Audio
|
electrical signals that are involved in the reproduction or transmission of sound
|
|
|
Amplification
|
boosting of a signal to a usable level
|
|
|
Mixing
|
to combine a number of sound sources
|
|
|
Console
|
a device for amplifying, routing and mixing audio signals
|
|
|
Board
|
an audio control console
|
|
|
sound
|
the perception by the ear or by some other instrument of waves resulting from the vibration of air molecules
|
|
|
Volume
|
the level of sound, perceived as varying degrees of loudness
|
|
|
Preamplifier (preamp)
|
a small amplifier that boosts a signal, usually up to line level. It generally accomplishes the first step in the amplification process
|
|
|
Potentiometer (pot)
|
a device on an audio console that controls volume
|
|
|
Volume-unit Meter (VU-meter)
|
a device that provides a visual readout of loudness. Most important thing is to remember that zero is the refernce level to stay at or close to.
|
|
|
Monitar (Air monitors)
|
loudspeaker in a sound studio or control room
|
|
|
Amplifer
|
a device used to raise the volume or strength of a signal
|
|
|
Output
|
anything that is fed out of of an audio system
|
|
|
Deadair
|
silence over the air
|
|
|
Audition
|
a mode of console operation in which sound can be channeled into a speaker without being fed to the on-air transmitter. Also, assessing material or talent in advance of production
|
|
|
Microphone
|
a transducer that converts sound energy into an electrical signal, which may then be amplified, recorded, or broadcast.
|
|
|
Muting System
|
a device that automatically cuts the control room speaker to prevent feedback when a mic is opened.
|
|
|
Feedback
|
reamplification of a sound, resulting in a loud squel from a loudspeak; often caused by mic pickup of the output of a speak that is carrying the sound being picked up by a mic; also occurs when the record head of a tape machine receives the output signal of the same recorder.
|
|
|
Master Pot
|
the potentiometer (volume control) that governs the entire output of a console
|
|
|
Cartridge
|
the element of a turntable assembly that converts vibrations of the stylus into electical energy.
|
|
|
Submixer
|
a miniature console through which several sources can be output to one of several submasters on a full-size multichannel console
|
|
|
Patching
|
a method of changing the routing of a signal through an audio system. Also, a connection that is temporarily placed between audio inputs and outputs.
|
|
|
Routing Switcher
|
an electronic switch that can route the input and output signals. Routing switching take the place of manuel patch panels.
|
|
|
Patchcord
|
a wire with an easily inserted connection, used to reroute signals for the convience of the operator
|
|
|
Patchbay
|
a device in which patchcords are plugged for the purpose of routing signals
|
|
|
Normal Connection
|
the way in which an engineering staf routes a signal under normal circumstances. If you want to change the pattern, you can use a patchcord to "break the norm."
|
|
|
Multiple
|
a setup that allows many mics to be plugged into a sound source; useful for public events where journalists will be using tape recorders
|
