Palmer enz 2-Channel Unbalanced Line Isolation Box

When connecting a media player or a laptop to a HiFi- or PA system, you often experience noise such as hum and buzz caused by ground loops. With the Palmer enz,

With the Palmer enz, you can be sure that such annoying interference signals do not occur anymore!

The cause of this interference lies mostly in ground potential differences, which result in stray DC currents via the audio lines. The solution is to place a transformer between the two devices to isolate the ground line. Palmer enz has two of these transformers for its two channels. Its inputs and outputs are RCA sockets, which are common for HiFi and consumer equipment. However, the sound quality will also satisfy professionals, since the sound remains unaltered.

This makes the enz Line Isolation Box a useful problem solver for home or car HiFi systems and PA systems from conference rooms to nightclubs. A Line Isolation box simply belongs in every DJ's kit. Whenever there is buzzing and humming, the Palmer enz brings silence with a touch of a button.
