EPOS ELS User Manual

Amplifiers with power outputs
between those specified will
generally be adequate, although
more powerful amplifiers can be
used if care is taken to avoid
overdriving the loudspeakers.

Use the volume control with
discretion, and reduce the level
immediately if 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. They may also
cause damage to the
loudspeakers if 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
power amplifier operating beyond
its capacity.

Do not make or break
connections to the amplifier when
it is turned on!

POSITIONING

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.

Thank you for purchasing Epos loudspeakers.
Please take a little time to read these brief notes, which will
help you get the best from your loudspeakers.

Series Loudspeakers

POWER REQUIREMENTS

Some experimentation may be
necessary to establish the ideal
position within your listening
room. Begin by positioning the
loudspeakers about 20cm (8”)
from the rear wall and gradually
move them out a little until you
achieve the best balance
between bass weight and
definition. Avoid placing the
loudspeakers in corners because
this may cause un-welcome
colouration of the midband
frequencies. 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 (8’) 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 stabilise 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.

The best results will be obtained
from the ELS 3 if they are placed
on stands rigidly coupled to the
floor using carpet piercing spikes.
This will help preserve the
outstanding midband clarity
which is a hallmark of Epos
loudspeakers.

Epos stands are available to
match the ELS 3. Please contact
your dealer for further information
or visit the Epos web site:

Ensure that your amplifier is
switched off before you make or
break any connections, as
damage may occur if shorted.

Your Epos loudspeakers are
equipped with high quality
connection sockets with excellent
electrical contact and current
specification.

A set of 4 plugs is supplied with
your loudspeakers. These will
allow you to terminate your
speaker cables. To terminate the
cables, simply remove enough
insulation to allow the plastic

CONNECTION

shroud to fit over the end of your
cable. Make a solder connection
to the plug and screw in the cover
until no bare plug is evident.

Once again, if you are in doubt
consult your Epos dealer, who will
be able to offer this service.

The plugs provided have been
selected to provide a good
electrical connection.

The sockets on the rear of 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
amplifier, while the sockets
marked black should be
connected to the black (or
negative) output terminals on
your amplifier.

Use good quality cable to connect
your loudspeakers to the
amplifier.

 Ensure that the cables from

each speaker are of roughly
equal length

 Do not coil the surplus tightly.

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
of incorrect phasing. This will
cause the bass to disappear and
the stereo image to spread 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,
coloured line or writing on the
positive wire.

Switch on the amplifier 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.
