Dual-channel professional-grade passive audio isolator for secure audio signal transmission. Utilizes imported Permalloy material for effective audio isolation. Completely isolates potential differences between systems to avoid AC noise interference. Prevents damage to input components from excessively high potential differences. Eliminates noise from connections between cameras, audio equipment, simultaneous interpretation devices, laptops, and electronic musical instruments. The dual-channel professional-grade passive audio isolator uses imported Permalloy material audio isolation cattle, ensuring that the signal is completely connected. It can completely isolate the potential difference between the two systems, avoiding AC noise interference caused by grounding problems, and preventing damage to the input components of the device due to excessively high potential differences. Achieve the secure transmission of audio signals. Color: Black Material: Aluminum Alloy Package Contents: 1*Audio Isolator Only the above package content, other products are not included.
