DIY: spdif switching COAX to COAX (testing up/down/up conversion)
a home-made SPDIF (digital audio) switch.
it supports 3 optical inputs and 1 coax input. for outputs, it has dual coax/opto (concurrent, same output).
it does not decode any data, it simply switched data at TTL levels and outputs the analog pulse train. just a simple physical repeater (not even really a bridge).
selection is via a 2-bit binary TTL 'address' placed on a molex connector. select 00, 01, 10, or 11 to pick inputs 1 thru 4.
total cost is under $20 in parts (well under that).
in this photo, coax in and coax out is being auditioned on my 'popcorn hour'.
I can hear sound coming from the other end. I guess it works ;)
