The Crescendo is the first microphone preamplifier which operates with an internal operating voltage of 120V. Making it absolutely unique, because with the 120V Technology it is nearly impossible to overdrive this preamplifier. The Crescendo excels with absolute signal fidelity and clarity. Rediscover your microphones, they have never been amplified like this.

The Crescendo features a fully balanced signal flow. The input stage uses 10 pairs of matched PNP Transistors (Differential Input Transistors) for extremely low noise and a very high common mode rejection. Each of the eight input stages has six 5th generation 120V SPL SUPRA Operation Amplifiers. The transformerless design of the input/output stages guarantees highly linear amplifying. The output stages operate as current amplifier and therefore provide Class-A operation with more than 6mA quiescent current.
