Mike

Look at the fourth image a pr of red & blue freq resp curves, and the text with them. Can you trigger the scope (dual ch'l) on the amp out and look at the mike preamp out on the other ch'l ? Your traces show a large LF pulse followed by a smaller HF pulse, repeated 6 times.
Try to reduce the time base by 5 or 6, to show only one pr of pulses. Now turn off the HF driver. Turning the HF on/off will help iD the two pulses.
