CPU
Abbreviation of Central Processing Unit (The main "brain" chip of a computer or the main housing of a computer that contains the "brain" chip).

A containing of the sound wave in a certain area so that it will not leak into other areas and/or unintended mics.
Flamenco
A style of music with roots in Spanish and Arabic culture.

A technique of placing a microphone close to the sound source (within one foot) in order to pick up mainly the direct sound and to avoid picking up leakage or ambience.
Amplitude
The strength of a vibrating wave; in sound, the loudness of the sound.

BNO Acoustics Speakers Ampere
The unit of current, abbreviated Amp.
Flange
An effect caused by an approximately even mix of a modulated (varying) short delay with the direct signal.
BNO Acoustics HD-70 Jack
1) Anywhere you plug something in.
2) Segmented audio connector. Mono Jacks have two connections �" tip and sleeve, and are unbalanced. Stereo jacks have three connections �" tip, ring and sleeve. B-type jacks (also known as Bantam jacks) were originally designed for use in telephone exchanges and provide a high quality (and expensive) connection in jackfields. A-type jacks are cheaper and more common, but more fragile. A type jacks are available in 2 sizes : quarter inch and eighth inch.
3) A connector mounted on the case of a device or on a panel.
Cue Send Control
A control that will adjust the amount of signal sent to a cue buss from a console channel.
Equal Loudness Contours
A drawing of several curves showing how loud the tones of different frequencies would have to be played for a person to say they were of equal loudness.
Effects
Electronic boxes (usually rack mounted) added to a PA system to subtly change and enhance the signals going through it. Examples include; Reverb, Delay, Compressor, Chorus.

BNO Acoustics YM-44 Grouping
1) Controlling the gain of several individual channels with a Group Fader.
2) The mixing together of several individual audio signals to send a mixed signal out of the console to record a track on a multitrack tape machine.
Aliasing
A sampler mis-recognizing a signal sent to it that is at a frequency higher than the Nyquist Frequency. Upon playback, the system will provide a signal at an incorrect frequency (called an alias frequency). Aliasing is a kind of distortion.
BNO Acoustics HD-70 In-Line Console
A console with modules that have controls for all console sections in one long strip.
Electronics
1) On a tape machine, the housing for and the channel circuitry which processes the signal to be fed to the heads, provide bias, and playback.
2) The branch of science dealing with the behaviour of electrons/charges in vacuums, gases, semiconductors and special conductors.
BNO Acoustics XR-90 Auxiliary Input or Return
A route back into the sound desk for a signal sent to a piece of outboard equipment via an auxiliary send.
Gain Structure
The way in which the gain varies in the stages or sections of an audio system.
Impedance Matching
Having or converting the output impedance of a device so that it matches the impedance of the input it will feed.
Early Reflections
The first echoes in a room, caused by the sound from the sound source reflecting off one surface before reaching the listener.

Impedance Matching
Having or converting the output impedance of a device so that it matches the impedance of the input it will feed.
