卡达斯 COUDUS Interactive Digital Audio Processor (model TK-CLQ646) is a Lecture Capture & Recording System product from 卡达斯 COUDUS, built for meeting rooms, lecture halls, command centers and education venues. Features 6 balanced mic inputs (48V phantom) + 4 line inputs + 6 line outputs. Full-band full-duplex adaptive AEC (tail length ≥512ms, cancellation ≥70dB), adaptive noise reduction (up to 18dB), dereverberation, processing delay <8ms. USB 2.0 audio, RS-232/RJ45 control. Ideal for lecture capture, interactive classrooms, and distance conferencing.
This interactive digital audio processor is a high-performance device designed for educational lecture capture, interactive classrooms, and video conferencing. Featuring 24-bit A/D-D/A conversion with advanced audio processing algorithms. Core Audio Processing: Full-band full-duplex adaptive acoustic echo cancellation (AEC) with tail length ≥512ms, cancellation amplitude ≥70dB, and convergence speed ≥65dB/s—effectively eliminating echo in remote interactions. Full-band dynamic adaptive noise suppression (ANS) up to 18dB, significantly improving signal-to-noise ratio. Supports dereverberation with front-panel DIP switch control—delivering clear speech even in challenging acoustic environments. Processing delay <8ms ensures smooth real-time interaction. MTBF ≥60000 hours. Rich Interface Configuration: 6 balanced microphone inputs with 48V phantom power (terminal block), compatible with various condenser/dynamic microphones. 4 line inputs and 6 line outputs (terminal block) for complex system integration. 1 wireless mic input (3.5mm) and 1 headphone monitor output (3.5mm). 1 USB2.0 Type-A port supporting bidirectional audio data transmission—functions as a USB sound card. Control & Configuration: 1 RS-232 serial port for external control terminals or central control systems. 1 RJ45 port for configuration via PC. 1 RESET button for factory default restore. 1 remote debugging pairing button for remote technical support. Chassis grounding with clear grounding标识. Audio Performance: Frequency response: Mic channel +0/-2dB, Line channel +0/-0.5dB; THD+N: Mic <0.009%, Line <0.007%; Equivalent noise < -84dBu; Dynamic range >105dB; Max input level: Mic -2dBu, Line 20dBu; Max output level (balanced): 20dBu; Max gain: Mic 50dB, Line 0dB; Input impedance: Mic 2.2kΩ, Line 20kΩ; Output impedance: 400Ω.
