The TA series professional amplifier using special circuit design techniques, focusing on the stability of the products in the long-term continuous full power conditions, the main components of the PCB board using SMT technology manufacturing, and circuit layout design through computer simulation system, so that the amplifier has a very high signal to noise ratio and anti-jamming capability. The TA series with higher damping and perfect filtering system, so that high frequency is more delicate and soft, low-frequency is more flexible.
