Save it to a registration, then you can recall it upon startup by selecting that registration. However, you may have to freeze the settings using the freeze function of the keyboard. Be sure to check the appropriate boxes before executing. You can also use the parameter lock and check Mic Setting, but when you turn the keyboard off, it will revert to factory setting. Therefore, by saving it into a registration, then activating the parameter lock after selecting the registration, it will stay in place during the entire performance until the keyboard is turned off.
Good luck,
Gary
