GLOSSARY
Some of the terms used when discussing critical communications for
television or theatre may be new to you as they are unique to intercom
applications. Although many of the terms are common to other audio
applications, to be certain you understand their meanings we offer the
following definitions:
All Call: Ability to push one button from the Main Station and talk to all
channels at once on a multiple channel system.
Ambient Noise: Those background sounds which are not part of the
specific communication but are picked up by the microphone.
Selection of a good "noise-canceling" mic will reduce ambient noise.
Belt Pack: A portable electronics package worn on the belt or
mounted on a wall or other convenient location. Interconnects to
system with mic cable and is powered by a central Power Supply or
Main Station.
Bridging, High Impedance (hi-Z): A method of connecting to an
audio line (such as Clear-Com) without loading or taking appreciable
power from that line. Simply stated, as you add more and more
stations to the line, the volume remains constant.
Call Signaling: This feature is included with the majority of
Clear-Com products. It is a visual indicator on a station (a lamp or
LED) used to attract the attention of an operator who has removed the
headset.
Channel: A channel is the line that connects parties together within a
party line - it is a two-way talk path. For example, if you have six
people who need to hear one director, you have a seven-station
single-channel need. If the same director needs to speak privately to
any one of the six, add a second channel. You now have a
seven-station, two-channel system.
Closed-Circuit: Any intercom which is connected via cable (also
called hard-wired). The other type would be Wireless. . .we make
those too. However, if you want privacy and versatility, you probably
want a closed-circuit system or a combination of both.
Cross Talk: Leakage of audio transmissions from one channel to
another.
Dry Pair: A telephone term is used to describe a pair of wires (2
conductors) that carry audio but no voltage. Contrast this with a "Wet
Pair" that carries both audio and voltage.
Duplex: Duplex refers to bi-directional communications. Normal
communication between individuals talking face to face is "full duplex"
-- in other words you can talk and listen simultaneously. The
alternative is "half-duplex" such as a push-to-talk situation where one
station at a time can talk while others listen. A walkie-talkie is a good
example of half-duplex communication.
