This versale product is an addion to the PROcepon range of mul-way distribuon ampliers. The
unit has two modes of operaon, allowing it to be used either as a straighorward 10-way aerial
amplier for o-air signal distribuon, or as a return-path amplier with its UHF input fed from the loop
through output (RF OUT-2) of a Sky* satellite receiver or similar device. In its return-path mode full
support is provided for remote infrared receivers (eyes). The use of F connectors makes the amplier
easy to install and helps to ensure good system screening.
All these ampliers are compliant with the Radio Equipment Direcve 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 mulple 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:
• Separate ltered inputs for the FM radio, DAB (Band III) and UHF TV frequency bands.
• Ten independent outputs.
• Dual-mode operaon: standard signal distribuon amplier; or return-path amplier.
• Flexible powering opons: local or remote power supply locaon.
• Automac mode selecon with 2-colour LED mode and power indicator:
 Green - Mode 1, Orange - Mode 2, Red - Power.
• Bandpass lters on VHF inputs. UHF input ltered below 470 MHz to reduce risk of interference
from CB, private mobile radio, TETRA, etc.
• Line-power for preamplier available at UHF input.
• Suitable for both digital and analogue applicaons, fully DDT-compable.
• Channels 61-68 can be used for locally modulated signals.
Mode 1 aerial amplier mode (green LED): in this mode the unit funcons as a straighorward mul-
way amplier for distribuon of o-air and/or locally generated RF signals around a building. The input
signals will usually come directly from the corresponding aerials. Line-power (5V) for a masthead or
similar preamplier is available at the UHF input in this mode.
Powering Opons
Line-power for this amplier (12—15V DC) can be supplied via any of the ten outputs. Alternavely, if a
mains supply is available near the amplier, a suitable 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 amplier and remote control
funcons are completely disabled.
Note (Mode 1): this amplier is not suitable for powering from the aerial sockets of DVB-T (DTT or Freeview†)
receivers. The voltage and current available from such receivers (usually 5V at 30mA) are insucient.
Fig.1(a) shows a typical Mode 1 applicaon with power provided by a PROPSU112X power unit
connected in one of the output lines.
Fig.1(b) shows a similar installaon to Fig.1(a), except that a PROMHD11L masthead preamplier is
used to boost the UHF input signals and power is provided by an AC/DC power adaptor adjacent to the
amplier. This diagram also shows how one or more of the output lines can be split to provide
addional outlet points.

Preamplier Power Opon
Line-power for a masthead or similar preamplier is available at the UHF input in Mode 1. The
amplier provides approximately 5V with a current rang of 30mA max., suitable for powering a
PROcepon PROMHD11L or PROMHD11M preamplier. If using other ampliers, take care to
ensure that the current rang is not exceeded. Use a preamplier only when the UHF input signals
would otherwise be too low in level—i.e. where the signal levels from the aerial are low, or where
there is an unusually long cable run between the aerial and the PROAMP310X amplier. Always use
the minimum amount of preamplier gain necessary to obtain sasfactory signal levels at the
amplier input.
Preamplier power is normally present at the UHF input, but will shut down if the aerial presents a
short-circuit at the input. Note that this shut-down is not self-reseng. If preamplier power is
wanted, but has been shut-down by a temporary short circuit, it must be reset manually by
removing power to the amplier for a few seconds. If necessary, preamplier power can be
permanently disabled by means of an internal jumper (see “Advanced conguraon features” on
page 7).
Addional UHF sources
Any addional UHF signal sources such as CCTV camera channels should be combined with the
aerial signal feed ahead of the PROAMP310X. This is done best using equipment providing a
buered loop-through arrangement (e.g. the PROcepon PROMOD1 video and audio modulator) or
by the use of suitable combining lters. The pracce of using wideband combiners is discouraged
since it can degrade signal-to-noise raos and can cause locally generated signals to be radiated
from the aerial, possibly causing interference to other viewers.
Note: where auxiliary equipment connected to the UHF input might be aected or jumper facility menoned in
the previous secon.

Notes
1. UHF signal handling capability is given for 5 analogue TV channels plus up to 6 DTT
multiplexes at ≤ -14 dB relative level.
2. The first (higher) figure is for analogue signals and the second (lower) is for digital (16– or
64-QAM).
3. Rejection figures are given relative to the nominal passband gain.
4. Absolute minimum voltage, measured to the bottom of the ripple present.
5. Highest recommended mean voltage for operation over the full temperature range.
6. Eye load should be restricted to 80 mA or less when using PROPSU112X power unit (see
text).
7. Both UHF preamp and IR eye power outputs have fold-back short-circuit protection, but not
overload protection. It is the installer’s responsibility to ensure that the stated current
ratings are not exceeded.
Certain features of this amplifier are the subject of UK patent application GB 2425443.

Technical Data proAMP310X
Fig.2(a) - example Mode 2 applicaon with remote power unit.
Mode 2 return-path mode (orange LED): this mode is applicable when using RF OUT-2 of a Sky
satellite receiver, PVR or a similar device. This will then allow remote infrared receiver eyes (such as
the PROcepon PROSAT1EYE Mk 2) to communicate with the Sky box, so that the Sky receiver can
be controlled from a remote viewing locaon.
Powering
Mode 2 is automacally enabled when the amplier detects the presence of 9V (or higher) DC at its
UHF input (see the following secon for further details). In this mode the LED indictor changes from
green to orange and a voltage (approx. 9 V DC) is present at each output for powering a remote
infrared receiver.
Infrared receiver power is individually short-circuit protected, so that a DC short at any output will
not aect operaon of remote control via other outputs.
Fig.2(a) shows a typical Mode 2 applicaon with power provided by a PROPSU112X power unit
connected in the UHF return feed from the Sky receiver.
Fig.2(b) shows a similar installaon to Fig.2(a), except that power is provided by an AC/DC mains
power adaptor adjacent to the amplier.
Magic Infra-Red Eye Count
When using the remote powering opon with the PROPSU112X the total number of infrared ‘eyes’
on the system may need to be restricted. The PROPSU112X is rated to supply a maximum of 200mA
and approximately 120mA is drawn by the amplier itself. Thus the total ‘eye load’ is limited to
80mA. This means that a maximum of eight ‘industry-standard eyes’ (each consuming about 10mA)
may be connected to the amplier outputs. This restricon is removed if the PROcepon
PROSAT1EYE Mk 2 eye is used, since this consumes less than 5mA. Up to 10 eyes may be connected
without restricon when using the PROPSA125 AC/DC mains power adaptor.
Fig.2(a) - example Mode 2 applicaon with remote power unit.

General Instrucons for both Mode 1 & 2
Signal Connecons
To preserve RF screening integrity, the signal connecons to the amplier should be made using
good quality coaxial cable and connectors. This is parcularly 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 manufacturer’s instrucons, will give the best
results. The importance of achieving the sound braid connecons cannot be over-stressed.
Connectors should be ghtened with a spanner, not le nger-ght. Unused inputs and outputs of
this amplier do not need to be terminated.
Power Supplies
• PROPSU112X - 12V power unit connected anywhere in the UHF return feed (i.e. in the line
between RF OUT-2 of the Sky receiver and the amplier’s UHF input) Fig.2(a);
• PROPSA125 - a local AC/DC mains power adaptor connected to the DC power port, as in Fig.2
(b). The adaptor doesn't need to be regulated but does needs to have a standard 2.1mm DC
connector with the correct polarity (centre pin +ve). If a 3rd party adaptor is to be used its
output should conform to the requirements given in the technical data secon (page 8).
When using this opon the UHF input must be directly connected to the Sky receiver RF OUT-
2, since the 9V second outlet power needs to be sensed at the UHF input to switch the
amplier to Mode 2. The current drawn from the Sky receiver in this conguraon is very
small (typically 3-5mA).
Mains Power Supply
Any xed wiring installed to supply power for this amplier should comply with BS7671 (IEE wiring
regulaons) and, where relevant, Part P of the building regulaons. Refer to the instrucons
provided with the power supply unit for other safety informaon.
Spling outputs
As with any mul-way amplier the output signals can be split as illustrated in Fig1(b) to provide
addional outlet points. The PROcepon PROSPL204 splier is suitable for this in Mode 1 and
introduces approximately 4dB inseron loss. Spling outputs in Mode 2 is not recommended,
since it is not possible to provide individually protected eye power to the split outputs.
Signal levels
This amplier has relavely low forward gain gures and assumes that adequate input signal levels
will be available from properly installed aerials. The amplier gains are sucient to compensate
for addional distribuon cable losses in a typical domesc-scale systems whilst avoiding the
intermodulaon and other overload problems which result from the use of excessive gain.
Recommended minimum and maximum signal levels for each of the frequency bands are given in
the Technical data secon on page 8. Parcular aenon should be paid to the input VHF radio
signal levels. In city areas, very strong signals are oen received and it may be necessary to use
aenuators on one or both of the VHF inputs to avoid overloading the amplier.
Outlet plates
The use of outlet plates is recommended to provide a professional standard of nish to the
distribuon system. PROcepon’s screened outlet plates are recommended for use with this
amplier. The diplexed TV and radio plate (PROOUT12C) allows both TV and radio equipment to
be connected simultaneously to an outlet point. Single outlets (PROOUT11C) may also used and
will allow either TV or radio equipment to be used. The system diagrams in Fig.1&2 show both
types of plate in use.
In Mode 2, a PROOUT11C plate may also be used to provide the UHF return input connecon from
the Sky receiver, as illustrated in the diagrams in Fig.2.
Installaon locaon and xing
Choose a locaon for the amplier which is dry and not subject to prolonged ambient temperature
condions of less than -10°C of more than +40°C. Fix the unit to a sound vercal surface such as a wall
or equipment mounng board. Venlaon gaps of at least 50mm should be le around the front and
all sides of the unit. More clearance will be required around sides where cables are connected.
Do not install the amplier or its associated power unit where they may become smothered with
curtains or other so furnishing fabrics. When installing the amplier and power unit in a roof space,
ensure that they will not come into contact with thermal insulaon material.
System Equipotenal Bonding
A bonding terminal is provided on the amplier for use where necessary. Distribuon systems
supplying signals to more than one household should comply with he safety requirements of BS EN
60728-11. This eecvely requires earthed equipotenal bonding of the system. The use of isolated
outlet plates is no longer recommended since they compromise screening integrity and allow ingress of
interference.
Advanced Conguraon Features
Note: access to the features described in this secon involves opening the unit. The procedures below should only be carried out by a
competent person, preferably under workshop condions.
• UHF input line-power (preamplier power): where equipment (such as an aenuator) connected
to the UHF input might be damaged by the presence of the 5V output, or may cause the 30mA
current rang to be exceeded, the input line-power can be permanently disabled by removing the
internal LINE-POWER jumper.
• Forced Mode 2 operaon: where Mode 2 operaon is desire, but it is impraccable to connect a
Sky receiver directly to the UHF input to provide a 9V sense voltage. The unit can be forced into
Mode 2 by placing a jumper link on the 2-pin header labelled FORCE MODE 2. Since UHF input line
-power will not usually be required in Mode 2, the exisng LINE-POWER jumper can simply be
moved to the FORCE MODE 2 header posion. Forced Mode 2 operaon is only relevant when a
local power unit is in use, connected to the DC power port.
• Access: to open the unit remove the four corner screws from the rear cover. Separate the two
halves of the moulded cover and withdraw the screened amplier assembly, together with the
aached DC port connector. Remove the top metal lid (this is the side with the LED). One side of
the PCB is now exposed. Take great care not to disturb any of the coils, as this could de-tune the
input lters. The LINE-POWER jumper is located just above the LED; the Force MODE 2 jumper is
in the boom right-hand corner of the board, near the equipotenal bonding terminal.
• Re-assembly: when reassembling the unit, take care to ensure that the LED does not become
trapped and pushed inside the unit, and that the DC port connector is correctly seated in the
cover mouldings before replacing the screws.
Set-Up
The Sky receiver should be congured 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
opon. Set this to be ON (the default state is OFF), SAVE SETTINGS and BACK UP out of the menu.
Interlock funcon: if a connector is present in the amplier's local DC power port then power will not
be accepted via the UHF input, regardless of whether the AC/DC mains power adaptor is actually
providing power. This is an interlock funcon which prevents the Sky receiver trying to power the
enre distribuon system in the event of failure of, or loss or power to, the local power adaptor.
Important note: this amplier is not suitable for powering directly from a Sky receiver. The
conguraon where the Sky receiver's RF OUT-2 is directly connected to the amplier's UHF input
without a local mains power adaptor present is not permied.
