Denon will offer owners of its flagship AVR-5308CI A/V Receiver and AVP-A1HDCI A/V Home Theater/MultiMedia Preamplifier the opportunity to receive a major hardware and firmware upgrade that will provide full 3D pass-through capability, as well as Audyssey MultEQ XT32, Audyssey DSX and Dolby PLIIz.

This is the 4th significant upgrade that Denon has offered to owners of its high-end products, underscoring the company's commitment to provide its customers with the very latest, most up-to-date features and capabilities. The upgrade is scheduled for October.

What the Firmware Upgrade Provides
In addition to full 3D pass-through capability, which will allow AVR-5308CI A/V and AVP-A1HDCI owners to enjoy the growing roster of 3D movies now becoming available, the firmware upgrade includes Dolby Pro Logic IIz decoding for enhanced audio experience of front height channels. For an even more dramatic surround sound experience, Denon owners will be able to take advantage of Audyssey DSX with left and right height and width channels - a new set of algorithms that pushes the envelope in audio performance by synthesizing audio signals for new surround channels based on human perception and acoustical research. The result is a reportedly much more realistic and "present" soundscape, with more audio "depth," ideal for both movies and music.

The firmware upgrade also features Audyssey's advanced MultEQ XT32 room acoustic correction system features a microphone (included) to automatically measure the speaker configuration and provide acoustic tailoring for the surround sound experience, and provides quick and easy setup. MultEQ XT32 is reportedly 32 times more accurate than the base MultEQ XT system it replaces with this upgrade.
