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-wooferand the higher ranges to the other loudspeakers present in your system.

When small loudspeakers (and especially satellite speakers) are used, a sub-woofershould 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 (Ø/ ×/ Ö/ Õ / ). 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 deciBel (dB).
