Broom RM 909 Audio

Most often referring to electrical signals resulting from the sound pressure wave being converted into electrical energy.

Active Crossover
Uses active devices (transistors, IC's, tubes) and some form of power supply to operate.

Brooks QS - 95 Electrostatic Charge
The excess or deficiency of electrons in a given area.

Feedback
1) The delayed signal sent back to the input of a delay line, used in repeat-echo effects.
2) The pickup of the signal out of a channel by its input or the howling sound that this produces.
3) In an amplifier, the phase reversed output signal sent back to its input, reducing gain but also distortion and noise.
4) This occurs when the sound coming out of the speakers goes back into the microphones, then back out the speakers, then back into the mics…and so on. This can build very quickly to a point where everyone in the room is holding their ears and screaming at you. It can also cause damage to the PA.

Beats Per Minute BPM
The number of steady even pulses in music occurring in one minute and there fore defining the tempo of the song.

Information Bits
The bits in the digital signal that make up actual values or commands being communicated as opposed to bits that are used for checking & correcting data or other purposes.

Capacitance
That property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, measured in farads, by the ratio of the charge stored to the potential difference.
