Intelligent Digital Audio Processor DSP9275

● Built-in 24-bit A/D and D/A conversion; 32-bit DSP processor. Adopt high-speed floating-point digital audio processor and state-of-the-art Sub-Band Echo Cancellation technology to effectively eliminate echo and howling.

● Support fully automated working mode, free of manual debugging. Regardless of the change in location, temperature, humidity and decoration in the room environment, the system can be installed without the need for sound field debugging, which is accurate, reliable, and easy to use.

● With a built-in adaptive dynamic noise filter to filter out the background noise of the live environment without affecting the high-quality transmission of voice signals, improving the signal-to-noise ratio and sound quality.

● With a built-in automatic gain control (AGC) to obtain a clear and continuous voice signal.

● With built-in digital high-pass and low-pass adjustment control to limit the voice frequency response.

● With a built-in digital intelligent adjustment to improve the distance of sound pickup.

● With a built-in 10-band graphic equalizer for more accurate frequency control.

● With a built-in voice stimulation function to improve speech intelligibility.

● With automatic priority function for music and microphone in a specific channel, and automatic switching function for multi-channel microphones, the equipment can be used more flexibly and applied to more engineering application scenarios.

● With a 2.4" color display screen to display parameters and states more comprehensively and clearly, easy for debugging. All functions can be set through the machine or by connecting a computer.
