4 In 4 out DSP Audio Processor

Description:
DSP-440M2+ 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.
Features:
1. With industry-leading chip ADI SHARC 21489 , the working frequency can reach 450M Hz;
2. Customizing operation software makes the confifiguration more flflexible, and it can control Different DSP.
3. Provides operation interface for customers to realize centralized control of multiple devices. And it can control third party’s equipment through DUP RS232, RS485;
4. 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;
5. Each channel has independent adaptive feedback suppression, automatically fifind the feedback point, and automatically suppress;
6. Full-featured matrix mixing, the input mixing level can be adjusted;
7. There are 16 presets, each preset works independently;
8. 8 GPIOs can independently confifigure with input or output, and they can be used as independent ADC when confifiguring with input;
9. Support channel copy, LINK and group functions;
10. Support RS232&UDP central control, UDP port can be set freely, and you can check the control software
code;
11. 2 types of wall panels are optional, and they are available to software programming.
