Dalian Daquanding Group launched a 2.1CH audio amplifier solution based on Qualcomm products

The QCS400 family is a single-chip architecture that not only integrates Qualcomm’s high-performance processor, artificial intelligence engine, connectivity, multiple advanced audio and visual Display functions, but also optimizes for low power consumption. Compared with the previous generation SoC series, the QCS400 SoC series can bring smart speaker users a more powerful voice assistant experience through a faster and smarter voice UI, and users can have a good experience even in noisy environments.

On September 2, 2021, Dalian General Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its subsidiary Quanding launched a 2.1CH audio amplifier solution based on the Qualcomm (Qualcomm) QCS400 family.
