The SB-6 is a passive isolator that has been designed to work with both balanced and unbalanced signals. As detailed in the graphs below, the SB-6 is exceptionally linear throughout the audio range and exhibits nearly flawless phase shift even in the lower registers. Very low distortion from -40 dB to +10 dB makes the SB-6 ideally suited for instruments, consumer audio devices, and pro-balanced audio signals, while the compact size makes it easy to integrate in just about any situation.
