Clear-Com Tempest 900 Reference Manual

79 Tempest®900 4-Channel Wireless Intercom System
Glossary
2-Wire or TW: A type of intercom system characterized by audio signals transmied and received on the same pair of wires
at the same me. The connector usually associated with 2-Wire or TW is a 3-pin XLR.
4-Wire: A type of intercom system characterized by audio signals transmied on one pair of wires and received on a
dierent pair of wires.
Accu-Sync: Tempest Wireless technology that synchronizes transmission ming for up to 10 BaseStaons to prevent
interference.
Auto-Null: A process that automacally opmizes the BaseStaon 2-Wire, intercom interface hybrid to match the line
characteriscs of the external 2-Wire system.
AUX IN: Inputs program or other audio sources into the Tempest BaseStaon to one or more intercom channels. The
Auxiliary IN connector is a ¼” Tip/Ring/Sleeve jack that accepts a standard ¼” TRS plug.
AUX OUT: Outputs intercom audio from one or more intercom channels to an external system. The Auxiliary OUT connector
is a ¼” Tip/Ring/Sleeve jack that accepts a standard ¼” TRS plug.
Banner: The top line of the BaseStaon display, with white-on-black leering. Usually the banner is the tle of a menu
screen.
Call Alert: A feature of intercom BeltStaons intended to visually and/or audibly alert users to a communicaon transmission.
Channel: A duplex communicaon path to transmit and receive voice communicaon.
Desensing or receiver desensizaon: Desensing occurs when a transmier is operang in close, physical proximity to a
receiver, even if that transmier is not on or near the receiver’s operang frequency.
Receiver desensizaon occurs because receivers must maintain crical voltage and current levels throughout the front-
end stages and a strong (i.e. physically close) transmier can cause these levels to vary greatly. As these levels widely
uctuate, the receiver performance will be greatly degraded. Increasing the physical distance between transmier and
receiver will decrease desensing. The greater the frequency separaon between the two, the less the receiver performance
will be aected.
Dual Listen: This BeltStaon feature permits an operator to simultaneously listen to two channels.
Frequency Hopping, Spread Spectrum (FHSS): Radio technology that ulizes many frequencies in quick succession,
intended to minimize the probability of radio frequency interference.
