Labgear distribution amplifiers

Distribute your satellite TV, UHF TV, VCR and DVD around your home with this distribution unit by Labgear. Two versions are available, the HDU641S (previous model MRX352) and the new Labgear HDU681S(previous model MRX390). The HDU641S delivers to the main set-top box location plus 4 other outlets, ie 5 in total. The HDU681S (MRX390) delivers to the main set-top box location plus 8 other outlets, ie 9 in total. Both have Infra-Red pass through, providing a return path for IR signals in a remote room. This means that with the addition of a HandyLink set, not only can you watch the VCR in a remote room but you can also control it using your existing IR remote control.

Modulated CCTV, FM radio and DAB can also be distributed via these units. Both units have LNB1 and LNB2 input and downlinks required by SkyPlus and SkyHD (see photo to right).

If you want to expand your system beyond the 8 TVs offered by the HDU681S, then add another HDU641 or HDU681S and split the uplink between the two of them using a Channel Plus splitter/combiner.

NB: These are switchable versions of the HDU amplifiers. They have a switchable direct internal connection between the UHF antenna and CCTV inputs to the distributed TV outlets. To allow the output of a VCR and set-top (Sky) box to be distributed to all TVs the UHF signals must be fed to the uplink input (via the downlink usually). This is to allow the remodulated output of a VCR and set-top box to be distributed.

Wiring schematics: Two Sky box locations, only one location to be used.

If you have two possible locations and you intend using just one of these and not the other then follow this schematic.

Wiring schematics: Two Sky box locations, both locations to be used

This is suitable for "Sky Multiroom", where you have both a SkyHD box and a Sky Plus box, or Sky Plus and Sky digital, or a combination. In the schematic shown, the Sky box at main location 1 would normally be the digibox that would be controlled by an IR relay system such as Labgear Digilink

Wiring schematics: One location with two SkyHD (or two Sky Plus boxes)

If you have two SkyHD or Sky Plus digiboxes located in the same place, say in an AV cupboard near to the TV distribution amp, then follow this schematic.

Although it is possible to distribute your DVD around the home by modulating the signal through the VCR, this often causes a poor image due to interference. It is better to use a separate modulator, as you must do for any CCTV signal that you put onto the system. Click here for a range of high quality modulators.

IR control multiple IR sources

The HandyLink IR control system consists of a driver set (MRX120) which sits beside the TV/Digibox/VCR/etc and a set top target IR receiver in the remote room. The IR target puts the IR on the co-ax cable; the base driver unit takes the IR signal off the co-ax and re-transmits the IR signals to the equipment.

The HandyLink system relies on a continuous path for the signal to be passed from the sensor to the IR emitter near the TV. It is important that you use "non-isolated" TV outlets at both ends (see Labgear range of outlets). Extra set top receivers (MRX110) are available for additional rooms.

IR control single Sky box

If you only require IR control of a Sky (or Sky+) digibox, then you can use a simple devices called tvLink. This is a modified IR target that works directly with the Sky digibox without the need for a base unit. tvLINK will not control other items of equipment; for this you need HandyLink.

IR control Sky box and Sky+ box

For this arrangement you will need a Global Plus Combiner, to ensure control of both boxes individually. You will also need a tvLINK in each remote room.

IR control of multiple SkyHD and Sky+ boxes

To control more than one Sky+ or SkyHD boxes you will need a Global Super Plus Combiner, to ensure control of all boxes individually. You will also need a tvLINK in each remote room. For wiring schematic see above.
