SPL's Crescendo Duo Gets an Upgrade
Armed with a bold new look, a different and improved housing, and more steps of amplification, version two of the SPL Crescendo Duo packs the company's acclaimed transparent, high-headroom preamp technology into a convenient 2-channel format. If you're not familiar with the Crescendo series yet, let Sweetwater clue you in. These preamps have an internal operating voltage of 120 volts, which makes it almost impossible to overdrive. Thanks to this proprietary technology and high-voltage SUPRA op-amps, the Crescendo Duo has a potential internal operating voltage of ±60 volts, enabling it to effortlessly and flawlessly amplify even the fastest transients, the finest details, and the complete frequency range, with stunning clarity and incredibly low distortion. If you've been looking for a new mic pre to add to your studio, you can't go wrong with the SPL Crescendo Duo.

What's onboard
Each of the Crescendo Duo's preamps is equipped with +48 phantom power, input gain, output gain, VU meter, polarity reversal a 20dB pad, and a -10 reduction switch for the VU meter display. The 12-step mic gain knob controls a range from 18dB to 70dB, providing plenty of juice for even your low-output passive ribbon mics. Engage a Pad to knock high-level input signals down into the comfort zone (-2dB to 50dB).
What's under the hood
The Crescendo Duo is packed full of technical innovation and quality components. The differential amplifiers in the input stage are built with precisely matched transistor pairs, grouped in a special housing. The transistor matching, combined with thermal coupling, guarantees high common-mode rejection and exceptionally low total harmonic distortion. Meticulous transistor and resistor selection has a huge impact on the sound and contributes to its transparency. The perfect components for the Crescendo Duo were chosen in the context of ongoing critical listening sessions, and the results tell all.
