Together with the Tempest2400, the Tempest900 offers another viable and reliable wireless intercom option for specific application needs. The Tempest900 offers much of the same intuitive operation and menu structure, as well as look and feel, of the Tempest2400 system. The difference is that the Tempest900 operates within the 900MHz frequency band. The longer wave lengths and wider symbol width in this band allow signals to break through dense walls and other structural objects more readily, increasing the range for users and reducing potential loss of audio.

The Tempest CM-922 (2-channel) BaseStation operates in the 900MHz frequency bands. The CM-922 Tempest900 BaseStations are compatible with existing 4-wire matrix or 2-wire Clear-Com, RTS or AudioCom partyline intercom systems. The LCD display makes setup easy and efficient while providing real time status of corresponding BeltStations. BaseStations* can operate in one of three modes: Normal, Shared or Split. In Normal Mode, the Tempest900 wireless system can have up to 5 wireless BeltStations per BaseStation in full duplex, simultaneous operation. Utilizing the Tempest system's TDMA technology and proprietary Accu-SyncT BaseStation coordination, up to 5 Tempest900 BaseStations and 25 Tempest full duplex wireless BeltStations can operate in close proximity while maintaining excellent system performance. Tempest900 BaseStations come fully featured with Stage Announce, Stage Relay, Auxiliary In/Out and Relay connections, Remote Mic Kill, Minimum and Maximum volume levels per BeltStation, and Wireless BeltStation Call capabilities. Battery monitoring is available at the BaseStation and through the T-Desk application. In addition, all BaseStations are provided with an Omni-Directional Whip antenna and a Remote Transceiver is available as an optional accessory.

* For BeltStations operating in Normal Mode

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. Diagram shown is a recommendation for a small production studio in a classroom environment. Also note that theTempest2400 system is shown in the diagram but theTempest900 can easily be substituted.
