Fi ings
Fix the amplifier to a sound vertical surface such as a wall or equipment mounting board Ventilation
gaps of at least 50 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 integrity the signal connections to the amplifier should be made using good
quality coaxial cable and connectors This is particularly 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, 26 and 28 Mk 3 require IEC connectors (IEC 61169-2)
nAmplifiers proAMP24R, 26R and 28R Mk 3 require Type-F connectors (IEC 61169-24)
For both connector types 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 F connectors should be tightened with a spanner, not left finger tight
Important: the FULL output (where fitted) must always be terminated in a well-matched 75 Ω load
The terminator plug supplied must be fitted if this output is not used

Safety Instructions
OVERHEATING
These amplifiers are intended for use in moderate climates only They should not be used in
tropical regions 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 likely to become smothered by soft furnishing fabrics such as curtains,
or by 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 only 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 AND DISCONNECTION FROM THE SUPPLY
The appliance is supplied with a standard fused plug fitted If this is unsuitable, refer to the
instructions below If you need to change the fuse in the fitted plug, a 3 Amp fuse to BS 1362
carrying the ASTA or BSI approval mark must be used Always replace the plastic fuse carrier
when renewing the fuse The plug (or other means of disconnection from the supply, if used)
should remain readily accessible for operation when necessary The LED power indicator on
this equipment should not be regarded as providing reliable indication of supply disconnection
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 line (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 correctly
used and clamps the sheath of the cord firmly
Fuse Rating: If the new plug is a fused type, the fuse fitted should be rated at not more than
3 Amp
Caution: The old plug should be destroyed immediately 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 proSAT1EYE and other Sky remote
control extenders. When using remote control 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 SUPPLY option. Set this to be ON, SAVE SETTINGS
and BACK UP out of the menus.
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 approximately 9 V 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 readily accessible 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. A readily accessible 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) and, where relevant, Part P of the building regulations. 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.
System equipotential bonding
Distribution systems supplying signals to more than one household should comply with the safety
requirements of BS EN 60728-11. This effectively requires earthed equipotential bonding of the system.
(Isolated outlet plates cannot be used with proAMP R versions for functional reasons.) Although not
mandatory in single households, system equipotential bonding is strongly recommended for all
installations. All proAMP Mk 3s are provided with a bonding terminal. A bonding conductor of 4mm²
should be provided, connected to the main earth terminal of the electrical installation which supplies
the unit. Bonding may be effected using PROception proBAR5 or 8 equipotential bonding bars.

Dual-band VHF input
The VHF input will accept Band II FM radio signals and/or DAB or TV signals in Band III. Separate
bandpass circuits in the a plifier provide filtering outside and between these bands. Where ore
than one aerial is to be connected a separate diplexer such as the PROception proCOM31T should be
used (see exa ple in Fig.1).
Making use of the FULL output
The FULL output (where fitted) allows additional outlets to be fed via an external passive network. This
network should present a good 75 Ω load to the a plifier (otherwise the other outputs will be affected).
Fig. 1 shows an exa ple of correct practice, using an 8-way tap unit to provide eight additional outlets.
The ter inator plug supplied ust always be fitted if the FULL output is not used.
