Question 2-Channel audio overly bass emphasized

Probably a lob foryou audio experts… I have an irritatingproblem with my newer Yamaha 867 receiver. I do have the “Sound effects” set to Straight on the receiver.

Any audio that is2-channel (no matter what input I use) the voices are overly bass emphasized. Too much of the voice is being sent to thesub. Dolby Digital quality and above audiosounds fine. What the heck could be causingthis???

Wrong/bad sub crossover. It should typically set for 80-120 hz.

This is two channel digital or analog sources when converting to multi-ch? Post your speaker setup/settings. Probably crossover but could be placement or other things going on. You ran YPAO? Did you try the official thread for your avr? The Official Yamaha RX-V867 Owners Thread

All depends on your crossover settings. If you find there is high frequencies sent to the sub, then you need to use a lower universal crossover. ie for myself in the 2 channel hifi, I use 60hz crossover on the sub, 60hz for the L/R

You use the filter on your sub as well as the avr crossover?

For the home theatre the subs own crossover is disabled. However my AV pre has a subwoofer crossover, which I set to the same as the L/C/R ie if I were to use small 80hz for L/C/R then I'd use 80hz for the subwoofer. I don't like having the subwoofer set to 120hz find it's too high frequency.

For the Hifi I'll use the subs own crossover to bring up around the L/R (so sub and L/R receive full range) or if I use a high pass between the pre and power Outlaw ICBM-1 then I disable the subs crossover, but use the selector switch on the ICBM-1.

You talking about the LPF of LFE for the subwoofer in your avr/pre-pro?

yeah Lexicon MC-8 has a LPF on subwoofer. Tried it on 120hz but don't like it. For music, if I set L/R to say 80hz, with sub LPF to 120hz then for 2 channel music sub is playing back higher frequencies than the L/R and at 120hz, too high frequency. Probable overlap /duplicated bass as well? Most obvious for music. Don't like it for movies either.

My units it only has effect on the LFE/.1 channel content so my 2ch stuff doesn't affect it. I just leave it at 120 since that's the content range of the LFE/.1 channel when there is such content anyways.

OP--sorry for the diversion while we wait for more details on your setup

You're not using the Phono input, are you?

I reran YPAO tonight... As I thought the directions in the Yamaha setup told me to set the crossover to max on the physical sub. After YPAO it is set to 90. I think I will try 60 on the receiver and see if that helps my situation.

Thanks for responses....

If YPAO adds an extreme amount of bass, try moving the sub- if it's placed in a spot where the room's response causes a null point, the low frequency .energy will be at a minimum.

Are you running it several times with the mic at different positions and averaging the response?
