Meridian DSP loudspeakers represent the fruits of more than 25 years of continuous
development of loudspeakers as musical instruments. The finest materials and stateof-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 highprecision 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.
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.

Power amplifiers
The speakers are driven by multiple independent high-power, 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.
Meridian Comms
Meridian DSP loudspeakers are part of the Meridian family of advanced digital,
analogue, and video components, and these incorporate a sophisticated
communications link, to allow you to control any combination of units using a single
remote, and ensure that they will work together as a fully integrated system.

Removing the grilles
The following table gives details of the digital audio connections:
Digital connections
DSP3100: The grille is held tightly in place by the side metal plates. Gently pull it
from the top edge, taking care not to scratch the high-gloss lacquer, then pull it
gently from the sides and then bottom to remove it.
Use this connection
To connect to this
DIGITAL INPUT 1,
DIGITAL INPUT 2
A digital source, such as a digital sound processor, digital
preamplifier, CD player, or DVD player
DSP3100HC: The grille is held on by pegs. Gently pull from the sides and then top
and bottom to remove it.
DIGITAL OUTPUT
A second (slave) DSP loudspeaker, using an S5 lead.
The digital connections should be made with high-quality 75Ω screened cable.
Suitable cables are available from Meridian. We do not recommend using analogue
audio cables, which do not have adequate shielding or the correct impedance, or
cables intended for UHF applications, as these do not provide adequate shielding in
the 1–30MHz region.
Note: The speakers are designed to be used with their grilles fitted.
Master and slave
When two 3100 loudspeakers are supplied as a
pair, one speaker is preconfigured as Left Master
and the other as Right Slave. This allows you to
set up a 2-channel system without any further
configuration:
Left Master
Right Slave

Cleaning the speakers
COMMS INPUT
Greasy marks should be removed from the metal surfaces by light rubbing with a
slightly damp cloth and a trace of proprietary glass cleaner. Do not use any other
solvent or abrasive based cleaners.

RS232
The serial port of a PC, to control the DSP loudspeaker using a
computer. For more information see the Meridian Web site,
http://www.meridian-audio.com.
On black speakers, small marks on the lacquer surface can usually be removed by
treating with Black Turtle Wax Color Magic. Do not use any coarse polish such as
Auto Colour restorer, and always test any polish on a non-visible area first. Do not
use any polish containing a solvent; these can cause crazing of the surface.
The DIN Comms and BNC Comms connections are equivalent; use whichever is
appropriate for the leads supplied with your other Meridian equipment.

You can create a complete system by connecting a pair of 3100 loudspeakers directly
to a digital source. The 3100 loudspeakers include volume, balance, and tone
controls allowing you to control the system using an MSR+ (not provided).
Because the 3100 speakers are preconfigured for use in a two-channel system, no
further configuration is necessary.
• Connect the DIGITAL OUTPUT and a COMMS socket from the Meridian source or
control unit to DIGITAL INPUT 1 and the COMMS input on the DSP loudspeaker
labelled Left Master, using the M5 lead supplied.
• Connect the DIGITAL and COMMS outputs from the master DSP loudspeaker to
DIGITAL INPUT 1 and the COMMS input on ther DSP loudspeaker labelled Right

If your system includes more than two Meridian 3100 loudspeakers you will need a
511 S-patch box (available separately) to link together the S5 leads from each
speaker, as shown above. Note: This does not apply to the 861, which includes a
built-in patch box.
• Use the comms part of an M5 lead to connect one of the COMMS sockets on the
Meridian Surround Processor to the 3100 loudspeaker you have chosen as the
master (typically the centre speaker).
• Use the audio part of the M5 lead to connect the 3100 loudspeaker to the
appropriate digital output on the Meridian Surround Processor.
• Connect the COMMS output from the master 3100 loudspeaker to one socket on
the 511 using an S5 lead.
• Link all the other 3100 loudspeakers together in pairs using S5 leads, as shown in
the illustration.
• Connect each pair of 3100 loudspeakers to the appropriate digital output on the
Meridian Surround Processor, using an S5 lead. The other part of the S5 lead is
used to distribute the COMMS from the 511 to each pair of DSP loudspeakers.
You will then need to configure the master speaker as described in the section
CONFIGURING overleaf.

Choosing a standard setting
Unless you are using a pair of 3100 loudspeakers in a 2-channel system, you will
need to configure them as described in this section.
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:
Alternatively you can configure the speaker as a slave, with the D2 input used for all
sources, as follows:
• Press the green &gt; (Play) key on the remote
repeatedly until the display shows:

Using the DSP loudspeakers as a control unit
Changing the display
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 display information about the current settings on the 8character front-panel display.
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.
Switching on and 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
By default the 12 sources are available.
In addition, three coloured indicators show status information.
To change the displayed information
• Press Display.
Pressing Display steps between the options: Source and volume, Meridian source
display (dashes if not present), Audio format, and Blank.
The audio format display shows PCM, Data, or MHR followed by the frequency, or
NL (not locked).
Status indicators
The display includes the following status indicators: Red: Master loudspeaker,
Yellow: 88kHz or 96kHz input, and Green: Clipping.
Adjusting the volume
To change 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.
• Press the red A or V keys on the remote.
As standard, all the sources are set to select the D1 digital input.
As you adjust the volume setting the display will show
the current volume level. For example:
To switch to standby
To silence or restore the sound
• Press Off on the remote.
• Press Mute on the remote. The display will show:
The loudspeakers will switch to standby

Adjusting the sound
Troubleshooting
To change the treble or bass
Display on front panel not lit
The 3100 loudspeakers provide sophisticated treble and bass controls, to allow you
to adjust the broad balance of the system to correct for the acoustics of your
listening room, or for a misbalanced recording.
The controls are more subtle than conventional tone controls, and take advantage
of digital signal processing techniques to provide a more natural adjustment of the
frequency response.
• Press Function &lt; or Function &gt; until the display shows the current treble or bass.
• Press Function A or Function V to change the treble or bass.
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 &plusmn;10db in
0.5dB steps. Normally settings between +1.0 and -2.0 will give the most natural
results.
The bass control allows you to adjust the bass response in the room by &plusmn;5dB in 0.5dB
steps. Normally settings between +3.0 and -2.0 will give the most natural results.
To change the absolute phase
You can change the absolute phase of the signal, to compensate for signals which
are out of phase, giving an unnatural-sounding bass.
• Press Function &gt; or Function &lt; until the display shows the current phase.
• Press Function A or Function V to change the phase.
To change the balance or axis
The balance control of the DSP loudspeakers uses digital signal processing to
compensate for an off-centre listening position by delaying and diminishing the
sound in one speaker, thus 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.
• Press Function &lt; or Function &gt; on the remote until the display shows the
current balance or axis.
• Press Function A or Function V to change the balance or axis.
The display shows the direction and position of the listening position.
There are 32 balance steps in each direction.
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.
Check the following:
• There is AC power connected to the socket
on the back of the 3100 loudspeaker.
• The power switch on the back panel of
the 3100 loudspeaker is turned on.
If the display will still not illuminate, check any
fuses in your power supply and the fuse in the
inlet of the 3100 loudspeaker. If these are all
intact, contact your dealer.
Remote not working
Check the following:
• The battery in the MSR+ remote.
• See if the 3100 loudspeaker has been set
up as not controller in the Meridian
Configuration program. Note: This may
be deliberate by your dealer.
Unit goes silent when played hard
and displays ‘Hot‘
The 3100 loudspeakers have a temperature
sensing system on board, which prevents
overheating of the electronics. The sound will
continue when the speaker has cooled.
There is radio interference
The 3100 loudspeaker is a digital audio and
computing device which has been designed to
very high standards of electromagnetic
compatibility.
If this equipment does cause or suffer from
interference to/from radio or television
reception then the following measures should
be tried:
• Reorient the receiving aerial (or antenna)
or route the antenna cable of the receiver
as far as possible from the DSP
loudspeaker and its cabling.
• Ensure that the receiver uses well-screened
antenna cable.
• Relocate the receiver with respect to the
DSP loudspeaker.
• Connect the receiver and this product to
different AC outlets.
• If the problem persists contact your dealer.
Drive units move when the speaker is
switched on or off
This is normal as the speaker active electronics
settle.
Configuring the 3100 loudspeaker
does not have any effect
Make sure that you are configuring the 3100
loudspeaker used as the master digital
loudspeaker in the system. This determines the
configuration of all digital loudspeakers in the
system.
Unit stays in standby
• Check that it is connected correctly.
• Turn the system on from another Meridian
product in the system.
Only the master loudspeaker plays
• Check the S5 cables are connected
correctly.
Sound is odd or mono
• Check that the 3100 loudspeakers are
correctly configured as Left and Right
respectively.
The green indicator flashes or stays
on
This indicates that 3100 clipping is occurring.
Brief flashes indicate occasional clipping which
will not be audible.
If the indicator stays on for long periods this
may indicate a fault in the configuration of
your system, and you should contact your
Meridian dealer.

be deliberate by your dealer.
Unit goes silent when played hard
and displays ‘Hot‘
The 3100 loudspeakers have a temperature
sensing system on board, which prevents
overheating of the electronics. The sound will
continue when the speaker has cooled.
There is radio interference
The 3100 loudspeaker is a digital audio and
computing device which has been designed to
very high standards of electromagnetic
compatibility.
If this equipment does cause or suffer from
interference to/from radio or television
reception then the following measures should
be tried:
• Reorient the receiving aerial (or antenna)
or route the antenna cable of the receiver
as far as possible from the DSP
loudspeaker and its cabling.
• Ensure that the receiver uses well-screened
antenna cable.
• Relocate the receiver with respect to the
DSP loudspeaker.
• Connect the receiver and this product to
different AC outlets.
• If the problem persists contact your dealer.
Drive units move when the speaker is
switched on or off
This is normal as the speaker active electronics
settle.
Configuring the 3100 loudspeaker
does not have any effect
Make sure that you are configuring the 3100
loudspeaker used as the master digital
loudspeaker in the system. This determines the
configuration of all digital loudspeakers in the
system.
Unit stays in standby
• Check that it is connected correctly.
• Turn the system on from another Meridian
product in the system.
Only the master loudspeaker plays
• Check the S5 cables are connected
correctly.
Sound is odd or mono
• Check that the 3100 loudspeakers are
correctly configured as Left and Right
respectively.
The green indicator flashes or stays
on
This indicates that 3100 clipping is occurring.
Brief flashes indicate occasional clipping which
will not be audible.
If the indicator stays on for long periods this
may indicate a fault in the configuration of
your system, and you should contact your
Meridian dealer.
