Description
Discover the Radial PZ-DI Orchestral Acoustic Direct Box, a versatile companion for musicians seeking to elevate their sound on stage or in the studio. Engineered to cater specifically to acoustic and orchestral instruments, this direct box ensures that your instrument's natural tone and dynamics shine through. Unlike traditional direct boxes, the 3-position load adjustment switch allows you to tailor the impedance for piezo and magnetic pickups, providing the perfect match to optimize frequency response and tonal character.
Whether you're playing a cello, acoustic guitar, or any other string instrument, the PZ-DI offers a suite of features to enhance your performance. The variable high-pass filter enables you to control bass resonance, while the low-pass filter gently warms the high end, ensuring a balanced sound across all frequencies. Additionally, the innovative DC to DC switching power supply harnesses phantom power to deliver extra headroom, maintaining the integrity of your instrument's sound even at high volumes.
For those moments when stage noise becomes an issue, the PZ-DI is equipped with a polarity reverse switch to combat feedback effectively. The ground lift switch further aids in eliminating hum and buzz caused by ground loops, ensuring a clean and pristine output. With its robust metal housing and thoughtful design, the Radial PZ-DI is a reliable partner for any musician looking to translate their instrument's voice accurately to the audience.
