BNO Speakers Cycle

1) An alternation of a waveform which begins at a point, passes through the zero line, and ends at a point with the same value and moving in the same direction as the starting point.
2) On a Solid State Logic Console, a command to have the console computer control the tape machine to play and replay a certain section of the tape.

Level
Sets output volume of individual PA input channels. Usually positioned as sliders at the bottom of the soundboard.

BNO Acoustics GK-3 Input
1) The jack or physical location of where a device receives a signal.
2) The signal being received by a device.
3) The action of receiving a signal by a device.

Direct box
Used in line to convert a high impedance signal into a low impedance signal.

BNO Acoustics YM-44 Compander
1) A two section device that is used in noise reduction systems. The first section compresses the audio signal, before it is recorded, and the second section, expands the signal after recording.
2) In Yamaha brand digital consoles, a signal processing function that applies both compression and expansion to the same signal.

Keynote Number
A number assigned to each key of a synthesizer or controller keyboard that is transmitted in the MIDI signal.

Cord (Speaker, Mic, Instrument)
Used to connect a sound system together. Each type of cord is made for a specific purpose and should not be used in place of another type of cord, not even if they look alike. Also see "cable"

Diaphragm
A thin flexible membrane or cone that vibrates in response to electrical signals to produce sound waves. Distortion is usually referred to in terms of total harmonic distortion (THD) which is the percentage of unwanted harmonics of the drive signal present with the wanted signal. Generally used to mean any unwanted change introduced by the device under question.
