WYSO 91.3 FM Turns Relocation Adversity into Opportunity
The next step was a search for potential sites and buildings that could serve as a suitable new home for WYSO, along with preparing budgets for each scenario. After extensive research, planning, and numerous reviews, the Antioch University Board approved the funds for WYSO to relocate into the former Kettering Laboratories building in Yellow Springs, OH, which was owned by the University. Supplemental funds for equipment were supplied by a grant from the Public Telecommunications Facilities Program.
Locating broadcast studios in a multi-story 60-year-old building originally designed as a research laboratory, and for which there were no plans or drawings, was especially challenging. Locations of existing load bearing walls, columns, and beams had to be considered, as well as integrating new and existing electrical and mechanical systems. Demolishing the laboratory infrastructure and mitigating unexpected hazardous materials added to the complexity and cost. We selected Miller Valentine Group as the contractor based on its experience with building other broadcast facilities, as well as its flexibility in dealing with our unique challenges.
The area designated for the studio suite had no suitable existing HVAC system, and there wasn't sufficient space for the large ductwork associated with a conventional system. The solution was a Mitsubishi City Multi system utilizing efficient heat pumps. Each studio has its own dedicated fan coil unit, which permits individual control of each room's temperature. The short duct runs are designed for high-volume, low-velocity air and incorporate noise-attenuating techniques that yield a noise criteria of only NC-20.
The new studio electrical service is conditioned for surge and EMI/RFI protection. A diesel generator supplies backup emergency power for all studio and other critical systems. An extensive common point ground system connects the building, STL tower, and ac service grounds via low impedance paths. Each studio has a reference ground connection, and every ac circuit utilizes an isolated ground outlet with its own home run ground connection. The ESD computer carpet and tile flooring are also connected to this ground system.
Lighting in the studios includes incandescent track lights and special wall illumination fluorescent fixtures on dimmers with EMI filtering and remote ballasts. Task lighting in the other operations areas uses fixtures with parabolic lenses and incorporates two different color temperature bulbs on separate switches, allowing the creative staff to alter the lighting to suit their mood.
