INSTALLATION INSTRUCTIONS
This range of six amplifiers is ideal for use in small domestic and commercial reception and distribution
s stems. The proAMP24, proAMP26 and proAMP28 are traditional 4-, 6- and 8-wa aerial signal
amplifiers. The R versions have a 6 MHz return path, for use with infra-red remote control extender
s stems of the t pe which connect to the RF OUT-2 output of a Sk * Digibox.

Fi ings
Fix the amplifier to a sound vertical surface such as a wall or equipment mounting board. Ventilation
gaps of at least 30 mm should be left around the front and all sides of the unit. More clearance will be
required below and to the right of the unit to allow access for the signal cables.
Do not leave the amplifier resting on a carpet or install it where it may become smothered
with curtains or other soft furnishing fabrics. When installing the amplifier in a roof space
ensure that it will not come into contact with thermal insulation material.
Signal connections
To preserve RF screening integrit the signal connections to the amplifier should be made using good
qualit coaxial cable and connectors. This is particularl important with digital terrestrial TV (DTT) to
minimise the ingress of impulsive electrical interference from home appliances.
nThe use of cable benchmarked under the CAI scheme is recommended.
nAmplifiers proAMP24, proAMP26 and proAMP28 require IEC connectors (IEC 60169-2).
nAmplifiers proAMP24R, proAMP26R and proAMP28R require T pe-F connectors (IEC 60169-24).
For both connector t pes the use of crimp connectors, used in accordance with the manufacturers
instructions will give the best results. The importance of achieving sound braid connections cannot be
over-stressed.
Important: the FULL output (where fitted) must alwa s be terminated in a well-matched 75 Ω load.
The terminator plug supplied must be fitted if this output is not used. (See also the section headed
Usin the FULL output.)

Safety Instructions
OVERHEATING
The recommended ventilation clearances and other precautions given in the relevant section
of this instruction leaflet should be observed to prevent overheating. No unit should be
fixed where it is likel to become smothered b soft furnishing fabrics such as curtains, or b
thermal insulation material in a roof space or building void. Mains powered equipment
should not be left resting on a carpet.
WATER AND FIRE RISKS
The appliance is not waterproof. It is intended for indoor use onl and must not be fixed
where it could be exposed to dripping or splashing water. Objects containing liquids should
not be placed on or near the appliance.
To prevent risk of fire, no object with a naked flame should be placed on or near the appliance,
or its associated wiring.
MAINS PLUG
The appliance is supplied with a standard fused plug fitted. If this is unsuitable, refer to the
instructions below. If ou need to change the fuse in the fitted plug, a 3 Amp fuse to BS
1362 carr ing the ASTA or BSI approval mark must be used. Alwa s replace the plastic fuse
carrier when renewing the fuse.
CHANGING THE PLUG
If the fitted mains plug is not suitable for the socket-outlets in use, it should be cut off and
a new plug fitted.
Wiring the New Plug: Instructions supplied with the new plug should be followed. The
brown wire must be connected to the live (L) terminal of the plug and the blue wire to the
neutral (N) terminal. Neither wire should be connected to the earth (E) terminal of a 3-pin
plug (the appliance does not require an earth connection). Ensure that the cord grip in the
plug is correctl used and clamps the sheath of the cord firml .
Fuse Rating: If the new plug is a fused t pe, the fuse fitted should be rated at not more than
3 Amp.
Caution: The old plug should be destro ed immediatel since it would be dangerous if
plugged into a live socket.

Technical data
Using remote control
R versions of the amplifiers are compatible with the PROception proSAT1E E and other Sky* remote
control extenders. To use the remote control feature it is essential that the amplifiers 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 SUPPL 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.
