But this is the “only events” rss… How to combine article (the normale feed( whit the events rss? only one archive

yes, it’s possible but requires to add lines e.g. to your functions.php file, here’s an example

function myfeed_request($qv) {
	if (isset($qv['feed'])) $qv['post_type'] = array('event','post');
	return $qv;
}
add_filter('request', 'myfeed_request');
