Effectively eliminate the noise introduced by the ground loop The noise can be reduced by up to 50dB in real world measurement. Ultra Low Latency The Latency is only 0.073us, which fully meets hifi and professional applications' needs. High speed is also highly compatible HS02 supports automatic identification of USB2.0 transmission at low speed, full speed, and high speed. The powerful transmission capability is compatible with high resolution audio such as PCM32bit/768kHz and DSD512 Native. Switching between two interfaces The HS02 has two input interfaces (including a USB-B and a Type-C) and two output interfaces (including a USB-A and a Type-C), either of which can be selected by an input switch or an output switch. Note: Input is used to connect to the computer, output is used to connect to USB devices. Fully Isolated Design The HS02 has a fully isolated design, which does not introduce new interference when the auxiliary power supply is used while the audio signal is isolated from ground loop interference. Say goodbye to the ground loop and hum.
