A tip for M-Audio MobilePre USB Users
I just got a hot new mixer, which I will shortly write about. In the mean time, I wanted to just share a quick tip for users of the MobilePre, a beautiful USB-powered audio preamp made by M-Audio, which I use as one of the components in the mixer. I have it both as an output and as an input. To do this, first turn on direct monitoring. You can do this in the volume control, under playback controls. Make sure that under “advanced” you have the “1-channel input” option unchecked. Hook the mixer or whatever you want to use to the line input on the MobilePre. Now the kicker: The two gains on the front control all audio data coming over all inputs, not just the xlr microphone inputs. This really threw me. At first everything sounded all muffled, and in mono. I couldn’t figure it out, it certainly did not seem on par with M-Audio’s respectable reputation. After some fiddling around, I realized this property of the gain controls, which seems somewhat obvious in retrospect. So, first connect the line, and connect
headphones to the headphone out. With the direct monitoring on, you will hear the audio coming over the line-in. Carefully adjust the two gains on the front – one for the left channel and one for the right. Use your brain to balance out the sound until it sounds perfectly balanced. There you go. Turn off direct monitoring, then hook the line-out to your mixer and enjoy. I wanted to post this on my blog in case someone else has this problem, then they will hopefully find it through a search engine and save themselves a few moments’ panic. No, you don’t need to buy a new sound device just to record your beautiful mixer’s output. Have fun!
