I bought this along with the HT - C5500 and it worked straight out of the box.... No fiddling about or lost signal.
It does indeed still require speaker cables between the two rear speakers to be connected to it, as the Unit itself is the "Wireless Receiver"
But you DONT need to have cables coming from your surround sound system, to the rear speakers anymore.... thats the whole point of this eh?
If you are the sort that has a bit of common sence, then you would place that "Thin" Rear Cables underneath the skirking board or under the carpet, to hide the cables... and you would place the Wireless unit where it wont be seen.... Seemples eh?
This unit saves you having to Route the very long rear cables from your Surround System at the front of your room, all the way back to the other end of your room, which can be a bit tricky and hard work depending on your layout.... so this unit will save you that hassle where you can place your speakers where you want at the rear of the room, and not having to worry about where that cables will go from the surround system to them....
This is a 'No-Brainer' tip to the reviewers here that had negative comments about this unit... they should have read its description a little bit more eh?
It works perfect, and I have no cables showing and the unit is placed over 4M from the Sussound system, so I am very, very happy with it.
Buy with confidence!
