Product Overview
NEREUS 2000 Smart Classroom Integrated Audio Processor
NEREUS 2000 is a smart classroom integrated audio processor engineered for modern education environments. Powered by a professional 4-core DSP at 1.5 GHz, it integrates industry-leading audio preprocessing algorithms including AFC (Automatic Feedback Suppression), ANS (Automatic Noise Suppression), AEC (Acoustic Echo Cancellation), AGC (Automatic Gain Control), ARR (Automatic Reverb Reduction), steady-state and transient noise suppression, and beamforming - significantly enhancing voice amplification and interactive clarity.
Designed for K-12 and higher-education teaching spaces, NEREUS 2000 supports both local voice amplification and remote interactive scenarios. A built-in 2x150 W power amplifier module delivers clean, layered, dynamic sound, while external control buttons provide intuitive operation for teachers and IT staff.
Key Features
Powerful 4-Core DSP Platform： Professional audio processor chip with 4 cores running at 1.5 GHz provides robust computational headroom for multi-algorithm concurrent processing with ultra-low latency.
Industry-Leading Audio Algorithms
- AFC (Automatic Feedback Suppression) - ≥18 dB suppression gain
- ANS (Automatic Noise Suppression) - ≥30 dB noise reduction
- AEC (Acoustic Echo Cancellation) - ≥90 dB echo cancellation, ≥1 s tail length
- AGC (Automatic Gain Control) - ≥30 dB maximum gain
- ARR (Automatic Reverb Reduction) - ≥18 dB suppression
- Beamforming - Targeted voice capture for speaker localization
Built-in 2x150 W Power Amplifier
The integrated dual-channel amplifier module provides clear, detailed, layered sound reproduction - making voice amplification more natural and immersive in classroom spaces.
Multiple Microphone & Audio Inputs
Dedicated PRI MIC and SUB MIC ports for connection to TENDZONE UB-606 linear array microphones over Cat6 cable, plus OTH MIC inputs (for condenser or wireless microphones) and dual LINE IN for PC or wireless audio source integration.
Application Scenarios
NEREUS 2000 is purpose-built for educational environments, addressing the dual goals of national education modernization and improved teaching quality:
- K-12 smart classrooms - local voice amplification with clear, fatigue-free listening
- Higher-education lecture halls and recording classrooms - high-quality audio capture
- Remote teaching / distance education - echo-free interactive communication
- Multimedia training rooms - flexible mode switching between local and remote
- Hybrid meeting rooms - seamless integration with recording and streaming terminals
System Solution
A complete smart classroom audio solution combining the NEREUS 2000 processor with the TENDZONE UB-606 linear array microphone, passive speakers, and recording/interactive terminal. The system delivers both local amplification and remote interactive capabilities in a single integrated platform.
