Reply to Question about VCI-400's volume output

Hey I want to buy a VCI-400, but before then I wanted to know how good it's volume output is when converting the XLR to RCA. I read that the conversion causes a volume drop and I wanna be able to mix in with other DJ's on CDJs. Will this be a problem with this controller? Also is it possible to download the Ean Golding mappings on a non Ean Golding version of the controller, as the store is out?
