What Is It?
The Labgear HDU681/S is an eight way aerial amplifier with multi inputs. It is designed to increase and improve FM radio, DAB radio, CCTV, VCR/DVD, satellite and terrestrial TV signals to up to 8 televisions/radios around the home from one location (e.g. loft).

How Does It Work?
The Labgear HDU681/S combines TV, FM, DAB, CCTV and satellite signals on to one down cable feeding face-plates located near main AV equipment location (e.g. living room). The return cable from VCR/satellite box to loft box feeds up to 8 other viewing locations around home with AV signals.


For connection tips: Labgear HDU681 and HDU641 Connection Diagram.

 

SkyPlus and SkyHD
The Labgear HDU681/S has the LNB1 and LNB2 input and downlinks required by SkyPlus and SkyHD.

Remote Control?
The infrared extender feature gives control over different AV sources from any viewing/listening location in conjunction with
SLx Link (s). The Labgear HDU681/S has an integrated digital bypass - the infrared extender works in conjunction with Sky™. If you would like to use the extender with other devices you can, but you need to use either an Omni Link or a Bluedelta Smart Blaster to power the link and rebroadcast the remote control signals.

Anything Else?
The Labgear HDU681/S has an Integrated UHF pre-amplifier and an integrated power supply. It has a LNB power indicator and silver-grey metallic finish. The Labgear HDU681/S is fully screened - ideal for digital satellite. Distribution of output from a set top box, DVD or VCR requires you to send a return path UHF signal to the loft - the Labgear HDU681/S has an up link in socket for this. This up link is important as when using a Labgear HDU681 distribution box, there will be no signal at the outputs unless the circuit is completed by linking the downlink output to the uplink input after the signal is passed through your satellite receiver. This is so that the satellite signal (and video signal if required) can also be distributed around the house. If you are not connecting to a satellite receiver, then you need to set the switch on the top of the Labgear HDU681/S to UHF & CCTV only.

The Labgear HDU681/S is often used with the
SLx Link , the Global Link or the Bluedelta Smart Eye . See also Sky Remote Controls .

If you need F-Plugs, coaxial plugs, crimping tools or other installation accessories please see our
Coaxial Accessories section.

You may also need a 
Labgear PSW351T or a Labgear PSW241 . These allow separate feeds to and from the Labgear HDU681/S, giving a socket for RF, two F Plug sockets for Satellite TV and a FM/DAB Digital Radio socket. The PSW351T also provides both a return path and a telephone socket (ideal for Sky Plus and Sky HD).

I moved into a new house and had to replace all the coaxial cabling in the place. So I took the opportunity to and install this.
The sky satellite dish feeds directly into the loft luckily, so I just connected three cables from the loft to the living room (2 that do both Sky signals, the aerial and our DAB aerial and 1 for the return of the decoded Sky signal). My other TV's see the Sky as an analogue channel, but the Freeview comes through as normal digital. Also the Sky Magic Eyes work very well in every room, so we can control the Sky Box from any room in the house. I'm well happy with this as it's a lot cheaper than multi-room which we were looking at putting in.

I've been using the HDU681 for about 2 weeks now and so far it's been great. The Freeview TV picture perfect and the signal is being distributed to six other rooms. It was very easy to install in the loft and connecting up the cables using the F-connectors is also pretty easy. Before I decided to do this myself I was quoted £350 for the job by an installer, so I've saved myself a packet too.
