Features
● This series of professional amplifiers introduces advanced European technology, TD-class amplifier circuit, achieving a working efficiency of up to 89% of the whole machine, the sound quality of Class A amplifier, and saving electricity.
● The voltage-stabilized switching power supply ensures that the output power is constant in an AC 190~260V environment and will not decrease due to voltage reduction.
● The imitation car radiator made of phosphor copper, combined with the excellent direct-discharge short-distance heat conduction heat dissipation air path design, provides better heat dissipation effect.
● Industrialized production, using our own equipment: automatic placement machine, automatic plug-in machine, wave soldering machine, programmable screw machine, etc., with high consistency.

Q: How can Pro Amplifier achieve high-power output stability and system scalability through multi-channel design?
A: The professional power post-stage power amplifier (4×800W) adopts a modular multi-channel architecture. Each channel is independently equipped with a high-efficiency Class D amplifier circuit and a toroidal transformer to ensure that the power of each channel is independently output and does not interfere with each other. Through intelligent dynamic power distribution technology, the current output can be adjusted in real time according to the change of load impedance. Combined with the triple protection mechanism of overvoltage, overload and short circuit, it ensures long-term stable operation in high-power scenarios. Its multi-channel characteristics support the construction of distributed sound reinforcement systems, which can flexibly adapt to the needs of multi-region sound field coverage, such as partitioned sound reinforcement in large venues or synchronous driving of multiple sets of line array speakers, significantly improving the system scalability and deployment efficiency.
