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  
‘Herringboningis 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.
