JORMA Power — Filter Plug

Jorma Power

Filter Plug

Control that you can hear

Power filter Plugs is a series of three filters designed to reduce the unwanted noise inherent in your electricity supply. By cleaning your mains system, this reduces resonance factors that can pollute the sound, offering valuable protection to sensitive, high specification hi-fi equipment.

The dream team

The basic principles of Power Filter plugs are to reduce noise created by the mains power supply and prevent hardware damage. There are three models, each designed with a specific aim. The Booster is a high magnitude noise reducer, damping a wide frequency range. The Fine Grade Filter is tailored to reduce resonant high frequency noise. And the Resonance Damper targets the mains resonances and noise-deriving free floating leads in the mains network.


All plugs feature high-spec over-voltage protection to reduce the risk of surge hardware damages, eliminating pops, noise and other unwanted sounds resulting from an uneven mains voltage.
