USER GUIDE

Introduction

This SLx plug-in aerial amplifier is designed to improve picture and sound quality by amplifying
weak UHF and VHF signals.

4G Ready - built-in lter removes interference and channel loss caused by 4G mobile phone signals.

These instructions cover the most common installation options. However, if you need further
advice, please contact our Customer Careline (see overleaf).

Please Note: If used to boost signals from the RF2 output on a satellite receiver you will need to fit a
digital bypass you will also need a TV with an analogue tuner to view the satellite signal.

Boosting the signal to your TV

Standard installation for weak
signal areas

TV

1. Connect the UHF aerial downlead
(typically via an aerial wall socket) to the
INPUT socket of the SLx amplifier.

ANT IN

2. Connect an aerial flylead from the
OUTPUT socket of the SLx amplifier to
the aerial input (usually marked “ANT IN”)
on the back of your TV.

Tuning your TV

Once you have made your connections has been set up switch on your equipment.
Tune the TV to terrestrial television channels and tune any other additional piece of equipment
connected to begin viewing. Consult your equipment instruction manuals for tuning details.

Adjusting the gain level

The plug-in amplifier has an adjustable gain control. The gain level can be adjusted to optimise sig­nal strength. This model can boost the signal by up to 20dB.
Please note: The maximum gain setting will not necessarily give the best picture and sound.
Adjust the gain gradually until you find the setting which gives the best results.

1. Turn anticlockwise to increase the gain level

2. Turn clockwise to decrease the gain level

Troubleshooting

Problems with Digital TV Reception

Typically you will either receive DTT (Digital Terrestrial Television) channels with a clear picture and
sound or not at all.

Sometimes, a weak 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.
Turn the gain level down to minimum and gradually increase the gain to find the best gain level for
a good picture.

Intermittent Connections

Make sure that all coaxial cables are free from twists, kinks and tight bends as this may damage the
inner core of the cable and result in poor picture/sound quality. If you have fitted the coaxial
connector to the cable yourself please ensure that all connectors have been fitted to the cable
tightly (both inner and outer), preferably soldered.
