DSPPA D6391 - 16-channel host of the translation system

DSPPA D6391 is a digital host for simultaneous translation systems, designed to support multilingual conferences requiring interpretation. It uses infrared transmission, ensuring a high level of confidentiality due to limited IR signal penetration. The system consists of a main unit (host), an IR transmitter panel, receivers, and translator desks. During conferences, translators provide real-time interpretation, and audio signals are transmitted through the host and IR transmitter, allowing participants to select the language and listen through headphones.

The device meets the international standard IEC 61603-7, ensuring compatibility with other devices compliant with this standard. Its fully digital design guarantees high sound quality and confidentiality of transmission. The host utilizes a new FPGA architecture and DQPSK modulation, ensuring stable operation. It supports a carrier frequency range of 2-6MHz, resistant to interference from high-frequency light sources. Available modes include: Normal, Recreational, and Emergency, as well as support for standard and high audio quality. The host panel is equipped with a 2.4" TFT display for monitoring system status and settings.
