Radial PZ-DI Orchestral Instrument DI

Radial PZ-DI – Active DI Box for Piezo and Acoustic Instruments

The Radial PZ-DI is a high-performance active DI box optimized for acoustic and orchestral instruments. With selectable input impedance and a variable low-cut filter, it can be adapted for both piezo elements and magnetic pickups, providing improved tone and reduced resonance during live performances and recording.

The PZ-DI is powered by 48V phantom power and requires no batteries.
