Radial Engineering SB-6 Isolator Compact Passive Stereo Isolator for Balanced or Unbalanced Signals

The Radial Engineering 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, consumer electronics as well as professional line-level devices.

The design begins with 1/4" 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 (1/4" 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 20 Hz to 20 kHz. 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. As the circuit is passive, no power is required – simply plug in and play. As with all Radial products, the SB-6 is made in Canada and features 16 gauge steel construction for use on the road and finished in a durable powder coat finish.

These features combine to make the SB-6 Isolator a wonderful solution to help rid system noise in two channel audio systems, stereo guitar racks and pedalboards.
