JORMA Power — Filter Reference

Jorma 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 direct current to protect your hifi system.

Divide and conquer

Without this, sound can be harsh, boomy and inconsistent. 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 hifi components.
