GLM 3.1 Loudness Calibration Issue
Answer

Hello,

I have a pair of 8330s and a 7330 sub. I am trying to set the loudness calibration but getting strange results. The caibration screen shows no problems, and plays a tone at the right volume as shown by the GLM mic. However when using the monitors at the calibrated level they are at least 10dB above what they should be calibrated to; this is verified by the GLM mic.

The monitors are fed an AES signal. I did not have this issue with GLM 3.0.

I have tried several loudness calibration settings but they all give the same result. Any thoughts?

Thanks, 

Jim
