Olympus Cleanus The Olympus Cleanus is an entirely passive mains filter featuring Entreq’s Tungsten Inside technology. More accurately described as a high-frequency separator, it works by drawing high-frequency interference and other contaminants away from your audio system’s mains supply, dramatically reducing the noise that reaches your components without any loss of dynamics or musicality. Olympus Cleanus includes all necessary cables for connecting to your system. Product Description Every domestic mains supply carries contamination. Appliances throughout the home – from LED lighting and refrigeration to routers, chargers and switching power supplies – inject high-frequency interference back into the mains. This noise is not inaudible. It raises the noise floor across your entire system, masking fine detail, compressing dynamics and reducing the sense of space and separation in your music. Rather than focusing on what happens after the signal leaves source components, the Cleanus range addresses what happens before, at the point where your system meets the mains supply. The Olympus Cleanus connects to a spare mains socket via an Entreq power cable, where it acts as a passive high-frequency separator. Rather than filtering the signal in the conventional sense, it draws contamination away from the supply, absorbing high-frequency noise into Entreq’s Olympus-grade mineral mix featuring Tungsten Inside technology. The result is a cleaner, quieter supply reaching your components — and a noticeably darker, more resolved background to your music. The Entreq Difference Where conventional, active, mains filters and conditioners can impose dynamic constraints, trading noise reduction for a loss of life and energy, the Olympus Cleanus is entirely passive. It takes nothing away from the music. There is no compression, no loss of dynamics, no sense of the system being held back. The background simply becomes quieter, allowing the music to emerge with greater purity, transparency and natural ease. This is Entreq’s approach at its most characteristic: removing what should not be there, rather than adding anything new. Going Further The Olympus Cleanus features a silver binding post, allowing it to be connected to an Entreq ground box via an Eartha ground cable. This grounds the Cleanus itself, giving the absorbed noise an additional path to dissipate and further lowering the noise floor. Connecting an Olympus Cleanus to a Silver Tellus Tungsten or Olympus 10 T ground box will deliver an even greater impact. For systems already benefiting from Entreq grounding, the Olympus Cleanus represents a highly effective complementary step, addressing the mains supply while your ground boxes address the signal path. Together, they form a comprehensive approach to noise management that few other solutions can match. As with all Entreq products, we recommend consulting with your local distributor to get the best advice for your system.
