difference between av preamp and av receiver

[bmurphy2121]

Radio Shack has a hand held SPL meter for under 50 bucks.Just read the small owners manual(two pages). I use it lot when

we are playing a new Bluray movie I get "InTo" it and keep turning up the volume so I use the meter to make sure I am not damaging my ears anymore then they are now. It's easy to use and just play with. Great tool for teaking each speaker for your HT system. I have learned the only dumb question is one you don't ask that cost you money.

OK thanks for the advise. I dont have a Radio Shack round me tho but now that I know the price range Ill prob just get one somewhere else.
Good advise about the questions. I just like to ask a lot of question so that I know and the answer and am not making any mistakes or loosing money making the mistakes.

As of now I do not have a SPL meter but planning on getting one any certain one I need to get?

Next dumb question since I dont have/used a SPL meter do I have to be a certain distance away from each speaker or do I just need to be where I would normally sit and then run the test?

Sorry for all the dumb question Im trying to learn on how to do this because as I have stated before Ive only used the auto calc way.

Here is one SPL meter I would get:

Yeah, just measure where you normally sit - same spot as your primary sitting position - where you place the Mic when you do the automatic calibration on the AVR.

Use C-Weight, Slow Response, Range should be 50-100dB or close to it. Each speaker and subwoofer should be 75dB (c-weight). Your sub can be 78dB if you like it a little HOT. .

When I ran Audyssey automatic room calibration on my Revel Salon 2,
Audyssey set my L/R speaker level each to -4dB, and subwoofer each to -10dB.

I had to increase the L/R channel level manually to -1dB, and subwoofer level to -3dB each.

Audyssey changed my speaker to Large, so I changed it manually to small. I kept the 80Hz. I would keep the crossover @ 80Hz.

For the Center channel, I would increase the level to 76dB-77dB for clearer dialogue.
