Radial Engineering SB-6 helps eliminate background noise from audio systems on two channels, stereo guitar racks, and pedals. Two built-in isolation transformers provide a linear frequency response from 20Hz to 20kHz, while simultaneously removing unwanted sounds caused by ground loops. The dual groundlift switches help further reduce background noise, and a -15dB pad allows you to easily manage high-volume signal outputs without distortion.
