Milford, NH, January 21, 2013 –Earthworks will introduce its first 500 Series module, the 521 ZDT at the 2013 NAMM show this week in Anaheim, CA (Booth 6882).
Based on the ZDT Preamp technology designed by David Blackmer, the 521 ZDT brings the exacting standards of the Zero Distortion Technology preamplifiers to the convenient 500 series format, providing a “wire with gain” option to the 500 series rack.
The solid state ZDT 521 features switchable phantom power, polarity invert, and peak amplitude clip detection, just as in the original 1021 single channel ZDT Preamp. The transformerless output stage of 521 ZDT will easily drive long cable runs without loss of quality, making it ideal for remote recordings. Transparent gain is switchable from 5dB to 60dB in 5dB steps.
The Earthworks mic amp topology provides outstanding common mode rejection, excellent overload margin and an incredibly low noise floor, combined with the ultra wide bandwidth of the ZDT Preamps (1Hz to 200kHz +0.5dB) and distortion of less than 1 part per million (0.0001%). This exceptional level of performance is maintained over an extensive range of impedances applied to the input, making the 521 ZDT suitable for practically any microphone – ribbon, dynamic or condenser.
