Description Isolate the potential difference between the two systems to prevent damage to the input level of the equipment due to excessive potential difference. Achieve safe transmission of audio signals and remove noise generated by the connection of audio equipment; solve the AC noise caused by power consumption, wiring, lighting interference and other reasons. Noise generated by connecting laptops to mixers, and noise generated by connecting electronic instruments to mixers. Noise generated by long-distance transmission between devices and 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 equipment, etc. Parameters: Input impedance: 600/10K (AC impedance) Output impedance: 600/10K (AC impedance) Input interface: 3.5mm-Female Output interface: XLR-Male Mode: Passive Main function: Stereo dual-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 100 Isolation voltage: AC 50Hz-60Hz 0V-1500V Colour:black Material:Aluminum Alloy Due to different batches, there may be differences in product appearance and printed text, which not affect use Package Contents: 1 * XLR Audio isolator Only 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. The measurement allowed error is +/- 1-3cm.
