The new shielding technology is the improved shielding technology. The supply appliances are designed separately from the supply. The external supply is equipped with a shielding magnetic ring to completely isolate the AC electromagnetic wave from the DC supply to the signal is not . Soft soft switch function soft soft function to avoid the impact sound of "poof" when starting up. Stable filter current and stable voltage doubling rectifier filter circuit can effectively filter out the interference of AC signal. Two groups of balanced supply, two groups of balanced supply, balance the output signal, stabilize the voltage and suppress common mode interference. Phantom supply and high-quality circuit can effectively prevent thousands of disturbances and eliminate whistling. supply interface: 48V phantom supply Output interface: Standard balanced output Input port: Standard balanced input Output voltage: DC48V consumption: less than or equal to 5W Noise: less than or equal to 18uv Plug Type: US Plug, it applies to Canada, India, Mexico, Thailand, Taiwan, the United States, the Philippines and so on. Type: A Colour: black Material: metal Size: 26x20x6CM Package Contents: 1 * Phantom 1 * US plug Only the above package content, other products are not included. Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
