Radial Engineering PZ-Deluxe Overview

The PZ-Deluxe Acoustic Preamp from Radial Engineering is a studio-quality instrument preamp that jam-packs a full array of features into a compact pedal for live stage and other uses.

The PZ-Deluxe begins with a low noise front end that is capable of quality dynamics to adapt to all instruments including acoustic guitar, upright bass, mandolin, and violin irrespective of the type of pickup system that is being used. For piezo transducers, a special PZB gain stage may be engaged that increases the input impedance to 10 MΩ for eliminating squawk and explosive peaks. This eliminates the need for a separate preamp and additional holes in your guitar.

The control panel is appointed with an input gain, 3-band semi-parametric EQ with variable mid-frequency, 3-position low frequency resonance filter, and 180° polarity reverse switches to eliminate acoustic hot spots that cause runaway resonant feedback. A guitar level output delivers the sound to the artist's stage amp, while the built-in Radial direct box feeds the PA system. This balanced low impedance output enables this unit to drive long cable runs of over 300’ (100m) without noise. A separate tuner output enables quiet, on-stage adjustments by depressing the mute switch. For solos, a variable power booster with set-and-forget level control lets you punch through the mix when needed.

The PZ-Deluxe Acoustic Preamp is compact for ease of transportation, made tough to handle the road, plug-and-play, easy-to-use, and delivers impressive studio quality audio.
