Radial Engineering Twin-Iso Balanced Line Isolator – Dual-Channel Transformer-Isolated Audio Interface for Ground Loop Elimination and Clean Line-Level Signal Distribution

The Radial Engineering Twin-Iso Balanced Line Isolator is a professional dual-channel transformer-isolated audio interface designed to eliminate ground loops, reduce noise, and ensure clean, stable line-level signal distribution in studio, live sound, broadcast, and installation environments.

The Twin-Iso provides two independent channels of balanced line isolation, making it ideal for stereo or dual-mono applications. Each channel uses a high-quality Jensen transformer to provide galvanic isolation between input and output devices. This breaks unwanted electrical connections that commonly cause hum, buzz, and interference when multiple audio systems share different power sources.

Designed for versatility, the Twin-Iso is commonly used to connect mixers, audio interfaces, DJ systems, keyboards, playback devices, and stage equipment to PA systems or recording gear. It ensures that signals remain clean and consistent even in complex setups with multiple interconnected devices.

As a fully passive device, the Twin-Iso requires no external power and delivers transparent audio performance with minimal signal coloration. Its transformer-based design preserves frequency response, dynamics, and headroom while providing complete electrical isolation.
