The Radial Engineering StageBug SB-1 is an active direct box that has been specifically designed to provide a quick and dependable connection from your instrument to the PA. In other words, it converts the hi-Z output from your instrument—typically a 1/4" guitar jack—to a balanced low-Z signal via standard 3-pin XLR connector. Balancing the signal reduces noise, enables longer cable runs, and improves the sound quality by properly matching the instrument's impedance with that of the PA. And with 48 volt phantom powering, the SB-1 does not require batteries or external supply to make it work. You simply plug in, and you are set to go.
The active circuit features 220 kilohms input impedance to eliminate problems with loading while delivering a smooth, warm sound to the audio system. This is particularly important when interfacing vintage guitars with low output pickups when you plan to do some recording or re-amping. This unit is also equipped with a -12 dB pad, which reduces input sensitivity of the circuit to enable louder instruments to be used without distortion. To reduce feedback, toggling the 180° polarity switch helps eliminate hot spots on stage that can cause low-frequency resonance.
Made to fit inside a guitar case for players that are on the move, this compact DI box delivers enhanced sound throughput. Although the SB-1 has been optimized for use with acoustic guitars, it is also well equipped to handle electric bass guitars and keyboards.
