PROAMP104X www.blake-uk.com/104x
Dual-mode 4-way UHF amplier Instrucon Manual
The versale amplier is an addion to the PROcepon range of UHF mul-way distribuon ampliers.
The unit has two modes of operaon, allowing it to be used either as a straight forward mul-way
aerial amplier for o-air signal distribuon, or as a return path amplier for distribuon of the UHF
loop-through output of a Sky* receiver. In the laer mode full support is provided for remote infrared
receivers ( eyes ). The use of F connectors makes the amplier easy to use and helps to ensure good
system screening.
All these ampliers are compliant with the Radio Equipment Direcve 2014/53/EU and meet the
harmonised standard EN 303 354 for Class 0. As such they work on ALL current UK DTT channels
including channel 60, are resilient to interference and overloading, and cope with mulple carriers. In
cases of strong LTE interference a separate 4G lter should be ed. These are supplied free by at800,
or higher performance models can be purchased from www.blake-uk.com. (To pass channels up to
and including channel 59 use proLTE1/59, or if channels 58 and 59 are not required, use proLTE1/57).
Features:
• Dual-mode operaon: can operate as an aerial amplier, or as a return-path amplier with Sky*
remote control facilies.
• Flexible powering opons: 5 - 15 V (local or remote) for aerial-amplier mode; 9 V from Sky*
receiver for return-path mode.
• Automac mode selecon. 2-colour LED indicates operang mode.
• Excellent low noise gure and output capability.
• Input ltered below 470 MHz to reduce risk of interference problems from CB, private mobile
radio, TETRA, etc.
• Suitable for both digital and analogue applicaons, fully DTT-compable.
• Channels 61-68 can be used for locally modulated signals.
Applicaon guide:
See applicaon example diagrams on page 2.
Mode 1 aerial amplier mode (green LED): in this mode the unit funcons as a straighorward 4-way
UHF amplier. The input will usually come directly from the UHF antenna. Line-power (5 - 15 V DC) can
be supplied via any of the four outputs. Alternavely, if a mains supply is available near the amplier, a
local AC/DC mains power adaptor may be used instead of line-powering. In Mode 1 no power is passed
to unpowered outputs and the return-path amplier funcon is completely disabled.
Mode 2 return-path mode (orange LED): this mode is automacally enabled when the amplier is
powered via its input. Usually the input will be fed directly from the second RF output (RF OUT-2) of a
Sky Digibox or Sky+* receiver or a Sky Digibox with an I/O port# , which should have its 9 V powering
enabled (see over). In return-path mode power is present at all outputs for powering remote infrared
receiver eyes, such as the PROcepon proSAT1EYE. Infrared receiver power is individually short-circuit
protected, so that a DC short at any output will not aect operaon of remote control via the other
outputs.
The relavely low forward gain of the amplier (4 dB) is sucient to compensate for addional
downlead cable losses in most systems, whilst avoiding intermodulaon and other overload problems
which easily result from the use of excessive gain. Where more gain is needed in aerial-amplier mode
(for example in installaons with very long cable runs, or in weak signal areas) the proMHD14M or
proMHD14V 4-way masthead ampliers should be considered instead (these alternave products do
not provide return-path capability).

Powering opons:
Power for operaon in Mode 1 can be supplied by any of the following three opons:
1. A PROcepon PROPSU11F or PROPSU12F 12 V power unit connected in any of the output lines (Fig 1);
2. A local AC/DC power adaptor capable of providing 5 - 15 V at 25 mA (such as the PROcepon
PROPSA125) connected to the DC power port (Fig. 1). The adaptor need not be regulated and needs
to have a standard 2.1 mm DC connector with the correct polarity (centre pin +ve);
3. A DVB-T (FreeView) receiver of a type which can provide 5 V DC power from its antenna socket. A
separate power unit will not be required if this type of receiver is in use on any of the outputs,
provided that it can be le connected connuously to the mains supply.
In Mode 2 9V power is provided to the input of the PROAMP104X by the Sky* receiver (Fig. 2). The laer
must be congured in its INSTALLER SET-UP menu to provide power on RF OUT-2. On the Sky handset
press SERVICES, 4, 0, 1, SELECT, then select the SECOND OUTLET POWER SUPPLY opon. Set this to be ON
(the default state is OFF), SAVE SETTINGS and BACK UP out of the menu. Most Sky* receivers (rated at 75
mA on RF OUT-2) can supply sucient current to power the PROAMP104X together with up to four
industry-standard infrared eye receivers. For older Sky* receivers with only 50 mA current rang the
current consumpon can be reduced suciently by adopng one of the following two measures:
1. Use only PROcepon proSAT1EYE Mk. 2 eyes. The Mk. 2 version of this product (disnguished by its
hard-wired RF output lead) has a reduced current consumpon of <5 mA;
2. Alternavely connect a local AC/DC power adaptor capable of providing 12 - 15 V at 25 mA such as
the PROcepon PROPSA125 to the DC power port. The adaptor need not be regulated and needs to
have a standard 2.1 mm DC connector with the correct polarity (centre pin +ve). This power unit will
power the forward-path amplier funcon and will reduce the loading on the Sky* receiver by
approximately 25 mA.

Fixing:
Fix the amplier to a sound vercal surface such as a wall, skirng board or equipment mounng
board. Venlaon gaps of at least 50 mm should be le around the front and sides of the unit. More
clearance will be required below the unit to allow access for the signal cables.
Being fully screened, the amplier will not be aected by proximity to an antenna. However clearance
of not less than 300 mm from the nearest part of the antenna should be observed to avoid degrading
the antenna's performance. Manufacturer's instrucons regarding roung of the cable from the
antenna terminal box must be followed if provided.
Do not leave the amplier resng on a carpet or install it where it may become smothered with
curtains or other so furnishing fabrics. When installing the amplier unit in a roof space ensure that
it will not come into contact with thermal insulaon material.
Signal connecons:
To preserve RF screening integrity the signal connecons to the amplier should be made using good
quality coaxial cable and connectors. This is parcularly important with DTT to minimise the ingress of
impulsive electrical interference. The use of cable benchmarked under the CAI scheme is
recommended.
Crimp F connectors, used in accordance with the manufacturers instrucons, will give the best
results. The importance of achieving sound braid connecons cannot be over stressed.
System earth bonding:
Earth bonding terminals are provided on the amplier casngs for use where necessary (see Fig. 3).
Distribuon systems supplying signals to more than one household should comply with the safety
requirements of EN 60728-11 . This eecvely 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.)
