BNO Speakers Electromagnetic Theory

A statement of the principles behind electromagnetic induction: When a conductor cuts magnetic lines of force, current is induced in that conductor.

Gate
A dynamic processing device that turns a channel off or down when the signal drops below a certain level.

BNO Acoustics TS-10 Keynote Number
A number assigned to each key of a synthesizer or controller keyboard that is transmitted in the MIDI signal.

Centre Frequency
The frequency of the audio signal that is boosted or attenuated most by an equalizer with a peak equalization curve.

BNO Acoustics SQ-9 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.

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.

Format
1) The number of tracks, their width, spacing and order for tape recording.
2) To prepare a digital storage medium so that it will accept and store digital information bits.

Cancellation
A shortening of the term Phase Cancellation (the energy of one waveform significantly decreasing the energy of another waveform because of phase relationships at or close to 180 degrees).
