This was a test carried out on two microphones at CS and one at EY with three DAC Box associated with these microphone. I left EX untouched because that setup is working and I am using that as a baseline to check everything else.

 My initial conclusion after looking at the power spectrum and time series plot:

1. MIC S1400302 (at CS) seems to be working with every DAC Box (named B, G and Y). This was not the case when I tested it on Monday. I only tested with DAC B and G and it worked with DAC G but not B. Fishy.

2. MIC S1400299 (at CS) seems to be little arbitrary but may be still working. This was tested with all three DAC Box.

3. MIC S1400300 (at EY) is not working with any DAC Box.

4. Also, the AA chassis that takes the microphone at CS seems to have 10X additional gain compared to EY.

The power spectrum plot and time series plot are attached for comparison.
