BNO Acoustics QT-5 Absorption
Short for the term Acoustical Absorption (quality of a surface or substance to take in, not reflect, a sound wave).

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 Speakers Far Field
The area from 3 feet away from the sound source up to the critical distance.

Audio
Most often referring to electrical signals resulting from the sound pressure wave being converted into electrical energy.

Harmonic Distortion
The presence of harmonics in the output signal of a device which were not present in the input signal.

Frequency Shift Key / FSK
The full name for FSK (A simple clock signal that can be used to run a sequencer in time with an audio tape).

BNO Acoustics GT-60 Humbucker

Pickups that are coupled together to get a certain sound.

Expander
A device that causes expansion of the audio signal.

BNO Acoustics XR-90 Frequency

Professional Interface A standard for sending and receiving digital audio adopted by the Audio Engineering Society and the European Broadcast Union.

BNO Acoustics TR-12 Full Step
A change in pitch that occurs when moving up or down two piano keys

ADAT
A trademark of Alesis Corporation designating its modular digital multitrack recording system released in early 1993.

Cable, TRS
A less common balanced cable that has 3 different contacts on its 1/4 inch connectors. Most headphone jacks are a good example of a TRS (Tip-Ring-Sleeve) connector. These are sometimes used instead of the more common XLR connection.

ADSR
The letters A, D, S &R are the first letters of: Attack, Decay, Sustain and Release. These are the various elements of volume changes in the sounding of a keyboard instrument.

BNO Speakers A/D

An abbreviation of Analog to Digital Conversion (the conversion of a quantity that has continuous changes into numbers that approximate those changes), or Analog to Digital Converter.

Error Concealment
Putting replacement information bits into a digital audio signal to replace lost bits when the digital recording or processing system cannot verify whether the lost bits were l's or 0's but can make a good guess by comparing the known bits that were close in position to the lost bits.

BNO Acoustics SQ-9 Earth
The British version of the term Ground (In electronics, a place that has zero volts).

Basic Session
The First session in recording an audio production to record the Basic Tracks.

BNO Acoustics QS-4 Amplitude
The extreme range of a signal. Usually measured from the average to the extreme.

Group
1) A number of channels or faders that can be controlled by one Master VCA slide.
2) A shortening of the term Recording Group (a buss or the signal present on a buss).

Gain Control
A device that changes the gain of an amplifier or circuit, often a knob that can be turned or a slide that can be moved up arid down.

Distorted
The way your PA sounds just before it blows up. Fuzzy and scratchy. If you hear this, it either means you have something hooked up wrong, or something in the system is going bad. It could be anything from your super expensive soundboard to a five dollar patch cord.

BNO Acoustics GT-60 Keyboard Controller

A device that has the standard music keys of piano but puts out MIDI signals

Barrier Micing
A method of placing the head of a microphone as close as possible to a reflective surface, preventing phase cancellation.

BNO Acoustics GK-3 Capacitance
That property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, measured in farads, by the ratio of the charge stored to the potential difference.

Error Concealment
Putting replacement information bits into a digital audio signal to replace lost bits when the digital recording or processing system cannot verify whether the lost bits were l's or 0's but can make a good guess by comparing the known bits that were close in position to the lost bits.

BNO Acoustics Speakers Keyboard
1) Any musical instrument controlled by pressing a key.
2) The part of the computer that has the keys.

Balanced input/output
A "balanced" connection is one that has three wires to move the signal. One is a ground, and the other two (called conductors) carry signals of equal value. This is why they are called balanced. Low Z cables and connections are the most common example.

Early Reflections
The first echoes in a room, caused by the sound from the sound source reflecting off one surface before reaching the listener.

File
A collection of digital data stored in a computer's memory bank or on a floppy disc.

BNO Acoustics SQ-9 Head

1) In tape recording, the transducer (energy converter) that changes the audio energy from electrical energy to magnetic energy and back; also the devices that apply magnetism to the recording tape for other purposes such as in the erase head.
2) The part of a device that immediately includes the transducer to change sound or audio signals from one energy form to another.

Chord
Three or more musical pitches sung or played together.

BNO Acoustics XR-90 Channels
These are divided into two separate categories. Input channels are those channels coming into the soundboard such as microphones and direct lines. Output channels are those leaving the board such as monitor and main outputs.

Auxiliary Equipment
Effects devices separate from but working with the recording console.

BNO Acoustics GK-3 Dolby
Trade name for a series of noise reduction systems that have become standard on many tape playback machines. Many film soundtracks are produced using this process. Different varieties are found from Dolby B on most personal cassette players, to Dolby SR and Digital, the current state of the art for cinema.

Fader
A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel.

Floor Toms
The large toms to the right of the drummer.

Head Amp
British name for Preamplifier (A low-noise amplifier designed to take a low-level signal, such as the output of a tape head, and bring it up to normal line level).

BNO Acoustics QT-5 kHz

An Abbreviation of kilo-Hertz.

Automation
In consoles, a feature that lets the engineer program control changes (such as fader level) so that upon playback of the multitrack recording these changes happen automatically.

BNO Acoustics YM-44 Charge
The electrical energy of electrons. The energy is in the form of a force that is considered negative and repels other like forces (other electrons) and attracts opposite (positive) forces.

Frequency
Practically speaking, high frequency means high pitch and low frequency means low pitch.

BNO Acoustics HD-70 IC
Abbreviation of Integrated Circuit (A miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment).

Infinite Repeat
A function on some delay lines that establish enough feedback so that the repeat echo will last forever, but not so much as to cause a howling sound.

Error Message
A prompt on a computer screen telling the operator that an error has occurred.

Boom Stand
A microphone stand equipped with a telescoping support arm to hold the microphone.

BNO Acoustics HD-70 Current

The amount of electron charge passing a point in a conductor per unit of time.

Balance Control
A control on a stereo amplifier that when moved clockwise will make the right channel louder (and the left channel softer) and will do the reverse when moved counter-clockwise.

A switch placed on the floor and pressed by a musician to do various functions.

Earth
The British version of the term Ground (In electronics, a place that has zero volts).

BNO Acoustics Speakers Condenser Microphone
A microphone which converts sound pressure changes into changes of capacitance. The capacitance changes are then converted into electrical voltage variations (an audio signal).

Aux Send
Short for the term Auxiliary Send (a control to adjust the level of the signal sent from the console input channel to the auxiliary equipment through the aux buss.

Frequency
The number of cycles of a waveform occurring in a second.

Expansion
The opposite of compression; for example, an expander may allow the signal to increase 2 dB every time the signal input increased by 1 dB.
