Palmer RIVER iller - Passive line isolation box with combo input
The more complex a setup is, the greater the risk of ground loops. With the Palmer iller Line Isolation Box, things go quiet again, so you can enjoy your sound without hum and buzz.
The Palmer iller is an isolation transformer in a rugged aluminium and steel housing. It separates the ground potentials between two devices, preventing equalisation currents so only your audio is transferred – clean and interference-free. The only difference compared to its sister model wupper is that the Palmer iller is equipped with a combo jack on the input side, accepting both jack and XLR plugs. This eliminates the need for adapter cables.
The Palmer iller was developed for guitar and bass applications; but thanks to its high-quality sonic performance it is equally well suited for keyboards and hi-fi equipment. The input (XLR/jack) can be balanced or unbalanced, and the output (XLR) is balanced. This means the Palmer iller can also be used to balance unbalanced signals, enabling longer cable runs without affecting the sound. Thanks to its passive design, iller requires neither batteries nor phantom power. This makes it extremely reliable in operation.
The Palmer iller is a simple and effective hum eliminator: connect it between two devices and the noise is gone. Sometimes it really can be that simple!
