Sep 18,2026
We are a professional audio enterprise integrating research and development, production, and sales. is a professional DSP Power Amplifier Module Manufacturers and DSP Power Amplifier Module Factory. For many years, we focus on the production of sound mixers, active power amplifiers, microphones, and related electronic components, equipment, and other products.
We specialize in Custom DSP Power Amplifier Module and other products, Over the years, the company has been adhering to the business policy of good products, good service, and good reputation, and has established long-term and stable cooperative relations with many companies at home and abroad, and has provided OEM services for many well-known audio brands for a long time. Customers from all walks of life are welcome to visit, guide and negotiate business. The company has professional design, production and testing teams, and can customize products according to customer needs.
DSP modules are designed based on ADAU1701 sound audio system. Signal processing includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, speaker compensation, and stereo image widening. Self-developed DSP Software offers a wide variety of signal processing algorithms integrated into an intuitive graphical user interface (GUI), allowing the creation of complicated audio signal flows. The tool can help users lower their costs by reducing development time without sacrificing quality or performance.
