Crescendo duo
Two-Channel Microphone Preamplifier with
120V Technology
The Crescendo duo 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.
Both input stages have six 5th generation 120V SPL SUPRA Operation Amplifiers
each.
The transformerless design of the input/output stages guarantees highly linear
amplifying.
The output stages operate as current amplifiers and therefore provide Class-A
operation with more than 6mA quiescent current.
