Hey all, Before I get my new M60’s, I wanted to make sure I understood how to use this thing properly. The below is instructions were taken from Audioholics: Quote:
“Place the SPL Meter at the listening position at ear level with the Mic end pointed toward the ceiling. Select “C” weighting, response slow then, turn the dB dial to 70. Activate the internal pink noise generator of your Receiver and select manual test tone. Now adjust each speaker to +75 dB reference. When you are adjusting the surrounds make sure your body is not in a direct path of the speaker and make sure the house is quiet. When doing the calibration, only the test tone should be heard (A/C, ceiling fans, ect. should be turned off). I like to adjust the subwoofer level to + 80dB for wow effect. Your taste may vary.”
What I don’t understand is the +75dB. My receiver (Pioneer ELITE) only goes to +12. What am I missing?
Thanks

OK, ignore the volume settings on your receiver. It's talking about the reading of 75 dB on the meter.

So where should I set my receiver to test? My reference level is between -10 and -5 on my receiver.

Robot,
Set up the meter and then turn the volume up on the reciever so that the left front speaker registers 75 db on the meter...Disregard where the volume control on the reciever is set.
Hope this helps.

Thanks, WhatFurrer.
Sory for my ignorance, but it doesn't say "75dB" on the meter (I have the analog version).
It reads from -10 to +6.

Ah. You set the meter to 70 dB (or 80 dB) and read it at +5 (or -5)

Does your receiver have auto setup with a mic? If so, run that first, that is what I do. Then I go back and check with an SPL meter to make sure that the speakers are the same on the meter. I've heard the starting with the left speaker thing first, but I don't think that matters with the newer receivers.

The THX reference level for movies is 85db I think once you get your meter out and start adjusting the volume to 85db with pink noise you'll find its TOO LOUD! At least, I did.

It does, but I never agree with it.
