1. Isolate the potential difference between the two systems to prevent damage to the input level of the equipment due to excessive potential difference 2.Achieve safe transmission of audio signals and remove noise generated by the connection of audio equipment; solve the AC noise caused by the use of electricity, wiring, lighting interference, etc. 3.Noise generated by connecting a laptop to a mixer, and noise generated by connecting an electronic instrument to a mixer 4. Noise generated by the long-distance transmission between devices and the noise generated by impedance mismatch 5.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 equipment, etc. Model: 6.5-6.5 Input impedance: 600Ω/10K (AC impedance) Output impedance: 600Ω/10K (AC impedance) Input interface: Output interface: Mode: Passive Main function: Single channel physical isolation, 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:Plastic + Metal Package Contents: 1 x Audio Isolator Only the above package content, other products are not included.
