Eliminate hum and buzz between your laptop and the PA
A professional audio isolator built around an isolation transformer that breaks ground loops, the usual cause of the hum and buzz you hear when a laptop, phone, mixer or media player is plugged into a powered sound system.
It takes a 3.5mm or RCA input and delivers a balanced XLR output ready for the sound desk.
It is fully passive, so there is nothing to power or set up, you simply patch it inline and the noise is gone. The metal housing is made for repeated event and touring use and fits any audio case.
