Features 1. Effective Noise Elimination: The sound signal isolator effectively isolates the potential difference between two systems to avoid AC sound interference caused by grounding issues and prevents equipment input damage due to excessive voltage differences. 2. High Performance: Easy to use with RCA (L/R) input and output, includes a common ground switch to prevent signal distortion. 3. High Fidelity Sound: Plug and play design with noise cancellation for pure, clear, balanced, and natural sound quality. Delivers accurate tone reproduction and an enhanced sound field. 4. Wide Applications: Suitable for radio stations, TV stations, professional audio setups, laptop-to-console connections, simultaneous interpretation systems, video system integrations, and other audio system connections. Helps prevent static discharge and protects connected equipment. 5. Campus Broadcast and Large Conferences: Effectively eliminates loud buzzing noises in recording studios or microphone-to-DVR setups. Resolves current noise issues between amplifiers and speakers when connected before the amplifier. 6. Projector and Amplifier Use: Solves AC noise issues when connecting projectors and amplifiers simultaneously, even when using battery-powered laptops. Restores clean audio when installed.
