Radial Engineering SB-1 - Active DI with an ultra-compact design suitable for acoustic guitars and bass guitars. Its ultra-quiet active circuit simultaneously converts the signal from high impedance to low impedance to easily reduce noise production. The 48V phantom power ensures the DI is powered, so the SB-1 does not require batteries or an external power source to operate.
