Safety Precautions
For safety reasons please read the following instructions and the enclosed
Important Safety Information carefully before attempting to connect your
subwooferunittothemains.
PlugFittingInstructions(UKonly)
The cord supplied with this appliance is factory fitted with a 13A mains plug
fitted with a 3A fuse inside. If it is necessary to change the fuse, it is
important that a 3A one is used. If the plug needs to be changed because it
is not suitable for your socket, or becomes damaged, it should be cut off
and an appropriate plug fitted following the wiring instructions below. The
plug must then be disposed of safely, as insertion into a 13A socket is likely
to cause an electrical hazard. Should it be necessary to fit a 3-pin BS
mains plug to the power cord the wires should be fitted as shown in this
diagram. The colours of the wires in the mains lead of this appliance may
not correspond with the coloured markings identifying the terminals in your
plug. Connect them as follows:-

3. Low Frequency Cut-Off
This is used to adjust the point at which the crossover will
separate the low frequencies being used by the subwoofer
from the higher frequencies played by the rest of the
system. Raising the Low Frequency Cut-Off will increase
the frequency range that the MS308 will reproduce.
Lowering the Low Frequency Cut-Off will limit the range of
frequenciesreproduced.

If switched to auto, the subwoofer will remain in standby
mode until a signal is detected at the input. The unit will
then automatically switch itself on. It will then automatically
return to standby mode if no input signal is present for
approximately 5 minutes. With the switch in the 'ON'
position the unit remains permanently on as long as the

Importantnote
ConnectingyourLoudspeakers
Always unplug all A.C. powered components before
making any loudspeaker or component connections. This
will avoid the risk of electric shock or damage to your
equipment.
Do not compromise the performance of your system by
using inferior quality cables! Mordaunt-Short recommends
that high quality cables of 16 gauge or higher be used.
Yourprofessionaldealerwillgiveyougoodadvice.
Observing polarity is of the utmost importance while
connecting your loudspeakers. Ensure that the red (+)
terminals on your amplification system are connected to
the red (+) on the speaker, and black (-) on your
amplification system to black (-) on your speakers.
Positioning your Loudspeakers
Properly placed, your Mordaunt-Short Premiere
loudspeaker system will provide an excellent, wholly
satisfying sound. However, with each room varying in size,
dimension and layout, it will be necessary to experiment
with the placement of your loudspeakers in order to gain
optimumperformance. Atypicalset-upisshownbelow.
If your speakers are wired incorrectly they will be out of
phase and sound hollow and indistinct, with a weak bass.
Re-check your connections for correct polarity and reverse
theconnectionsifnecessary.

Note
MS302FrontLeftandRightLoudspeakers
Your MS302 loudspeakers come with mounting holes to fit
Omnimount 25 Series wall mountable speaker brackets.
Detailsareavailableatwww.omnimount.com.
Mordaunt-Short brackets are also available, contact your
dealerorwww.mordaunt-short.co.ukformoreinformation.
Your MS302 front left and right speakers should be placed
equidistant to the left and right of your screen far enough
apart to ensure good stereo imaging. If they are too far
apart or too close to the corners of the room they will sound
distracting and distant. It may be desirable to experiment
with the 'toe-in' of the units (angling them towards the
listening position) to optimize the front speaker soundstage
andimaging.
MS308Subwoofer
The positioning of your MS308 subwoofer will affect the
quantity and also quality of the lower frequencies of the
system. Locating the subwoofer near a wall will increase
the bass response of the speaker. If it is placed too near to
a corner however, the overall effect may be too 'boomy'.
Due to the low frequency nodal characteristics of the room,
the response will change as it is placed a little closer, or
further away from the listening position. Adjusting the rear
panel controls (as explained in previous sections) will also
affect the sound, so the answer is to experiment and find
the position and settings that provide a good balance
between low frequency amount and definition across a
rangeofsourcematerial.
MS302RearLeftandRightLoudspeakers
Your MS302 rear left and right speakers should be situated
roughly at listening height and facing into the listening
position. It is suggested that they are wall mounted or
alternativelyplacedonsuitablespeakerstands.
MS304CentrechannelLoudspeaker
Your MS304 centre channel speaker needs to be
positioned directly above or below your screen, facing the
listeningposition.

Final System Setup
Once all wiring connections are complete and you have
positioned your Premiere loudspeakers, turn on your
amplification system and run the relevant Level Calibration
Sequence to establish the correct individual volume level
foreachspeakerchannel.
Your MS308 subwoofer comes with feet and spikes
which must be fitted to space the down-firing speaker unit
thecorrectdistancefromthefloorforoptimumoperation
The spikes attach to the bottom of the feet (as shown
belowleft).
Finally, play some test material and make final adjustments
to the Active Sub Frequency Cut-Off point that allows the
best overall integration within the system, sounding neither
too boomy, or overly thin. After this step, It may be
necessary to run the Level calibration again to make final
levelchecks.
There are eight pilot holes on the bottom of the speakers.
The feet are located and secured here with the wood
screwssupplied(belowright). Levelasrequired.
Running In
Your new loudspeaker system will require approximately
10 hours of normal use to allow the components to settle
into their working routine and reach their optimum
performance.

Taking care of your loudspeakers
By far the most common cause of loudspeaker failure, and
CabinetCare
one that is understandably not covered by guarantee, is
damage to the voice coils caused by amplifier overload.
This is generally due to the common belief that if a speaker
is rated at more than the amplifier's output rating, there is
no chance of blowing that speaker.............
Cabinets should be dusted and lightly polished as required.
Do not use solvent based cleaners, as they may damage
the cabinet surface. Do not expose the cabinets to strong,
direct sunlight, high temperatures, high humidity or allow
them to become wet.
This is not the case!
A relatively small amplifier (i.e. 20 watts) can damage
speakers like these by "clipping" the signal, a symptom
identified by lack of detail in music and distortion. If this
occurs TURN IT DOWN! If you don't want to blow up your
speakers but want louder sound, please purchase a more
powerfulamplifier.
