User Manual
This booklet contains information on the Epos Mi series loudspeaker range, with the exception of the M sub-woofer which
has its own manual.
POWER REQUIREMENTS
Amplifiers with power outputs between those noted in the loudspeaker specifications will generally be adequate,
although more powerful amplifiers could be used if care is taken to avoid over-driving the loudspeakers.
Always use the volume control with discretion, and reduce the level immediately should the loudspeakers begin to distort.
Amplifiers capable of less than 25 Watts per channel output are best avoided because they will restrict the dynamic
range. Such amplifiers may also cause damage to the loudspeakers if they are driven beyond their capability in an
attempt to obtain high volume levels.
The clipping distortion produced when an amplifier is driven beyond its normal output capability can be very destructive. A
powerful amplifier operating well inside its capability will generally be less likely to damage your loudspeakers than a
lower powered amplifier operating beyond its capacity.
NOTE: Do not make or break loudspeaker connections to the amplifier when it is turned on.
POSITIONING
Epos loudspeakers are designed to be positioned as specified. Space should be left behind the loudspeakers to allow
proper operation of rear firing reflex ports and to ensure establishment of good stereo image depth. Some
experimentation may be necessary to establish the ideal position within your listening room.
Begin by placing the loudspeakers about 20cm from the rear wall and gradually move them out a little at a time until you
achieve the best balance between bass weight and definition.
Avoid placing the loudspeakers in corners because this may cause a doubling of low frequency output. Try to leave at
least 40cm of space between each loudspeaker and the nearest side wall.
The optimum stereo performance will be achieved when the speakers are positioned 2.5 metres or more from the listener
and about the same distance from one another. Turning the speakers in very slightly towards the listener often helps to
stabilize the stereo image.
Speakers ‘image’ best if you can just see the top face of the speaker from your listening position. Remember, there is no
absolute right or wrong - if it sounds good, it is good.
QUICK CONNECTIONS
Switch off your amplifier whenever making connections.
Take your speaker cable and connect the positive terminal on the amplifier left channel, marked + or coloured red, to the
positive terminal on the left loudspeaker. The negative terminal on the amplifier left channel, marked - or coloured black,
must be connected to the negative terminal on the left loudspeaker. Repeat connections for the right channel.
If you choose to bi-wire or tri-wire your loudspeakers, please read the detailed section on page 3.
LISTENING
Switch the amplifier on with the volume turned down low. Check that the bass and treble sounds come from both
speakers. If not, switch off and remake the connections.
RUNNING IN
Your new loudspeaker system will require a total of approximately 24 hours of normal use to allow the components to
settle into their working routine and reach their optimum performance.
ALWAYS REMEMBER
?lower the volume before making any adjustments to the system (e.g. switching amplifier inputs or raising or lowering
pickup arm).
?switch off the amplifier before checking or making any changes to any connections in the system.
NEVER
?try to find out how loud the system will go.
?use your loudspeakers for any other purpose other than domestic listening.

DISCLAIMER
The 4mm plugs used on modern hi-fi speaker cables should never be inserted into European mains sockets even though
they may fit. Needless to say, this is pointless and can be fatal if tried. Make sure that young members of the family are
prevented from ever doing this.
STANDS
For loudspeakers designed for use on stands, best results will be obtained if the stands are rigidly coupled to the floor
using carpet piercing spikes. Floor-standing loudspeakers should also be coupled to the floor using the carpet piercing
spikes supplied. This will help preserve the outstanding mid-band clarity which is a hallmark of Epos loudspeakers. Epos
has designed its own stands to suit the M5i and M12i.
The floor-standing and centre channel models are supplied with their own support plinth. Contact your dealer for further
information or visit the Epos website ww.epos-acoustics.com
SPIKES
Four threaded spikes are provided with each floor-standing speaker, together with individual locking nuts. These should
be screwed into the metal inserts in the bottom of the cabinets, or into its plinth. Once these are adjusted to correct the
level of the speaker and stop it from rocking, tighten the locking nuts, so as to prevent the spikes from coming loose.
Adjusting the front spikes higher will tip the speaker up and can give sonic benefits.
CONNECTION
Ensure that your amplifier is switched off before you make, or break, any connections, because damage may occur to
your amplifier if shorted.
Your Epos loudspeakers are equipped with insulated nickel plated binding posts with excellent electrical contact and
current specification. The posts are connected to the individual drivers as denoted on the rear panel label.
Removable metal links enable the loudspeaker to be conventionally wired with a single cable, bi-wired or bi-amped,
(tri-wired or tri-amped where applicable). These techniques often bring benefits in terms of increased clarity and
definition.
If you are in any doubt consult your dealer or visit www.epos-acoustics.com
BI-WIRING/TRI-WIRING
Bi-wiring involves the use of two pairs of speaker cables between your loudspeakers and amplifier. Tri-wiring requires
three pairs of speaker cables. If you wish to bi-wire your M5i, M8i or M12i speakers, or tri-wire your M16i or M22i speakers
it is essential that you first unscrew all the binding posts and remove the metal links that join them together. Store them
safely for possible future use. Once the links are removed, the drive units will be electrically separate and should be
connected to the driving amplifier with individual high quality cables, as shown.
