Required Accessories

Whether you are adding to a wired intercom system or creating a standalone wireless communications system, the WBS-670 and WBS-680 wireless intercoms are excellent choices. These systems extend the reach of your communications system in live
performance, studio and mobile television production, industrial and aerospace applications, or wherever full-duplex wireless communications are required.

Frequency-Agile UHF Operation:
The WBS-670 and WBS-680 operate in select frequency bands between 470-686MHz. Both wireless systems are supplied with 24 factory-selected, intermodulation-free frequencies. Select from factory presets or any suitable frequency in 25kHz increments. 720 Tx and 720 Rx frequencies can be selected, each from independent 18 MHz operational bands.

Adjustable Transmitter Power:
The beltpacks can sense when operating in close proximity to the base station and intelligently reduce transmitter output by 10dB. This effectively eliminates overloading the base station receiver front end which is the primar cause of “nearfar” densing problems. WBS wireless system beltpacks operate in normal power mode for typical distances. A manual high power setting is available when operating the beltpacks more than 200ft (160m) from the base station.

Pre-Selected Compatible:
Frequencies and Frequency Scan System setup is easy with the 24 internal pre-selected and intermodulation-free frequency groups. Aided by the “ClearScan” function, base stations and beltpacks can typically be coordinated and work together within minutes. Memory locations can be allocated so that particular sets of frequencies can be chosen, programmed and saved as a new preset.

Graphical User Interface:
A clear, backlit LCD screen displays the status of the beltpacks and provides easy access to all the powerful features as well as configuration of the operational parameters. The LCD displays which beltpack is transmitting, operating frequencies, and group/channel status.

Superior Audio Quality and Range:
The audio quality of the WBS-670 and WBS-680 wireless systems is on par with that of professional wired partyline and digital matrix intercoms. UHF frequencies are ideally suited for operating through obstacles. A variety of remote antenna options can help improve range in difficult, interference-prone production environments.

Seamless Connection to Wired Intercoms:
WBS wireless systems can interface with a variety of twowire partyline, four-wire digital matrix or other wireless intercom systems. In addition to interfacing with external intercom systems, the WBS systems provide connections for auxiliary balanced audio input and output. Wireless Talk-Around (WTA) and Stage Announce (SA) features are available on the WTR-680 beltpack.

Rechargeable Battery Option:
The battery pack will operate the beltpack in full-duplex mode for 14 hours with a set of alkaline batteries. The optional rechargeable NiMH (nickel metal hydride) batteries will give over 11 hours of continual use. The charger is available in a four-bay configuration.
