It can take hours to troubleshoot this issue or no time at all with TOPPING's HS02 Audio Isolator. \nFully-isolated design\nThe HS02's fully-isolated design keeps your audio signal protected from interference, including the auxiliary power supply, stopping ground loop noise in its tracks. \nThis thing knows its ABCs\nWith inputs for USB B and C, and outputs for USB A and C, the HS02 can handle a number of interface scenarios. Simply plug in the cables you need and select the appropriate path with the input and output switches. \nReady for the Hi-fi life\nThe HS02 is compatible with high resolution audio such as 32-bit/768kHz PCM and DSD512 Native. \nNeed for speed\nWith a latency speed of 0.073us, the HS02 fully meets hi-fi and professional application needs. \nWorks with all power requirements\nIf your DAC receives audio information and power from the same USB cable, simply plug a 5V charger into the USB-C input of the HS02. Don't worry: the auxiliary power supply will not add noise. If your DAC only receives audio information from the USB input, plugging a 5V charger into the HS02 isn't necessary. \nProduct highlights\n\nReduces up to 50dB of ground loop noise\n0.074us latency speed\n32-bit/768kHz PCM compatible\nDSD512 Native compatible\n\nSpecs\n\nAudio signal isolation voltage: >1500KVRMS\nAuxiliary power isolation: Yes\nInputs: USB-B, USB-C\nOutputs: USB-A, USB-C\nDimensions: 5.9cm x 3.8cm x 1.8cm\n\nWhat's included\n\nHS02 Audio Isolator\nUSB cable\nUser manual\nWarranty card\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613181989100.jpg?v=1741112292","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180416236.jpg?v=1741112292","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180547308.jpg?v=1741112293","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180514540.jpg?v=1741112293","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180842220.jpg?v=1741112293","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180645612.jpg?v=1741112293","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180809452.jpg?v=1741112293","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180743916.jpg?v=1741112293","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180678380.jpg?v=1741112293","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180481772.jpg?v=1741112293","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180973292.jpg?v=1741112293","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180940524.jpg?v=1741112294","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180580076.jpg?v=1741112294","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180612844.jpg?v=1741112294","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613181071596.jpg?v=1741112294","https://cdn.shopify.com/s/files/1/0225/2721/3642/products/apos-audio-topping-usb-interface-topping-hs02-usb2-0-audio-isolator-38613180776684.jpg?v=1741112294"],"price":99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:59.616Z"},"share_url":"https://firestarter.network/l/lst_m7f6Jz8I","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
