Product Description

This digital audio processor is tailored for video conferencing, remote learning, and telemedicine applications. Equipped with 8-channel MIC/linear inputs and 8-channel linear outputs, it employs advanced algorithms, including full-band Adaptive Echo Cancellation (AEC), Adaptive Noise Suppression (ANS), Automatic Gain Control (AGC), and Auto Mixer. The result is a crystal-clear, pristine sound with a high Signal-to-Noise ratio. With a streamlined yet intelligent design, this processor requires no additional software for debugging, ensuring ease of use after installation. It is an ideal choice for project implementation and testing. Versatile in its applications, this product finds utility in various scenarios, ranging from smart system integration in small to medium-sized conference rooms, instructional recording, and distance teaching in education to court trial recording and virtual court trials in the judiciary. Additionally, it caters to surgery recording and video consultations in healthcare services and the establishment of command centers in governmental projects.
