Capacitance - The ability of a conductor or dielectric to store electric charge.
Capacitor - 1 (polarized) An electrical circuit element used to store charge temporarily,
consisting in general of two metalic plates separated by a dielectric. 2 (non-polarized) A crossover component
used to filter out lower frequencies and allow higher frequencies to pass.
Capture Ratio - Expressed in decibels, with the smaller the number the better.
The ratio of captured signals of different strength on the same frequency.
Circuit - 1 Any closed path followed by electrical current. 2 A configuration
of electrically or electromagnetically connected components or devices.
Circuit Breaker - A device that protects electric circuits by interrupting power
in a circuit when an overload occurs. Unlike a fuse a circuit breaker is resetable.
Rated in amperes (amps).
Clipping - Audible distortion that occurs when continuous power-to-peak
power capabilities (headroom) are exceeded. "Turn it down!"
Coaxial - A speaker composed of larger cone for low range frequencies
and a smaller cone or tweeter for higher frequencies aligned on the same axis. A
crossover network is necessary to route the proper signals to each driver. These
may be passive (usually included). If the speakers are bi-amplified, an active crossover
will be used to route the proper range of frequencies to the respective amplifier channels.
Coil (Choke, Inductor) - A crossover component used to filter out higher
frequencies and allow lower frequencies to pass.
Conduction - The mode of heat transfer within a body or between bodies in contact
with each other.
Conductivity - The ability of a conductor to allow the passage of electrons,
measured in the current per unit of voltage applied, shown in resistance.
Cone - The most common shape for the ratiating surface of a loudspeaker
refered to as the part that moves the air.
Constant 12 V (+) - A lead, wire, or connection point that shows positive 12
volts regardless of ignition key position or any other switch; Positive terminal of 12 volt battery.
Continuity - The condition of being continuous.
Cross Interleave Reed-Solomon Code (CIRC) - A combination of codes and
interleaved data that make it possible to detect and correct errors in a compact disc system.
Crossover Frequencies - The frequencies at which an active or passive crossover
network divides audio signals, expressed in Hertz (Hz).
Crossover Network - A unit that divides the audio
spectrum into two or more
frequency bands. The two types are active and passive.
Crossover Point - Same as crossover frequency.
Crosstalk (Channel Separation) - The amount of interfernce on one stereo channel
caused by the leaking of the other stereo channel. The higher the rating in decibels (dB),
the better the Channel Separation.
Current - The rate of flow of electricity, measured in amperes (amps).
