Radial PZ-Deluxe

Acoustic Instrumental Preamp

The PZ-Deluxe is a studio quality instrument preamp in a compact pedal for live stage use, with tone-shaping EQ controls and built-in boost & mute footswitches.

• Acoustic preamp for all types of pickups and transducers

• Low-cut filter and 180° polarity reverse to eliminate feedback

• Radial direct box output to feed the PA

• Power booster and mute for more control on stage

Control your tone on stage
The PZ-Deluxe is an instrument preamp with a low noise front end that is capable of exceptional dynamics to adapt to all instruments including acoustic guitar, upright bass, mandolin and violin no matter what type of pickup system is being used. Powerful EQ controls allow you to shape your tone through the PA and a stage amp, with a low cut filter and 180° polarity reverse switches to help eliminate feedback on stage. A special PZB gain stage can be activated for use with instruments that have piezo transducers, increasing the input impedance to 10 meg ohms to eliminate the squawk and harshness that are sometimes associated with those pickup systems. The PZ-Deluxe also features a high quality Radial DI to provide a balanced output that can drive cables of over 100 meters (300ft) without noise into the PA system, and built-in mute and boost footswitches give you instant control for solos, instrument changeovers, or silent tune-ups on stage.

FEATURES

EQ
Semi-parametric equalizer with separate high and low shelving with a variable mid-frequency for optimal tone shaping.

Level
Fully adjustable control sets the PZ-Deluxe overall volume level on both the stage amp and DI outputs.

Mute
shuts off the outputs going to the stage amp and low-Z direct out to allow quiet on-stage tuning.

Lift
Lifts pin-1 on the XLR output to help eliminate hum and buzz caused by ground loops. 

180°
Phase inverter reverses the polarity of the signal going to the stage amp to help eliminate acoustic hot-spots on stage that can cause feedback.

HPF
3 position switch cuts low frequencies to reduce resonance which can often cause feedback on stage.

Boost
Footswitch lets you increase the level for solos when needed. Fully variable ‘set & forget’ gain adjustment on side panel.
