Earthworks 1022 - Two Channel Preamp - 1U

Earthworks 1022

If you need the purest signal path possible then the ZDT preamps have been specifically designed to meet your needs. Supremely low distortion, a ruler flat response and rapid transient response add up to a neutral mic pre of Earthworks calibre.

Features

• 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
