Estimated delivery time: 1–2 weeks.
Product description
The Audioroot GLE‑20W is a high‑quality ground loop eliminator and power converter designed to provide clean, noise‑free DC power to your audio equipment. This essential device is engineered for professional audio setups, ensuring your gear operates without unwanted hum, buzz, or interference caused by ground loops.
What Is a Ground Loop?
A ground loop occurs when there are multiple paths to ground in an electrical system, leading to unwanted current flow between connected devices. This typically happens when different pieces of equipment are plugged into the same power source (such as a battery power distribution system) and connected to a common device like a digital audio recorder. Even a small voltage difference between grounds can introduce audible hum, buzz, or interference into your audio signal.
How Ground Loops Affect Your Audio Signal
Ground loops can cause:
-
Audible hum and buzz
-
Unwanted interference (RFI/EMI)
-
Degraded audio quality and reduced dynamic range
How the Audioroot GLE‑20W Solves the Problem
The GLE‑20W eliminates ground loops by isolating the power and breaking the unwanted ground connection while ensuring a stable and regulated DC power supply to your equipment. Key benefits include:
-
Effective ground loop elimination
-
DC‑DC power conversion from 9–18V input to clean, isolated 12V output
-
High power handling with up to 20W of regulated output
-
Compact and lightweight design for portable setups
-
Robust build quality for demanding professional environments
With the Audioroot GLE‑20W, you can eliminate unwanted noise and maintain clean, professional‑quality audio — whether in the studio or on set.
