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, visit www.dtg.org.uk

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 
care line on

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.
