85 Tempest®24 00 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.
2xTX: Tempest Wireless proprietary technology that wirelessly transmits duplicate audio data packets from two antennas,
a frac on of a second apart and on di erent frequencies, to minimize the possibility of lost data packets.
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 belt packs 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
fl 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.
