Surrounded by the temples of Northwest Kyoto, Ritsumeikan University’s Kinugasa Campus has chosen Martin Audio CDD loudspeaker systems for two halls in its Igakukan (Institute of medical learning). The building itself contains various classrooms, common rooms and offices, as well as a cafeteria and a multipurpose hall.

CDD12 was adopted as the main loudspeaker due to its wide coverage and clear sound. Along with several Adorn ACS-55T ceiling speakers installed under the balcony on the second floor to cover the halls’ depth.

The overall aim of the wider renovation work was to provide a professional infrastructure, with Dante providing main signal routing within a Symetrix DSP environment. Touchpanel control at the side of the stage for users unfamiliar with sound system technology facilitates easy adjustment of levels and use of microphones and presentation materials. For larger events that require a more advanced approach, Dante signals are distributed to the control room, allowing professional operation via the mixer.

Since Halls 101 and 102 are connected via Dante, they can be combined, as well as share activity via video. Speakers using wireless mics can be heard equally in both halls, and communication with the hall during a web conference is possible simply by connecting a USB.

‘Because of Covid-19 we still have to maintain social distance, however I want our students to learn just as if they are present,’ says Kengo Kurashina of Ritsumeikan’s Office of Information Infrastructure, Information System Department. ‘I hope to have created those kind of conditions.

‘Martin Audio’s loudspeakers are attractive as the sound is accurate and rich. I have used them previously in another campus and succeeded in achieving the quality of sound that is usually difficult to realise in the classroom. This hall is used for a wide range of student activities such as ceremonies, academic classes, theatre, dance performance shows and traditional performing arts. Therefore, I set the goal of being able to express not only speeches, but also audio and music from the web, with overall consistency.

‘Also, since the audience needs to keep a distance, I wanted to expand the sweet spot as much as possible and so I made the decision to tune the speakers with FIR.’
