Audio Ground Loop Noise Isolator – Hum & Buzz Eliminator

Stop Ground Loop Hum & Electrical Noise Instantly

Hearing a constant hum, buzz, or unwanted electrical noise from your studio monitors, mixer, or PC audio setup? Before replacing expensive gear, eliminate the root cause.

The PRO MAX2 Passive Audio Ground Loop Isolator can help reduce ground-loop hum between connected audio devices. Its passive transformer-based design isolates the audio ground connection without batteries or an external power supply.

Why PRO MAX2 Outperforms Basic Isolators

• All-In-One Connectivity: XLR, 6.35mm (1/4-inch) and RCA connections in one unit, reducing the need for multiple connector-specific isolators..
• Dual-Channel Stereo Isolation: High-fidelity audio transformers deliver clean 2-channel sound.
• Pro Audio Control: Built-in Ground Lift switch to break ground noise, plus a -15dB PAD to manage high-level signals.
• 100% Passive & Heavy-Duty: Plug-and-play transformer design requires no batteries or external power, housed in a shielded metal chassis.
