(See instructions on how to use these products with the New Sky Boxes Here)



Recently introduced Sky set-top receivers and PVRs such as the DRX595 and DRX890 series no longer provide a UHF modulated output. A consequence of this is that they have no ‘RF‑2’ connection for distribution to other rooms of a house.


A significant difference between the iO‑LINK and ‘RF‑2’ is the available current for powering remote infrared ‘eyes’ and associated amplifiers. The iO‑LINK will only power one eye, whereas ‘RF‑2’ on the older receivers could power a typical 4-way distribution system (75 mA max).


The iO‑LINK (‘tvLINK RF out Replicator’) is a Global Invacom product which plugs into the accessory I/O PORT of the new Sky set-top box and provides a modulated PAL output together with the remote control facilities formerly provided by RF OUT-2. An aerial loop-through facility is also provided.


Use PROception products with iO‑LINK to build multi-way systems...

It's easy to use the iO-LINK with the unrivalled PROception range of amplifiers and accessories to build multi-room systems, allowing users to watch and control their Sky receiver from every TV room in the house.

For a simple single extension room only a proSAT1EYE infrared ‘eye’ is required. Larger systems will need a suitable amplifier to distribute the signals and power the eyes. The recommended product configurations below have all been tested for compatibility with iO-LINK.


PROception Alternative to iO-LINK (PROLINK22)

Flexible RF Output Modulator, restoring traditional Sky distribution

Distributing the analogue RF output of a Sky box from the main TV location to other rooms remains a popular solution for aerial installers. The new PROception proLINK22 modulator and remote control unit allows unrivalled flexibility for this application.


• Replaces the 'missing' RF outputs on newer Sky receivers.

•High-quality UHF modulator with infrared return remote control capability on BOTH of its twin F-type RF outputs.

• Simple channel setting using Sky box menu.

• Two remote rooms can be wired directly from the proLINK (expandable to three using a splitter and without a power supply)*

• Connect optional power unit (proPSA123 or proPSA125) to power 4-way system using proMHD14R or proAMP104X amplifier. 10-way system also possible using proAMP310X.

• 2-colour power-status indicator.

• Wall mountable with extended lead. (500mm)


*This requires the use of PROception proSAT1EYE IR eyes and assumes that the local TV is connected by Scart or HDMI and does not require an RF antenna connection. Recommended splitter is proSPL204 (See more information here)



Another PROception Alternative to iO-LINK (PROMOD32) 

Versatile UHF Modulator - Compatible with the new for Sky I/O STB, Freesat, Freeview, PVR & DVDs

The new proMOD32 fills the gap left by the removal of RF modulators from many digital set-top boxes, recorders and similar products. This unit allows continued use of the popular 'extension room' application, where the selected programme output of a settop device is distributed to a number of room outlets, with full remote control capability.



• Home control of a master Set-top box (Sky, Cable* or Freesat*), PVR* or DVD*.

• Control and Watch these different devices on other TVs around the home.

• High quality UHF sound and vision modulator (UK PAL RF output with mono audio)

• Supports the new Sky I/O port interface for simple single-lead connection to newer Sky boxes. Replaces Sky's ‘RF-2’ facility, including remote control. 

• Provides DC power for optional 4-way remote amplifier and up to four IR 'eyes'.

• RF return path for remote control extension to Sky receiver and IR blaster.

• RF loop-through connection with LTE-protected input & tamper-resistant output channel setting.


• RF tuning signal provided after power-up or output channel change for easier installation.


*STB, DVDs & PVR that include SCART outputs. Note a Sky I/O connection and a SCART can be connected at the same time but will modulate the last product powered. (See more information here)





System Components for iO-Link Compatibility with Other Equipment:


Infrared Eye (PROSAT1EYE Mk 3)


• Installers' favourite.

• Compatible with iO-LINK.

• Low current consumption (5 mA) eases loading on amplifiers etc.

• Wide working voltage range.

Note: no additional amplifier or PSU is required if feeding only one remote room.



 Mains powered amplifiers
(PROAMP-R series)


Mains powered amplifiers with integral PSU

Max. ways Amplifier PSU VHF
2 PROAMP12R  - No
4 PROAMP24R - Yes
6 PROAMP26R - Yes
8 PROAMP28R - Yes


• Traditional ‘return-path’ amps

• Compatible with iO-LINK

• Two, four, six or eight output ways

Note: the 4-, 6- and 8-way amplifiers have a separate VHF input covering bands II (FM) and III (DAB) with dual bandpass filtering. Any VHF feed must be connected to this input, not routed via the iO-LINK.



Starboxes (PROSTR range)



starBOX Products – mains powered with integral PSU

 Max. Ways   starBOX  PSU   VHF 
5 PROSTR5S - Yes
10 PROSTR10S - Yes



• Combines LNB & terrestrial feeds to a master outlet plate

• UHF ‘return’ and VHF inputs distributed to 5 or 10 room outputs

• Compatible with iO-LINK

Note: see product literature and instructions for the full capabilities of these products. Connect feed from the iO-LINK to the UHF return input and any VHF feeds to the relevant amplifier inputs.



‘New generation’ 4-way amps



Flexible line-powered amplifiers (4-way)

 Max. Ways  Amplifier  PSU   VHF 


PROAMP104X - Compact 4-Way amplifier for indoor use only.

PROMHD14R - Mashead style amplifier. (indoor or outdoor)



• Versatile dual-mode amplifiers

• Flexible powering options

• Compatible with iO-LINK when used with recommended PSU (see table)


Note: The PSU can be located anywhere in-line between the iO-LINK and the amplifier. iO-LINK output is connected to OUT on the PSU and IN (+12V) on the PSU goes to the input of the amplifier. Do not attempt to power proAMP104X with local DC power unit, e.g. proPSA123, for this application.

* PSU must be the Mk 2 version. The amplifiers operate in Mode 2 (orange indication for proAMP104X).

 Max. Ways   Amplifier   PSU   UHF 
10  PROAMP310X 






• Versatile dual-mode amplifier

• Flexible powering options

• Compatible with iO-LINK when used with recommended PSU (see table)


Power option (1) – Local powering with proPSA123

Connect iO-LINK output directly to UHF input of amplifier and any VHF feeds to the relevant amplifier inputs.

Power option (2) – Line powering with proPSU112X.

PSU can be located anywhere in-line between the iO-LINK and the amplifier. iO-LINK output is connected to IN/OUT on the PSU and AMP (+12V) on the PSU goes to the UHF input of the amplifier.


Connect any VHF feeds to the relevant amplifier input. The amplifier operates in Mode 2 and should display the orange indication.




Using passive splitters

A 2-way passive splitter such as the proSPL204 can be used with the iO-LINK to power two PROception eyes, without an additional amplifier or power unit. This is not a recommended configuration however, since we cannot guarantee that it will work in all situations. The iO-LINK is designed to power one eye only. All other configurations should include a powered amplifier to ensure reliable operation with iO-LINK.

Using passive splitters can introduce other problems. To power multiple eyes a splitter must have DC power-pass capability to all its outlets. Should one ‘split leg’ be connected directly to a TV receiver, omitting the eye, there is a risk that it will short-out the 9 V power to the eyes on the other leg(s), causing confusion and call-backs. This risk is avoided entirely by using a proper IR-capable amplifier, designed to handle this situation.
