Developed for guitar and bass application but also great for keyboards and hi-fi equipment, the Palmer RIVER wupper is a single-channel, line-isolation box used to eliminate ground-loop hum and interfering signals when connected between two devices. RIVER wupper is equipped with a 1/4" connector on the input side and a 1/4" connector on the output side. Both the input and output can either be balanced or unbalanced.
RIVER wupper features a simple and failure-proof passive design that requires no battery. It utilizes galvanic-isolation technology via its transformer to preserve the sound quality of your audio channel.
Engineered in Germany and built to last, the unit is virtually indestructible thanks to its rugged, aluminum-and-steel casing and reinforced connectors.
