40
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.
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,
