Radial Engineering Ltd. is pleased to announce the StageBug SB-4 Piezo, a direct box specifically developed to solve the problems associated with amplifying acoustic instruments when using piezo-electric transducers.

The StageBug SB-4 begins with a ¼" input to connect the instrument's piezo transducer output.* This 10 meg-ohm input is ten times higher than a traditional DI. The higher impedance smoothes out the peaks and squawk that is common to most piezo systems while broadening the frequency response for a more natural and pleasing sound. A thru-put connector may be used to feed a personal stage amp or a tuner.* A traditional XLR out is used to feed the PA and it is equipped with a 180° polarity reverse switch. This helps tame hot spots on stage by electronically moving acoustic peaks and valleys that naturally occur when the PA system combines with the room acoustics. Reversing the phase eliminates feedback without resorting to excessive equalization or notch filtering which only serves to degrade the natural tone of the instrument. To further reduce feedback, a low-pass filter eliminates excessive bass that can cause the instrument to resonate. This also helps clean up the mix when combining multiple instruments.

All combined, the Radial SB-4 solves the problems associated with piezos while delivering great sound to the audience.

The SB-4 begins shipping in March 2013.
