Introduction
The SLxB series
amplifiers are
All SLxB amplifiers
have an integrated
by-pass designed
to allow the user to
control digital satellite
receivers from a
second TV without
additional equipment
apart fron a Link
device and a digital
satellite or compatible
universal remote
control.
For added safety
The amplifiers are
easy to install and
fully automatic in
operation, meaning
that no user
adjustment is required.
The low running cost
permits continuous
operation.
the SLxB series has
built in short circuit
protection on each
individual output.
Should a short circuit
be detected the SLxB
amplifier will only
shut down the output
with the short circuit;
the other outputs will
continue to function
as normal.
designed to improve
the picture and
sound quality of TV
and FM radio signals
and distribute these
signals around your
home.

SET UP 3:
Satellite Receiver Signal Distribution
1. Connect your UHF aerial downlead into the
VCR’s UHF aerial input. If you do not have a
VCR, plug the UHF aerial downlead into the
satellite receiver’s UHF aerial input and ignore
all further references to VCRs.
5. Connect an output lead from the satellite receiver
RF2 output to your aerial amplifier IN UHF socket.
UHF TV,VCR playback and satellite receiver signals
will now be available to your main TV and to any TV
you now connect to the amplifier TV sockets. For FM
connection see SET UP 1.
2. Connect the VCR RF output lead to the aerial
input on the satellite receiver.
To operate your digital satellite receiver from one of
the connected TVs you will now need to install a
Link device such as the SLx Link.
3. Connect the satellite receiver via the Scart
outputs to the VCR and TV.
4. Connect an output lead from the satellite
receiver RF1 output to the aerial input on
your main TV.
N.B. It may be necessary to retune the output
channel of your VCR when used with a satellite
receiver. Consult your VCR user guide.
Troubleshooting
Similarly blocking and even a completely blank
screen with no sound can result if the input
signal to the set top box is too high. The digital
cliff refers to the rapid change from the picture
and sound being perfect, to disappearing
altogether.
If you are still experiencing reception
problems after the installation of your
SLxB Aerial Amplifier, please refer below.
Analogue Terrestrial TV
When interconnecting equipment and to get the
best carrier to noise, place the digital terrestrial
television set top box as the first item in the
signal path followed by any video or satellite
receiver.
Snowy Picture
A faint, grainy or snowy picture is generally caused
by a weak signal. Normally the TV transmitter will
be a long way away. A possible improvement could
be made by reducing the aerial downlead losses,
installing a high gain aerial and by adding a low
noise masthead amplifier or signal booster. In a
small number of cases, a snowy picture can also be
caused by a TV signal that is too strong.
Fitting a high gain wideband roof aerial may also
improve the reception and signal quality.
Digital signals are generally immune to ghosting
or multipath reflections.They remain perfectly
receivable under conditions where an analogue
signal would suffer ghosting.
‘Herringbone’ Pattern
‘Herringboning’is generally caused by too strong a
TV signal or by a local high power transmitter such
as CB, amateur or taxi radio.Your TV sound may be
affected as well as the picture. Using an attenuator
will reduce the gain of an aerial signal and improve
the overall picture.
For specific help with DTT reception problems,
Digital Satellite Television
With digital reception, a weak signal or
incorrectly aligned dish will cause the picture
and sound to block or disappear. Check both the
alignment of the dish and skew angle of the LNB.
Digital Terrestrial Television
Unlike analogue TV signals that can still be
viewed under weak signal strength conditions,
with digital terrestrial signals blocking/freezing
and/or loss of digital picture and sound can be
caused by insufficient digital signal and carrier to
noise ratio.
Intermittent Connections
Make sure all RF cable to connector joints are
tight (both inner and outer) including all flyleads
and outlet plate connections.
