My mbox mini makes a big static noise that overpowers everything, my monitors and headphones

Check all connection. Look for magnetic interferes. Be sure there are no other transmitting lines near the speakers or cables

Blown or defective Headphone Amp IC or alternatively a defective Pot. Either way only AVID can fix it for you.

Outside parts and service is impossible.

Fuse would have NOTHING to do with the problem. Make sure to use balanced audio lines... XLR or TRS to mics or other devices.

The mbox mini is usb powered, wont work without power so your mac or pc must be powered on and connected. The blue led will be on when powered. Assuming you have the the appropriate cables, you want to make sure the condenser is plugged into the Mic/Line input. (Input 1 on the back of the mbox mini). All condenser mics require phantom power, so engage the +48V switch. Also make sure the DI (direct input) switch is not engaged. The input gain control is located on the front of the mbox... There needs to be speakers connected to the 1/4 output jacks on the back of the mbox or headphones on the front for sound output. Use the large knob for monitor volume control.
In protools: Create a Stereo Master fader track
Create a mono audio track
Set the input of the mono audio track to Mic/Line 1 Arm the track for record (click & make sure the R is red)
You should getting levels and sound output from your condenser.

Make sure you turn the Phantom power on the Mbox2 on as the Shure 87A requires it being a condenser mic.Make sure you use XLR mic cables. These are just things to check on.

Try increasing the latency. Depending on your computer, it may not be able to handle low latency levels. Latency is a measure of the delay between the time you make a sound and the time the computer records that sound. With the Mbox mini, the unit for latency is the number of samples the driver collects before sending them to an application as input. Lower latency can make recording easier and more accurate, but not all computer systems can operate at the lowest latencies without introducing noise. Open the Mbox mini dialog and select the latency tab. experiment with higher latency levels and see if it goes away. This is what the dialogue might look like. another solution would be to try a different DAW. I had the same problem with my Fast Track Pro in ProToolsand it worked fin on Reaper, Garageband and Logic.

Uh, that has nothing to do with the headset--it's due to chat in the Xbox controller. No headset is going to be 100% quiet because they are self-powered.

could be the krk monitors try using headphones and see if theres a difference.

me too! but not with my head phones all the way down. for some reason this static ends up on my recordings too. i dont get it. it is like short bursts of static every 6 seconds or so. i would greatly appreciate any information if you have found a solution yet. THANKS!
