Hi all
Hope you can help
I'm wanting to build an audio switcher, for a conference audio rack.
It will have 3x balanced inputs, and route to 1x balanced output. (all connectors will be XLR - these are professional audio devices with +4dBu nominal signal)
I would like to select the inputs via pushbuttons on the front panel, and to have an LED indicating which input is currently live.
I'm quite happy to run relays to switch the audio in and out.
In an easy world I'd just use a rotary switch - however I want the switcher to always return to having input #1 selected and routed when it loses power and powers back on, regardless of which input was selected when it lost power.
Please could you point me in the direction of where I need to look?
Thanks, and have a great holiday season
Cheers
David
