Radial Engineering SB-1 StageBug Active Phantom Power Guitar/Bass DI Direct Box
Manufacturer's Description
The Radial StageBug SB-1 is a super compact direct box that is designed primarily for acoustic guitars. As evident with the tests below, the compact size and streamlined feature set should in no way equate to lesser audio quality. The SB-1 delivers an exceptionally linear frequency response, virtually zero phase shift, and less than 0.005% distortion at all frequencies making the SB1 an ideal interface for all instruments.
Ultra-compact DI
The design begins with standard ¼ instrument input with a thru-put to feed your tuner or your on-stage amp. The ultra-quiet active circuit at once converts the signal from high to low impedance to reduce susceptibility to noise. The signal is then buffered and balanced for long cable runs to the PA system. 48 volt phantom provides the power, so the SB-1 does not require batteries or external supply to make it work. You simply plug in and you are ready to go!
