It makes a lot of sense.
 
I do something (almost) the same - but in my case the amps are "remote", turned on/off by X-10 appliance modules, and I use KAT5 to carry the signal "long distances" at line level, and only have "short distances" of speaker cable.
 
Again, controlled by a Pronto, in my case using an ageing X-10 infrared receiver.
 
I don't know enough electics to trust myself to install relays properly :-)

Hi Peeps.

 

Ok – here are some questions I have:

 

  • I want to have a serial / parallel port interface, with say, 8 relays on it, which I can turn off / on using some simple program (I aren’t a programmer – so I’d struggle to get somewhere with that side of things..)
  • Multi-room hifi … I want to be able to split a source signal (from something such as a cd player / mp3 server (linout)) into 4 outputs, and then feed each output to a different amplifer – can something be done? – maybe use the ‘Kat 5’ system and a hub?

 

What I want is a multi-room hifi, but I refuse to pay nearly a grand for an amp … (and I’d enjoy doing this way a lot, lot more – and it’s a hug learning experience.!!)

 

I want to control which amp is used by using my pc (output to my tv (which is done)) using a Phillips pronto + an IR device on my PC (can control basic functions of pc this way) and switch amps on or off (hence relay board.. – much like a car stereo install – can have several amps, controlled by a signal wire ..(only amps turn on, once you’ve got the stereo turned on..)

 

I hope this makes sense… it does to me ;o)

 

If anyone can help me, I shall be eternally grateful.. !

 

Many thanks in advance.

 

Jonathan.
