Required Accessories

The WBS-670 1RU, rack-mountable base station supports up to four full-duplex wireless beltpack. The base station features a full talk/listen headset so an additional person could communicate with the intercom channel while at the base. Rear panel connections allow multiple base station/beltpack systems to operate as one large system.

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 at

Clear-Com is a closed-circuit intercom system that consistently provides high-clarity communication in high-noise and low-noise environments. A basic system consists of a single- or multi-channel power supply or main station connected to various single- or multi-channel remote stations, such as beltpacks and loudspeaker stations. Clear-Com manufactures a wide variety of both portable and fixed-installation units. All are compatible with each other. Clear-Com intercom systems can also interface with other communication systems and devices.

Please Note! This item is just one component of a larger system. Please refer to the diagram for ideas and recommendations for your Clear-Com intercom system.
