Additional Features
Dual Inputs – With separate inputs for UHF TV and
VHF (FM and or DAB) Radio and a built-in signal
combiner your signal distribution system can easily
be expanded to include high quality radio signals
in every room.
If you have a long cable run from the aerial to the
booster you can use a masthead pre-amp near
the aerial which the Auto Line-Power will detect and
supply 12V to power it.
All SLx aerial boosters comply with RED
(The Radio Equipment Directive 2014/53/EU).
Introduction
Planning your distribution system -
Choosing a location for the amplier
The 4-way amplier may be tted in any convenient
position the most popular being either the loft or
the sitting room near the main TV. In choosing a
location, consider the following:
a) The amplier needs to be plugged into the
mains, so it must be near a socket.
b) You will need to run cables from the amplier to
each outlet point.
c) You must be able to get the cable from the aerial
to the input of the amplier.
Mounting the amplier -
The amplier is best xed to a wall or other suitable hard
surface, using suitable screws and masonry plugs (not
supplied).The amplier should not be left supported by
its own wiring, nor should it be left resting on a carpet or
other insulating and/or inammable surfaces
and must
be placed where it will not be
smothered by curtains
or other fabrics, etc, or thermal insulation materials in
a loft.
A ventilation gap of at least 25mm should be
left around the front and sides of the unit.

Applications
SLx Boosters incorporate a Class 1 lter to
reduce 4G and 5G interference and are
suitable for digital TV signals Ch 21-48
(470-694MHz) however if you wish to receive
TV on Ch60 you should use an SLx Booster
with IR Bypass. In this case you may need a
Ch 60 lter if you are affected by 4G or 5G
interference.
Installation
Important note: attention is drawn to the
General Safety Precautions Panel above
which contains advice on safe installation
and operation of these products.
Location
Choose a location for the booster from which
it is convenient to run cables from the
antennas and to the system outlets.Typical
examples of suitable locations are a loft
space or a cupboard. In weak signal areas it
is best to keep the aerial cables as short as
possible.
Select a cool, dry location to install the
booster.This means a location where the
ambient temperature will remain between
-10°C and +40°C, and which is free from risk of
dripping or splashing water.
The xing location should allow adequate
access to the equipment for wiring and
maintenance. Clearance of at least 25mm
should be allowed around the left hand
side and top of the unit for ventilation. More
clearance will be needed on the other sides
to allow access for cables.
Fixing
The booster should be xed to a wall or other
suitable hard surface using the keyhole slots
on the back of the housing and suitable
screws and wall plugs, a template is provided
on page 4.
The booster should not be left supported
by its own wiring, nor should it be left resting
on a carpet or other insulating and/or
inammable surfaces.
Signal Connections
Input and output signal connections are
made using IEC coax connectors. Good
quality plugs and digital quality double
screened coaxial cable should be used to
ensure optimum performance from your
booster.
Line Powering
The SLx4 has built-in full line powering which
can be used to provide power to masthead
boosters. When connected to a masthead
amplier, the SLx4 will send the required power
out of the UHF socket up to the masthead
amplier (up to 25mA). Please see your
masthead amplier operating instructions for
more details.
In order to provide a non-interrupted 12V
power supply to the masthead amplier.
it is important to ensure that there is no
equipment between the UHF socket and the
masthead amplier output socket.
If equipment is connected in between,
the booster will not be able to detect the
masthead amplier and so will automatically
not output 12V.
General Safety Precautions
To Prevent Overheating
The recommended clearances and other precautions given in these instructions must be
observed to prevent overheating. In addition, units should not be positioned where they are
likely to become covered by curtains, fabric or insulating material. The amp should not be
left resting on a carpet.
Other precautions
These appliances are not waterproof, they are intended for indoor use only and must not be
positioned where they could be exposed to dripping or splashing water. Objects containing
liquids should not be placed on or near the booster.
To prevent re, make sure the unit and attached cabling is installed well away from naked
ames and other heat sources.
Mains Plug
Your booster is supplied with a standard mains plug already tted, if you need to change
the plug use a competent professional (ELECSA or NICEIC) to make the connection.
If you need to change the fuse use a 3 Amp fuse to BS1362 carrying the ASTA or BSI
approved mark and ret the plastic fuse carrier.
Before Installing Please Note
2
1. Connect your UHF aerial downlead to the
UHF socket and connect your FM/DAB
aerial downlead (if applicable) to the FM
socket on your booster.
2. Connect your TVs and DAB/FM tuners to
any of your booster”s TV sockets in any
combination.
If your TV does not have a built-in Freeview™
receiver you will need to connect your TV to
the booster via a Freeview™ of PVR set top
box.

Troubleshooting
If you experience reception problems after
installing your SLx booster, please see below:
No picture or sound
Is the signal reaching your TV? Check:
- Everything, including the booster is plugged
in and switched on
- Coaxial connections are correctly made
(no braid or foil is touching the inner core
Picture or sound breaking up
- Use the best wideband aerial ideally tted
outdoors
- Use good quality coax cable, poorly
screened cable can pick up noise
- In some cases too much signal can cause
signal break-up which can be solved
by tting an attenuator to the input to the
booster
