LCD: 2. Le-The inductance of a driver's voice coil, typically measured at 1 kHz in millihenries (mH). 3. Le (Measured in millihenries, mH):-The electrical inductance of a speaker's voice coil. 4. Limiter:An electronic compressor with a fixed ratio of 10 5. Line level: 6. Line level 7. Line Level 8. Linear: 9. Linear phase response: 10. Linearity:-The degree to which a given transducer or amplifier can produce an equal response within its specified range. This is usually measured in dB with +or - as small a number as possible indicating the least amount of variance from the desired flatness. 11. Line-level: 12. Line-Source:-A speaker device that is long and tall. Imagine a narrow dowel dropped flat onto the water's surface. The line-source has very limited vertical dispersion, but excellent horizontal dispersion. 13. Listening Position-A feature which can optimize frequency response and imaging for a particular position in a vehicle through the use of signal delay.1 14. Live Rock music: 15. Load 16. Lobing:-Any time more than one speaker device covers the same part of the frequency range there will be some unevenness in the output. (Picture the waves from one pebble dropped into a calm pool vs. two pebbles dropped several inches apart.) Lobing means that the primary radiation pattern(s) is at some angle above or below the centerline between the two drivers. Good crossover design takes this into account. 17. Local/distant-A switch on an FM tuner that attenuates the signal strength of very strong signals so that they don't overpower the tuner. This switch should normally be in the distant position. (e.g., Jason thought that his tuner was bad until the salesman set the local/distant switch to the distant setting.) 18. Local/distant 19. log taper:-Often used an an audio taper since its 50% rotation point has 10% resistance 20. Loss:The difference between potential energy output and actual energy output. 21. Lossy Compression: 22. Loudness:-The Sound Pressure Level of a standard sound which appears to be as loud as the unknown. Loudness level is measured in phons and equals the equivalent SPL in dB of the standard. [For example, a sound judged as loud as a 40 dB-SPL 1 kHz tone has a loudness level of 40 phons. Also, it takes 10 phons (an increase of 10 dB-SPL) to be judged twice as loud.] 23. Loudness 24. Loudness Compensation:When played quietly, this switched circuit allows fuller apparent sound from a system such that the tendancy for human hearing sensitivity to drop off at certain frequencies is compensated and the full range is heard. 25. Loudspeaker-An electro-acoustic transducer that converts electrical audio signals at its input to audible sound waves at its output. 26. Low Frequency: 27. Low Frequency Extension: 28. Low pass:-A filter that passes low frequencies and attenuates high frequencies. (e.g., We put a low pass woofer coil on John's 6 x 9-inch speaker so that it would act like a subwoofer.) 29. Low pass-A filter that passes low frequencies and attenuates high frequencies. (e.g., We put a low pass woofer coil on John's 6 x 9-inch speaker so that it would act like a subwoofer.) 30. Low Pass Filter:A network of components which attenuate all frequencies above a predetermined frequency selected by the designer. Frequencies below cut-off are passed without any effect. 31. Low Q 32. Low-Pass Filter:-A circuit that allows low frequencies to pass but rolls off the high frequencies. Most subwoofers have low-pass filters built in and many surround sound decoders have subwoofer outputs that have been low-pass filtered. 33. L-Pad-A low resistance (commonly 8 ohms) potentiometer used primarily to control the input delivered to a speaker. A remote site volume control. |
