Radial PZDI Active DI Direct Box for Acoustic Instruments

Optimized for piezo pickups, the PZDI direct box is perfect for DI'ing acoustic instruments. Engage the -15dB pad for louder sources like active basses.

The Radial PZ-DI has a variable load selector switch that allows you to set the input impedance of the direct box, so you can optimize the performance with your instrument's pickups. The 1 meg ohm position delivers the classic impedance found on most active DI boxes, while the 220k ohm setting warms up the tone of magnetic pickups to provide the feel and tone as if your instrument were connected directly to an amplifier. The third setting is an ultra-high 10 meg ohm impedance that is specifically designed for piezo transducers, helping compensate for the harsh or squawky tone that can occur when a piezo is connected to a lower impedance input.

Variable filter to suit any instrument

To remove unwanted resonance on stage and prevent feedback, the PZ-DI is equipped with a fully-variable low-cut filter that gently rolls off low frequencies. The roll-off point of this filter can be raised or lowered to match the frequency response of your instrument, with a lower point for acoustic bass and a higher setting for violin or banjo. A switchable high-cut filter is also included, which is useful on instruments such as acoustic guitars that incorporate a battery-powered preamp, softening any harshness or high frequency edge for a smoother tone
