Supports XLR + 6.5 + input and output conversion PRO MAX2 Audio Isolator Current Sound Noise Cancellation Mixer Microphone Common Ground Filter Multifunctional Noise Isolator Meter Dual-channel professional-grade passive audio isolator, 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. Remove the noise generated by the connection between the camera and the audio equipment; the noise generated when the simultaneous interpretation equipment is connected to the mixer; the noise generated by the laptop connected to the mixer; the noise generated by the electronic musical instrument connected to the mixer. 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.
