BNO Acoustics XR-90 Hard Disk (Hard Disc)

A storage unit for digital data that has rigid disks coated with magnetic material in a housing that includes the drive mechanism.

Binary
A numbering system based on two. In binary there are two symbols used ("l" and "0").

BNO Acoustics R-10 Link
(Said of compressors and dynamic processing units.) To combine the control input signals of two channels of a compressor (o

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.

BNO Acoustics QS-4 Feed
To send an audio or control signal to.

Error Correct
Exact replacement of lost information bits in digital audio.

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).

Headroom
1) The level difference (in dB) between normal operating level and clipping level in an amplifier or audio device.
2) A similar level difference between normal tape operating level and the level where the distortion would be 3%.
3) The difference, in decibels, between the peak and RMS levels in program material.
