Glossary Of Terms Continued...
Stereo
— Believe it or not, stereo comes from a Greek word that means solid. We use stereo or stereophony
to describe the illusion of a continuous, spacious sound field that is seemingly spread around the listener
by two or more related audio signals. In practice, stereo often is taken to simply mean two channels.
Tinnitus
— The ringing in the ears that often results from prolonged exposure to very loud sound levels.
TRS
—
Acronym for Tip-Ring-Sleeve, the three parts of a two conductor (plus shield) phone plug.
Since the plug or jack can carry two signals and a common ground, TRS connectors are often referred
to as stereo or balanced plugs or jacks.
TS
—
Acronym for Tip-Sleeve, the two parts of a single conductor (plus shield) phone plug. TS connectors
are sometimes called mono or unbalanced plugs or jacks. A ¼" TS phone plug or jack is also called a standard
phone plug or jack.
Unbalanced
—
An electrical circuit in which the two legs of the circuit do not have the identical
impedance to ground. Often one leg is also at ground potential. Unbalanced circuit connections
require only two conductors (signal “hot” and ground). Unbalanced audio circuitry is less expensive
to build, but under certain circumstances is more susceptible to noise pickup.
Volume
—
The sound level in an audio system. Perhaps the only thing that some bands have too much of.
VRMS
—
Acronym for Volts Root Mean Square. See
RMS
.
Wet
—
A signal with added reverberation or other effect like echo, delay or chorusing.
XLR Connector
— Three-pin connectors now universally used for balanced microphone connections.
Also known as Cannon, as Cannon was the original manufacturer of this type of connector. In sound work,
a Cannon connector is taken to mean a Cannon XLR-3 connector or any compatible connector. You can tell
who the audio geezers are when they refer to XLR connectors as Cannon connectors.
Z
— The electrical symbol for
impedance
.
Zymurgy
— The science of brewing, an important part of Mackie technology and history since we are
located less than one mile from the Red Hook brewery. Besides, we need something other than just a
plain ‘ol “Z” to end the glossary.
