Updates, including a new mic pre-amp and the addition of a circuit board in the delegate station, improve the sound quality of the Close-Talk IR conferencing system from Media Vision.

Media Vision USA has announced a new version of its Close-Talk wireless conference and voting system. The new Close-Talk IR conferencing system is equipped with an expandable telescopic microphone that can stretch from 12in. to 20in.

The microphone pre-amplifier is new as well, as is the circuit board in the delegate station—features that improve the sound quality of the system. The new central unit has an additional four-XLR connectivity for line in/out, as well as a tele input and output. The connectivity from the central unit to infrared transceivers has changed to standard RJ-45 sockets, making the termination much easier for contractors installing the system.

Consisting of a central unit, an optional number of delegate units, and one or more transceiver units, the Close-Talk secure wireless conference system has numerous advantages over RF and wired conferencing systems. The wireless system uses up to six infrared communications channels to transmit sound from the transceiver to delegate units, allowing multiple presenters to speak simultaneously and eliminating bugging and interference with other wireless systems. The RS-232 serial port on the central unit enables communication with a PC, as well as with control devices such as AMX and Crestron. Speakers and headphone levels in the delegate stations are adjustable.

Unlike existing RF systems, the wireless system is fully secure. It is also very competitive in price. The input/output in the central unit makes the system is ideal for teleconferencing purposes.

Other technical advantages of the Close-Talk wireless system include PC/Windows compatibility, expandable conference functionality and voting capabilities that include full speaker list control and archiving, battery-charged units that last up to 25 hours, and the ability to handle up to 256 speakers and support up to 10 transceiver units. The detachable microphones and the carrying case also make the Close-Talk conference solution ideal for rental applications.

The wireless conferencing system is now available through the existing Media Vision USA sales network across the country. To find the sales expert closest to you, visit
