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
All discrete components; Class A amplification (no ICs in the signal path)
Greater transparency with minimum signal path
The ZDT 1022 delivers on its promises in spades and sounds (or doesn’t sound, depending on your perspective) phenomenal.
The ZDT preamps are very transparent, like the preamps are not even in the chain, and let the mic do the work it is supposed to, and translates it beautifully.
Robert Root, RECORDING ENGINEER
It is about as transparent as anything I have heard. The sound is completely uncolored and noise is just about as low as it gets.

The Earthworks 521 ZDT is a stunning microphone preamplifier. A completely flat response across such a wide frequency range.
