Marantz atskleidžia Auro-3D® patobulinimą, kuris pakels SR7009 stiprintuvą ir AV7702 procesorių į naujos kartos garso lygmenį.
"Eindhoven, October 16th, 2014 – Marantz, a leading manufacturer of premium home and personal audio products, today unveiled an upcoming upgrade offer to add breathtaking Auro-3D® sound format to their premium home theatre centres. Expected to be available beginning of December, customers can purchase a firmware upgrade that will for the first time add Auro-3D® to the recently introduced SR7009 AV Receiver and AV7702 Preamp.
By fully immersing the listener in a cocoon of life-like sound, Auro-3D® creates the sensation of actually ‘being there’. Thanks to a unique configuration of ‘Height channels’, acoustic reflections are generated and heard naturally due to the fact that sounds originate from around as well as above the listener. Depending on the size of the room, either 1 or 2 additional layers (HEIGHT and TOP – also known as “Voice of God” channel) with speakers are mounted above the existing Surround layer at ear-level to produce Auro-3D®’s defining ‘vertical Stereo field’. The height information, captured in recording or created during the mixing process, is mixed into a standard 5.1 PCM stream that comes with a regular Blu-ray or through online streaming. A Marantz AV product containing the Auro®-Codec Decoder is capable of decoding the original Auro-3D® mix."
