We are a welfare organization affiliated with SFC (Keio University Shonan Fujisawa Campus). Our main activities include managing sound equipment, providing stage sound for the school festival, supporting lectures and events in the Theta Hall (the main auditorium), and planning and producing FM radio programs. We also plan fun events on a volunteer basis. The Sound Studio is composed of three departments: PA, Theta, and FM, each with its own specific duties. The PA department lends and operates sound equipment to groups and individuals within the university, the Theta department supports lectures and events using the Theta Hall, and the FM department produces regularly broadcast radio programs. (We broadcast "KEIO BACKSTREET" every other Friday from 18:05 to 19:00 on FM 83.1MHz Radio Shonan.) The activity days and times for each department are flexible, and members can work across departments, allowing them to acquire skills at their own pace.
