SB-2 Specifications

The Radial SB-2 is a compact passive direct box that is designed primarily for buffered sources such as active acoustic guitar, keyboard and electric bass. A unique stereo-to-mono merge function enhances functionality by enabling stereo keyboards to be connected and mixed mono to save channels in the PA. Upon testing, the SB-2 exhibits exceptionally linear response and low distortion throughout the desired operating range, proving that size does not necessarily follow performance! The compact design provides the traveling musician with a quality direct box that can be depended upon for the most demanding club gigs.
