Bass Management is set in the player. Volume levels can be set in the player and the receiver. If the receiver doesn't remember speaker volume levels for each input then you should try setting them in the receiver first (for the other inputs) and then try and set the levels in the player to a satisfying level.
It's been a while since I set up a universal disc player to a receiver without BM through the multi-ch analog inputs but as I recall I set the volume levels in the player first to help off-set that low subwoofer level (-10 db) issue. I set the subs volume level to it's highest position in the player, then set the center channel to -5 and matched the fronts and surrounds to the center (with an SPL meter). This made the subwoofers volume 15 db higher then the center to start with.
After doing all that I then went into the receivers speaker setup menu and set all the levels to "0". Un-fortunately it didn't sound quite right so I reset the levels in the receiver with the SPL meter. I don't think I ever got it "just right" but it was good enough at the time. This is a totally wrong way to do it under normal circumstance but it's what I had to do to get the subwoofer level back up to a somewhat normal level.
The player was a Yamaha 6770 (same as the 750) and the receiver was an H/K 520 which remembered individual speaker volumes for each input (brilliant!) so the other inputs were not affected by M/C analog input speaker volume levels. Some newer receiver have a setting which automatically increases the subs volume level 10 db when the m/c input is selected.
A few years later I had an OPPO 83SE and an H/K 7200 which did allow for BM through the analog inputs if you so desired. They were much easier to setup and the subwoofer volume level was the same as any other input. It sounded fantastic. But, never being satisfied, I sold them and kept looking (meaning buying) for something better. Not sure I've found it yet.
If the 4001 doesn't allow for individual volume settings for each input then I'd set the levels in the receiver first and then try and reset them in the player to acceptable levels.
If someone else has a better way of doing it hopefully they will respond since I was never really happy with the outcome from the way I remember doing it (several times in several different ways).
BTW, I currently have a Marantz 7005 and also an 8002 (not in use) and the newer models (post x004) just don't sound the same. Not bad, just not the same. They changed the DSP chip between the 04's and 05's. Could be all in my head but the new ones sound like a Denon.
