USER GUIDE

PZ-Pro™

Radial Engineering Ltd.

OVERVIEW

The PZ-Pro may appear complicated due to the many available features

and conguration options, but it can be simplied by breaking it down into

four main sections:

INPUTS AND EQ

The PZ-Pro has two input channels, so you can have two separate sound

sources connected at the same time. Two 1/4" input jacks provide con-

nection to any instrument source, and the PZ Boost switches allow you

to optimize each input for use with piezo transducers. Channel B also

features a microphone input, so you can blend a clip on microphone with

your instrument pickups, or even connect a vocal mic.

EFX LOOP AND BOOST

Two additional features on the PZ-Pro are the EFX Loop and clean Boost,

both of which can be congured to match your playing style and your

specic setup. The EFX Loop allows you to connect your guitar e󰀨ects

pedals directly to the PZ-Pro, so you can share them across both inputs,

or use them on just one source while leaving the other una󰀨ected. A wet/

dry control allows you to blend in how much of the pedal e󰀨ects are added

to your sound. The Boost is a class-A signal booster with up to +15 dB of

clean gain that allows you to cut through the mix when soloing.

FOOTSWITCH CONTROL

The PZ-Pro also has three useful footswitches for real-time performance

control on a live stage. The Input footswitch toggles between the two inputs,

making instrument changeovers on stage silent and seamless. The EFX/

Loop footswitch is assignable, and can be selected to turn the EFX Loop

on and o󰀨, activate the clean Boost, or control both simultaneously. Lastly,

the Mute footswitch provides an easy way to cut output signals from the

PZ-Pro so only the Tuner out is active, allowing for quiet on stage tuning

at a moment's notice.

OUTPUTS

Two balanced DI outputs are provided on the PZ-Pro over XLR connec-

tors to feed PA systems up to 300' away without signal degradation or

noise. Pre EQ and Post EQ options are provided, and both can be used

simultaneously. This gives you the ability to send a direct feed of your

instruments to the main PA system, while taking the Post EQ shaped sound

to your monitor system for in-ears or stage wedges. In addition to the XLR

outputs, the PZ-Pro also has a 1/4" amp out to feed a stage amplier, and

a bu󰀨ered always-on output to feed a tuner pedal.

MAKING CONNECTIONS - THE 1/4" INSTRUMENT INPUTS

The PZ-Pro features two 1/4" inputs on the rear panel,

allowing you to connect two instruments and toggle

between them or blend both together simultaneously.

Using these inputs you can switch between two guitars

with di󰀨erent tunings, blend together multiple pickup types

on a single instrument, or switch between other acoustic

instruments such as mandolin or banjo.

Each input is equipped with a corresponding Level

control, allowing you to adjust the relative volume of

each instrument and compensate for any di󰀨erences in

output levels from your pickups. Start with both Level

controls at 12 o'clock - this is the unity gain setting on the

PZ-Pro. When turned up fully clockwise, the Level

controls provide +20dB of gain to your input signals.

When using just a single instrument with the PZ-Pro, plugging into input

A allows you to use both channels of the PZ-Pro as if you were playing

through a two-channel amplier. This is due to the fact that Input A

automatically feeds into Input B when nothing is connected to the Input B

1/4" jack (and when the Mic On switch is disengaged). This gives you the

ability to use both of the input channels with a single instrument, so you

can use the Toggle Footswitch to select between the two Level, EQ and

Filter settings when switching between verse and chorus, for example.

USING THE PZ BOOST SWITCHES

Each of the 1/4" Inputs on the PZ-Pro is also equipped

with a special PZ Boost circuit, which can be activated

by engaging either one of the recessed switches on

the right side of the unit. These switches raise the

input impedance of each of the 1/4" inputs from 220k

Ohms to 10Meg Ohms, while simultaneously engaging

a class-A signal booster to bring the level up by an

additional +10dB.

This PZ Boost helps broaden the frequency response and smooth

out the transient peaks of instruments that employ piezo transducers.

Engaging the PZ booster won't harm typical pickup systems, so feel free

to experiment and try it out on di󰀨erent input sources to see if you like

the results.

CONNECTING A MICROPHONE

The PZ-Pro includes a locking female XLR jack for

connecting a microphone to the Input of channel

B. When activated, the microphone input overrides

the instrument input for channel B - this is done

by activating the Mic On switch next to the XLR

connection. You can use this input for clip-on

instrument mics, wireless microphones, and even

vocal mics! The Mic Input,

48V and Mic On

For dynamic microphones that don't require additional power, simply

plug and play. When connecting condenser microphones that require

phantom power, rst connect your mic, then hit the Mute Footswitch to

prevent any pops through the audio system, and nally activate the 48V

switch on the rear panel of the PZ-Pro to power your microphone. The

channel B Level control provides up to +55dB of gain when the Mic On

switch is active.

CONNECTING INSTRUMENTS WIRED WITH

TWO PICKUP SYSTEMS

Input B on the PZ-Pro is specially equipped to accommodate instruments

with two pickup systems wired to a single 1/4" TRS (Tip, Ring, Sleeve)

output. This allows you to feed a separate pickup system to each

channel of the PZ-Pro using a single cable. Simply use a 1/4" TRS cable

as shown in the diagram below to connect to Input B of the PZ-Pro, while

leaving nothing connected to Input A. The Tip conductor of the cable will

feed channel B, while the ring will feed channel A, giving you the ability

to switch between the two pickups or blend them together with the A+B

switch.

BLENDING BOTH INPUTS TOGETHER

While the PZ-Pro makes it easy to toggle between

two inputs at the press of a footswitch, you may also

wish to blend both input sources together, allowing

you to combine the warmth and low end from a

microphone with the brightness and clarity from

your pickup system. To combine both input signals,

press the A+B switch on the rear panel of the PZ-

Pro. Once this switch is engaged the A and B LEDs

will both illuminate and the Toggle Footswitch will no

longer have any e󰀨ect as both inputs will be active

at all times.

Aside from the Toggle Footswitch, when blending both inputs together

with the A+B switch the remaining PZ-Pro features will continue to

function normally: The EQ and Filter sections still allow you to tailor the

sound of each individual input before they are blended, and the FX Loop

and Boost controls can be assigned to a󰀨ect only Input A, Input B, or

The A+B switch

The 180 switch

With the A+B switch engaged, the PZ-Pro can blend together

two sources, such as a set of pickups and a microphone

both.

When summing two di󰀨erent signals from the same

sound source, it is common for some frequency

cancellation to occur as a result from each signal

arriving at the PZ-Pro at slightly di󰀨erent times. The

Input B 180 switch helps correct for this by reversing

the polarity on Input B, a󰀨ecting both the XLR Mic

Input and the 1/4" Input on this channel.

There is no right or wrong setting for the 180 switch, so try it in both

the o󰀨 and on positions while playing your instrument to see which one

sounds best to your ears. If you have a hard time telling the di󰀨erence,

try playing the lowest note on your instrument, as frequency cancellation

is easiest to hear in the lower register.
