The Radial StageBug SB-6 Isolator ($115 MSRP) 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, consumer electronics and professional line-level devices. The SB-6 Isolator is offered as a solution to help eliminate system noise in 2-channel audio systems, stereo guitar racks and pedalboards.
The design begins with ¼-inch 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 (¼-inch mono to TRS) or lo-Z to hi-Z (¼-inch TRS to mono) depending on the connector in use. Inside are two ultra-linear Eclipse transformers that, according Radial Engineering, deliver “ruler flat performance” from 20 to 20k Hz. This is augmented with a -10dB input pad to handle excessively loud source devices and a polarity reverse on output B for phase aligning stereo signals. As the circuit is passive, no power is required; users simply plug and play.
As with all Radial Engineering products, the SB-6 is made in Canada and features 16-gauge steel construction for use on the road and is finished in a durable powder coat finish.
