FullSound FullSound™ is an innovative technology designed by Philips. FullSound™ faithfully restores sonic details to compressed music, enhancing it to provide a full sound experience without any distortion. H Hz (Hertz) Cycles per second, named after Heinrich Hertz. I Impedance The resistance to the flow of an electric current in a circuit. This is effectively the electrical load that a loudspeaker presents to the amplifier which drives it and is measured in ohms. Input sensitivity SPL (sound pressure level) a speaker produces, given one watt of power, measured from a one-meter distance at a typical input frequency (usually 1kHz unless otherwise noted on the speaker). Interface A device or protocol which facilitates the linking of any two devices or systems; or when used as a verb ('to interface'), the process of linking. IP address An IP (Internet Protocol) address is a unique computer address that enables electronic devices to communicate with and identify each other. K Kbps Kilobits per second. A digital-data-rate measurement system which is often used with highly compressed formats such as AAC, DAB, MP3 etc. The higher the amount, the better the quality generally is. Kilo Hertz (kHz) 1000Hz or 1000 cycles per second. L LCD (Liquid Crystal Display) Probably the most common way to show visual information on non-computer electronic equipment. LivingSound LivingSound™ is a sound processing algorithm provided by Philips that offers spatial enhancements and the listener perceives the sound as though the loudspeakers were located a greater than actual distance apart from one another. Lossless compression A system for reducing the number of data bits (density) in a musical signal without corrupting the original. M M4A The audio file format used by Apple in their iTunes Music Store often appears on your system with the '.m4a' filename extension. M4A can produce better audio quality than MP3 using less physical space for the files. MHz (Mega Hertz) One million cycles per second. Mono (monaural) The operation of an amplifier in one channel for both input and output. Can refer to an amplifier with only one channel of amplification or operating in bridged mode. For low-frequency amplification applications, it provides better phase coherence and less distortion than stereo operation. 42 EN
