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.
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 is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps.
The highest possible audio quality requires the highest possible audio operating voltage.
The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers.
This high voltage would destroy conventional components and operational amplifiers.
By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.
The mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.
The idea for SPL 120V technology and the SUPRA operational amplifier based on this technology were developed in the 1990s by SPL founder and chief developer Wolfgang Neumann.
With the goal of building the best mastering console ever, this basic technological philosophy then took shape for the first time – thus the SPL MMC1 Mastering Console for Galaxy Studios saw the light of day in 2000.
The outstanding sonic and technical features quickly got around in the scene – so further orders were not long in coming.
Besides the MMC 1, another legendary product with 120V technology was created with the PQ, the “King of Parametric Equalizers”.
Since that time, 120V technology has been the foundation for all SPL premium products. Meanwhile, not only for mastering applications, but also for the, studio or hifi use.
What exactly is that?
And what does it do?
Good questions need good answers.
And that’s what the 120V technology video gives you.
In the lab, we pitted Phonitor xe against the best audio measurement system and found that Audio Precision could not measure VOLTAiR technology.
