The benchmark accessory for noise-free USB audio
Discover the Omni USB, iFi Audio's essential tool for all digital hi-fi enthusiasts seeking pure, detailed and uncompromising audio reproduction. A true technological masterpiece from iFi Audio's SilentPower range, this device redefines USB connectivity by eliminating all electrical disturbances and interference that can degrade the signal between your source and your high-end DAC. With three-level isolation combining optical isolation, active noise cancellation and high-capacity battery power, the Omni USB ensures unrivalled clarity in digital transmission, making every musical detail more vivid and precise than ever before.
For Absolute Purity of Sound
The Omni USB pushes the boundaries of traditional USB performance, starting with optical signal isolation: the OptiLink USB module converts the data stream into light and then back again, ensuring complete separation between input and output without electrical interference. This innovative approach eliminates interference, stray currents and unwanted noise at the source.
For extended listening sessions without disruption
While mains power is often a major source of noise, Omni USB cuts this link by relying on a large-capacity internal battery (8,000 mAh). Powered by this battery, the device delivers exceptionally pure energy for extended listening sessions without disruption. Thanks to its PurePort outputs featuring ANC technology, each connected USB device (including DACs and other sensitive audio equipment) benefits from a clean power supply and signal, free from the usual electrical noise. TheOmni USB doesn't just isolate and filter: it shows you the effectiveness of its technology in real time via its TFT colour display. You can view power noise, voltage, current and power for each port. Perfect for optimising your audiophile setup, the device also includes advanced options such as high-resolution digital-to-digital conversion (up to 192 kHz/24-bit) and the ability to connect older DACs via dual coaxial outputs.
