Seat Sensor A pressure activated switch designed specifically for use in detecting any pressure applied to a vehicle's seat

-----------

Secondary The output side of a transformer

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

Second-Order The frequency attenuation that occurs at a rate of 12 dB per octave

-----------

Segmented Display An entry level display type that employs a number of elements which make up the display characters, e.g., digital clock display

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

Selectivity Tuner specification which defines the tuner's ability to reject adjacent station interference

-----------

Sensitivity The rating of a loudspeaker that indicates the level of a sound intensity that the speaker produces (in dB) at a distance of one meter when it receives one watt of input power

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

Sensor A device designed to detect or sense an intrusion or attack upon a vehicle by monitoring such things as motion, vibration, impact, sound, or the presence of a foreign mass

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

Sensor Bypass The ability of a security system to automatically or manually delete or bypass the triggers from all or some of the sensors tied into the security system

-----------

Shock Resistant Memory (SRM) See ESP

----------

Shock Sensor A sensor that is specifically designed to detect a shock or impact applied to the vehicle

----------

Short Circuit The condition that occurs when a circuit path is created between the positive and negative poles of a battery, power supply, or circuit. A short circuit will bypass any resistance in a circuit and cause it not to operate

--------

Shuffle Play A feature which employs random selection from available tracks

-----------

Signal-to Noise Ratio A ratio which indicates how much audio signal there is in relation to noise, or a specified noise floor

----------

Silicon Dampened Suspension A shock isolation system employing silicon filled shock absorbers, for increased resistance to road vibrations and othershocks

-----------

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

Siren Any device, mechanical or electronic, that is designed to produce a loud warning sound when triggered by a security system

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

Sound A type of physical kinetic energy called acoustical energy (Also see Acoustical Energy)

-----------

Sound Discriminator A device designed to listen to, evaluate, and discriminate between the sounds that may be heard within the interior of a vehicle, and then trigger the security system should the sound fit within the parameters of what the sensor is designed to react

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

Sound Pressure Level (SPL) An acoustic measurment for the ratios of sound energy. Rated in decibels (SPL dBA, SPL dBC)

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

Sound Waves Fluctuating waves of pressure that travel through a physical medium such as air. An acoustic wave consists of a traveling vibration of alternate compressions and rarefactions, whereby sound is transmitted through air or other media

-----------

Source Impedance A parameter of an audio component referring to the output impedance. A low output impedence is preferred

----------

Source Tone Memory A Custom File feature which allows the user to assign a collection of tone control settings to a particular source, such that anytime that source is selected, those tone control settings are automatically recalled

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

Spatial Sensors Devices specifically designed to detect intrusions into or around the vehicle by monitoring the space in and around the vehicle for intruders. These sensors work on a variety of different principles, including ultrasonics, radar radio frequency, or infrared

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

SPDT Single Pole Double Throw. A relay that has only one pole or contact but whose contact can throw or make electrical contact with two separate stationary contacts. This is the most commonly used relay in the mobile electronics industry

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

Spectrum Analyzer A device that displays a frequency response curve, in real time, as the curve, changes

---------

Spider A flat, round, springy device that holds the vibrating cone of a dynamic loudspeaker. The spider is where the diaphragm meets the voice coil

---------

Spontaneous Twin Drive A proprietary Sony amplifier power supply technology which employs separate voltage rails for different amplifier stages. This methods provides greater headroom and helps prevent clipping
