To use the pink noise on test disc or AVR for calibration?

[photographer86]

Hey everyone, as the title says. Any difference between the pink noise on the marantz sr5012 vs a test disc Spears & Munsil pink noise?

Thanks everyone as always.

My only thought, and perhaps another friend can clarify, is that to calibrate the AVR, use its own pink noise as that will be a "known quantity" to the AVR in terms of how loud it plays at X volume on the dial. If the disc is mixed high, or there is a larger than expected gain somwhere between CD and AVR, you won't actually be calibrating the AVR to anything but that particular disc.
(My Blu-Ray, and three different modes of streaming, for example, all put out different signals to my AVR. Tidal tends to be the "loudest" in terms of the signal leaving my computer and entering my AVR via Ethernet.)

Very good Ryan. I always wonder about that cause ill add to your post that my apple tv seems to little quite at the same dial position when I watch a movie streamed from apple 4k tv. But if I play a movie in my LG 4k UHD player it is a little louder. That alone makes me want to stay with the pink noise of the AVR. Thanks!

Totally agree

Always use your AVR or processor built in pink noise calibration tool for setting max volume. The more important external tool is the quality of the Spl meter used.

Thanks HT, Yup using a umm-6 calibrated microphone with REW. Figured it's little more accurate then just a amazon SPL meter. Not saying amazon not good but just the comfort lol.

All for using REW. If ever in need of a simpler solution than getting all that set up, I think the Galaxy SPL meters are highly regarded, though they tend to be a little expensive. I bought the RisePro SPL meter... good reviews and price. Haven't played with it yet.
You're on the right path!
