Note:

In order to achieve an improvement in the 3-D sound when playing normal stereo sound, the decoder mode –

Panorama – must be selected.

When playing back Dolby Pro Logic Surround sound,

the decoder mode – Dolby Virtual– produces a 3- D sound similar to that of a home theatre system.

Volume level adjustment for Dolby Virtual Surround Sound and Panorama:

In order to give the sound the desired 3-D characteristics, the vol- ume of both speakers and the intensity of the surround signal should be tuned as precisely as possible to match the position of the listener (e.g. sofa). This is called "noise focusing".

To adjust the level, select the decoder mode Test.

When the arrow buttons Ÿ/ ⁄are pressed, the test signal

generator sends the noise signal (tech.: "pink noise") alternately (for approx. 3-5 seconds per pulse) as a surround signal and to the individual speakers.

Adjust the intensity of the surround signal under Level. Under Balance, arrow buttons ! / ÿ can be used to adjust the vol- ume of the relevant loudspeaker. The noise signal must sound equally loud on both channels from the listener's position.

Note:

Once saved, the basic setting only needs to be adjusted when the position of the listener or the TV setup changes.

Press the OK button to store the settings. Now select the desired decoder mode.
