SPL Audio Crescendo duo V2

SPL’s Crescendo Duo Receives an Upgrade

The SPL Crescendo Duo is a new version of the company’s preamp technology, featuring a new design, improved enclosure, and additional amplification stages. It features transparent, high-headroom preamp technology in a 2-channel package, with an internal working voltage of 120 volts and a potential operating voltage of ±60 volts. This allows for flawless amplification of fast transients, fine details, and the entire frequency range with low distortion. The SPL Crescendo Duo is an excellent choice for studio mic pres.

What’s aboard

Each Crescendo Duo preamp has +48 phantom power, input and output gain, a VU meter, polarity reversal, a 20dB pad, and a -10 reduction control for the VU meter display. The 12-step mic gain knob has a range of 18dB to 70dB, enough power for even low-output passive ribbon microphones. Use a Pad to bring high-level input signals down within the acceptable range (-2dB to 50dB).

What is below the hood

The Crescendo Duo is full of technological innovation and high-quality components. The differential amplifiers in the input stage are constructed from carefully matched transistor pairs that are housed in a customized enclosure. The transistor matching, together with thermal coupling, ensures strong common-mode rejection and extremely low total harmonic distortion. Meticulous transistor and resistor selection has a significant influence on the sound and adds to its transparency. The Crescendo Duo’s ideal components were picked as part of continual critical listening sessions, and the results speak for themselves.

Cutting-edge equipment for professional studios

SPL — Sound Performance Lab — is a German pro audio firm that has been on the cutting edge for the past 30 years. SPL hardware may be found in top studios and mastering facilities all around the globe, including the acclaimed Transient Designer, TwinTube, and Vitaliser MK2-T, as well as professional mastering tools like Passeq. SPL has released another innovative product. The Crescendo Duo sets a new standard for high-end mic preamps with its remarkable ability to handle any source without perceptible distortion.
