Dualchannel professionalgrade passive audio isolator Key benefits Complete isolation of the potential difference between two systems to prevent grounding problems and AC noise interference, protecting input components from excessive potential differences and ensuring secure audio signal transmission. Passive, no power supply required, preserving signal integrity with a simple, reliable design. Permalloy material based isolation for robust performance and effective noise rejection. Dual XLR inputs and XLR outputs for flexible professional connections; supports unbalanced input to balanced output and balanced input to balanced output. Each channel includes a common ground and a noncommon ground switch for flexible grounding options and further noise management. Reduces noise when connecting equipment such as cameras, simultaneous interpretation gear, laptops, and electronic instruments to a mixer. Specifications and compatibility Type: Dualchannel passive audio isolator Material: Permalloy based isolation components Inputs/Outputs: Dual XLR inputs and dual XLR outputs Signal flow: Unbalanced input to balanced output; balanced input to balanced output Grounding: Each channel provides a common ground and a noncommon ground switch Power: None required (passive design) What problems it solves Eliminates ground loop hum and interference caused by grounding differences between two connected systems Prevents damage to input components from potential differences Removes noise introduced when devices such as cameras, interpretation equipment, laptops, or electronic instruments are connected to a mixer Use scenarios Film or video production: connect a camera's audio output to a mixer or audio interface while eliminating ground loop noise and protecting the input stages of the equipment; maintain clean, reliable audio capture on location. Live interpretation or conference setups: connect simultaneous interpretation gear to a mixer with reduced noise and stable signal integrity, improving clarity for listeners. Studio or portable music setups: connect laptops or electronic musical instruments to a mixer with minimized noise and preserved signal quality during recording or live performance. Notes Designed to maintain signal integrity in professional audio environments with standard XLR interfaces No external power or batteries required due to its passive design Keeps the original function and performance characteristics intact while providing practical ground loop and noise reduction benefits
