The Topping HS01 is a compact, high-speed, ultra-low (0.29 µs) latency USB 2.0 noise filter that can reduce much of the electrical noise or network grounding problems that often occur at the USB output of computers. The noise reduction due to electrical isolation can be as high as 50dB. The HS01 is compatible with high resolution audio streams up to 768kHz/32bit PCM and DSD512. The device can be used with both USB powered and self-powered devices, in the former case an external USB power supply (e.g. phone charger) must be connected to the USB-C input of the HS01. The device only supports USB 2.0 devices, USB 1.0 devices (e.g. USB keyboard, mouse) may cause interference and should not be used with them.
