The PZ-Deluxe begins 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. For piezo transducers a special PZB gain stage may be engaged that increases the input impedance to 10 meg-Ohms to eliminate squawk and explosive peaks that are common with other systems. This eliminates the need for a separate preamp - which is of particular importance for those that do not want to cut a hole into their vintage guitar. The control panel is well appointed with input gain 3-band semi-parametric EQ with variable mid-frequency three position low frequency resonance filter and 180 DEGREE polarity reverse switches to eliminate acoustic hot spots that cause runaway resonant feedback. A guitar level output delivers the sound to the artist s stage amp while the built-in Radial direct box feeds the PA system. This balanced low impedance output enables the PZ-Deluxe to drive long cable runs of over 100 meters (300 feet) without noise. A separate tuner output enables quiet on-stage adjustments by depressing the mute switch. And for solos a variable power booster with set & forget level control lets you punch through the mix when needed. The Radial PZ-Deluxe is compact for easy transportation made tough to handle the road plug & play easy to use and delivers exceptional studio quality audio.
