What you do is is to try basic troubleshooting. Break down the problem until you identify what it is the problem. Try using a different mic and/or non phantom powered dynamic mic. Try a different cable. Try the other channel of the 0404. Try using a line level source such as a guitar/bass, drum machine, keybaord, Ipod ect...

E-MU has excellent tech support. You can call them and have them walk you through it.

Okay I took your advice and plugged in my dynamic with the cable I'm using, and it works perfectly. I also already tried both inputs and same exact results.

Here's the thing--when I turn on phantom power with the DYNAMIC, I still get the exact same level of input. I always thought phantom power should affect the signal when using a dynamic.

Ok, It appears that there is a problem with your unit in regards to phantom power. Assuming that you bought your 0404 new from a authorized dealer, contact E-MU to obtain an RMA for repair or replacement.

No, the point is that, as long as it is correctly wired, there should be no difference having phantom power on or off when using a dynamic mic. In this way, you can use any combination of condenser and dynamic mics on a mixer that has only a global phantom power switch. Don't try it with ribbons, though.

Either the phantom power on your 0404 is not working correctly, or your NT1-A is faulty.

Thanks a lot guys! I'm heading to guitar center right now to test the interface with new mics and pinpoint the problem.

The help was much appreciated.
