PZ-DI™ Specifications

The Radial PZ-DI is an active direct box that has been optimized for use with acoustic instruments. It boasts an 'always on' high-pass filter that delivers an exceptionally linear response from 40Hz to 20kHz with less than 0.05% distortion when used with instrument level sources. And with noise levels -125dB below the normal operating level, PZ-DI rivals the very best studio preamps made today. The innovative ground lifting scheme enables pin-1 audio ground to be lifted without cutting off 48V phantom, thus enabling the J48 to be used without reverting to batteries. The Radial PZ-DI may well be the most versatile 48 volt phantom powered direct box made today.
