Specification: Origin: Mainland China Type: Module Condition: New Product size: 54.00x33.00x14.0mm Product size: 2.13x1.3x0.55inch Introduction to the functions of audio isolation transformer: 1. Part selection: Two independent audio transformers are used, and the transformer material is made of aerospace materials, 2. High sensitivity and high reducibility, with a sensitivity of 10-20DB higher than similar low-end transformer. The sound is full and pure. 3. Circuit design: Stereo dual channel independent design, circuit board specification: 45MM X 30MM, very small, suitable for small space and other car interior installation. 4. Connection method: There are two connection methods, which can be input and output through a 3.5mm headphone socket or directly connected through two blue connection sockets. 5. Main function: Eliminate current sound. The common ground isolation audio transformer eliminates the current sound caused by AUX common ground, and the output and output ground wires are isolated through the transformer, so there will be no common ground. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 x Stereo Audio Isolator 1.Isolation & Interference Prevention: Enhance your audio experience with our stereo audio isolator designed to eliminate ground loop interference by isolating ground lines between input and output.
