The DC input voltage for this isolator is around 5V-5.5V, and must NOT exceed 6V. Due to the DC port design, it is easy to accidentally plug in the wrong power supply and burn out the unit. If the input exceeds 6V, the isolator will be damaged. Symptoms of damage: Although the power LEDs on both the transmitter and receiver stay lit, the communication LED will blink slowly continuously, and connected devices will not respond. Damage caused by overvoltage will require repairs and shipping costs to be paid by the customer.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003eDescription:\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e* The new generation Hi-Fi USB Isolator is here!

How does this device improve sound quality?\u003c\/div\u003e\n\u003cdiv\u003eA: This device uses optical transmission to physically isolate interference caused by playback devices (such as computers) to the DAC. Scientifically speaking, it effectively reduces background noise floor in audio playback. Improvements in other areas may vary depending on personal listening preferences.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e2. Does this device require driver installation?\u003c\/div\u003e\n\u003cdiv\u003eA: No, it is driver-free and plug-and-play for maximum convenience.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e3. Is the power supply for the receiver critical?\u003c\/div\u003e\n\u003cdiv\u003eA: Yes, power quality on the receiver side is essential. The ground wire of the receiver connects directly to the digital interface or DAC. If the receiver's power supply is noisy, interference can transfer through the ground wire to the DAC or pre\/power amplifiers. Choosing a high-quality linear power supply directly impacts the final audio quality of your DAC.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e4. Is an external power supply necessary for the transmitter?\u003c\/div\u003e\n\u003cdiv\u003eA: Whether the transmitter requires an independent power supply depends on the USB power delivery capability of the connected device. If connected directly to the rear USB port of a desktop motherboard using a high-quality USB cable, external linear power for the transmitter is not necessary. However, if the host device has weak power output (such as a smartphone), using an external power supply is recommended. For optimal audio performance, using external linear power supplies on both ends is recommended whenever conditions permit.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/www.comseek.com\/image\/catalog\/103796\/103796-01.jpg\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/www.comseek.com\/image\/catalog\/103796\/103796-02.jpg\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg src=\"https:\/\/www.comseek.com\/image\/catalog\/103796\/103796-03.jpg\"\u003e\u003c\/div\u003e","brand":"Beibu Gulf Engine","offers":[{"title":"Default Title","offer_id":41156050223153,"sku":"103796","price":151.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/103796-1.jpg?v=1785824862","url":"https:\/\/www.thanksbuyer.com\/it\/products\/ssssssssss","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
