SLx low noise, high gain aerial amplifiers The SLx range of Aerial Amplifiers from Philex are designed to improve picture and sound quality by amplifying weak UHF, VHF and FM radio signals. They can also be used to connect up to eight TVs to a single aerial outlet without losing signal strength to each TV.
Designed with style, sophistication and value in mind, the SLx range is the choice for both the professional aerial installer and the home user wanting to get the very best from their AV equipment.
We have integrated the very latest in digital-ready signal amplification technology, the very best of UK-designed product styling and the highest levels of safety to produce a class-leading product that is crammed with additional features not usually associated with equipment in this class.
With full instructions, wall mounting bracket and template, installing and operating an SLx Aerial Amplifier is both quick and easy.
Setting up the SLx1 1-way Aerial Amplifier METHOD 1 TV Signal Reception
UHF (TV)
1. Connect your UHF aerial downlead to the ANT input of the SLx1. 2. Connect the aerial flylead from the TV output of the SLx1 to the aerial input on your TV.

METHOD 2 Video Cassette Recorder (VCR) Playback
UHF (TV)
1. Connect your UHF aerial downlead to the RF input socket of the VCR.

2. Connect the aerial flylead from the VCR (usually connected directly to the TV) to the ANT input of the SLx1. 3. Connect the aerial flylead from the TV output of the SLx1 to the aerial input on your TV.

METHOD 3 Satellite Receiver Signal Distribution If you wish to distribute signals from a satellite receiver: 1. Connect your UHF aerial downlead into the satellite receiver’s UHF aerial input. 2. Connect the VCR output flylead from the satellite receiver to the ANT input of the SLx1. Signals from the receiver can now be watched on your TV. 3. Alternatively connect the satellite receiver output into your VCR.
4. Connect your VCR output as per METHOD 1. UHF TV, VCR playback and satellite receiver signals will now be available to your 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.
The SLx1 Aerial Amplifier has an adjustable gain control to alter the picture signal quality.
Troubleshooting If you are still experiencing reception problems after the installation of your SLx1 Aerial Amplifier, please refer below.
Analogue Terrestrial TV 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. In a small number of cases, a snowy picture can also be caused by a TV signal that is too strong. ‘Herringbone’ Pattern ‘Herringboning’ is generally caused by too strong TV signal or possibly 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.
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. 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. When interconnecting equipment and to get the best carrier to noise then place the digital terrestrial television set top box as the first item in the signal path followed by any video or satellite receiver. 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. For specific help with DTT reception problems, log onto www.dtg.org.uk.
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.
Intermittent Connections Make sure all RF cable to connector joints are tight (both inner and outer) including all flyleads and outlet plate connections.
