Apart from the home environment, in which the wireless reception of audio signals via infrared light has long since become a popular alternative to the corresponding radio-frequency transmission systems, this technology proves superior to all other transmission methods for certain professional applications.

This applies in particular to venues and facilities, in which the confidentiality of the information exchanged there plays a decisive role, for example in courtrooms or conference rooms, and areas in which several transmission systems are operated parallel to one another in neighbouring rooms, such as in multiplex cinemas or in living quarters within social facilities.

In addition, infrared audio transmission systems have proven very valuable in schools and universities, in large auditoriums with partial signal cover­age or in city centres where there is a very high amount of radio-frequency emissions in a multitude of frequencies.

The AUDIOropa CROSS:TALK intercom systems are for use in areas where glass partition panes or hygiene barriers are installed, and where excellent audio understanding between the communicating parties plays a central role.

Ideally suited to customer service, consultation and information service environments, the CROSS:TALK system is a perfect solution when clear communication is needed, including in bank, post office or transport counter areas, hotel receptions, medical facilities, sales or customer service counters and visiting rooms in prison facilities.

Both systems are very easy to operate and have convenient automatic functions. The internal DSP signal processing adjusts the volume accordingly to the respective meeting distance. Both systems detect ambient noise and reduce its influence on the speech signals. The efficient Class-D amplifiers ensure clear and powerful sound with high speech resolution. No further adjusting is required during the dialogue.
