## Description

Topping HS02 USB 2.0 Isolator 🔶It is a high-performance USB isolator with high speed, high compatibility and low latency of 0.073us. The isolation withstands up to 1500VDC. 🔶With two input interfaces (USB-B & Type-C) and two output interfaces (USB-A & Type-C), it is selectable for you to meet your needs. 🔶With the powerful compatibility of PCM32bit/768kHz and DSD512 Native, it is suitable for most USB decoders. 🔶For USB devices which are powered via the USB port, HS02 requires 5V power supply to provide sufficient power for reliable operation of the USB device. Please connect the power supply to the other input jack of the HS02. Attribute Measured: 5.9cm x 3.9cm x 18cm Weight: 45g Power input: DC5V/2A Power output: DX5V/800mA Signal input: USB-B / Type-C Signal output: USB-A / Type-C Voltage Isolation: >1500VDC USB interface: USB2.0 (Supports low, full and high speed mode by automatic detection) Delay: 0.073us (Typical value) Note: ● The toggle switch allows you to select different functions. ● Input is used to connect to the computer, output is used to connect to USB devices. ● We recommend connecting the HS02 directly at the PC (USB root port instead of an USB hub).

Review: Hub con aislamiento galvánico para aislar tu dispositivo de audio (como por ejemplo un DAC) del PC. Este hub aisla completamente el ruido electrico que las computadoras producen hacia tu dispositivo de audio. Indispensable para equipos de audio y DAC's de alta calidad.
Review: I was dealing with GPU noise from my NVIDIA RTX 3060 12GB when a game was running with both my iFi Zen Air DAC and also my Topping DX3 Pro+. The reason is because my headphone amp is a valve/tube amp so it must be earthed due to the very high voltages, and this meant there was a ground loop with the noise from my PC. I tried the usual tricks of putting everything on the same extension lead, which while it did reduce the noise, it did not eliminate it and that was problematic when using my Beyerdynamic DT990 Edition 600 Ohm headphones. So I went ahead and got this USB isolator since it supports USB 2.0 hi-speed (so it should actually handle above PCM768 @ 32-bit and DSD512/48 without issues, but I do not have a DAC capable of going higher to test). While it was working, and the computer noise was ENTIRELY eliminated, I was getting random and very often cutouts from the audio. Windows and Audirvana could still 'see' the DAC, just that the audio stream was getting cut off for some reason. This was plugged into one of the USB 3.0 ports (*just* 3.0, not Gen 1 or higher). I decided to try plugging it into a USB 2.0 port as I do know there can be compatibility issues with 3.0 ports, and I also shortened the cable to 1.5m. This totally fixed the issue I was having, and now I can easily send PCM768/DSD512 to the Topping without any dropouts of any kind. The iFi also handles DSD256 without any issue too. Even new motherboards released today have USB 2.0 ports specifically because 3.0 (and higher) can't always handle 2.0 devices correctly, and after reading the datasheet for the USB isolator chip they're using, it is very specifically for 1.0, 1.1 and 2.0, and requires incredible precision on the circuit layout to work correctly - this is one reason why this is expensive. So it gets 5 stars because not only did it entirely eliminate the GPU noise, but the big improvement in the noise floor seems to have given the valve/tube amp a bit more room to breathe, as I noticed a subtle improvement in the attack of synthesizer sounds. Your mileage will vary here obviously, such as how well trained your ears are, what gear you're using and what audio format you're using.

## Features

- 👍 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.
- 👍 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.
- 👍 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.
- 👍 Ultra Low Latency ▶️ The Latency is only 0.073us, which fully meets hifi and professional applications' needs.
- 👍 Effectively eliminate the noise introduced by the ground loop ▶️ The noise can be reduced by up to 50dB in real world measurement.
