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.

The Undistortable

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.

48 V

The phantom power required for the use of condenser microphones is activated with the 48V switch.

VU -10

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.

Ø

Turn the polarity of a microphone signal 180° by activating the polarity reversal switch.

HP

A high-pass filter with 6 dB per octave reduces subsonic noise below 120 Hz.

Mic Gain

The gain is adjusted by a 12-step switch. The pre-amplification ranges from +18 dB to +70 dB.

Output

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.  

Pad

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.

"Its sound has an extremely noble, gentle character, which lends depth and transparency to a recording. Especially in genres like jazz and classical music the Crescendo duo should be very popular, because it transmits the dynamics of a performance very well and offers so much headroom that distortion is not an issue at all.

The 120V Technology

What exactly is that?

And what does it do?

Good questions need good answers. And that’s what the 120V video gives you.

VOLTAiR is that good

In the lab, we pitted Phonitor xe against the best audio measurement system and found that Audio Precision could not measure VOLTAiR technology.
