Do I need power for this ground loop isolator?

No—this is a passive isolator that uses a 1:1 isolation transformer, so it requires no external power source. Just connect it between the devices causing the hum problem.

Will this affect my audio quality?

A quality 1:1 transformer isolator introduces minimal signal loss and actually improves sound by removing unwanted noise. You should hear cleaner audio without the background hum or buzz.

Can I use this with both XLR and 1/4" connections?

Yes—this 2-channel model has both XLR input/output and 1/4" TRS connectors, allowing you to isolate ground loops on different types of audio connections in the same device.
