Piano 2.1 Audio Card

The Piano Map 2.1 uses a 2 PCM5142 DAC Ic with integrated DSP. Its PurePath software can be used to create specific filters and other audio functions.
The table will be pre-programmed as output 2.1 (you can create your own custom design, load it on the table and access frequency xover directly from linux).
As for hardware, the digital and analog side has been divided with the LDO and we feed the analog side using a high-performance LDO. LT3042 has very low noise and ultra-high PSRR. Basically, each card has 4 LDO (2 for each DAC ic).
