About your Meridian Active loudspeakers
These instructions provide information about unpacking, connecting up,
confi guring, and using your Meridian 3100 Active loudspeakers. They apply to the
M3100 left and right loudspeakers, and the M3100HC horizontal centre loudspeaker.
Introduction
Meridian Active loudspeakers represent the fruits of more than 25 years of
continuous development of loudspeakers as musical instruments. The fi nest
materials and state-of-the-art design are combined to create what we believe is the
ultimate range of home loudspeakers.
Drivers
Each 3100 loudspeaker uses either one or two high-effi ciency long-throw custom
drive bass units.
Each treble unit is a very high quality 25mm (1”) Meridian piston using a doped
fabric dome. It is extremely well matched to the woofers, and also tonally very
compatible with the other drivers employed in the Meridian range.
Power amplifi ers
The speakers are driven by multiple independent high-power, low-feedback power
amplifi ers.
The active electronics provides huge performance advantages. The amplifi ers are
tailored to suit the direct drive to the drive units, providing very low output
impedance, excellent damping, and bass extension far beyond what is possible in
passive designs.
The whole electronic assembly is supplied from a substantial toroidal transformer
feeding high-quality, audiophile-grade capacitors.
Cabinet
Each 3100 loudspeaker is carefully designed from bonded aluminium panels, with
internal bracing and damping to give incredibly low levels of cabinet resonance,
resulting in low coloration and excellent mid-range transparency.

Unpacking your speakers
Before you begin installation you should ensure that your Active 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 Active loudspeakers, or to any other
component in your system, while the AC power supply is connected and switched on.
Components
Each Active loudspeaker system is supplied with the following components:
•
One power cord per speaker.
•
Meridian analogue audio lead.
•
Pack of four feet/spikes.
If any of these items is missing please contact your dealer. We suggest that you
retain the packaging carefully for maximum protection in transit.
Removing the grilles
M3100: 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.
M3100HC: The grille is held on by pegs. Gently pull from the sides and then top and
bottom to remove it.
Note: The speakers are designed to be used with their grilles fi tted.
Cleaning the speakers
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.
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 fi rst. Do not
use any polish containing a solvent; these can cause crazing of the surface.

The balanced connection should be made with a high-quality XLR lead. The
unbalanced connection should be made with a shielded audio phono lead,
preferably with a double-screen copper lap construction.

You can connect two M3100 loudspeakers directly to the analogue outputs of an
analogue preamplifi er, such as the Meridian G01 Control Unit or Meridian G02

You can use a single M3100HC as a centre speaker in a Meridian surround system
based on a Meridian G61, G68AD, G68ADV, or G68AXV Digital Surround Controller.
• Connect the speaker to the CENTRE analogue output, as shown in the
illustration.
The G68AXV provides balanced analogue outputs so you can achieve higher quality
by connecting the balanced CENTRE output to the balanced input of the M3100,
using a suitable XLR lead.

The Meridian G91A DVD Player can be confi gured as a surround processor, allowing
you to connect it directly to up to fi ve M3100 loudspeakers, and an optional
subwoofer, such as the Meridian DSW1600, to create a complete compact surround
system.
• Connect the LEFT and RIGHT analogue outputs from the G91A to the main front
M3100 loudspeakers.
• Connect the SURR L and SURR R analogue outputs from the G91A to the rear
M3100 loudspeakers.
• Connect the CENTRE analogue output to the centre M3100HC loudspeaker.
• Optionally connect the SUB analogue output to an active analogue subwoofer.
• Confi gure the G91A DVD Player to Type 6; see the G Series DVD Player Installation
Guide.

Troubleshooting
Indicator on front panel not lit
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 front panel indicator 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.
Unit goes quiet when played hard
A temperature sensing system on the 3100
loudspeakers prevents overheating of the
electronics. The sound will revert back to
normal volume when the speaker has cooled.
Drive units move when the speaker is
switched on or off
This is normal as the speaker active electronics
settle.
