Description

WBS-680 Wireless UHF Intercom

 

Like the WBS-670, the WBS-680 is a 1RU, rack-mountable base station that supports up to four full-duplex wireless beltpacks and provides a full talk/listen headset station. Rear panel connections allow the WBS-680 base station to connect to two separate channels of wired intercom; 2-wire, 4-wire or both.

Note: Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website.

IMPORTANT NOTICE:
The FCC has finished its sale of the 600 MHz frequency bands in the United States, and has set a date of July 13, 2020, for wireless intercom users to cease operation in the 617-652 MHz and 663-698 MHz frequencies.

If you are in the US and planning on purchasing a WBS system, please order the following models:
WBS-680/E88
WTR-680/E88
