glossary of audIo terms
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.
