Calibrating questions for 2-channel

steveinaz

Thanks to Wes I have a RS SPL meter and I've downloaded freq sweeps. My question is, with a 2-channel system what volume level do you use to get a given reference level to start from? Do you use a pink-noise sweep to set this level? What dB level should the master volume be set to?

The correction at 100 hz is +2db ...

Set master volume such that you read 83 db on the SPL for 100 hz. This will result in an adjusted reading of 85 db. Then take readings for the rest of the freqs. Enter them in the spreadsheet that has the correction factors in it and then view the chart of the adjusted numbers.
