Dual-channel professional-grade passive audio isolator, using Permalloy material audio isolation cattle, connector, so that the signal is completely connected. Dual and XLR XLR inputs, XRL XLR outputs. Unbalanced signal can be input into balanced signal output, balanced signal can be input into balanced signal output. Each channel has a common ground and non-common ground switch. It can completely isolate the potential difference between the two systems, avoid AC noise interference caused by grounding problems, and prevent damage to the input components of the device due to excessively high potential differences. Achieve the secure transmission of audio signals. Noise from distance transmission inconsistently; noise from equipment and equipment impedance mismatch. It is also suitable for a series of sound equipment systems such as large-scale outdoor performances, Fast Charging protection, sound engineering, conferences, entertainment venues, exhibitions, etc. It is a necessary equipment for audio system cascade. Input Impedance: 600Ω (AC Impedance) Output Impedance: 600Ω (AC Impedance) Frequency Response: 20Hz-20kHz (Less than 0.3dB REF 1kHz) Rated Loss: Less than 0.7dB (REF 1kHz 1VRMS) Insulation Resistance: DC 1000V 100MΩ Isolation Voltage: AC 50Hz-60Hz 0V-1500V Connector Type: 6.35mm female/6.35mm male AV Connector Function: Supports conversion between all audio interfaces, including unbalanced and balanced conversion.
