Hi all. It’s Stephen here from ezsound. I’m very happy to announce that the ezsound-6x8 soundcard is now live on Crowd Supply. Thank you to everyone who subscribed during the pre-launch phase!

We began this journey because commercially available multichannel soundcards made design choices that we weren’t happy with. Ezsound 6x8’s design always aims at optimum sound quality, rather than impressive-on-paper figures that you’ll never hear. But it also aims to be cost competitive with other commercial offerings, and we feel like we’ve hit the sweet spot. It hasn’t been easy, with some serious technical barriers along the way, but we think the result is worth it.

ezsound 6x8 features:

• 6 single-ended inputs and 8 single-ended outputs at 96 kHz
• Isolation from the Pi's power supply to minimize digital noise and solve the ground loop problem
• Modular board design allowing maximum flexibility for mounting in an enclosure
• Drivers already included with Raspberry Pi OS
• Support for I/O via 2.54 mm headers rather than RCA sockets

It will be available in two versions: one with the RCA sockets pre-soldered, and one with the RCA sockets included separately. Schematics and PCB layout files will be released publicly under a permissive license when the boards are shipped to Crowd Supply for delivery to backers.

I’m personally very excited to get this product into the hands of audio hackers around the world and I’m looking forward to seeing what weird and wonderful projects the maker community builds around it.
