Hi Freq Noise Issue
1 of 1 found this helpful This is a great way to get into Pro Tools without spending a lot of $$. There is an issue I have seen a lot on the internet which I also discovered - a high frequency noise when the box is activated. It comes out the audio out ports and is a definite no-no on your audio tracks. I saw a video on UTube advocating soldering a ground wire to the circuit board. I recommend that you do not do this. There is a reason why audio circuits are isolated from ground - it improves the signal to noise ratio. If you ground the audio circuit you will decrease your audio performance. The real issue with the mbox is a ground loop issue. I had the problem initially on this box because my computer which powered the box was connected directly to the wall circuit while my audio was going through an amp which was powered by a UPS. My midi ports were also powered by the UPS. This creates a ground loop and results in the high freq. noise. Once I put the wall circuit computer and monitor and the amp on the UPS too the noise went away. This issue can be fixed by taking a few precautions. The mbox can perform brilliantly for a great value!
