Product Overview Normally, the voltage of the shielding layer of the audio or stereo signal transmission cable is 0V. When the ground loop/ground loop phenomenon exists in the multimedia system, the level will fluctuate around 0V, and more seriously, it will cause serious distortion of the audio stereo signal and interference phenomena such as low-frequency AC "buzzing" sound and high-frequency "buzzing" sound of on-board sparks. When the audio signal transmission distance exceeds 100 meters, it is easy to generate high ground loop voltage. If the ground loop voltage is too high, it may even cause the signal source or receiving equipment to be burned, and in severe cases, it may endanger the user's life. The audio isolator SQ48 can eliminate and solve the above situations. Product Features √.
