The SPL Crescendo Duo V2 Preamp combines the precise sound that German Rundfunk-Technik is famous for with the innovative SPL 120V technology. Crescendo Duo lets microphones shine in a whole new light – because they have never been amplified like this before.

The internal operating voltage of 120 volts allows Crescendo microphone preamplifiers to break completely new ground. This results in microphone preamps that create a detail-rich, vivid and equally honest sound image.

The Undistortable
Thanks to the SPL 120V technology, it is almost impossible to overdrive this microphone preamplifier. Crescendo duo is a dual-channel microphone preamplifier with 120V technology. Both channels feature the same range of functions. Besides phantom power (48 V) for condenser microphones, polarity reversal, a high-pass filter and a PAD switch, they provide the possibility to adjust the VU meter to display very high levels – so they leave nothing to be desired. The gain can be adjusted comfortably and precisely via a 12-step switch. With the switchable output control, the output level of the Crescendo duo can be perfectly adapted to following AD converters. Two outputs per channel allow the signal to be sent to two different devices in parallel. In addition to the extensive feature set and the outstanding technical characteristics, Crescendo duo convinces with a sonic authenticity that is second to none.

Looks great, feels great – and lasts for a lifetime
The Crescendo duo v2 has a 4 mm thick, black anodized aluminum front panel and aluminum knobs milled from solid. The housing is made of high-quality steel and is powder-coated in elegant black.

Sounds Great
With all SPL devices we develop not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.
