A standard adopted by IEC for sending and receiving digital audio based on The AES Professional Interface.
BNO Acoustics QT-5 Attenuator (Pot)
The electronic dohickey under the knobs that increases or reduces the strength of the signal running through it. When these get old and dirty, they can make popping noises or rumbles in your PA (As in "my pots are dirty").
Assign Tochoose to which place an output is going to be sent.
Binary
A numbering system based on two. In binary there are two symbols used ("l" and "0").
BNO Acoustics XR-90 Circuit
1) One complete path of electric current.
2) Similar to definition 1, but including all paths and components to accomplish one function in a device.
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.
Acoustic Echo Chamber
A room designed with very hard, non-parallel surfaces and equipped with a speaker and microphone; dry signals from the console are fed to the speaker and the microphone will have a reverberation of these signals that can be mixed in with the dry signals at the console.
Formant
An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded.

To prepare a digital storage medium (like a floppy disk) so that it will accept and store digital information bits.
BNO Acoustics R-10 Speakers Electric Instrument
Any musical instrument that puts out an electrical signal rather than an acoustic sound.
Howlback
British term for the term Feedback (the pickup of the signal out of a channel by the input of the channel or the howling sound that this produces).
BNO TS-10 Ambient Micing
Placing a microphone in the reverberant field (where the reverberation is louder than the direct sound) so as to do a separate recording of the ambience or to allow the recording engineer to change the mix of direct to reverberant sound in recording.
LFO
Low-Frequency Oscillator (an oscillator that puts out an AC signal between .1 Hz and 10Hz used for a control signal).
AES
An abbreviation of Audio Engineering Society.
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.

BNO Speakers High Impedance Cord (High Z)
A big word for instrument cable. These cords generally have quarter inch male ends. they tend to loose signal strength at lengths longer than 25 feet.
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 R-10 Chord
Three or more musical pitches sung or played together.
ID
An index signal (digital data that gives the machine information of where selections start, their selection number, etc.) on a DAT or CD.
BNO Acoustics SQ-9 Delay
Outboard sound equipment that can momentarily stores a signal being sent to part of a P.A. system so that delayed reinforced sound reaches the audience at the same time as live sound from the stage.
Compression Driver
The unit that feeds a sound pressure wave into the throat of a horn (in a horn loudspeaker).
Inverse Square Law
Simply stated, the fact that in an un-obstructed area (like an open field) the sound pressure level will drop to half-pressure (-6 dB) every time the distance to the sound source is doubled.
House Sync
A synchronization signal such as SMPTE time code that is used by all recorders in the control room.

2) In more advanced systems used in very large venues, delay can be used to time the arrival of the signal to the speakers in the back of the room so that people in the back hear the sound coming from those speakers at the same time that the sound coming from the speakers in the front of the room arrives.

A device which reduces gain when the input voltage exceeds a certain level.
Integrated Circuit (IC)
A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment.
