DSP series digital power amplifiers are our company's new generation flagship products. This series of power amplifiers adopt the multi-loop control technology independently developed by our company and have excellent technical indicators; the power conversion technology specially designed for low impedance and high current enables the power amplifier to have more than 95% efficiency and excellent stability; switching power supply Using active PFC and soft switching technology, and optimized design for the audio power amplifier, it can adapt to the harsh grid environment and provide continuous surging power for the power amplifier.

This series of digital power amplifiers are equipped with high-performance audio dedicated DSP, high-dynamic and high-precision AD/DA converter and 3.3-inch high-definition LCD display. The power amplifier can be monitored through RS-485 and LCD screen. It can receive analog audio and AES digital audio signals.

This series of power amplifiers have the characteristics of high reliability, sufficient power, outstanding sound, and strong adaptability. It has 2 varieties of 2 channels and 4 channels, stable and reliable 2Ω drive capability, which can be applied to line arrays.
