Applications
These amplifiers are designed to boost and distribute signals from the RF2 output of a satellite
receiver and or terrestrial TV and radio aerial signals. When using these amplifiers with a Sky
Digibox, the amplifier must be fed from the RF OUT-2 socket of the Digibox. However if the RF2
Channel is set to 59 or above (68 is usually the default channel) you will need to reset it to a
channel from 21-58 in the Digibox Setup Menu.
To view satellite RF2 output TVs require an analogue tuner.
Later Digibox models such as the Sky+HD 2TB are not fitted with an RF OUT2 output and you will
need an I/O converter such as the Labgear MRX600K to distribute signals from the Digibox to
other TVs.
The LDL distribution amplifiers are suitable for digital TV signal distribution for Ch21-60. If you are
affected by 4G interference in your area you may need a Ch60 filter (currently available from
at800 free of charge).
Resetting the RF Channel on a Digibox
1. Switch on your Sky™/Sky+™/ Sky+ HD™ receiver and view on your main television.
2. Press the SERVICES button on your Sky™ remote.
3. Select SYSTEM SETUP option (for SKY+ HD there is no SYSTEM SETUP option press 0 instead).
4. Press the following buttons in sequence: 0, 1, SELECT (for SKY+ HD this is a hidden
option and does not appear on screen). You should now see the installers’ menu.
5. Select the RF channel number option and key in a new channnel number from 21-58 and
select ‘Power On’. Make a note of the channel number you choose as you may need it when
tuning your other TVs.
Installation
Important note:
please read the General Safety Precautions before installing this amplifier.
Location
Try to choose a location for the amplifier which is convenient for cable runs to the system outlets
but which is not too far from the aerial. Select a cool, dry, well ventilated area which is free of
any risk of dripping or splashing water. Stand on a stable flat surface (not a carpet or insulating
material) or fix to a wall or sturdy upright (screws not provided). Do not allow the amp to hang
on the cables.
Ensure that there is adequate space to ensure cables are not kinked when connecting (mini-
mum 120mm radius recommended) and that above and on the free sides of the amp there is
at least 25mm for ventilation. Do not cover.
Electricity supply
Each unit is supplied with a fitted mains plug with 3A fuse, if this is not suitable get a competent
professional (ELECSA or NICEIC) to make the connection with an isolating switch to allow it to be
disconnected when necessary.
