The SPL Crescendo Duo Preamp offers a lot of technology and class in a two channel rack mount unit. Clean and accurate sound with loads of headroom and dynamic range, without noise or distortion, built-in splitters, and 80dB makes the Crescendo Duo an exciting Preamp.

The SPL Crescendo Duo Preamp 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.
