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 principle of Power Filter Plugs is to reduce resonance, but each is designed with a specific aim. The Booster is great at reducing high frequency noise, the Fine Grade Filter is tailored to reduce multi-frequency noise, and the Resonance Damper targets radio frequency interference (RFI). All plugs feature a high-spec over-voltage protection to reduce the risk of surge hardware damages.
