I have bougth this one to find out how good it works. Great one, it works with a Neuman u87 AI perfect. So i decide to buy a twin finity 4-710d. Next days it will comes from my dealer.The UAD 2 Solo from this Bundel i have bought is very usefull too. So i believe someone ask himself why me is giving 4 Stars for this and other products of UA ? The whole Videos, Handbooks, Hints are all in English. I miss a German translation :(. German translation will makes thinks better understanding and working for me. Great work UA, thx for that.
