Thanks Peter and Lars, the links you shared were a great help. I
reached out to the person advertising and got additional information.
I also found out more about the mike I have in the panel and it is an
older model of one that is still in production. I had incorrectly
identified it as "h8 M2" it actually is "ho M2" with an umlaut over
the letter "o". The latest model on sale is "ho M5".

Now the question is which one is a better option. Anyone else has
experience with either of these microphones one way or another?
