POWER REQUIREMENTS

Ampliers with power outputs between those noted in the loudspeaker speci­cations will generally be adequate, although more powerful ampliers 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.

Ampliers capable of less than 10 Watts per channel output are best avoided
because they will restrict the dynamic range. Such ampliers 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 amplier is driven beyond its normal
output capability can be very destructive. A powerful amplier operating well
inside its capability will generally be less likely to damage your loudspeakers
than a lower powered amplier operating beyond its capacity.

NOTE: Do not make or break loudspeaker connections to the amplier when it

is turned on.

POSITIONING

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 at least
1m of space between each loudspeaker. Gradually move them out a little at a
time until you achieve the best balance between bass weight and denition.

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.

All Epos K-Series loudspeakers have been designed to produce a broad

listening area. However, the optimum sound balance and stereo image will
be enjoyed if your ear level, when seated for listening, is approximately in line
with tweeter. So, if you can just see the top of the speaker that will be ne. If
the ideal is not attainable, or convenient, listening beyond this range will also
be enjoyable.

Remember, there is no absolute right or wrong - if it sounds good, it is good.

QUICK CONNECTIONS

Switch off your amplier whenever making connections.

Take your speaker cable and connect the positive terminal on the amplier
left channel, marked + or coloured red, to the positive terminal on the left
loudspeaker. The negative terminal on the amplier left channel, marked - or
coloured black, must be connected to the negative terminal on the left loud-

speaker. Repeat connections for the right channel.

If you choose to bi-wire your loudspeakers, please read the detailed section

on page 3.

LISTENING

Switch the amplier 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.

ALWAYS REMEMBER

Lower the volume before making any adjustments to the system (e.g. switch­ing amplier inputs or raising or lowering pickup arm) and switch off the ampli­er before checking or making any changes to any connections in the system.

DISCLAIMER

The 4mm plugs used on modern hi- speaker cables should never be inserted
into European mains sockets even though they may t. 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 oor using carpet-piercing spikes.
Floor-standing loudspeakers should also be coupled to the oor using the car­pet-piercing spikes supplied. This will help preserve the outstanding mid-band
clarity which is a hallmark of Epos loudspeakers.

The oor-standing models are supplied with their own support plinth.

SPIKES

Four threaded spikes are provided with each oor-standing speaker, together
with individual locking nuts. These should be screwed into the metal inserts

in the bottom of the 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
benets.

CONNECTION

Ensure that your amplier is switched off before you make, or break, any con­nections, because damage may occur to your amplier if shorted.

Your Epos loudspeakers are equipped with insulated gold - plated binding
posts with excellent electrical contact and current specication. 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. These techniques often bring benets in
terms of increased clarity and denition.

If you are in any doubt consult your dealer.

BI-WIRING

Bi-wiring involves the use of two pairs of speaker cables between your loud­speakers and amplier. If you wish to bi-wire your speakers, it is essential that
you rst 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 amplier with individual high quality cables.

WARNING

The sockets on the loudspeaker marked red (on the right side as you look
at the loudspeaker rear panel) should be connected to the red (or positive)
output terminals on your amplier, while the sockets marked black should be
connected to the black (or negative) output terminals on your amplier.

Use good quality cable to connect your loudspeakers to the amplier. Ensure
that the cables from each speaker are of roughly equal length and that any
surplus is gathered in a loose hank. Do not coil the surplus tightly.

PHASE

If the cables are not connected to each left and right speaker in the same way,
i.e. black and red reversed in one, the effect will be incorrect phasing. This
will cause the bass to disappear and the stereo image to move away from the
middle to a position outside the two speakers.

Correctly wiring the polarity of the speakers will restore the image to between

the speakers and provide proper bass. Most speaker cables have a polarising

mark, such as a raised bump or writing on the positive wire.

RUNNING IN

Epos loudspeakers require a little gentle use to allow their working compo­nents to settle into their proper working condition.

Do not be concerned if your new speakers sound aggressive and lacking in
low-frequency authority when you rst begin to use them. Things will quickly

improve.

Allow between twenty four and forty eight hours of normal use before you
expect your new loudspeakers can be expected to perform at their best.

OPTIONAL GRILLES

Your K-Series loudspeakers are not supplied with the optional protective
grilles. If you wish to purchase these grilles, please contact your dealer or
Epos directly.
