Eliminating hum and buzz caused by ground loops for a variety of audio signal types, the StageBug SB-6 Isolator from Radial Engineering is a 2-channel device that features 1/4" inputs and outputs for both Hi and Lo-Z signals, with the ability to convert one to the other depending on the connectors in use. Its dual linear Eclipse transformers are designed to provide flat response from 20 Hz to 20 kHz, and provides you with a phase reverse switch for phase alignment of stereo signals as well as a -15dB pad.
