8-Channel Microphone Preamplifier in 120V-Technology
The Crescendo is the first microphone preamplifier that works with an internal operating voltage of 120V and breaks new ground.
Imagine a microphone preamplifier with such a wide dynamic range and high overload resistance that the entire dynamic range of the microphone can be recorded without any limitations.
Imagine that the preamplification electronics themselves have no effect on the sound and you rediscover the sound of your microphones. With absolute signal fidelity and clarity.
Inputs 1 – 8
The input differential amplifiers are constructed with pairs of transistors, each of which is combined in a housing. Precise matching of the transistors and thermal coupling ensure high common-mode rejection and extremely low THD values.
The choice of transistors and resistors has a decisive influence on the sound. In countless listening sessions the optimal components for Crescendo were selected – the effort was worth it!
Outputs 1 – 8
Our 120V SUPRA operational amplifiers work as current amplifiers, which also offer pure class A operation with over 6mA quiescent current. We largely dispense with coupling capacitors in order to avoid their sonic disadvantages (diffuse, sloping, loss of dynamics). In order to eliminate DC voltage components nevertheless, active servo circuits are used.
Alternate DB25 Output
For fast cabling to multi-channel converters, Crescendo offers DB25 connection.
