Radial StageBug SB-6, Stereo Line Isolator, Passive, Radial Item R800 0160.

The StageBug SB-6 is a two-channel passive audio isolator designed to accommodate both balanced and unbalanced signals and helps remove noise from two-channel audio systems, stereo guitar racks, and pedalboards. Two onboard isolation transformers provide a flat frequency response from 20Hz to 20kHz, while removing hum and buzz from ground loops. Dual ground lift switches help further reduce noise, and a -15dB pad allows you to handle high volume outputs without distortion.
