The text on the microphone is "Yura" which doesn't seem to find anything specific in search results. It's probably meant to be short for the artist "Yurashima", but it can also be a girl's name by itself. According to my searches "yu" can mean hot spring/water, and "ra" can either be a pluralizing suffix or refer to a location. If this is the case then maybe the TV station is all about hot springs. I'm not sure if the tiny 2 has any meaning.
