Tell me about adding a ground lift
Discussion
A ground lift breaks the ground connection in an audio cable to eliminate hum from ground loops (e.g., between gear and amp). Use a 3-to-2 prong adapter or a DI box with a lift switch. Test it, but never lift ground on AC power cords—safety first, or risk shock. If it fixes noise, that's your culprit.
No. This amp is powered from a 2 prong cord, neutral is tied to the chassis limee an aa5 radio.
