Positioning
AV Positioning
The front, and in some cases rear, floor standing and stand mount speakers should be positioned approx 6 - 9 feet apart (1.8m
- 2.5m) and start with them about 10 inches (25cm) from the wall.
When playing music, if the sound is too bass heavy or there is bass boom from the room, then try moving the loudspeakers
slightly further away from the wall(s). If this is not possible, then try the supplied port bungs (not included in the MR Centre).
Refer to Page 5.
The MR Centre should be positioned so that it is pointing at you, in your viewing position, and at approximate ear height. If it is
below or above ear height, use some rubber feet (small feet supplied) to angle it slightly.

2 Channel Positioning
For use in a 2 channel system, the listening position and the loudspeakers should form an equilateral triangle. The speakers
should be positioned approximately 6 - 10 feet (1.8 - 3m) apart. They ideally need to be between 8 - 18 inches (20 - 45cm) away
from the rear and 3 feet (1m) from the side walls.
Experimentation is strongly advised when initially setting up your speakers, as environments and personal preference differ
with each installation. If there is not enough bass, for example, then try moving your speakers closer to a wall. The opposite, if
there is too much bass. Also see the information on page 5 refering to Port Bungs. If you are loosing stereo imaging, try ‘toeing’
them in slightly. The sound should appear to originate from the centre point between the speakers, not the actual speakers
themselves.
Spike Fixing
The Monitor Reference Series floor standing loudspeakers, come with spikes. These enhance the acoustic performance of the
loudspeaker and should be used where possible. The spikes can be found in the packaging of the MR4 and MR6 only.
BEWARE. The spikes are very sharp, and could cause injury if care is not taken when handling them. Please ensure
there are no hidden wires under the carpet, or trailing mains leads that could be damaged by the spikes.
1.
Carefully place the cabinet on it’s top or back to fit the spikes.
2.
Screw the spikes into the threaded inserts on the bottom of the cabinets.
3.
Carefully turn your speaker back over and check that it is evenly balanced. If uneven, you can adjust the height in the
appropriate (lowest) corner by unscrewing the spike slightly. This operation may need to be repeated a several times to
ensure your cabinet is completely level. When you are happy with the balance of the cabinet, tighten the locking nut on
each spike.

Wiring configurations
Single Wire
For the MR1 and MR Centre, there are only one pair of
terminals (as in illustration opposite). This means it is
only possible to single wire these speakers.
Single Wire
The MR2, MR4 & MR6 all have two pairs of terminals.
By running one pair of cables (one positive and one
negative) you will be single wiring them.
When single wiring these speakers, you must leave the
terminal links in.
Bi-Wire or Bi Amp
By running two pairs of cables (two positive and two
negative) from a single pair of terminals on your amp,
you will be bi-wiring them.
Some AV amplifiers support bi-amping. This is very
similar in process to bi-wiring, except the two pairs of
cables will not be joined at the amplifier end to a single
set of terminals, they go to two pairs of terminals. Biamping is also achieved by using two stereo amplifier.
By bi-wiring/ bi-amping them you will get a cleaner,
more smooth sound with tighter mid and more
controlled bass.
When bi-wiring these speakers, you must remove the
terminal links. Failure to do so will result in damage
to your amp.

Monitor Reference Series
Port bungs
WARNING: Care must be taken not to insert the port bungs too far into the port, as this may result in the foam bung
being lost inside the cabinet.
If the loudspeaker is to be installed in a small room, typically 9 sqM ( 80 sqFT), or a room known to reproduce accentuated bass
response, it may be desirable to fit port bungs. However, experimentation is recommended with positioning of the loudspeaker
in the room prior to fitting. To optimise performance from the loudspeaker it is important to ensure the loudspeaker is not
positioned too close to a wall or near the corners of a room (refer to the suggestions on pages 2 and 3).
If the positioning of the loudspeaker is predetermined by room aesthetics or layout, or you find you have accentuated bass,
please read point 1 for the MR1 & MR2 and point 2 for the MR4 & MR6.
1.
Where bookshelf/ stand-mount speakers (MR1 & MR2) are to be sited in close proximity (less than 8 inches/ 20cm) to a
rear wall (such as on a bookshelf, wall mounted, positioned in a cabinet or on a stand close to a wall), we recommend
experimenting with fitting port bungs into the ports. This will reduce the bass ‘boom’ sometimes termed as “overhang”,
and assist the loudspeakers to reproduce their best performance under these environmental conditions. ‘Boom’ is
generally caused when bass energy from the loudspeaker ‘excites’ room modes and causes an accentuation at a particular
frequency, or number of frequencies.
2.
Where floor-standing loudspeakers (MR4 & MR6) are to be sited in close proximity (closer than 18 inches/ 45cm) to a
rear wall, we recommend experimenting fitting the port bungs. This will reduce the bass ‘boom’ sometimes termed as
overhang and assist the loudspeakers to reproduce their best performance under these environmental conditions. This
is caused when bass energy from the loudspeaker ‘excites’ room modes and causes an accentuation at a particular
frequency, or number of frequencies.
3.
When fitting port bungs the overall bass extension will not be reduced, however bass energy/ output around the port tuning
frequency will be reduced. This has the effect of reducing bass ‘boom’ while increasing bass clarity and apparent agility.
Experimentation is highly recommended.

depending on room and tastes.
Note:- cable lengths should not exceed 10 metres to avoid interference from other electrical appliances.
2. LFE Input (RCA Type)
This input is to be used when connecting the subwoofer to an AV amplifier/ receiver. When using the LFE input, the crossover
frequency dial is not used. This is due to the crossover function being controlled by the AV amplifier/ processor to which
it is connected.
3. 12 Volt Trigger Input ~ Centre Pin = +12Vdc
For external power control from AV amplifier/ receiver to the MRW10. Monitor Audio recommend using this function and a
lead is supplied. A 12 volt signal is supplied by the AV amp/receiver and tells the MRW10 to turn on from standby mode.
This allows a more accurately controlled auto on/off function, and is far more energy efficient. When using the 12v trigger,
the Mode Switch (8) can be in either position, for it to function correctly.
4. Crossover Frequency Control
The crossover frequency control only operates when using the RCA stereo input (1) and is used to set the upper frequency
limit (low pass) of the subwoofer. The crossover control should be set in accordance with the size or bass output of the main/
satellite speakers. When using the Bronze Series speakers, set this to between 50 - 100Hz (depending on additional speakers).
Experimentation is advisable.

5. Volume Control
This control allows the level or volume to be adjusted in order to achieve a balanced overall sound. To get the balanced
sound a selection of familiar music or film excerpts will need to be played. Start with the volume at minimum and increase
the level control until a balanced sound is established.
If using an AV processor or AV receiver amplifier, the system can be adjusted by the test tone function within the set-up
features. (Refer to the set up section in the AV processor or AV receiver amplifier user guide.) When the subwoofer is
correctly set-up, you should not be able to identify its location easily in the room.
6. Bass Switch
This switch tailors the bass response of the subwoofer to your tastes. There are three settings: Music, Movies and Impact.
Movie mode provides a relatively flat response down to 35Hz. Music mode is -2dB down on Movie mode but goes lower, all
the way down to 30Hz. Impact mode is +3dB up on Movie mode and comfortably goes down to 40Hz.
7. Phase Control Switch
The Phase Control is used to synchronise any delay between the subwoofer and main/ satellite speakers. When the subwoofer
is in phase with the main/satellite speakers the sound should be full bodied. Sit in a normal listening position whilst adjusting
the phase switch. Help from another person may be required. When set correctly the location of the subwoofer should be
almost undetectable. Experimentation is advised in order to achieve optimum results. However it should be noted that in most
cases the phase control switch should be set to 0 degrees.
8. Power Mode Switch with On-Auto Facility
With the switch in the ‘On’ position, the subwoofer is permanently switched on under all conditions. In the ‘Auto’ position the
subwoofer will automatically switch on when an input signal is received. It will remain on for a period of 15 minutes without
receiving a signal before switching into standby mode until a signal is received once more.
Additional Notes on the Auto On Function
When using the auto on feature, the subwoofer will “lock” onto the input it was activated by. In most cases, when using either
stereo or LFE input connection this will not matter. However, if using both stereo and LFE connections, you will not be able to
toggle between inputs until the subwoofer has entered standby. This can be done manually by turning it off and on again, or
by letting it time out (15 mintues) before changing the inputs over.
9. Mains Power Switch
The Mains Power Switch should be switched to the ‘Off’ position when the subwoofer is unused for extended periods. The
switch must be in the ‘On’ position for the subwoofer to function.
WARNING: Due to the mains switch being located on the rear panel, the apparatus must be located in the open area with
no obstructions to access the mains switch.
10. IEC Mains Power Connector/ Fuse Location
The subwoofer is supplied with a two-pin mains input socket for connection to the mains supply. Use ONLY the appropriate
IEC mains lead provided with the product. Also fitted is an external mains fuse. If this fuse blows during operation a spare
fuse is provided within the fuse holder for replacement. If you wish to change the fuse, you can do this by removing the
IEC mains lead and carefully levering out the original fuse from its holder below the IEC mains input socket (10a). If the
fuse blows again it is advisable to seek help from an authorised service agent. DO NOT attempt to re-fit a further fuse as
this could result in serious damage to the amplifier unit.
11. Mains Voltage Selector
This is factory set to your country’s mains voltage specification. Do not attempt to adjust this as this may lead to
permanent damage to the product and even the risk of fire. There is a clear plastic cover over the selector to prevent
accidental adjustment.
The LED on the top of the cabinet indicates whether the unit is in standby mode or operational. It will be illuminated red when
in standby, and green when operational.

Positioning / Initial Set Up of MRW-10
Leave the subwoofer unplugged from the mains until the installation procedure is completed. The subwoofer should now
be sited in the most suitable position. If placed in a corner of the room there may be excessive bass ‘boom’. Once a desirable
position is achieved it is important to check if the cables are long enough to reach comfortably without being under tension. The
optimal control settings will depend entirely on your system configuration. For initial trials set the controls as follows:
Volume Control
Should be set to minimum
Frequency Control
Should be set to the 12 o’clock position
Phase Control
Should be set to zero degrees
Power Mode Switch
Should be set to ‘On’
By Pass Filter Switch
Should be set to the ‘On’ for AV and ‘Off’ for 2 channel listening.
Input connections can be made at this stage before the power is connected to the subwoofer.
Never connect or disconnect any leads with the subwoofer connected to the mains.
Set Up
Once the input cables are connected and the controls are set in accordance with the initial set-up procedure above, the
subwoofer can be connected to the mains power supply and switched on at the mains power switch.
•
For use with an AV amp/ receiver (product with sub woofer output) run the auto set up on the AV amp. Check the settings
it has supplied and carry out fine adjustment if necessary. This may include adjusting the gain or crossover frequency on
the AV amp or level on the sub woofer. The crossover frequency should be similar to that in the table on page 6.
•
Play some familiar movies to double check it integrates with the system and carry out any adjustments to the levels or
crossover frequency if necessary.
•
For use with a stereo amp (product without Sub woofer output), set the crossover frequency control in accordance
with the table on page 6. The level may need to be adjusted so that it integrates at all levels. Further fine-tuning of the
crossover frequency may be required.
The Phase Control can now be set, please refer to page 7 for further information. It is important to try a variety of music and
film excerpts with which you are familiar in order to obtain the optimum overall settings.

Trouble Shooting
Should you experience any technical, or set-up problems with your subwoofer please check the Trouble Shooting Guide below:
My subwoofer will not turn on/ no power.
•
Is the LED illuminated on the unit? If not, then check your mains lead is properly connected both at the subwoofer and at
the mains outlet. Also check the fuse of the mains plug (where fitted) and also the fuse in the subwoofer. See page 8 for
further information on changing the fuse and it’s location.
•
Is the LED red? If so, you have power going to the unit. It could be that there is no signal.
•
Is there a signal going to the subwoofer? If there is a signal present, is the Power Mode Switch in the Auto or On position,
and the source is turned on? Try adjusting the volume level of the source and try the switch in the ‘On’ position.
If it still does not turn on/ power up, please contact your local dealer/ distributor or Monitor Audio immediately.
No sound from subwoofer.
•
Is the LED red or green? If it is red, then the unit hasn’t actually turned on, see suggestions above. If it is green, then your
unit is powered up and turned on. Check further suggestions below.
•
Are the signal leads connected correctly? Check these. If possible, check with a second, known to be working set.
•
Is the volume level just very low?
If it still does not output a signal, please contact your local dealer/ distributor or Monitor Audio immediately.
