The Radial StageBug SB-6 is a high performance 2-channel passive audio isolator designed to accommodate both balanced and unbalanced signals and work effectively at eliminating noise when used with instruments, electronics as well as professional line-level devices. The design begins with 0.25'' TRS inputs and outputs to accommodate both TRS and mono type connectors. The unique circuit retains the balanced signals or automatically converts them from hi-Z to lo-Z (0.25'' mono to TRS) or lo-Z to hi-Z (1/4''TRS to mono) depending on the connector in use. You simply connect and the SB-6 does the work for you. Inside are two ultra-linear Eclipse transformers that sound great as they deliver ruler flat performance from 20Hz to 20kHz. This is augmented with a -10dB input pad to handle extra loud source devices and a polarity reverse on output B for phase aligning stereo signals.
