Jorma Audio Power Filter Reference

Purity in your home

In the home, mains electricity can be subject to distortion from domestic appliances, local industry and even your neighbours. Jorma Power Filter Reference cleans up your supply, removing noise and filtering direct current to protect your hi-fi system.

Divide and conquer

Jorma Power Filter Reference eliminates unwanted frequencies, leaving an audio signal with clarity and fidelity. Three separate filtered zones allow your entire system to be shielded from mains irregularities and interference between mutual hi-fi components.

Technical highlights

• DC blocker to remove low-frequency hum and bass bloom
• High-frequency suppression to reduce ripple and background noise
• Three isolated zones to keep components from interfering with each other
• High-current Schottky diodes for stable performance
• Heavyweight chassis for damping and mechanical stability
• Premium-grade printed circuit boards for reliability and transparency

Designed for demanding systems

Filter Reference is made for high-end audio systems, from digital sources and preamps through to power amplifiers. By delivering clean, stable power to every stage, it provides a foundation that lets the system perform to its full potential.

Performance you can hear

By blocking distortion across both low and high frequencies, Filter Reference lowers the noise floor. The result is smoother midrange, tighter bass and a more open, three-dimensional soundstage. With a supply free from distortion, the music flows naturally.
