Technical data
Using remote control
R versions of the amplifiers are compatible with the
PRO
ception proSAT1EYE and other Sky* remote
control extenders. When using remote control 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 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 3s 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
PRO
ception 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 amplifier provide filtering outside and between these bands. Where more
than one aerial is to be connected a separate diplexer such as the
PRO
ception proCOM31T should be
used (see example 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 amplifier (otherwise the other 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.
proOUT12C
FM aerial
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 (VHF
FM and DAB radio signals should not exceed -10 dB relative to analogue TV).
