Radial PZ-Pre

Acoustic Instrumental Preamp

The PZ-Pre is a powerful acoustic instrument preamplifier with a powerful EQ and feedback control section and loads of connectivity options giving you complete control over your rig.

• Two channels to switch or blend instruments

• Notch & resonance filters eliminate feedback

• Pre & Post Radial DI outputs for PA and monitors

• Power booster and mute for more control on stage

Powerful Control in a Box
The Radial PZ-Pre™ is a powerful acoustic instrument preamplifier. The magic lies in the combination of high performance 100% discrete class-A PZB piezo boosters, an ultra-quiet preamp circuit that will adapt to any pickup system and a host of connectivity options that will put you in total control. The PZ-Pre is equipped with two inputs for quick instrument changes on stage, or, for blending two pickups together. Powerful semi-parametric EQ and feedback eliminating controls allow the user to fine-tune their sound while eliminating troublesome frequencies. Offering both pre and post EQ direct box outputs, the PZ-Pre can be used send a dry signal to the house and performer tailored sound to monitors.

FEATURES

Boost
Gives you up to 8dB of added gain for solos. Works with boost footswitch.

3 Band EQ
With bass, semi-parametric mid range and high frequency controls.

Notch
Sets the center frequency for the notch filter. Used to eliminate feedback.

Level 1 & 2
Sets the input volume level on each channel.

Phase
Reverse used to correct the phase relationship of the instrument output to reduce on stage feedback.

Footswitch Assign
Used to set the Boost footswitch  for boost, effects loop or both.

Notch-Q
Selects normal or extra deep notch. Works with notch frequency control.

Lo-Cut
3 position filter reduces low frequency rumble and resonance that can cause feedback or muddy the sound.

Mute
Footswitch turns off all outputs except the tuner out. Used for quiet on-stage tuning.

Boost
Footswitch activates booster or effects-loop. Works with Boost Assign footswitch.

Toggle
Footswitch lets you select between ch-1 and ch-2. LEDs indicate active input.

PZB-2
Recessed switch turns on class-A booster and increases impedance to 10meg Ohms for piezo equipped instruments.

Loop Send / Return
Inserts effects into the signal path. Activated with boost footswitch.

Pre-EQ Output
Balanced direct box XLR output used to send dry signal (without EQ) to PA system.

Lift
Disconnects pin-1 ground at the XLR output to help eliminate hum & buzz caused by ground loops.

180°
Recessed switch reverses pins 2 and 3 at the XLR output. Used to help eliminate feedback.

Post-EQ Output
Balanced direct box XLR output used to send wet signal (with EQ) to the PA system or monitors.

Tuner
Always on buffered output is used with the mute footswitch for quiet on-stage tuning.

15VDC Power Supply
Delivers more head-room than a typical 9V supply for added clarity and dynamics.

Class-A Circuitry
Ensures optimal signal flow and the most natural tone.

Potentiometers
Double up solder points for greater durability. Steel casing with steel shaft and retention nut will not bend when under stress.

Switches
Extra Durable switches with metal outer casing are rated at over 20,000 cycles.

Connectors
Glass filled nylon housing is tougher than steel and provides isolation for reduced noise. Nickel-silver contacts will not tarnish.
