The ZDT Zero Distortion Preamplifier™ series is based on discrete circuitry designed by David Blackmer, establishing a new standard of sonic excellence in electronics. This exacting new standard provides frequency response from 1Hz to 200kHz +0.5dB, a rise time of 0.27 microseconds and distortion of less than 1 part per million (0.0001%), eliminating all possibility of sonic degradation. These preamps are so fast, so clean and so transparent that you don’t even know they are there. It is like plugging your microphone into a “piece of wire with gain”. You will hear clarity and detail with the ZDT preamps that is not available in any other preamp at any price.


Zero Distortion – less than one part per million
High output level +30dBu
Very low output impedance will drive long lines without interference or signal loss
True 48 volt phantom, polarity reverse & clip indicator
Separate XLR & 1/4” Phone (t-r-s) outputs, each with its own gain/level controls
1/4” phone connector output will drive balanced or unbalanced inputs
Full differential (balanced) from XLR in to XLR out – no internal conversion to single-ended
All discrete components; Class A amplification (no ICs in the signal path)
Greater transparency with minimum signal path and minimum features
