Earthworks 1024 ZDT Zero Distortion 4 Channel Mic Preamplifier
4 Channel Low noise Zero Distortion Mic Pre
Earthworks ZDT preamps are like wire with gain. their frequency response is flat and wideband. +/- 0.1db from 2Hz to 100kHz. the 1dB down points are below .5Hz and beyound 500kHz. Across the "audio band" the ZDT preamp is effectively perfect. The total of all forms of distortion is so low as to be unmeasurable by normal equipment. Under 1ppm (0.0001%) for the stepped gain output and under 0.001% for the variable output.
Earthworks ZDT preamps are the quietest mic preamps currently available on the market. This is particularly evident when high gain is used such as for classical music. Earthworks preamps are also perfect for ribbon mics, especially considering its high input impedance of 100 kOhms.
Earthworks ZDT preamps are simply perfect.
