There are at least three options for converting analog audio at a local plate to Dante. You can use a product like the Attero Tech unDX2IO or unD3IO 2-gang Dante wall plates. These devices are PoE powered and move analog audio onto the Dante network right at the wall plate – removing the need for analog wiring in the wall. If this is not possible, analog to Dante interfaces like the Stewart Audio NetAV I/O or the Attero Tech unDIO2x2 or unD4I can often be located in a wall box to make the analog to Dante transition and still minimize analog wiring in the walls. Finally, if analog wiring in the walls cannot be avoided, Attero Tech, Stewart Audio, and Symetrix have a number of analog to Dante I/O interfaces in a variety of channel counts for this purpose. You can also use the Audio-Technica Dante-enabled microphones in some applications and eliminate the wall plate altogether.  Audio-Technica  just released the ATND8677 microphone base (not introduced at the time of this example project) which is a great way to get a gooseneck microphone directly on the network.
