Tempest®2400 2-Channel Wireless Intercom System 9
Covering extremely large areas or mulple coverage locaons can be problemac with tradional wireless intercom systems.
Tempest ulizes iSelect™ on-command roaming to allow users to move from one area of coverage to another. iSelect
allows Tempest users to easily choose the desired coverage area by selecng the BaseStaon they want to communicate
through. The BeltStaon (remote) remembers the last 64 BaseStaons with which it has been Paired. When a dierent
BaseStaon is selected, the hopping paern and key code of the BeltStaon is synchronized to the selected BaseStaon
and the BeltStaon logs into the BaseStaon.
Audio latency is a crical factor in all digital systems. The hop duraon in Tempest is intenonally kept very short - under
5ms. This short hop duraon limits the amount of data that may be lost in any one hop. More importantly, it reduces system
latency, which can cause undesirable echo. Total one-way (BeltStaon to BaseStaon) system latency is less than 50ms.
Even with this short system latency, unwanted and distracng echo will occur when interfacing with hardwired party-line
intercom systems unless echo-reducon technology is implemented. Echo is primarily the result of ineciencies in the
conversion of the two-wire signal. This condion exists in analog systems as well, but it does not cause unwanted echo
because there is no system latency delay. Tempest uses advanced echo-cancellaon algorithms to eliminate this echo.
Wireless intercom systems are oen used in high-noise environments that require special design consideraon for eecve
operaon. Tempest operates extremely well even in very high ambient noise levels. This is primarily due to specic design
criteria which allow Tempest to achieve an audio dynamic range of greater than 94dB. This is more than double that of
most other digital wireless communicaon systems. This design makes Tempest ideal for use at sporng venues, concerts
and other events where unwanted noise levels are high.
Tempest oers a host of features and technology to ensure that it performs well in almost all producon environments
virtually anywhere in the world with no licensing requirements or fees.
