The upgrades will be available in October for the AVR-5308CI A/V receiver and AVP-A1HDCI preamp-processor at pricing that hasn't been set. The upgrades consist of hardware and firmware upgrades that will be installed by Denon's factory service centers.
The updates mark the fourth major retrofit upgrade that Denon has launched for its high-end products and signifies the company's commitment "to ensuring that our customers are â€˜future ready' and remain at the leading edge of all the latest performance-enhancing technologies," said Jeff Talmadge, product development and systems integration director.
Pro Logic IIz post-processing adds front-height channels to a surround system. Audyssey DSX adds left and right height and width channels. Audyssey's MultEQ XT32 room acoustic correction system automatically tailors response to compensate for a room's acoustics. It's promoted as 32 times more accurate than the base MultEQ XT system that it replaces in the original products.
