The DV-563a is hooked up to a Marantz SR 6013 receiver with Analog Cables. It uses a 5.1 Surround Sound System with a Klipsch Subwoofer.
The unit works fine with DVD Audio Discs and SACD Multichannel Disks. Only SACD 2 channel discs have the issue of no bass.
Any links that I have found for Firmware Upgrades are all dead links.
Additionally, it does not appear possible to update the settings on this unit. When trying to use the Menus on the front panel to update settings the word “GUI” is displayed. The menu display stops at that point.
Any suggestions would be appreciated.
