　　Variable Load Active DI with Piezo Optimized Input

　　The PZ-DI? is an active direct box that has been designed for acoustic and orchestral instruments, with a variable load that allows you to set the optimal input impedance for your pickups for more natural-sounding results.

　　Optimized for orchestral instruments on a live stage

　　Adjustable load for piezo and magnetic pickups

　　Variable low-cut filter to control low frequency resonance

　　Powered by 48V phantom, no batteries required

　　Piezo problem solver

　　The 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.
