1. Isolate the potential difference between the two systems to prevent damage to the input level of the equipment due to excessive potential difference2.Achieve safe mission 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 inst ent to a mixer4. Noise generated by the long-distance mission between devices and the noise generated by impedance mismatch5.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: 6.5-6.5Input impedance: 600Ω/10K (AC impedance)Output impedance: 600Ω/10K (AC impedance)Input interface: TSOutput interface: TSMode: PassiveMain 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 100ΩIsolation voltage: AC 50Hz-60Hz 0V-1500VColour:BlackMaterial:Plastic + MetalPackage Contents:1 x Audio IsolatorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
