Description

The PZ-Pro gives each of its two channels its own semi-parametric equalizer, input level and filter section, with a variable notch or high-pass filter for reducing feedback. Channel 1 and channel 2 each have a piezo booster for smoothing the response of piezo-equipped instruments. Magnetic pickups, instruments with on-board preamps and piezo transducers can all be connected.

Channel 2 adds an XLR microphone input with 48V phantom power, so a dynamic, condenser, clip-on instrument or vocal microphone can be blended with a pickup or run through guitar pedals. An assignable effects loop with a wet/dry control can be placed on channel A, channel B or both, and can be switched by footswitch or left always on. Three footswitches select the channel, toggle the clean boost and effects loop, and mute the signal for silent tuning.

Balanced XLR direct outputs send the signal to a PA system or recording interface, with both pre-EQ and post-EQ outputs available. A power supply is included.
