Point to point wiring, the length of wire is reduced and mutual inductance between each interference device can be reasonably avoided.
Aviation grade aluminum material, after drawing, sliver sanding, high light cutting and other multiple processes to bring quality improvement.
Both side apply sliver sanding aluminum plates to increase the weight of system and effectively suppress the noise.
Horn output set 4Ω/8Ω/16Ω selection for better match of speakers with different impedance to get best sound effect of the speaker.
Customized Line Mangetic LOGO horn terminal made from nylon + glass fiber insulation material and come with POM insulation gasket, the overall contact part using copper + inlaid with high purity carbon fiber.
Applied Japan AMRG golden foot carbon film resistor, Germany Mundorf, American MIT capacitor to improve the sound quality further.
The power transformer and output transformer are made from Nippon steel Z11 EI silicon steel sheet. The output transformer adopts the production method of 4 stack 3 to make the high and low frequencies extend and dive well.
