TRIPLE-SHIELDING
Technology

Thanks to its advanced triple shielding technology, it can effectively eliminate

any interference that might affect sound quality. Electrostatic shielding

prevents high-frequency noise, electromagnetic shielding blocks environmental

EMI.Magnetic shielding further isolates the transformer, reducing its

magnetic leakage by 80% and preventing any disturbance that could affect

delicate audio signals, eliminating noise or hum in high-end devices.

They deliver flawless power for circuits, aligning with stringent EMC standards

to eliminate any possible interference and contamination at the source.
