Breathe New Life Into Your Mix
Based on the ZDT Preamp technology designed by David Blackmer, the 1 RU space 521 ZDT Single-Channel Mic Preamplifier from Earthworks brings the exacting standards of the Zero Distortion Technology preamplifiers to the convenient 500 series format.
The solid-state 521 ZDT Preamplifier features switchable phantom power, polarity invert, and peak amplitude clip detection. The transformerless output stage of the 521 ZDT preamplifier can easily drive long cable runs without loss of quality, making it suitable for remote recordings. Transparent gain is switchable from 5 to 60 dB in 5 dB steps.
The Earthworks microphone preamplifier topology provides strong common mode rejection, a high overload margin, and a low noise floor, combined with the wide bandwidth of the ZDT preamplifiers (1 Hz to 200 kHz +0.5 dB), and distortion of less than one part per million (0.0001%). This level of performance is maintained over an extensive range of impedances applied to the input, making the 521 ZDT preamplifier suitable for practically any microphone—ribbon, dynamic, or condenser.
