I like this because I want to be able to use the receiver in 2 channel mode for music along with the external amp for the subs. The problem I noticed is that once it did this it set the subs to 110hz and the fronts to large. Once I played some music on 2 channel nothing was coming from the subs. I checked all levels and all was great. I found that if I changed the fronts to smalls then the subs start to work, also if I turn on something called Extra Bass in the setup I also get the subs going. I don't remember this Extra Bass being there before? Is this an update and the correct way to have this set up? I would rather have my subs at 90hz and the fronts at Large but I do have to have the Extra Bass on? Any ideas?
OK, I can't verify all of this just now, because Christmas music is being played and I'll get shouted down if I start tinkering with it (as much as I'd like to). So, a few points:
- YPAO will set any reasonably capable speakers to large. I'm not sure what low frequency extension it's looking for, but you can simply manually set them to small afterwards. In fact, if you're using a good sub you probably want to set them to small even if they're towers (opinions differ on this).
- If the speakers are set to large, the sub output only outputs the LFE channel. 2-channel music doesn't have an LFE channel, so nothing from the subs in that case. This assumes that Extra Bass is off--see next point.
- If you engage Extra Bass, the subs will become engaged even if the speakers are set to large. What bothers some people with this is that now the speakers and the sub are reproducing the low frequencies. It could get boomy or otherwise not sound quite right. Extra Bass was probably not available before because your speakers were set to small and EB has no purpose in that case (lows already go to the sub, below the crossover).
- One advantage of setting your speakers to small is that the load for producing the low frequencies, which is demanding, is taken off of your AVR and handled by the sub(s).
- Your speaker specs should be consulted when determining your crossover. YPAO will test your speakers' capabilities, but you should check what the -3dB point of your speakers is and not set your crossover lower than that. I would suggest maybe setting it about 10 Hz above the -3 dB point (others may offer different advice here).
- If you set your speakers to small and adjust the crossover to a suitable setting, you should get bass from your sub from 2-channel music (maybe not if you're using Pure Direct, though--not sure about that just now. It may or may not override the AVR bass management, although I'm thinking not.)
Summary: I suggest you set all of your speakers to small if you have a decent sub, even if you have capable speakers. You can manually change this after running YPAO. Choose a crossover appropriate to your speakers; the one YPAO picks is probably fine, but check your speaker specs anyway. If you really like the sound from Extra Bass and your fronts set to large for 2-channel listening, you can manually change this when you want and change it back later; it won't mess up the PEQ that YPAO set up.
Enjoy your system.
