Radial StageBug SB-4 DI-boks

The Radial StageBug SB-4 is a compact active direct box engineered for piezo-equipped acoustic and orchestral instruments. Its 5 megohm input impedance softens the harsh transients and resonant peaks typical of bare piezo pickups, while the balanced XLR output carries the cleaned-up signal over cable runs of up to 100 meters without loss. No batteries are needed, since 48V phantom power from the mixing console runs the whole unit, and the steel chassis slips inside a guitar case pocket.

• 5 megohm piezo-optimized input broadens frequency response and tames squawk for a more natural acoustic tone
• Balanced XLR main output plus a buffered AUX out, so the PA and a stage amp or tuner can run at the same time
• High-pass filter, 180° polarity reverse and ground lift for cutting rumble and taming live feedback
• 250 g steel housing in a 114 × 47 × 34 mm case-friendly footprint
