BNO Acoustics R-10 Central Processing Unit

1) The main "brain" chip of a computer that performs the calculations and execution of instructions.
2) The main housing of a computer that contains the "brain" chip as opposed to other pieces of the computer system such as keyboards, monitors, etc.

Lead Sheet
A written chart showing the melody, lyrics and chords of a tune with full musical notation.

BNO Acoustics BP-40 Equal Loudness Contours
A drawing of several curves showing how loud the tones of different frequencies would have to be played for a person to say they were of equal loudness.

Amplifier (Power amp, Head)
It's the part of the sound system that actually magnifies or "amplifies" the sound. In other words, it makes stuff louder.

BNO Acoustics 6k-52 Clean
Describes a distortion free sound with few effects.

Bass
1) The lower range of audio frequencies up to approximately 250 Hz.
2) Short for Bass Guitar.
3) Lower end of the musical scale. In acoustics, the range (below about 200 Hz) in which there are difficulties, principally in the reproduction of sound, due to the large wavelengths involved.
4) The lower frequencies.
5) On the soundboard this should refer to the bass guitar channel, not the bass drum.
6) The lowest frequencies of sound. Bi-Amplification uses an electronic crossover or line-level amplifiers for the high and low frequency loudspeaker drivers.

Error Detection
The process of discovery that sonic information bits have been lost in digital audio.

Integrated Circuit (IC)
A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment.
