This is the digital input selection board from one of my earlier digital pre-amplifier prototypes. It features two Toshiba Toslink optical inputs and two additional RCA or BNC coaxial inputs. One (or none) of these inputs can be selected using the SS0..SS2 source select inputs on the µC connector. The remaining 7 pins of this connector are unused. The output is TTL-level S/PDIF. 74HCU04 is on board.

I don't need this board anymore as I redesigned the pre-amplifier some time ago. I'm asking 20€ including international shipping.
