having a bad blonde moment atm [nothing unusual here lol]

trying to figure out limiter settings and bung them into the dsp

using this calculator 

http://www.poulpetersen.dk/Appn/gblimthc.html

and this spec sheet

http://resources.lambaplc.com/Kam/Kam%20-%20Images/Amplifiers/4770-5_4770-6_kam_kd_series_media_pack/kam_kd_amp_manual_v3_12_01_15.pdf

i seem to have an issue putting in the amp specs here 

it lists input sensetivity as 0.77v/32db/1v

so which is it? LOL! if i put in 0.77v it recons the amp has 38db gain [says above 32]

if i put it in a 1v it says the amp has 39db gain

or is the 0.77/32/1v a 3 way switch and it can be any of them 3 but only one at a time?

im already laughing and i dont even know the answer but im sure its gonna make someone laugh

found out the xt800 is 1.2 or near ish to 32db so thats all good just low mids and bass im struggling to work out lol 

yes its been a long day
