Radial Stagebug SB1 Active DI Box

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! Features Active direct box for acoustic and passive bass Ultra compact to fit in your guitar case Plug & play easy to use feature set 48V phantom powered, no batteries needed!
