Glossary
Amplifier Setup Menu
In the Amplifier Setup Menu the basic settings for the
K1 AV are defined at the time the system is initially
installed. The amplifier setup menu can be opened with a
long press on the

 

button on the remote control
handset.
The Amplifier Setup Menu is supplemented by the
Amplifier Menu which contains functions which are
required more often; these include the Balance and Tone
controls. The amplifier menu is opened with a
brief
press on the     button.
Attenuator = aerial signal reducer
When picking up stations close to an unusually powerful
local station you may hear intermodulation effects
(whistling and twittering sounds). The aerial attenuator
reduces the strength of the signal received by the aerial,
and this reduces the unwanted intermodulation effects.
Bass management
The term bass management covers the division of the
frequency band into low and fairly high ranges, with the
effect that the bass signal is fed to the
sub-woofer and
the higher ranges to the other loudspeakers present in
your system.
When small loudspeakers (and especially satellite
speakers) are used, a
sub-woofer should always be
included in the system in order to ensure good bass
reproduction. The bass management feature ensures
that low-frequency sounds below the
cut-off frequency
are diverted to the sub-woofer; if allowed to reach the
SAT speakers these signals would overload them.
Cable network
During the development of the K1 AV receiver the
requirements of the European cable network were
considered to be very important. The large overload
resistance and excellent selectivity of the tuner provide
straightforward operation with cable sources, without loss
of quality.
Centre, Centre loudspeaker
The optional loudspeaker at front centre. Ideally the
Centre speaker should be set up immediately adjacent to
the television screen. For music reproduction, the Centre
fills the ‘acoustic hole’ in the centre between the stereo
loudspeakers, and provides improved spatial imaging
and localisation of sound events; this is particularly
important if the main speakers are spaced widely apart.
When a film is being played, the third speaker improves
speech localisation and assignment of the acoustic
signals relative to the picture.
Composite Video (FBAS)
A video signal in which the brightness and colour take the
form of a mixed signal which is passed along a single
cable conductor. For this reason FBAS delivers poorer
picture quality than the RGB or YUV video norms.
The
K1 AV generates pictures to the FBAS norm in
addition to RGB and YUV. However, you should only
choose this method of transmission if your television
cannot process RGB or YUV video signals.
CURSOR, cursor buttons
The cursor buttons are the ‘control buttons’ on your
remote control handset (
    /     /     /     /     ).
These buttons are used to navigate around the disc
menus on DVDs, to select files on Photo discs and MP3
discs, and to operate the
K1 AV ’s setup menus.
Cut-off frequency
The frequency below which the sound is passed to the
sub-woofer. Higher sounds are passed to the main
speakers and the
centre speaker .
The cut-off frequency of the K1 AV can be adjusted, and
should be set in the menu ‘Basic settings / Using the
system for the first time’ to suit the size of your
loudspeakers.
dB
The unit of measurement for electrical levels is the
d eci B el (dB).
