The SilentPower by iFi OMNI USB is an innovative USB isolator that redefines the standards of audiophile USB signal transmission. Thanks to complete electrical isolation through optical isolation combined with active noise suppression, this device reduces electromagnetic interference to an unprecedented minimum. With its ultra-fast USB 3.2 connectivity and integrated 8,000 mAh battery, it enables a completely independent and noise-free power supply. The OMNI USB has been specifically designed to eliminate the problem of electrical noise at the source. It starts with the included USB OptiLink, which converts the incoming data signal into light through optical isolation. This signal is then transmitted to the OMNI USB, where it is converted back, completely isolating the input and output. This way, electrical noise, interference, and stray currents are removed. From there, the OMNI USB offers five ANC-capable PurePort outputs for uncompromisingly clean and quiet USB connections. A dynamic diagnostics feature visualizes voltage fluctuations in real-time and documents the efficiency of the noise suppression. The OMNI USB is ideal for high-quality music servers, streamers, and demanding USB DACs, setting new standards for digital music transmission. Its combination of isolation, innovation, and independent power supply forms the foundation for unadulterated sound enjoyment in the high-end segment. The intelligent charging electronics ensure gentle battery care by maintaining the charge level optimally between 20 and 80 percent. By isolating all USB devices from the source device, the risk of ground loops is eliminated. Even during continuous operation via the power supply, performance remains consistently at the highest level. The robust housing and thoughtful connection architecture emphasize the professional aspirations of this exceptional product.
