Radial PZ-DI Orchestral Instrument DI

The Radial PZ-DI Orchestral Instrument DI is a high-performance, specialized active direct box meticulously designed to accommodate the nuanced needs of acoustic and orchestral instruments. With its selectable input impedance, the PZ-DI can seamlessly work with both magnetic pickups and piezo transducers, ensuring optimal performance. Its variable low-cut filter is an essential tool for fine-tuning your instrument's sound, making this DI a versatile addition to any musician's toolkit.

The PZ-DI addresses the critical issue of impedance matching, offering a variable load selector switch. This feature allows musicians to precisely set the input impedance of the DI box. The 1 meg ohm position replicates the classic impedance found on most active DI boxes, while the 220k ohm setting warms up magnetic pickups, emulating the experience of plugging directly into an amplifier. For piezo transducers, the PZ-DI provides an ultra-high 10 meg ohm setting, which is specifically designed to counteract the harsh or squawky tones often produced when using a lower impedance input.

The PZ-DI is equipped with a fully-variable low-cut filter that significantly enhances live performance by removing unwanted resonance and preventing feedback. This filter's roll-off point can be adjusted to match the specific frequency response of your instrument, making it suitable for everything from acoustic basses to violins or banjos. Additionally, a switchable high-cut filter is included to soften the harshness of battery-powered preamps in acoustic guitars, resulting in a smoother tone. Powered by 48V phantom power, the PZ-DI eliminates the need for batteries, ensuring reliability and ease of use during performances.
