The Radial Engineering StageBug SB-1 Acoustic 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 connectors. 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 220ka„¦ 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.
