The smallest particle which makes up a specific substance. It's composed of a center around which electrons revolve.

Headphones
Devices that can be worn on the head with small speakers that fit over the ears (or sometimes into the ears).

Brooks SS 81 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.

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.

Brooks KM 77 Attack
The rate the sound begins and increases in volume.

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.

Decibel (dB)
1) Relative measurement for the volume (loudness) of sound. Also used to measure the difference between two voltages, or two currents. See Zero dB.
2) A numerical expression of the relative loudness of a sound. The difference in decibels between two
sounds is ten times the common logarithm of the ratio of their power levels.

Ground Loop
A double grounding of a line or electronic device at two different "ground" points of differing voltage.
