DigiOne S/PDIF interface
The Raspberry Pi card is surmounted by an Allo DigiOne digital interface. This high-performance digital audio module is now recognized in the audiophile world, notably thanks to its excellent price/performance ratio. It extends the capabilities of the Raspberry pi card and allows it to output the digital audio stream via a BNC output and an RCA output.
With its two internal clocks, the DigiOne interface offers a remarkably clear signal, as evidenced by its extremely low jitter rate of 0.4 picoseconds. As the jitter is picked up by all elements of the system and is difficult to erase at the cost of further signal inaccuracies, this feature makes the DigiOne a perfect choice for a high-fidelity digital player.
