Hey guys ... I have just put a couple of spekers around my house, to get background music from a cheap stereo. Trouble is that although I'm not be that concurned with quality ( I have a proper stereo in the lounge ) it's really anoying when I'm listening to stereo dependent music ... 'cos I only get half of it in the bedroom and the otyher half in the kitchen. ... is there a simple way of mixing the chanels together to get two monos instead ?
I would expect any radio (even cheap ones) to have a choice between FM and FM stereo, just because sometimes when you have bad reception in FM, turning to mono helps...
I cant imagine a efficient way to mix 2 channels at that level, it's easy enough at preamp level...
You probably need two speakers in each room so that each will have stereo. Paralleling speakers will probably over-power the amplifier. You probably need a separate volume control in each room.
A solution will be to use stereo auto-transformer volume controls available for your application in AV shops. With their volume turned down slightly, the amplifier will not be overloaded by having two speakers conected to each channel. :lol:
The stereo is an Hitachi AM68d .. and hasn't got a " normal " volume control ... ( it's the type that'll go round and round forever ) ... surely there's a way of using risisters and diods that'll stop the amp from being overloaded ? .. only I got a D at A level physics and can't remember how !! .. thanks

As it's not got a conventional volume control it makes it far more difficult to find a place to make it mono - you really would need a circuit diagram, it's not something I could make suggests for otherwise.
As for 'overloading', I'm presuming you mean adding extra speakers?, the easiest way is to add the extra speakers in series with the old ones - this will reduce power, but prevent your amp blowing up.
