The Glensound GS-ET01 is a portable single-channel audio isolation transformer designed to solve hum, ground loop and common-mode noise problems in professional analogue audio systems. Originally developed for outside broadcast applications where cheap DI boxes failed to cure interference issues, it uses a high quality audio transformer and a unique variable centre tap arrangement to provide effective galvanic isolation in demanding real-world environments. Its compact format makes it a practical troubleshooting and permanent-installation tool wherever a single problematic audio line needs cleaning up.
The GS-ET01 provides one isolated audio channel for insertion between source and destination equipment where hum or interference is present on a balanced analogue line. The earth lift and centre tap switching arrangement allows engineers to optimise the grounding relationship between connected devices, which is especially useful when linking remote venue feeds, stage positions or OB circuits back to the main system. It can be used alongside other audio interfaces and audio products wherever galvanic separation is needed to improve analogue signal integrity.
In daily use the Glensound GS-ET01 gives engineers a simple and effective way to remove buzz, hum and grounding-related noise from a single audio path without redesigning the wider system. It is particularly valuable in outside broadcasts and live event setups where equipment is spread across distance and powered from different mains sources or earthing schemes. For broadcasters and live sound teams needing a reliable single-channel isolation tool, the GS-ET01 provides a compact, field-ready solution within the wider Glensound broadcast audio range.
