So you have 4 remotes all lined up for your precious system and no-one else can use it.
A proper sensible easy-to-use programmable remote can sort it all
There are many cheap ones out there and we dont do them, life's too short to spend fixing them
Press Sky, it will turn on your tv, projector, sky box and amplifier, whatever you need, and change it to the correct input
Select bluray and it will change all the necessary inputs, it's easy
There are different versions to cover different installation layouts, and you can also control systems with a tablet, although this is a gimmick just now, controlling a music system from a tablet/phone makes sense for choosing music but why would you want to lift an ipad to control the tv volume??
A ProControl will be between £ 670 and £950 complete and sorts it all, reliably, every time.
