Telex Displays Radiocom BTR-300 Wireless VHF Intercom at AES Offers Increased Frequency Availability, More Durability and Longer Battery Life September 23, 2000 Telex Communications is displaying the RadioCom BTR-300 wireless intercom system at AES, Booth #440. The successor to Telex's BTR-200/RTS 2105 wireless VHF intercom system, the BTR-300 has been optimized for the realities of today's expanded frequency spectrum. The BTR-300 offers twice the available frequency bands of its predecessors. Improved front-end filtering allows the BTR-300 to be used in places where other wireless intercoms can't function due to interference from other transmitters. Additional filtering capabilities and channel assignments also allow a greater number of base stations and beltpacks to be used simultaneously. Up to four base stations and 16 separate beltpacks can be used at one time with the BTR-300. Advertisement The BTR-300 also incorporates improved audio circuitry for greater flexibility in connecting to a wide variety of wired intercom systems and external audio equipment. The BTR-300 is compatible with such intercom systems as RTS® TW, AudioCom, RTS ADAM and Matrix Plus. The TR-300 beltpacks have been redesigned to reinforce and strengthen key "pressure points" giving them even more "survivability" in hard use environments. Nickel Metal Hydride batteries and a plug-in charger will be available as an option. The Nickel Metal Hydride batteries will provide even longer operating time between charges and improved reliability over the more common ni-cad batteries used in other units. The TR-300 beltpacks will also be supplied with a built-in charge jack, allowing battery recharging without removing the battery pack. For more information, visit their web site at www.telex.com.
