The PZ-DI Orchestral Instrument DI from Radial Engineering is a unique direct box that is specifically designed for acoustic and orchestral instruments. It lets you properly match the input impedance to the source to optimize the frequency response, dynamics and feel so that no matter what type of pickup you employ, you will enjoy smoother, more musically pleasing results.

The design begins with a 3-position load adjustment switch. The 1MΩ position delivers the classic impedance found on most active DI boxes. The 220kΩ setting warms up the tone of a magnetic pickup to give you the feel and tone as if connected to a tube amplifier. The ultra-high 10MΩ impedance is used to compensate for the harsh, squawky tone that usually plagues piezo-equipped instruments. This is followed by a fully variable high-pass filter that lets you size the instrument by gently rolling off bass frequencies to eliminate unwanted resonance. You could for instance, retain the low frequencies on a cello or increase the cut-off point to better suit a violin. For active instruments such as acoustic guitars that incorporate a battery powered preamp, you can engage a low-pass filter to gently soften the hard edge for a smoother, more natural tone.

To maximize signal handling and reduce distortion, this unit incorporates an innovative DC to DC switching supply that converts the phantom power to deliver extra headroom. This provides ample dynamic range for acoustic instruments. Should an extra loud source such as an active bass or digital keyboard be encountered, simply activate the -15 dB pad to satisfy the situation. It also includes a 180° polarity reverse switch to tame hot spots on stage that can cause feedback and a ground lift switch to help eliminate hum and buzz caused by ground loops.

It can instantly adapt to all types of pickups so that you can enjoy the full-frequency response and dynamics of an orchestral string instrument, smooth-out the peaks of bluegrass fiddle, banjo or mandolin, split off a bass guitar without excessive loading, or naturally amplify an acoustic guitar without the usual tone-altering effects.

Optimized for orchestral instruments on a live stage
Adjustable load for piezo and magnetic pickups
Variable low-cut filter to control bass resonance
48V phantom powered, does not require batteries
