I was told you want to set the sub gain till it makes the recievers sub gain +0db, but ive also heard to not turn the sub above halfway


to get my YPAO auto calibration to set the sub at 0db, I have to effectly set the sub at around 2-4oclock



is this normal?

It's not that important... You just want the end result so that the sub is balanced with the output of the other channels.

If it's not a BIG screen, it's not a theater...

This.

Don't worry too much about the "advice" you were given.

well is 3 o clock on my sub bad for it or anything, I can't really tell if its boomy as this is my first sub, unless i sit near a wall, then the bass is like 10x louder, b



Also my sub has 2 rca inputs but my receiver has 1 sub output, a rx467 reciever.


Would using a y splitter gain me any volume? I have plugged into the red mono in currently with 1 rca

So you have noticed louder bass near the walls. This is where all the fun begins! Are you sitting more in the centre of the room?

The first step in any setup is optimising speaker and listening position placement for any given room. Bad placement (like listening from the centre of the room) will force the sub to play a lot louder in order to achieve the necessary dB level from where you listen from. Doing so will create more distortion and less control.

To get a rough idea of what different placement options could do, have a play with this room and speaker calculator...

http://www.hunecke.de/en/calculators/loudspeakers.html#websites

(put in your room dimensions and select speakers and subs closest to your own)

A frequency response measurement of your room would quickly show if you have boomy bass. A large peak in the frequency response followed by a large null is what boomy bass looks like on a graph.

Imagine the benefits of better orientation of your room that gives you the low frequency dB levels with the sub at a much lower volume setting and also a frequency response that is smooth free from large peaks and dips. Bass will have tone to it where instruments will actually sound more like the real instruments. Cellos will sound like cellos and kettle drums will sound like kettle drums etc.

No, one RCA plug in is all you need.

Well i'm somewhat limited as this is mostly for movies/music/fps games on a desktop computer, so my left and right fronts are 3ft away, my subwoofer is in the left corner 6ft away, and my side surrounds are both 5ft away on the left and right a tiny bit behind me. I will try that calculator.






This is my room setup, 1 and 2 is the fronts, 3 is the sub, 4 and 5 are the surrounds which hangup on nails on the walls, and D is my dresser
