IC 7300 preamp gain?

[VK5TM]

Does anyone know what the preamp gain is in the IC 7300?
I have Googled but to no avail.
The manuals have no info that I can find.
Thanks in advance.

I saw pre-amp 1 listed as 7dB in a review on AB4OJ's website with pre-amp 2 only mentioned as being higher.

Likewise, my searching the net didn't find anything else useful, maybe a call to Icom is in order.
