The DÆ v3.0 Preamp is a complete single channel preamp including a v2.1 Phono preamp (described in the May 23rd, 2020 blog post), three differential inputs (described in the October 23rd, 2020 blog post), an interface to v3.0 Attenuator (described in the July 2nd, 2020 blog post) and an interface to the v3.0 Battery Charger/Power Supply (described in the September 9th, 2020 blog post).

Two of these preamp boards are required for stereo.

I have also designed and assembled an enclosure for this preamp. The enclosure will be the subject of a future blog post.
