Technical data
Using remote control
R versions of the amplifiers are compatible with the
PRO
ception proSAT1EYE and other Sky* remote
control extenders. To use the remote control feature it is essential that the amplifiers UHF input is
fed directly from the RF OUT-2 connector of the Sky receiver. The amplifier provides 9 V DC power
for remote eyes on all outputs. Note that some Sky receivers require their RF OUT-2 power option
to be enabled in order for remote control extension to work. On the Sky handset press SERVICES, 4,
0, 1, SELECT, then select the SECOND OUTLET POWER SUPPLY option. Set this to be ON, SAVE
SETTINGS and BACK UP out of the menu.
As always with wired remote extender systems, it is essential to maintain DC continuity through the
coaxial cabling between the amplifier output(s) and the IR receiver equipment in the remote room(s).
For this reason isolated outlet plates cannot be used in the remote rooms and all connections must be
securely clamped, crimped or soldered. When troubleshooting remote control problems, the first step
should be to check for the presence of approx. 9V DC on the cable in the remote room.
Mains supply connection and safety notes
The amplifier is supplied with a fitted mains plug and may be plugged directly into a 13 A (BS 1363)
socket outlet. If socket outlets of a different type are in use, please refer to the safety instructions on
page 4. Alternatively the plug may be cut off and the amplifier wired into a fused connection unit,
fitted with an approved 3 A fuse to BS 1362. This method of connection is recommended for permanent
distribution system applications, since it reduces the risk of tampering and accidental disconnection.
If the amplifier is
not
connected to the mains using the fused plug supplied, or a fused connection
unit, it must be protected by means of a fuse or MCB at the final distribution board of rating not
exceeding 6 A. An isolating switch should be provided to allow the unit to be disconnected from the
supply when necessary.
Any fixed wiring installed to supply power to this amplifier should comply with BS 7671 (IEE wiring
regulations, 16th Edition).
proAMP amplifiers are of Class 2 construction and do not require a protective earth connection. This
does not obviate the need to provide a circuit protective (earth) conductor in the supply wiring, as
required by BS 7671.
Distribution systems supplying signals to more than one household should comply with the safety
requirements of BS EN 50083-1. This effectively requires the system to be earth bonded. (The use of
isolated outlet plates is no longer recommended since they compromise screening integrity and allow
ingress of interference.)

Making use of the FULL output
The FULL output (where fitted) allows additional outlet points to be fed using only a simple external
passive network. The passive network should always present a good 75
Ω
load to the amplifier
(otherwise the other amplifier outputs will be affected). Fig. 1 shows an example of correct practice,
using an 8-way tap unit to provide eight additional outlets. The terminator plug supplied must always
be fitted if the FULL output is not used.

Notes:
1. Full output is not fitted on R versions.
2. Output capability is given for 5 analogue TV channels plus up to 6 DTT multiplexes at
£
-14 dB relative level (FM
radio signals should not exceed -10 dB relative to analogue TV).
