Palmer iller Passive Line Isolation Box with Combo Input

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

The Palmer iller 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 only difference to its sister model wupper is that the Palmer iller is equipped with a combo socket on the input side that can accept both jack and XLR connectors. This eliminates the need for adapter cables.

The Palmer iller was developed for guitar and bass applications; however, due to its high-quality sound characteristics, it is just as suitable for keyboards and hi-fi equipment. The input (XLR/jack) can be balanced or unbalanced and the output (XLR) is balanced. This means that the Palmer iller can also be used to balance unbalanced signals, which allows longer cable runs without affecting the sound. Because of its passive design, the iller requires neither batteries nor phantom power. This makes it extremely failure-proof.

The Palmer iller is a simple, efficient hum killer: you connect it between two devices and the noise is gone. Sometimes it can be that simple!
