Product description: PROXLR-3 multifunctional audio isolator uses 2 E9818 shielded permalloy cattle as signal coupling conversion between input and output. The double-layer screen amnesty circuit design allows the signal between input and output to be fully isolated and converted. Independent two-channel design, rich interfaces, input 6.5XLR/6.35TRS/AUX3.5MM interface, output XLR interface. Different interfaces between input and output, balanced and unbalanced, high impedance and low impedance can all be converted to each other. It is equipped with a floating ground/ground mode switch, and an AUX 3.5mm small three-core input interface or can be used as a monitoring headphone output interface. Completely isolate the potential difference between the input and output systems to avoid hum interference caused by grounding problems, prevent damage to equipment input components due to excessive potential differences, and achieve safe transmission of audio signals. Eliminate the current sound generated by connecting laptops, cameras, broadcasting stations, simultaneous interpretation equipment, electronic musical instruments and other equipment to the mixer (audio), and the sound caused by impedance mismatch between equipment and equipment noise. Technical Parameters: Model: PRO XLR-3 Input impedance: 600Q/10K (AC impedance) Output impedance: 600Q/10K (AC impedance) Input interface: 3.5AUX*1XLRX1, 1/4 inch TRSx1 Output interface: (balanced/non-flat) XLRX1 mode passive Isolation configuration: E9818 shielded permalloy cow*2 Frequency response: 20HZ-30KHZ ( Less than 0.2db ref 1khz Fixed loss: Less than 0.7db (ref1khz 1Vrms) Insulation resistance: DC1000V 100Q Isolation voltage: AC50HZ-60Hz0V-1500V Size:100mm x 52mm x 52mm Main functions: physical isolation of two channels, balanced/unbalanced mutual conversion Material: Aluminum alloy colour: black Package Contents: 1 x 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.
