The S-5BD has three HDMI inputs (one of which is located on the front panel) and one output.  The receiver portion has two-zone capability.  A USB port and memory card reader is also available.  The USB port allows for direct connection of an iPod.

The unit supports Dolby Pro Logic IIz, which allows for a matrixed 9.1 speaker system.  However, the unit only allows for either height channels or rear surround speakers, but not both.  Thus, 9.1 really becomes 7.1.  The multi-zone function allows one room to use 3.1 channels while still being able to use 7.1 audio in the main room.

The S-5BD uses Denon's AL24 Processing, Audyssey MultiEQ and Audyssey Dynamic Volume.  Firmware updates are available through the integrated Ethernet port.

The S-5BD is available in March 2010 for a price of $1,799.
