I just bought the Alesis I02 Recording interface and Sterling Audio ST51 Microphone. I am using a Dell PC running Windows XP. I use Mixcraft 3 to record (old, I know). When I hooked everything up the way the little instructions said, i started recording, and, at first, there was no noise. After downloading the ASIO4ALL v2 driver off of the Alesis website, I noticed that if i flipped the "+48 v" switch to 'on', I could barely hear my vocals, though they were very crackly. If anybody could help out, it would be greatly appreciated. Thanks!
