Fidelity
A term used to describe the accuracy of
recording, reproduction, or general quality of
audio processing. “High Fidelity” (Hi-Fi) is the
goal
of every designer.
Finalize
T
o make a DVD±R play correctly on any
WAC7500, you must nalize it. After you nalize
the
DVD±R, you cannot store or edit on it.
FM (Frequency Modulation)
In
radio broadcasting: a method of modulation
in which the frequency of the carrier voltage
is varied with the frequency of the modulation
voltage.
Frequency
The
property or condition of occurring at
frequent intervals. In sound, this simply refers
to the regular occurrence of compression and
rarication of air that we experience as sound.
Frequency Response
Is
the range of frequencies that a speaker
reproduces, lowest frequency to the highest.
While the optimal normal is 20-20,000 Hz
(Hertz), the range of human hearing for
individuals
is often much more restricted.
A good full-range speaker system however,
reproduces as much of this range as possible to
cover all variations. Individual drivers are limited
to reproduce only that part of the spectrum
for which they were made, so their response is
limited, but still a necessary point to consider
when designing a complete sound system.
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.
used again. You can erase the recording or le,
but you cannot store anything over that space.
Once the disc is full, you cannot store items on
the disc.
DVD±RW
Each time you store a recording or a le on
a
DVD±RW, the space can be re-used when
you delete it. You can re-use the same disc
repeatedly.
DVI
A
digital interface standard created by the
Digital Display Working Group (DDWG)
to
convert analog into digital signals to
accomodate both analog and digital monitors.
E
EasyLink
Philips Easylink complies to the HDMI
CEC industry standard protocal to share
functionalities between this unit and its
connected devices. This feature is only available
if you connect this unit to a HDMI compliant
device with a HDMI cable.
Eco (Eco Standby)
Eco
Standby is the most ‘economic’ mode of
the WAC7500 and consumes less than 1W. It is
‘economic’ and environmentally friendly to use
this mode during longer times of non-usage of
the WAC7500.
Encryption key
An
encryption key is an alphanumeric series
that enables data to be encrypted and then
decrypted so it can be safely shared among
members of a network.
EQ (Equalizer)
A class of electronic lter circuits designed
to
augment or adjust electronic or acoustic
systems. Equalizers can be xed or adjustable,
activ
e or passive. Many equalizers divide the
spectrum into 3 to 12 bands. This allows each
section to be either increased or decreased in
amplitude without changing the response of
the rest.
