Marantz® Unveils Auro-3D® Upgrade Offer for Home Theater Receiver and Preamp/Processor

Mahwah, NJ 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 theater centers. Expected to be available in December, customers can purchase a firmware upgrade that will for the first time add Auro-3D® to the recently introduced SR7009 A/V 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. A Marantz A/V product containing the Auro-Codec Decoder is capable of decoding the original Auro-3D® mix.

“Our philosophy at Marantz is to offer a sound experience just like the artist intended it to be”, said Don Freeman, vice president global marketing at D+M. “By offering the Auro-3D® upgrade to existing proud Marantz owners, we fulfill this promise by adding whole new layers of sound, and further adding value to precious Marantz gear.”

“I am really delighted that Marantz customers will be able to upgrade their AV receivers to incorporate Auro-3D®”, said Wilfried Van Baelen, founder and CEO of Galaxy Studios and Auro Technologies. “Adding the Auro-3D® Height speakers will create the most natural immersive sound experience for music and film, with High Resolution Audio in each channel. But even without adding the Height speakers, our Auro-Matic® algorithm will upmix stereo sources into an incredibly natural Surround sound experience for the home.”

The Marantz upgrade service will start beginning of December, and can easily be done by every SR7009 or AV7702 owner at home through the device’s built-in online feature upgrade function. More details to follow soon on the official Marantz website.
