Description: The of the baffle is plated with anti-rust conductive coating and designed with points, which can effectively prevent electromagnetic radiation. The coaxial interface has undergone more than 10, 000 times of plugging and wear and 24-hour salt resistance tests. The internal plastic core is a lead-free, environmentally friendly and high-temperature material to stable signal mission and durability. TX178S high-quality optical fiber , as well as the standardized use of the chip reference circuit, the complete output of the optical fiber signal. The thickness of the circuit board is 1.5mm, and the back is covered with a ground wire shielding layer to effectively prevent deformation and electromagnetic interference.<br><br>Notice: 1. This daughter card is suitable for most computer motherboards, but not all motherboards. Before purchasing, please check carefully whether there are 2pin or 3pin ports with the words SPDIF-OUT, SPDIF-O, HDMI_SPDIF, JSP1, etc. on your motherboard (individual motherboards are 5pin). If there is no SPDIF header, this daughter card cannot be used. In addition, some low-quality motherboards have SPDIF pins but no signal output, Such motherboards also cannot use this daughter card. 2. Before connecting, please make sure the connection is correct, wrong connection may cause the daughter card or motherboard to burn out.
