Isolate the potential difference between the two systems to prevent damage to the input level of the device due to excessive potential difference. Achieve safe mission of audio signals and remove noise generated by the connection of audio equipment; solve the AC noise caused by reasons such as site power consumption, wiring, and lighting interference. Noise generated by connecting a laptop to a mixer, and noise generated by connecting an electronic inst ent to a mixer. Noise generated by long-distance mission between devices and noise generated by impedance mismatch. Scope of application: computer sound cards, active speakers, multimedia players, cameras, audio mixers, audio matrix switchers, audio separators, audio distribution amplifiers, set-top boxes, MP3 players, laptops, stereo audio amplifiers, audio switchers, integrated TV displays and other line-level audio devices, etc.<br><br>Parameters: Input impedance: 600Ω/10K (AC impedance) Output impedance: 600Ω/10K (AC impedance) Mode: Passive Main functions: Single channel physical isolation, balanced/unbalanced conversion Frequency response: 20HZ-20KHZ (± less than 0.2db ref 1khz) Rated loss: less than 0.7db (ref 1khz 1V rms) Insulation resistance: DC1000V 100Ω Isolation voltage: AC 50Hz-60Hz 0V-1500V Colour:black Material:Metal + Plastic style:A note:Storage bag color and style are random, don't accept the specified color and style Due to different batches, there may be differences in product appearance, color, and printed text, which will not affect the use.<br><br>Package Contents: 1 * 3.5 to XLR Audio Isolator 1 * Storage bag<br><br>Only the above package content, other products are not included.
