Product use: This USB A male to dual XLR male audio cable converts desktop computers and laptops with a USB A interface into dual XLR male stereo output. The red XLR connector is for the right channel output and the black connector is for the left channel output. The output end can be connected to the XLR input port of power amplifiers, active speakers, or stage sound equipment. Note that this product supports one-way signal conversion only—USB outputs audio signal to XLR; it does not support input from XLR sources such as microphones. When connecting to the MIC input on a mixer, ensure the 48V phantom power switch is turned off to prevent damage to the adapter's decoding chip. The cable features a Y-type splitter design with the splitter located approximately 50cm from the XLR plugs. The total length is 100cm, with 100cm from USB to the splitter and 50cm from the splitter to each XLR output. It incorporates a 32Bit/384Khz decoding chip, offering higher sampling rate, improved sound clarity, stronger driving capability, and better signal-to-noise ratio compared to standard 16Bit chips, resulting in enhanced audio performance.
