Radial StageBug SB-4 Piezo DI



Radial StageBug SB-4, Compact Active DI with Piezo Input, Radial Item R800 0140 00.

The Radial StageBug SB-4 is a compact active direct box that has been optimized for use with piezo transducers and is small enough to fit inside an instrument case. Unlike typical direct boxes, the SB-4 features a very high 5MOhm impedance that smooths out troublesome peaks that are common with piezo transducers, retaining the natural tone of your piezo-equipped instrument when amplified through a PA system. The active circuit balances the audio signal to enable long runs of up to 100 metres without signal loss while delivering spectacular linearity and low distortion throughout the audio range.

• Active DI optimized for piezo transducers
• Smooths out peaks and eliminates squawk
• Powered by 48V phantom power, no batteries required
• Compact design fits in your instrument case
• Aux-out connection for a stage amplifier
• Standard XLR output to feed the PA
