AC. Abbreviation for alternating current.
Active crossover. Uses active devices (transistors,
IC’s, tubes) and some form of power supply to
operate.
Amplitude.
The extreme range of a signal. Usually
measured from the average to the extreme.
Arc.
The visible sparks generated by an electrical
discharge.
Bass.
The lowest frequencies of sound.
Bi-Amplification.
Uses an electronic crossover,
or line-level passive crossover, and separate
power amplifiers for the high and low frequency
loudspeaker drivers.
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.
Capacitor.
A device consisting of two or more
conducting plates separated from one another by an
insulating material and used for storing an electrical
charge. Sometimes called a condenser.
