YEARNING FOR A PEACEFUL
WORLD BY SOUND !
Compared to analog power amplifier, the basic advantage of digital amplifier is energy efficient, energy saving and environmental protection, the choice of digital power amplifier can not only significantly save electricity, the production process can significantly reduce the use of aluminum, copper, steel and other metal materials, Transport 70% of the exhaust emissions.
TP4 series of digital power amplifier for my company a new generation of flagship products, the use of self-developed multi-loop control technology and modular design, with excellent technical indicators, with high reliability, power foot, sound superiority, adaptability and other advantages. Especially for low-impedance, high-current operation of the power amplifier technology, so that it has more than 95% efficiency and excellent stability; switching power supply using active PFC and soft switching technology, can adapt to the harsh power grid environment for the amplifier to provide sustained Surging power. The series has a stable and reliable 2Ω drive capability, is a high-quality mobile performance amplifier. Products have passed rigorous reliability, environmental adaptability, user experience testing.
