The Lambden Audio HD2 Hum Destroyer is suited to musicians and engineers tackling unwanted hum in audio systems.

With two independent channels it can process either dual mono sources or a single stereo signal making it useful for live sound studio recording DJ setups and playback systems. Its passive design requires no batteries or external power allowing straightforward plug-and-play operation wherever you need it. Dual 1/4" TS/TRS inputs and outputs provide broad compatibility with a wide range of audio equipment while the internal isolation helps reduce unwanted noise while preserving your original signal. Finished in a compact black enclosure with protective side panels the HD2 is easy to integrate into permanent installations and portable rigs alike.
