Analog audio products, technology and quality level can be compared with foreign brands, but further efforts are needed in the digital audio products. On the performance of the product, the design of the mixer and amplifier products of the major domestic manufacturers test analysis of the reasonableness of the electrical properties of technical parameters indicators as well as internal and external functions settings, the results are almost the same with the well-known foreign brand products ; and regular domestic manufacturers attached considerable importance to the quality of manufactured products, set out to run more than 8 hours aging test program has been a popular setting for keeping guard at the stability and reliability of the products run mark. In recent years, the deepening of the semiconductor industry, new materials and new technology applications, technical barriers set by foreign firms in domestic enterprises gradually fade, under favorable conditions, transistors and integrated circuits and other components used in the professional audio industry The level of quality, and also basic synchronization with foreign mainstream level.

In addition, some manufacturers of product packaging is too fragile, difficult to withstand the test of long-haul transport in, resulting in a lower pass rate of out-of-the-box, some manufacturers just blindly pursue the level of product electrical properties, and seriously neglected equipment and technology sexual importance. Usability of the major domestic manufacturers of professional audio products, generally worthy of recognition, but also the individual manufacturers cut corners on the purchase of a number of mechanical devices to compress the product cost, thus affecting the the products electrical properties fully play to the user to stay under a bad impression of the final outcome, said nearly is damaged the image of the enterprises themselves, said far is to give the wiping the domestic professional audio manufacturing industry under the small flaw.
