Input -level setting "approved DVDs"?

[Greybeard191]

The BFD guide makes sense... you find hot bass on a DVD, this drives your DVD player to a very high (max?) line out, you set sub out on HT receiver to a line out level which doesn't quite clip BFD, then set sub gain to match mains.

Question: Has anyone here gone to trouble to actually figure out which DVD(s) are hottest (line out on DVD player). I could guess at a few, but sometimes wide dynamic range can fool you and I'm wondering if some one has already nailed this down. Or does DVE or AVIA actually have tones which which drive a DVD player to max output?

thanks.

The setting of the input level of the BFD isn't exact by any means, since its input is at the mercy of where you have the volume contol on your receiver. This setup is only a trim balance to try and maximize the input. Hopefully the subwoofer adjustable trim output of the receiver when setup after a standard speaker test tone routine with the BFD bypassed will provide the correct level. If not you can increase or decrease it a bit. It may even be iterative over time when you become aware your initial setting was off somewhat.

You may have chosen a correct setting for the input, only to find the output now clips since you added (unwisely) a filter with gain. You see, if you have an input level that is just before clipping, then any filter with gain (below the crossover drop) will produce clipping. This may prompt you to reduce the input trim a bit (or listen to movies at a lower volume )

Any DVD will do that has a lot of signal that will get through the crossover. U571 will be fine - most everyone has that one. Test disks aren't apppropriate because you have no reference as to how loud you would normally play the signals as you would with a movie.

The Fellowship of the Rings scene where Sauron's head hits the ground is pretty ridiculous. Is there any DVD bass hotter that that?

Try the "Master and Commander" sea battle sequences in DTS. Amazing.
