DSPPA D6701 - central unit of the D67 infrared conference system

DSPPA D6701 is the central unit of the D67 infrared conference system, designed for professional AV installations requiring high confidentiality, anti-eavesdropping protection, and resistance to electromagnetic interference. The system uses infrared transmission for both audio and control signals, ensuring high sound fidelity, no delay, and simplified installation without cables.

Thanks to a high-sensitivity unidirectional pickup head, the sound remains clear and precise. The proprietary data communication algorithm ensures fast system response regardless of the number of connected units. The system supports up to 255 voting units or 1000 speech units, offering flexibility for various conference scenarios.

Multiple speaking modes - FIFO, Limit, and Chairman Only - allow customized operation. Integration with an external video host enables video tracking functionality. The conference units are powered by lithium batteries with two charging options and intelligent battery management for safety and longevity.

The large LCD screen with a hierarchical menu simplifies operation, while indicators for power, signal, and frequency channel enhance usability. The metal housing of the host unit ensures durability and a professional appearance, while the conference units feature modern design using engineering plastics.
