Audio Noise Filter - Eliminate Interference and Enhance Sound Quality

Brand

<li>Welcome to our shop! Introducing our Stereo Audio Isolator, designed to provide high sensitivity and high reductivity for a full and pure sound quality. Made with aerospace materials, this isolator adopts two independent audio transformers for superior performance. With two connection methods, you can easily input and output through the 3.5mm headphone jack or directly connect through the two blue wiring jacks. This makes it a versatile option suitable for small cars and other indoor devices. The main function of this isolator is to eliminate current sound. It effectively eliminates the current noise of the AUX common ground by isolating the input and output ground lines with the transformer, ensuring no common ground interference. To determine if the noise is caused by common ground, you can follow these steps: 1. Use the earphone to connect with the car MP3 and car navigation AUX. If there is no noise heard from the earphone, it confirms that the noise is caused by the common ground. 2. Connect a battery-powered mobile phone or MP3 to the AUX of the car's center console using an audio cable. If there is no noise, it confirms that the previous noise was caused by common ground. 3. Test with a computer, amplifier, audio, or CD. Use a passive headset to listen for noise when plugged into the computer or amplifier. If there is no noise, it indicates that the noise is caused by the common ground. 4. If you experience a current sound after starting the car with an installed amplifier, this product can effectively solve the problem. 5. If there is a current sound between the amplifier and the speaker or audio, this isolator can be installed between them to eliminate the noise. 6. When using a laptop connected to a projector and amplifier simultaneously, there may be noise. In this case, you can use this product between the headphone jack and amplifier to eliminate the noise. Made of ABS material, this Stereo Audio Isolator measures approximately 45x30mm/17.7x11.8in. It is a reliable solution for improving sound quality and eliminating common ground noise. 100% Satisfaction: Our customers are our top priority.
