Audio Ground Loop Isolator

Product Introduction：There are many situations where a notebook is used as a sound source player for live sound reinforcement, such as multimedia teaching, on-site tuning, audio post-production, etc., all use notebooks, because the cable output from the notebook to the mixer is unbalanced. The signal transmission method, the anti-interference ability of the unbalanced transmission method itself is quite poor. When the equipment is connected to the laptop, the ground potential difference will directly cause serious AC noise in the speaker. It will influence the audience's audiovisual effects, making the sound very bad. This is a headache for many audio engineers.    In addition, when the charger is used in the car to supply power to the car's computer, GPS, MP3, mobile phone and other devices, and it is also used the 3.5mm AUX audio interface, at this time, the car audio system will have AC noise. In order to solve these problems, the audio isolation transformer can be used to completely isolate the potential difference between two systems, and also can suppress the noise caused by the common ground. Meanwhile, it prevents the damage to the input stage of the equipment by the excessive potential difference, and realize the safe transmission of audio signals.Features:     1. Compact and easy to carry.     2. Completely eliminate the AC noise caused by the common ground and enjoy pure   sound quality.     3. Equipped with a grounding switch to help eliminate ground loop noise. Technical parameters:     1. Frequency range: ±0.5dB, 50Hz ～20kHz     2. AC impedance: 600Ω: 600Ω     4.
