Update: this information from Pioneer was incorrect. DVD (Dolby Digital 5.1 and DTS), CD and MP3 do cross over at 100 Hz and SACD does cross over at 120 Hz, but DVD-A has a crossover at 200 Hz. The 200 Hz crossover frequency can be a problem on some systems when playing DVD-A discs. A problem could exist if your sub-woofer has an amplifier with a crossover set below 200 Hz (like 160 Hz, etc.), in which case all music with frequencies between 200 Hz and the point where your sub-woofer crossover is set will be missing. To help to avoid this problem, try the following:

    If you have small speakers like those supplied with most HTIB (Home Theater In a Box) systems, you may not experience a problem as the crossover frequencies are usually quite high on these systems.

    If you have Large, full range speakers all around, consider setting them to Large and the SW to ON in the 563's setup menu. This disables the 563's crossover altogether and is generally considered to be the proper setting for these speakers.

    If you have medium sized bookshelf speakers or small surround speakers, you should check your sub-woofer amp and see if it has a switch to by-pass the built-in crossover. If it doesn't, set the crossover as high as you can.

    In all cases, you can add an external Bass Management system like the Outlaw Audio ICBM. This is a very flexible unit that takes care of all the bass management and allows you to set crossover frequencies to your liking. I'd recommend this unit regardless of your speaker size and regardless of which DVD-A / SACD player you end up buying.

    Remember, the 563's bass management system only applies to the 5.1 channel analog outputs. It is not active when using the digital outputs. In this case, your receiver handles the bass management.
