikes you can remove the feet and
use the spikes and lock nuts on their own.
DSP5200 and
DSP5200HC
To fit the rubber bumpons
(DSP5200HC only)
• Attach four bumpons to the underside of each
speaker, using the self-adhesive pads.
Tightening the drive units
The DSP loudspeakers typically take about two weeks
of normal use for the drive units to settle. It is therefore
recommended that you tighten the mounting bolts
on each drive unit every few days during this period.
Tighten the bolts in symmetrically opposite pairs using
the 3mm hex wrench supplied.
You should then check and if necessary re-tighten the
drive units every few years.
Removing the grilles
The grilles are deliberately designed to fit tightly to
avoid vibration during operation, and they should
be removed using the following procedure to avoid
damaging the loudspeaker.
The grille consists of elastic material stretched tightly
over a plastic ring. The plastic ring includes two
indentations at the three o‘clock and nine o‘clock
positions, which you can locate by gently depressing
the grille fabric.
Hold the ring by one of the indentations by depressing
the grille fabric with your thumb, and then wiggle the
ring forwards until it comes free of the speaker. The
grille fabric is very resilient and any depressions will
soon disappear.
Note: On no account attempt to remove the grille with
a hard object, or attempt to lever it out from the outside
edge, as you will damage the edge of the speaker
surround and the grille itself.

Positioning the digital loudspeakers
To obtain the best sound
For best results adjust the position of the loudspeakers
while listening to music.
If possible, have the most acoustically absorbent wall in
the room behind the front speakers. Ideally have each
DSP loudspeaker at least 0.5m (20") from a corner,
and position them approximately 0.25m (10") from the
wall.
If you are using a DSP loudspeaker as a centre
channel, place the speaker centrally between the main
left-right pair and, if possible, arrange for the treble
units of the three speakers to be approximately the
same height.
You can configure the frequency response of the DSP
loudspeakers to compensate for a position close to a
wall or corner; see To adjust the frequency response,
page 38.

Using the DSP
loudspeakers
Using the DSP loudspeakers
In systems with a Meridian preamplifier or control unit all of the functions
of the DSP loudspeakers, including volume, treble, and bass, are
operated via the controller. For more information refer to the user guide
for the preamplifier or control unit, and you can ignore this chapter.
The DSP loudspeakers can also be connected directly to up to two
digital sources to create a complete, minimum system. This chapter
provides step-by-step instructions for operating the DSP loudspeakers in
a system with no Meridian preamplifier or control unit.
28
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.
To select a source
• Press the appropriate source key on the remote; eg
Radio.
This will bring the DSP loudspeakers out of standby,
and the displays will show the currently selected source
and volume setting.
For example:
Radio 65
Initially all the sources are set to use the SpeakerLink
digital input. To configure all sources to use the co-axial
input, configure the speaker as M.Coax or S.Coax;
see To choose master or slave and the primary
connector, page 34. To configure an individual source
to use a different input see To configure a source,
page 37.
To switch to standby
• Press Off on the remote.
The displays will show:
. 29
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.
Pressing Display steps between the following options:

Using the DSP
loudspeakers
Adjusting the volume
The DSP loudspeakers adjust the volume in precise
steps of 1dB, where 9dB is equivalent to doubling the
loudness, and can be varied in the range 1 to 99dB.
When you first connect power to the DSP loudspeakers
the volume is set to 65, which is similar to the midway
position of the rotary volume control on a conventional
preamplifier.
To change the volume
• Press the A or V volume keys on the remote.
As you adjust the volume setting the display will show
the current volume level.
For example:
Radio 55
To mute (silence) the sound
• Press Mute on the remote.
The display will show:
Muted To restore the sound
• Press Mute again on the remote.
31
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.
The bass control allows you to adjust the bass
response in the room by ±5dB in 0.5dB steps.
Normally settings between +3.0 and -2.0 will give the
most natural results.
The controls are more subtle than conventional
tone controls, and take advantage of digital signal
processing techniques to provide a more natural
adjustment of the frequency response.
To change the absolute phase
You can also change the absolute phase of the signal,
to compensate for signals which are out of phase,
giving an unnatural-sounding bass.
If you have a Meridian Surround Controller these
functions are performed via the surround controller.
To change the treble
• Press Function < or Function > until the display
shows the current treble.
For example:
Tre.+0.0
• Press Function A or Function V to change the
treble.
The treble control tilts the frequency of the response
over the entire frequency range to make the sound
brighter or dimmer. It can be adjusted between ±10db
in 0.5dB steps. Normally settings between +1.0 and
-2.0 will give the most natural results.
To change the bass
• Press Function < or Function > until the display
shows the current bass setting.
For example:
Bass+0.0
• Press Function A or Function V to change the
bass.
• Press Function > or Function < until the display
shows the current phase.
For example:
Phase +
• Press Function A or Function V to change the
phase.
32
Using the DSP
loudspeakers
Changing the listening position
The balance control of the DSP loudspeakers uses
digital signal processing to compensate for an offcentre listening position by delaying and diminishing
the sound in one speaker, thus effectively shifting the
speaker’s image back.
The axis control allows you to adjust the optimum
listening height of the DSP loudspeakers, like a
balance control operating in the vertical plane.
If you have a Meridian Surround Controller these
functions are performed via the surround controller.
To change the balance
• Press Function < or Function > on the remote
until the display shows the current balance.
For example:
Bal. <0>
• Press Function A or Function V to change the
balance.
The display shows the direction and position of the
listening position.
For example:
Bal. 12>
• There are 32 steps in each direction.
To change the axis
• Press Function < or Function > on the remote
until the display shows the current axis setting.
For example:
Axis -1 • Press Function A or Function V to change the
axis.
The axis can be adjusted between 3 and -2, where
0 corresponds to the axis of the treble unit. Usually a
listener will be below that position, so we recommend
settings of -1 or -2.

Configuring the DSP
loudspeakers
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.
Once you have configured the DSP loudspeakers you will probably
never need to change the configuration, unless you alter the equipment
connected to your system at a later stage.
34
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:
• Release the remote key.
The display will show:

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 34.
To configure the DSP loudspeaker
• Turn off the DSP loudspeaker, using the power
switch on the back panel.
• Turn on the power again while holding down the 0
