    Product Description

    A compact active direct box optimized for your onboard piezo pickup, the Radial StageBug SB4 Active DI offers a better sounding, more compact DI for violins, dobros, mandolins, cellos, upright basses and other piezo amplified instruments. The design begins with a 1/4 inch input for the instrument pickup. Unlike typical direct boxes that have a 1meg-ohm input impedance, the SB4 features a very high 10meg-ohm impedance that smoothes out troublesome peaks that give piezos a bad name.

    Radial StageBug SB4 Active DI Features

    • Active DI optimized for piezo transducers
    • Smoothes out peaks, eliminates squawk
    • High pass filter eliminates resonance
    • Ultra compact to fit in your guitar case
    The higher impedance also broadens the frequency response for a more natural and pleasing sound. The active circuit performs the high-to-low impedance conversion and balances the signal to enable long runs upwards to 100 meters without loss, delivering spectacular linearity and low distortion throughout the audio range.

    To help eliminate feedback on stage, the SB4 is equipped with a high-pass filter and 180 degrees polarity reverse switch. The high pass filter eliminates excessive bottom end which in turn reduces resonance that can cause the top of the instrument to vibrate. The 180 degree 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. Reversing the polarity eliminates the acoustic peak without resorting to severe equalization which only serves to compromise the natural tone of the instrument.

    Connections include an AUX out for a stage amplifier plus a standard XLR output to feed the PA. Power is derived from the console's 48V phantom, thus eliminating the need for batteries or external supply. One simply connects, turns on the phantom power and plays!

    These features combined with the compact size make the StageBug SB4 the perfect companion for orchestral artists, blue grass players and pop string quartets that need to turn it up when in concert.
