Dual-Channel Microphone Preamplifier in 120V-Technology
With the Crescendo duo, we are expanding our 120V microphone preamp portfolio with a dual-channel version of the Crescendo.
Crescendo duo convinces with the same outstanding sound and technical features as the flagship of the product range – the eight-channel Crescendo.
It is almost impossible to overdrive this microphone preamplifier. It shines with absolute signal fidelity and clarity and lets microphones appear in a whole new light – because they have never been amplified like this before.
The phantom power required for the use of condenser microphones is activated with the 48V switch.
In the Crescendo duo, high gains can be used to optimally drive subsequent AD converters. Should the VU meter therefore deflect too far, you can reduce the displayed level by 10 dB.
Turn the polarity of a microphone signal 180° by activating the polarity reversal switch.
A high-pass filter with 6 dB per octave reduces subsonic noise below 120 Hz.
The gain is adjusted by a 12-step switch. The pre-amplification ranges from +18 dB to +70 dB.
The switchable output control allows level adjustment to subsequent devices. The control range is +/- 10 dB. This results in a total gain of 80 dB.
For loud input signals (including line signals) the input sensitivity can be reduced by 20 dB.
Built-in Output Splitter
Both microphone preamps have dual outputs. The often needed splitter is therefore already built in. Record the microphone signal on a recording system and at the same time record it on a backup system.
