LD Systems has introduced its next generation of wireless conferencing solutions with the U500 range of 4-channel systems.
The new wireless conference sets – True Diversity systems functioning on the UHF band – are available in three versions for different frequency ranges: U505 CS 4 (554–586 MHz), U506 CS 4 (662–694 MHz) and U508 CS 4 (823–832 MHz + 863–865 MHz).
The systems include automatic channel search, automatic frequency search, infra-red frequency synchronisation of receiver and microphone unit, pilot tone and priority switching – designed for conferences and meetings. They also feature security locks and RS-232 interfaces for integration into external control systems, with an audio transmission range from 60 Hz to 16 kHz.
The U500 terminals are equipped with a gooseneck condenser microphone with hypercardioid pick-up pattern and an illuminated status ring. High-contrast OLED displays in the bases provide users with information regarding the variety of configuration options. Selectable 130Hz high-pass filters are designed to reduce proximity effects and structure-borne sound to deliver clear speech intelligibility.
The display also provides a complete overview of all functions and settings such as audio and radio signal strength and priority and the battery status of the terminals. To eliminate crosstalk, feedback and comb filter effects, the number of simultaneously live microphones can be configured on the receiver. A selectable automatic or manual gate setting and pilot tone also looks to ensure interference-free sound. The system can be expanded to include up to five cascaded U500 receivers operated in master-slave mode. As such, a maximum of 20 terminals can be used, depending on the availability of frequency ranges in the respective countries.
“The new U500-conference systems are a future-proof investment for many application areas requiring reliable wireless technology,” said Gabriel Alonso Calvillo, product manager, Integrated Systems. “Rental firms who equip company events will also benefit from our new systems. With their professional features, the U500 wireless conference sets provide effective communication and excellent speech intelligibility.
“The three available frequency ranges give users the option to select the appropriate system for their local frequency requirements,” Calvillo concluded.
