PRE-22 Dual Mic Preamp
The PRE-22 microphone dual preamp is inspired by the classic Harrison MR-4 console (1980), offering exceptional transparency, clarity, and subtle tonal coloration in a 1U metal rackmount enclosure. Whether you're recording vocals, acoustic instruments, or other sensitive sources, the PRE-22 provides pristine, dynamic, and detailed sound, making it an ideal choice for professional-quality recordings in any studio environment.
With +70dB gain, it effortlessly handles low-output mics and sensitive sources while maintaining an ultra-low noise floor. Its transistor-based input stage ensures tonal accuracy, adding expressive character in the mids, while the smooth, musical top-end remains free from harshness. A built-in high-pass filter cleans up low frequencies, preventing muddiness and ensuring a cleaner signal from the start.
The PRE-22 combines vintage analog warmth with modern precision, offering a professional-grade
solution in a robust rackmont metal enclosure. The external AC transformer reduces hum and
electromagnetic interference, while the internal linear DC power supply ensures stable, clean operation without switching power supply noise.
