In such instances, the instruction manual may not entirely match all the functions of

What is in the box?

This device has been assembled with the utmost care. If, however, an accessory is

missing, please contact your local dealer immediately.

Checking the accessories supplied:

3D Sound sonic emotion technology uses wavefield synthesis and

soundfield reproduction to eliminate the physical

dimensions of a room and transform it into a virtual

soundfield. With wavefield synthesis sonic waves are produced and dispersed

throughout the listening room ensuring localization of virtual sound sources does not

depend on or change with the listener's position. As in a natural environment real

sounds are heard from all around regardless of the device positioning.
