USER GUIDE

SLx low noise, high gain aerial ampliers

27828 27828SP 27828HS 27828R

We have integrated the very latest in digital-ready signal amplication 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.

The SLx range of Aerial Ampliers 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.

With full instructions, wall mounting bracket and template, installing and operating an SLx Aerial Amplier is both quick and easy.

METHOD 2

Video Cassette Recorder (VCR) Playback

1. Connect your UHF

aerial downlead to the RF input socket of the VCR.

2. Connect the aerial ylead from the VCR (usually connected directly to the TV) to the ANT input of the SLx1.

3. Connect the aerial ylead 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 ylead 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 Amplier has an adjustable gain control to alter the picture signal quality.

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 amplier. 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 insufcient 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 rst 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 reections. They remain perfectly

receivable under conditions where an analogue

signal would suffer ghosting.

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 yleads

and outlet plate connections.
