Description

The more complex the setup, the higher the chance of ground loops. With the Palmer wupper Line Isolation Box, everything is quiet again so you can enjoy your audio without humming and buzzing.

The Palmer wupper is an isolation transformer in a robust aluminium and steel housing. It separates the ground potentials of two devices so that equalising currents are prevented and only your sound is transmitted - clean and without interference.

The Palmer wupper was developed for guitar and bass applications, but its brilliant, unaltered sound is just as suitable for keyboards and hi-fi equipment. The inputs and outputs with jack connections can be balanced or unbalanced. This means that the Palmer wupper can also be used to balance unbalanced signals, which allows longer cable runs without affecting the sound. Due to its passive design, the wupper requires neither batteries nor phantom power. This makes it extremely failure-proof.

The Palmer wupper is a simple, efficient humming killer: Connect it between two devices and the interference is gone. Sometimes it can be that simple!
