V

Valet A word used to describe the state in which a security system may be placed in which it would be prevented from arming passively and/or actively.2

--------------------------------------------------------------------------------

Valet Switch The switch designed to provide control to place the security system into or bring the system out of the valet state.2

--------------------------------------------------------------------------------

Variable Coefficient Digital Filter A feature which allows the user to adjust the oversampling process. Changes to the phase and impulse response can be achieved which allow fine tuning the filter to adjust for various source material, system parameters, and room acoustics.1

--------------------------------------------------------------------------------

Variable LP/HP Filter Crossover components which offer adjustable cut-off frequencies, and levels.1

--------------------------------------------------------------------------------

Variable Resistor (VR) A wire-wound resistor in which resistance can be changed to vary the amount of current or voltage that the resistor passes through the circuit .4

--------------------------------------------------------------------------------

Vas Compliance. A measurement in liters or cubic feet of the volume of air that is equal to the compliance of the speaker's total suspension.2

--------------------------------------------------------------------------------

Vented Enclosure A type of speaker enclosure with a vent (or port). The combination of: (1) the specific internal volume of air and 2) the action of the port allowing some sound waves from the enclosure's interior to pass through, enhances the speaker's response .4

--------------------------------------------------------------------------------

Voice Coil A coil of wire and the former (bobbin) around which the wire is wound. It is part of a speaker's electromagnetic motor that drives the cone to produce sound waves .4

--------------------------------------------------------------------------------

Voice Guide Confirmation A feature which provides audible confirmation of a system adjustment. Voice confirming control inputs reduces need for the driver to divert eyes from the road.3

--------------------------------------------------------------------------------

Voltage Electromotive pressure that forces current through an electrical conductor. The difference of potential between any two conductors of a circuit .4

--------------------------------------------------------------------------------

Voltage Drop The amount of energy consumed when a device has resistance in its circuit. The voltage (E) set up across a resistance (R) carrying a current (I). E=IR (Also see Volt).2

--------------------------------------------------------------------------------

Voltage-fed Antenna An antenna in which the feeder is attached to the radiator at a voltage loop. This type of antenna does not require a ground plane.2

--------------------------------------------------------------------------------

Voltage Sensing A name given to a form of alarm system trigger that relies on sensing a change in the voltage of the vehicle (Also see Current Sensing).2

--------------------------------------------------------------------------------

Volt The term used to refer to the property of electrical pressure through a circuit. The basic practical unit of difference of potential.2

--------------------------------------------------------------------------------

Volume The amount of space occupied in three dimensions (it's cubic space)-in the case of enclosures, the space inside. It can also refer to the loudness of sound .4

--------------------------------------------------------------------------------

VOM Volt-Ohm-Meter, sometimes called a Volt-Ohm-Milliammeter. A multimeter that measures voltage, ohms, and milliamperes.2

--------------------------------------------------------------------------------

VSWR Voltage Standing Wave Radio. In a standing wave system, the ratio of the voltage of the incident wave to the voltage of the reflected wave.2
