Feature: 1. Ground Loop: The noise isolator utilizes premium sound coupling components and gold plated RCA connectors, supports RCA and 3.5mm AUX inputs and outputs. It can effectively remove noise such as hiss, hum and interference caused by the ground loop, and realize excellent sound fidelity. Simple installation, correct wiring can be used. 2. Stable Anti Interference: Stable performance, aluminum alloy shell, strong anti interference ability. Can be used to remove the noise generated by the computer connected to the display sound, laptop connected to the mixer, equipment and equipment after a long distance transmission is not common ground, equipment and equipment impedance mismatch. 3. Compatible Devices: Suitable for any RCA and 3.5mm AUX interface devices, including mixing consoles, sound cards, recording studios, conference room amplifiers, smartphones, tablets, computers, mp3 players, speakers, car sound systems, home stereo, KTV projects, power amplifiers and so on. 4. Multifunctional Adaptability: Ground loop noise isolator with common ground and non common ground switch can easily switch between common ground and non common ground settings with just one key switch. Designed to perfectly adapt to a variety of complex sound and electrical environments. 5. Isolation Transformer: Guard your sound equipment from potential damage caused by excessive potential differences. The transformer effectively isolates the potential difference between two sound devices, ensuring guard of the input components. Prevents equipment from being burned by strong electrical shocks. 6. Function: It can completely isolate the potential difference between two systems, avoid AC sound interference due to grounding problems, prevent damage to the input components of the equipment caused by excessive potential difference, and realize the safe transmission of sound signals. Specification: Item Type: Noise Isolator Material: Aluminum Alloy Input Impedance Range: 600Ω-10KΩ (AC Impedance) Output Impedance Range: 600Ω-10KΩ (AC Impedance) Frequency Response: 20HZ-20KHZ (±
