Wav trigger - amp output

hi! i need help about how to enable the onboard amp on a wav trigger.
by default it’s disabled, i can’t modify the .ini file using the wt initmaker app because it isn’t working on my mac.
i can modify the .ini file with a text editor but i need to know what i should write in the .ini file to enable the onboard amp. there is a reference table or something?
thank you in advance.
