TOPPING HS02 | High-Performance USB Audio Isolator for Thoroughly Eliminating Ground Loop Noise

Born for Pure Audio, Bid Farewell to Annoying USB Computer Ground Noise

The TOPPING HS02 is a high-performance USB audio isolator designed to solve ground loop noise in computer audio systems, supporting high-resolution audio transmission up to PCM 32bit/768kHz and DSD512. Through its fully isolated circuit design, it effectively blocks power noise and digital noise from the computer's USB port, providing a clean digital signal to your DAC or audio interface, thereby significantly improving sound quality. The HS02 features an extremely low 0.073μs latency, ensuring audio synchronization is unaffected.

Compared to general USB hubs or filters that only address partial power issues, the HS02, through its thorough current and data isolation technology, can reduce ground loop noise by up to 50dB, fundamentally solving the computer ground noise problem that troubles audiophiles and music creators.

For systems that inherently have no noise issues, the perceived improvement in sound quality may be limited.

TOPPING HS02/BK USB FAQ

Q：Can the TOPPING HS02 USB2.0 High Performance Audio Isolator solve the buzzing sound when my computer is connected to speakers?

▼

A：Yes. The HS02 is specifically designed to isolate USB ground loops, effectively eliminating or significantly reducing buzzing and current noise caused by computer USB, suppressing up to 50dB of noise.

Q：How is the HS02 different from other USB filters on the market?

▼

A：The main difference lies in the isolation method. The HS02 uses complete electrical isolation to thoroughly block the ground path, while most common filters passively remove noise. For stubborn ground loop issues, the HS02's effect is more fundamental and significant.

Q：Do I need to install drivers for the HS02?

▼

A：No. The HS02 is a plug-and-play device. It acts only as a medium for signal transmission and isolation, without altering USB signal content, thus requiring no drivers to operate on Windows, macOS, or Linux systems.

Q：If my DAC has high power consumption, will the HS02 affect power supply?

▼

A：The HS02 has an independent low-noise power supply internally to power the isolated USB port, providing standard 5V/500mA power, sufficient to drive most USB DACs. However, for a very few devices requiring higher current, it is recommended to check their specifications.
