DSP-88

This digital audio processor is primarily utilized for video conferencing, remote learning. It comes equipped with 8 channels of microphone and linear inputs, as well as 8 channels of linear outputs. The device processes audio signals using advanced algorithms, including full-band Adaptive Echo Cancellation (AEC), Adaptive Noise Suppression (ANS), Automatic Gain Control (AGC), and Auto Mixer, ensuring a clear, crisp sound with a high Signal-to-Noise ratio. Designed to be both compact and intelligent, the processor is suitable for use in environments where additional software support for debugging is not required.

After installation, it is ready for immediate operation, making it ideal for project implementation and testing. This product can be effectively used in various installations and applications across different industries, such as smart system integration in small to medium-sized conference rooms, instructional recording and distance learning in education, court trial recording and virtual court proceedings in the judiciary, surgical recording and video consultations in healthcare, as well as in establishing command centers for government projects.
