Is your audio still plagued by hum and buzz?
Using multiple plugs within your audio chain means separate earth/ground points. These multiple earth or ground points cause a ground loop problem. This creates an unwanted chain of noise, buzz and distortion.
Struggle no more. iFi’s iDefender+ provides the simple, effective solution you need.

Computer Noise through Focusrite 4i4
Bought this to try and eliminate computer noise from screen refreshing, mouse movements etc. through my Focusrite 4i4. The focus rite has a separate power supply but is still capable of being powered from USBC. I put the defender in between and fed the power to that rather than to the Focusrite and the problem was cured. The only issue is that it is not the most physically stable connection to the computer so tends to cut out if I tilt the screen sometimes.
