Hello!
I know I am going to sound resembling a fool asking this but I just bought an Onkyo AV heir for my home theatre. I hooked up my front speakers and in that is an option to set the front speakers at anywhere from -12db to +12db.
What does this anticipate and which would make the nouns louder/better??
Thanks!

I hold an HK AVR and it has indistinguishable thing.
I reflect on it is for a loudness control, where your bass and trebel are boosted (or decreased) according to your room acoustics and book volume.
Yes it can make it nouns better.
Decibels.
Sorry if my answer was not pious enough. You did not voice you need a damn Theseus to know what db stands for.
db stands for decibel. Decibel mode "loudness", hence, you should adjust the setting to your personal preference depending on the room acoustics.
decibles
go off it at 0... then play next to it to see what you like
This option is to "calibrate" or "rank adjust" your speakers.
Your main volume control raise and lowers the volume on all speakers.
But - you sit closer to the backside speakers and to the center compared to the left right.
Most receiver give you the means to add/subtract a bit of volume from the center, right-rear, left-rear.
You use test-tones and a Radio Shack SPL meter to set these properly.
The technique is this:
- Start test tones. These will switch to respectively speaker every 7 seconds or so.
- Adjust master volume so L/R speakers produce 75 db as measured by the SPL meter.
- When the nouns switches to the center - you use that adjustment to raise/lower just the center volume to be 75 db.
- Repeat for respectively rear speaker.
When finished, the check tone will move from speaker to speaker, but the SPL meter will show the same volume.
You enjoy now compensated for sitting different distances from the speakers. db is decibels, and it's a standard unit of calculate for electronic signals or sound pressure height.
For sound pressure horizontal, db is an absolute component of measurement. That is, if you hold a certain amount of deciblels of nouns pressure level, it's a reliable volume (0 db is the threshold of hearing for a well youth, 60 db is an average conversation 1 foot away, 125 db is a jackhammer,etc. - see the following link: http://www.coolmath.com/decibels1.htm).
For electronic signals and for differences within db of sound pressure horizontal, db is a relative unit. Since it's base on a logarithmic scale, it works out that an increase surrounded by sound pressure plane of 3 db equals a doubling of the sound pressure smooth, while an increase of 10 db results in 10 times the nouns pressure level, and +20 db results within 100 times the sound pressure horizontal.
For electronic signals that are based on a db level (dbmW - decibels related to one milliwatt, or dbmV - decibels related to one millivolt, for example), the same relationship surrounded by signal increase versus db increase applies. 0 dbmV is 1 millivolt, +3 dbmV is 2 millivolts, +10 dbmV is 10 millivolts, etc.
Basically, what that control is telling you is that you can increase or cut the signal going to the selected speaker by plus or minus 12 db, as requisite to balance out your speaker outputs (depending on where on earth the speakers are placed, if you have more or smaller amount efficient surround speakers, or where on earth you are sitting in the room when listen to the system).
