HLabs PRE169DC: Studer-style preamp with a modern soul

The Karno HLabs PRE169DC SEPIA Module faithfully reproduces the input stage of the legendary Studer 169 console, offering transparent sound and massive gain of up to 67 dB. For a fuller, more musical timbre, a Carnhill output transformer-the same one used in the Neve 51 series consoles-is integrated, all packed into a compact SEPIA System Module.

SEPIA: Karno's revolutionary modular platform.

Developed by Karno, SEPIA is an innovative hardware platform designed for engineers and creative people. With patented technology and zero compromise on sound, SEPIA enables portable, integrated and flexible configurations, delivering real, high-performance analog instruments. The project was supported by industry and awarded a Smart Innovate UK grant.

Professional performance for studio and music production

The PRE169DC is ideal for vocal recordings, acoustic instruments and amplifiers, thanks to its wide frequency response and extremely low signal-to-noise ratio. Built-in controls include +48V phantom, pad, polarity switch and variable high-pass filter, making it a complete tool for any session.
