Input selector is integrated with PCM2704 USB DAC/receiver which can be used also as USB to SPDIF transport for external iDAC (with 16bit/48kHz restriction).
Selector have 4 main positions:
- Analog line 1
- Analog line 2
- USB input (PCM2704 DAC)
- SPDIF input (external iDAC)
In SPDIF input mode we can bridge SPDIF_IN with SPDIF_OUT on the back of the selector board and audio signal will flow from USB threw external iDAC board.
