SPL Crescendo Duo Microphone Preamplifier

The SPL Crescendo Duo is a Dual-Channel Microphone Preamplifier with 120V technology, providing exemplary reproduction from the very best microphones.

SPL Crescendo Duo Microphone Preamplifier

SPL Crescendo Duo combines the precise sound that German Rundfunk-Technik is famous for with the innovative SPL 120V technology. The internal operating voltage of 120 volts allows Crescendo microphone preamplifiers to break completely new ground. This results in microphone preamps that sound detail-rich, vivid and equally honest.

Crescendo duo lets microphones shine in a whole new light – because they have never been amplified like this before.

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 of the SPL Crescendo Duo 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 SPL 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.

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.
