iFi SilentPower OMNI USB

The SilentPower OMNI USB is a flagship USB conditioner designed to isolate high-end DACs and digital audio systems from electrical noise and interference. Its triple-layer approach combines optical isolation, Active Noise Cancellation, and an internal 8,000mAh battery to provide a clean, electrically isolated path for USB audio. The included USB OptiLink converts incoming USB data to optical before transmitting it to the OMNI USB, electrically isolating the source from downstream audio equipment. Five ANC-enabled PurePort outputs provide conditioned USB connectivity, including dedicated power outputs for compatible bus-powered devices. An internal GMT clock system, real-time TFT monitoring, USB data rates up to 10Gbps, and 24-bit/192kHz digital-to-digital conversion further expand its capabilities. The OMNI USB also provides coaxial and optical S/PDIF outputs, external clock synchronization, and PD3.0 fast charging for compatible source devices. Optical Isolation The included USB OptiLink converts the incoming USB data signal to optical for transmission to the OMNI USB, where it is converted back to electrical data. This creates electrical separation between the source and downstream audio equipment, helping prevent noise, interference, and stray currents from traveling through the USB connection. ANC-Enabled PurePort Outputs Five PurePort outputs use Active Noise Cancellation to further reduce electrical noise after optical isolation. Two USB-A ports provide power and data, two USB-A ports provide dedicated power, and a USB-C PurePort provides additional conditioned connectivity. 8,000mAh Battery Power An internal 8,000mAh lithium-ion battery allows the OMNI USB to operate independently from AC power during listening. Intelligent battery management maintains the battery between approximately 20% and 80% during managed charging to help extend battery life. GMT Clocking & Real-Time Monitoring The OMNI USB incorporates SilentPower's internal GMT clock system with external BNC clock synchronization capability. Its color TFT display provides real-time monitoring of power-supply noise, voltage, current, and power consumption across available USB ports.
