		   Hi Guys,

  

 Is there anyone out there who has implemented an audio mixer for expanding the number of unswitched inputs to their audio panel?

  

 Which model did you use and what is your experience?  Alternatively did anyone simply use one (or more) of the unused switched inputs and relabelled (if so how) the switch accordingly?

  

 In my case I have a GMA-347 and need seven unswitched inputs (it comes with five).

  

 Thanking you all in anticipation,

  

 Rodger

Well, I built my own audio panel/intercom, so I guess the answer to your question is 'yes'.



Google "LM324" and "mixer" and you'll see some ideas. Or I can email you the circuit I used. Cost about $5.

Thanks Bob,

  

 That would be fantastic if you sent me the circuit,
