GLE-20W - 12V / 20 watts DC/DC converter – ground loop eliminator

Eliminate Noise & Power Your Audio System with Confidence

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 the unwanted hum, buzz, or interference caused by ground loops.

What is a Ground Loop?

A ground loop occurs when there are multiple paths to the ground in an electrical system, leading to unwanted current flow between connected devices. This typically happens when different pieces of equipment are plugged into a same power source (like a battery power distribution system) and to a common device such as a digital audio recorder, creating a small voltage difference between their ground connections. This voltage difference can introduce an audible hum, buzz, or interference into your audio signal, significantly degrading sound quality.

How Ground Loops Affect Your Audio Signal

Ground loops are a common issue in professional and home audio setups. They can cause:
✔ Audible Hum & Buzz – Audible noise can be heard in your audio recordings.
✔ Unwanted Interference – Radio frequency interference (RFI) and electromagnetic interference (EMI) can infiltrate your signal chain.
✔ Degraded Audio Quality – Unclean power can result in inconsistent performance and reduced dynamic range in your recordings or live sound setup.

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 features include:

Ground Loop Elimination – Effectively removes hum, buzz, and noise caused by grounding issues.
DC-DC Power Conversion – Converts 9-18V DC input to a clean, isolated 12V DC output, making it ideal for powering sensitive audio equipment.
High Power Handling – Delivers up to 20W of regulated power to support a variety of devices.
Compact & Lightweight Design – Perfect for portable setups and integration into existing systems.
Robust Build Quality – Designed for reliability in demanding professional environments.

With the Audioroot GLE-20W, you can say goodbye to unwanted noise and enjoy a clean, professional-quality audio signal—whether in the studio or on set.
