AC (Alternating Current) Voltage that alternates from positive to negative in regular or irregular cycles. This type of voltage flows back to its source.4
--------------------------------------------------------------------------------
Acoustical Energy Energy consisting of fluctuation waves of pressure called sound waves.2
--------------------------------------------------------------------------------
Acoustics A science dealing with the production, effects, and transmission of sound waves through various mediums.2
------------------------------------------------------------------------------
Acid The term normally used to refer to the fluid found in a vehicle storage battery. This fluid is a somewhat diluted form of sulfuric acid. The chemical reaction between the lead of the battery's plates and the sulfuric acid creates and stores electricity. (Also see Electrolyte).2
--------------------------------------------------------------------------------
Active Arming A method for arming a security system that requires some action could include pressing a button on a remote transmitter or entering a code on a keypad.2
--------------------------------------------------------------------------------
Active Display A step-up display feature that generates animated patterns for both segment and dot matrix LCDs that proceed the sequential display of information such as clock, Custom File titles and radio station frequencies.1
--------------------------------------------------------------------------------
Active Servo Control A proprietary Sony technology for CD and MD players. A circuit which monitors tracking and focus functions, among others, and actively adjusts those functions for optimal performance.1
--------------------------------------------------------------------------------
Adaptive Reception Sony's proprietary SSIR-EX tuner technology which can actually adjust the tuner's bandwidth, depending on current reception conditions. As a result, sound quality and adjacent station interference are improved.1
--------------------------------------------------------------------------------
Adaptive Reception A circuit that provides adjustable delay such that the time at which a sound wave from various signal channels can be changed. This allows synchronization for each channel of a multi-channel output device, so sound waves from multiple speakers will arrive at the same time to a single point in space.1
--------------------------------------------------------------------------------
Air Gap The space between the top plate and the pole piece. This is where the voice coil sits.4
--------------------------------------------------------------------------------
Air Horns A type of horn that uses compressed air instead of an electric diaphragm or voice coil to produce sound. These horns are usually driven by an electric air pump that receives its trigger from a host security system.2
--------------------------------------------------------------------------------
Alarm Reset The property of an alarm system which rests the alarm to an armed state after it has sounded for a predetermined period of time. (Also see Reset).2
--------------------------------------------------------------------------------
Alarm Retriggering A condition that occurs in a security system where once it has been triggered, instead of sounding the siren for its designated time interval, it is retriggered and made to sound again.2
--------------------------------------------------------------------------------
Alternator A device that is turned by a motor to produce AC voltage, which is then rectified (turned into DC) and used to supply voltage to the vehicle's electrical system.4
--------------------------------------------------------------------------------
Alternator Whine A siren-like whining that appears when the RPMs of an engine increase. The noise is usually the result of a voltage differential created by more than one ground path or a poor ground path.2
--------------------------------------------------------------------------------
Ambience Synthesizer A unit that produces an artificial ambience pattern; one that is used to create the impression of the listener and/or performer being in a particular performance space.2
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
Amplitude The measure of how powerful sound waves are in terms of pressure.2
--------------------------------------------------------------------------------
Amplitude Modulation (AM) A method of modulation in which the amplitude of the carrier voltage is varied in proportion to the changing frequency value of an applied (audio) voltage. (Also see Frequency Modulation).2
--------------------------------------------------------------------------------
AMPS Advanced Mobile Phone Service. The cellular system used in the U.S., as well as a number of other countries.2
--------------------------------------------------------------------------------
AMS Automatic Music Search. A feature that allows a CD or cassette mechanism to skip forward or backwards to another track.1
--------------------------------------------------------------------------------
Analog An electrical signal in which the frequency and level vary continuously in direct relationship to the original acoustical sound waves. Analog may also refer to a control or circuit which continuously changes the level of a signal in a direct relationship to the control setting.2
--------------------------------------------------------------------------------
Analog Switch A hardware-oriented switch that only passes signals that are faithful analogs of transducer parameters.2
--------------------------------------------------------------------------------
Anode The electrically positive pole of an electronic device such as a semiconductor. A diode, for instance, has a positive and a negative pole; these are known as the anode and the cathode.2
--------------------------------------------------------------------------------
Antenna A mechanical device, such as a rod or wire, which picks up a received signal or radiates a transmitted signal.2
--------------------------------------------------------------------------------
Arm The term used to describe the act of causing a security system to reach a state in which it will protect the vehicle.2
--------------------------------------------------------------------------------
Arming Delay A term used to describe the elapsed time between the moment a security system is first told to arm, and when it is actually armed. This normally only applies to systems that are passively armed, but can apply to actively armed systems as well. (Also see Exit Delay).2
--------------------------------------------------------------------------------
ATA Automatic Tuner Activation. A feature that allows the tuner to be accessed while a tape deck is rewinding or fast forwarding.1
--------------------------------------------------------------------------------
ATRAC Adaptive Transform Acoustic Coding. The process used in MiniDisc that utilizes psychoacoustic principles to limit quantization noise and reduce the data quantity from 16 bits to 4 bits by using non-uniform frequency and time division.1
--------------------------------------------------------------------------------
