Radial PZ-Pro

2-Channel Acoustic Instrumental Preamp

Take complete control over your tone, EQ settings, and effects with the PZ-Pro, a two channel instrument preamp, DI and switcher. Each channel features a separate equalizer strip complete with a filter section to reduce feedback on stage. The second channel of the PZ-Pro also features a microphone input to allow any dynamic or condenser microphone to be used, including clip-on instrument mics. Three footswitches provide the ability to toggle between each input channel, activate a built-in booster and an effects loop, or mute the signal for silent tuning on stage.

• 2 channel acoustic instrument preamp with separate EQs

• Piezo input boosters available on both channels

• XLR input with available phantom power on channel 2

• Assignable FX loop with wet/dry control

Mission control for your acoustic setup
The PZ-Pro is designed for instrumentalists and performers who take a no-compromise approach when it comes to tone, both on stage and in the recording studio. Dual input channels allow you to switch between or blend together two sources, with full control over the sound of each input. Each channel has its own semi-parametric equalizer section and input level, along with individual filter controls to reduce feedback on stage. The second channel of the PZ-Pro also features a microphone input to allow any dynamic or condenser microphone to be used, including clip-on instrument mics or even vocal microphones. An FX Loop with a wet/dry knob provides the ability to blend in as much or as little pedal effects as desired, with a footswitch to bring them in and out of the signal chain at a moment's notice. Finally, once your tone is completely dialed-in, balanced XLR direct outs feed the PA system or a recording interface, with both Pre-EQ and Post-EQ outputs available.

Adaptable for any application
The PZ-Pro is highly configurable, so you can adapt it to meet the needs of your performance, instead of changing your performance to fit the limitations of your gear. Connect magnetic pickups, instruments with on-board preamps, or piezo transducers, and optimize the sound of each with powerful EQ controls and a variable notch or high-pass filter. Blend an instrument mic with your pickups, switch between two instruments, or connect a vocal microphone and feed it through your guitar pedals. The FX loop can be assigned to channel A, B, or both at once, and you can activate it with a footswitch or assign it to be always on, saving footswitch control for the variable clean boost function. With the PZ-Pro, you get the durability and performance Radial is known for, along with all the features you need to put on an unforgettable show.

FEATURES

Level
Sets the volume on each input channel. Unity gain is 12 o'clock.

3 Band EQ
Variable EQ for each input with bass, semi-parametric mid range, and high frequency boost/cut controls.

Filter
Three-position switch and variable control activates a notch filter for targeted frequency removal or a high-pass filter to remove excessive low end rumble.

FX Blend
Wet/Dry control allows you to mix the original 'dry' input sources with the 'wet' FX Loop.

FX Loop Assign
Selects whether guitar pedals in the FX Loop affect the signal on input A, input B, or Both.

Footswitch Assign
Used to set the Boost/FX Loop footswitch to activate the Boost, FX Loop, or both simultaneously.

Boost
Sets the amount of clean boost applied when the Boost circuit is active.

Toggle
Footswitch lets you select between input A and input B, with LEDs to indicate active input. This switch is bypassed when the rear panel switch is engaged.

Boost / FX Loop
Footswitch activates the built-in clean boost or the FX loop. Works in conjunction with the Footswitch Assign three-position switch.

Mute - Footswitch
Turns off all outputs except for the Tuner Out. Used for silent on-stage tuning or instrument changeovers.

Input-A
1/4" TS instrument input for channel A of the PZ-Pro.

Input-B
1/4" TS instrument input for channel B of the PZ-Pro. This input is deactivated when the MIC ON switch is engaged.

180°
Polarity reverse switch for input B helps to correct for phase issues when summing both inputs together. This switch also affects the microphone input on channel B.

A/B
Sums input A and input B together after their respective EQ sections. Engaging this switch activates both inputs simultaneously and disables the Toggle footswitch on the PZ-Pro.

48V
Activates phantom power at the Mic Input B for powering condenser microphones.

Mic On
Activates the XLR Mic Input B, disengaging the 1/4" instrument input on channel B.

Mic Input-B 
XLR input for connection to a microphone to feed channel B of the PZ-Pro. Compatible with both condenser and dynamic microphones.

Tuner Out
1/4" TS buffered output for connection to a tuner pedal. This output will always be active, even when the Mute footswitch is engaged on the PZ-Pro, allowing for tuning at any time.

Amp Out
1/4" TS instrument-level output to feed an on-stage amplifier. Amp out signals include all EQ settings, along with the FX loop and Boost functions.

FX Send & Receive
1/4" TS instrument jacks for connecting external effects pedals to the PZ-Pro. Activated by the Boost/FX Loop footswitch.

PRE EQ Output
Balanced XLR direct box output to feed a mic-level signal to the PA or a recording interface. Pre EQ Output is not affected by EQ settings or FX/Boost functions.

PRE EQ 180°
Reverses the polarity of the Pre EQ Output to help eliminate feedback on stage or correct for phase issues when summing the DI output with a mic'd up stage amplifier.

PRE EQ Lift
Disconnects pin-1 at the Pre EQ XLR Output to help eliminate hum and buzz from ground loops.

POST EQ Output
Balanced XLR direct box output to feed a mic-level signal to the PA or a recording interface. Post EQ Output is affected by the EQ and FX/Boost functions.

POST EQ 180°
Reverses the polarity of the Post EQ Output to help eliminate feedback on stage or correct for phase issues when summing the DI output with a mic'd up stage amplifier.

POST EQ Lift
Disconnects pin-1 at the Post EQ XLR Output to help eliminate hum and buzz from ground loops.

15VDC
Connection for Radial 15VDC/400mA power supply (included).

Cable Clamp
Prevents accidental power disconnection by locking down the cable for the PSU.
