With industry-leading chip ADI SHARC 21489 , the working frequency can reach 450M Hz; Customizing operation software makes the configuration more flexible, and it can control Different DSP.
Provides operation interface for customers to realize centralized control of multiple devices. And it can control third-party’s equipment through DUP RS232, RS485; AFC (feedback suppression), AEC (echo cancellation), ANS (noise suppression), ANC (noise gain compensation), AGC (automatic gain), gain sharing, threshold automatic mixing, dodger and other processing modules;
Each channel has independent adaptive feedback suppression, automatically find the feedback point, and automatically suppress;


DMA8X8 uses the industry-leading chip ADI DSP SHARC 21489, and the highest operating frequency can reach 450M Hz.
The input and output modules of DSP can be customized according to the site conditions. At the same time, it has independent AFC/ AEC/ ANS/
AGC/ gain sharing automatic mixing, threshold automatic mixing and other processing modules. Meet the needs of audio processors and transmission in various places, such as conference rooms, multi-function halls, conference centers, auditoriums, administrative centers, etc
