5. Line level:
The signal output of a deck or component that is usually not run through the speaker amplifier stages. Therefore the signal is much cleaner and more suitable for amplification. (e.g., The signal line level output of a good quality deck will often exceed 3 volts.)

7. Line Level
CD players, VCRs, Laserdisc Players etc., are connected in a system at line level, usually with shielded RCA type interconnects. Line level is before power amplification. In a system with separate pre-amp and power-amp the pre-amp output is line level. Many surround sound decoders and receivers have line level outputs as well.

8. Linear:
1. Referring to mechanical movement, the ability of the voice coil to move in and out in the air gap without moving side-to-side. Non-linear movement can damage the voice coil.

10. Linearity
Definition: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.

15. Load
The resistance or impedance to which energy is being supplied. In amplifiers, the speaker or speakers connected to the output of the amplifier.4

16. Lobing
Definition: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.)

21. Lossy Compression:
A type of data compression which permanently discards data that humans supposedly "cannot hear" to create much smaller audio, video and image file sizes. When the file is decompressed by the recipient, this compression method replaces the data for the sections it removed with calculated values to restore the file. The decompressed file is similar but not identical to the original file.

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
Perceived volume. Loudness can be deceiving. For example, adding distortion will make a given volume level seem louder than it actually is.

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:
Refers to radio frequencies within the 30-300 kHz band. In audio it usually refers to frequencies in the 20-160 Hz band.

27. Low Frequency Extension:
Manufacturers, writers and salespeople toss around all kinds of numbers and terminology that can be very confusing and misleading. "This $300 shoebox sized sub is flat to 20Hz". Right, in your dreams . . . How is that cheap, tiny box and driver going to reproduce a 56 foot wavelength with enough power to be heard? It will not to it. Good bass reproduction requires moving a lot of air and playback at realistic volumes. Remember the rule of needing to move four times the air to go down one octave. Example
