NEVE - 1081 - Classic Mic Preamp & Equalizer

NEVE - 1081 - Classic Mic Preamp & Equalizer

The 1081 channel amplifier was first produced in 1972 and was used to provide the mic/line-amp and EQ sections in Neve consoles such as the 8048. A look through the credits on today’s top selling CDs will reveal that these vintage consoles are still widely used to great effect and that the 1081 module has become a hugely popular design classic. AMS Neve is therefore pleased to announce that production of the 1081 module has been resumed, using the original components and construction methods.
To quote the 1972 sales leaflet: “This versatile instrument not only provides wide range control of sensitivity and effective high and low pass filters designed to separate unwanted signal outside the passband, but also gives the operator a flexible tool with which he can create new sounds and control any part of the audio spectrum.

The curves and slopes have been carefully tailored to be musically related enabling the operator to exercise maximum technical and artistic skill. The unit is totally enclosed and fully screened with covers on both sides providing easy access. High grade conservatively rated components are used throughout with all active circuitry on plug-in printed circuit cards giving high reliability and minimum down time.”
