http://technical.philex.com
The SLx range of aerial
amplifiers from Philex
is designed to improve
picture and sound
quality by amplifying
weak UHF, VHF and FM
radio (selected models
only) signals and
distributing the signal
to multiple locations
around the home. The
SLx6 can also be used
to distribute a VCR,
Digital Television and
Sky™/ Sky+™ signal
around the home.
Designed with style,
sophistication and value
in mind, the SLx range
is the preferred choice
for both the professional
aerial installer and the
home user wanting
to get the very best
performance from their
AV equipment.
We have integrated
the very latest
in digital-ready
signal amplification
technology, the very
best in UK-designed
product styling and
highest levels of safety
to produce a class-
leading product.
With full instructions
and wall mounting
template, installing the
SLx6 aerial amplifier is
both quick and easy.

If you are still experiencing
reception problems after
installing the SLx6, please
refer to the trouble-
shooting guide below:
No picture or sound
No signal is reaching your
television due to a possible
break in the aerial signal path.
Ensure that all equipment has
been switched on (including
the SLx6 amplifier) and that all
coaxial connectors have been
fitted correctly.
Snowy picture
Your signal strength is still too
weak. Ensure that your aerial is
positioned correctly (pointing
at your local TV transmitter).
For details of your local
television transmitters, visit
www. bbc.co.uk/reception.
Ageing aerials become
corroded by the weather,
which may need to be
replaced. Also check that the
position of the aerial has not
been mis-aligned by weather,
birds, or loft activity.
‘Herringbone’ pattern
‘Herringboning’ is generally
caused by too strong signal or
possibly by local high power
transmitters such as CB, amateur
or taxi radios. Your TV sound
may be affected as well as the
picture. Use a signal attenuator
(available from your local
electrical retailer) to reduce the
gain of your aerial signal and
improve your picture. If you are
located very close to your local
television transmitter, point
your aerial at an alternative
transmitter in order to receive a
more suitable level signal.
Problems with DTT
Unlike analogue terrestrial
television, it is not possible to
view DTT channel under weak
signal strength conditions.
Therefore, typically you will
either receive DTT channels
with a clear picture and sound
or you will not receive any
channels at all.
Sometimes, an insufficient
digital signal can cause
occasional blocking, freezing or
complete loss of picture. Some
roof aerials may not be suitable
for digital terrestrial television.
Ensure that you have fitted a
suitable wideband, high gain
aerial to help improve signal
quality to a suitable level for
clear DTT reception.
Blocking, freezing or complete
loss of picture can also occur
when a digital signal is too
strong.
If your signal is too strong then
connect your DTT receiver
directly to the UHF aerial
downlead, then connect the
SLx6 amplifier to your DTT
receiver output followed by
your remaining equipment. If
the signal is still too strong, fit
a signal attenuator between
the aerial downlead and DTT
receiver to help reduce the
signal strength.

Problems with satellite
television
If you are experiencing any
problems with your satellite
television picture, check that
all cables and connectors have
been fitted correctly. If the
problem persists it is probably
due to the dish alignment or a
temporary problem with the
channel transmissions. Please
contact your local satellite
dealer if the problem persists.

Line Powering
The SLx6 has built-in full
line powering which can be
used to provide power to
masthead amplifiers. When
connected to a masthead
amplifier, the SLx6 will send
the required power out of
the
IN UHF
socket up to the
masthead amplifier. Please
see your masthead amplifier
operating instructions for
more details.
It is important to ensure
that there is no equipment
between the
IN UHF
socket
and the masthead amplifier
output socket in order to
provide a non-interrupted
12V power supply to the
masthead amplifier. When
connected after any
equipment, the amplifier will
automatically detect that no
masthead amplifier is present
and so will not output 12V.
If you are experiencing problems using the
SLx1 amplifier, please contact our customer

retailer for recycling advice.
Additional Features
Full output socket
The SLx6 is equipped with a
FULL
output socket, which
carries a signal of the same
strength as your aerial
downlead. If you wish to
connect further televisions
in your home you can
connect another aerial
amplifier by connecting
an aerial fly-lead from the
FULL
output of the SLx6
to the input of another
amplifier.
If you are not using the
FULL
output socket it is
important that this output
is terminated using the
supplied terminator. Failure
to do this can result in poor
system performance.
Short circuit protection
For added safety the SLx6
has
built-in short circuit
protection
. Should a short
circuit be detected, the
amplifier will only shut
down the amplifier in order
to prevent any possible
damage. Should this occur,
all outputs will be switched
off but the power LED will
remain lit.
To reset the system following
a short circuit, simply remove
all outputs and inputs, switch
off the amplifier and remove
the power cable from its
socket for approx 30 seconds.
You should then reconnect
the amplifier outputs one by
one until you can find which
output is causing the short
circuit.
