AMS NEVE 1081

The Indispensable Tool for all Instruments and Vocals

Designed in 1972, the 1081 was originally conceived as a combined mic/line preamp and equaliser section for the Neve® modular consoles. It quickly became one of the best-loved mic preamps of all time. In practice, over three decades of engineers have found the 1081 an indispensable tool for recording and mixing drums, bass and percussion.

Preamp Specification

• Microphone Input: Input impedance 300 or 1200 Ohms, gain +80db to +20dB in 5dB steps. Input is transformer balanced and earth free.
• Line Input: Input impedance 10k Ohms bridging, gain +20 to -15dB in 5dB steps. Input is transformer balanced and earth free.
• Outputs: Max >+26dBu into 600 Ohms. Zout 75 Ohms ±5% @ 1kHz, balanced and earth-free An unbalanced output 8dB below the level of the balanced output is also provided.
• Distortion: Not more than 0.07% for +20dBm output from 50Hz to 15kHz (80kHz bandwidth)
• Frequency Response: ±0.5dB from 20Hz to 20kHz. -3dB at 7Hz and 35kHz
• Noise: Output noise better than -42dBm from Zin 1200 Ohms and -80dB input, giving an equivalent noise of -125dBm referred to 600 Ohms input impedance fed from 100 Ohms Output noise better than – 80dBm at all line input levels (22Hz to 22kHz bandwidth)
