Digital Signal Processors
At the core of advanced audio systems, the Digital Signal Processor (DSP) transforms raw signals into pristine sound, meticulously managing every aspect of the audio chain. Leveraging technologies like the unique AUDIO-LINK digital ring network, our DSP enables full-digital signal transmission and processing, ensuring high-fidelity sound quality through lossless transmission, high sampling rates, and broad frequency response. This empowers precise control, from individual microphone adjustments and sound field optimization to real-time echo and feedback suppression, while also supporting intelligent features like voice recognition for role separation and advanced noise cancellation for clearer recordings, ultimately delivering unparalleled clarity and control in any professional audio environment.
Features
Crystal-Clear Digital Transmission: The unique AUDIO-LINK digital ring network technology enables full-digital signal transmission and processing. A single CAT5e cable can transmit up to 64 channels of audio and other signals.
Independent Microphone Control: All microphone units support independent audio and ID output, allowing them to work with voice recognition systems for voice role separation. High-fidelity sound quality is achieved through lossless audio transmission technology, a 48K audio sampling rate, and a 20Hz ~ 20KHz frequency response.
Scalable Room Management: A single conference controller can independently control and merge four conference rooms. Multiple conference controllers can be cascaded to merge and separate larger conference rooms (Optional). The “Hand-in-Hand-Loop-Network” connection ensures the system remains fully functional, even if a discussion unit is changed or a unit malfunctions.
Precision Audio Adjustment: The sensitivity of each microphone unit and its 8-segment equalizer (EQ) can be adjusted independently. The conference controller offers a 16-segment equalized EQ for sound field adjustment, pressure limiting, and noise gate functionality that recognizes human voice. It also features AGC (automatic gain control), AFC (automatic feedback suppression), and auto-mix technology.
Optimized Zoned Audio Output: Sound output is available via separated zones, with each zone’s volume automatically adjusted based on microphone position, enabling longer-distance pickup without whistling. The system supports echo cancellation and remote two-way real-time calls with other conference controllers or third-party video conferencing terminals.
Versatile Integrated Features: Additional features include USB recording, controller monitoring, and advanced noise cancellation technology for clearer recordings. The system also provides date and time management and supports countdown speech. An optional DANTE output module is available for use with other DANTE-compatible equipment.
Powerful Speaker Support: The system can drive two 120W POE speakers, and with an extension main unit, it can support up to 16 POE speakers.
