Radial StageBug SB-4 Compact active DI for piezo pickups, low-cut filter, 48V phantom

The Radial StageBug SB-4 is an active direct box professionally enhanced and designed for use with piezo electric transducers just like violin, upright bass, classical guitar and mandolin. The Radial StageBug SB-4 comes with a high 5-meg-ohm input impedance that at once broadens the frequency response and at the same time it is reducing the squaw and peaks that are encountered most of the time with piezo devices. This is integrated with a high pass filter capable of rolling off the excessive bass gently. The unique AUX output is buffered for enabling the enable high impedance sources to feed amplifiers and pedals not needing to interact with the input impedance. About the circuit design, it is given an extra attention, that's for ensuring the critical listening range and a noise floor that approaches -100dB. These all features are combine and that makes this Radial StageBug SB-4 a excellent and wonderful solution for acoustic and orchestral instruments of all types.

The perfect companion for piezo instruments

The StageBug SB-4 allows you to retain the natural tone of your piezo-equipped instrument when amplified through a PA system. Unlike typical direct boxes, the SB-4 features a very high 5 meg ohm impedance that smooths out troublesome peaks that give piezo transducers a bad name. This higher impedance also broadens the frequency response for a more natural and pleasing sound. The active circuit balances the audio signal to enable long runs up to 100 meters without loss, while delivering spectacular linearity and low distortion throughout the audio range. Output connections include an aux out for a stage amplifier plus a standard XLR output to feed the PA.

Control feedback on stage

To help eliminate feedback on a live stage, the SB-4 is equipped with a high-pass filter and 180° polarity reverse switch. The high pass filter eliminates excessive bottom end which in turn reduces resonance that can cause the instrument to vibrate. The 180° polarity reverse helps reduce acoustic hot spots on stage by changing the phase relationship between the PA system and room acoustics which can combine at certain frequencies to create peaks.
