Righto….now I’m getting somewhere. I finally got around to making up the Expresso phantom kit and the contact mic now works perfectly. I get 41V. from the expresso, sound quality is now very good… so it seems like my mixing desk gives too many volts for the cortado. If I want to use it with my desk how do I get around that? (This has been an interesting process…frustrating at times but I’ve learned a lot)
