Palmer PLI03

 

The Palmer PLI03 is a dual channel isolating transformer designed to help to solve specific problems which may arise when connecting computer sound cards to stereo/recording systems. Firstly, the Palmer PLI03 can safely eliminate any ground loops. Also, by isolating digital and analog ground, it eliminates crackling and hissing noise originating from the computer's high-frequency clock signals. The phono sockets on the inputs/outputs make the Palmer PLI03 a convenient tool to liminate ground loops in hifi/stereo systems. These are sometimes caused by community antenna installations. In car hifi systems, it can also eliminate unwanted ground  noise.
