The Cleveland Institute of Music cut the tape on its new state-of-the-art control room (a recital hall is still in the works), designed by Dr. Peter D’Antonio, adjunct professor of acoustics at the institute, while the installed system was developed by Bruce Egre, head of the conservatory’s audio recording degree program. The two new rooms were added to one of the school’s existing buildings, with the recital hall on the front and the control room in the back. Tielines from the concert hall, a small overdub room and the soon-to-be-completed recital hall feed into the control room.
According to D’Antonio, “The first challenge was to orient the room in the available space to provide a symmetrical listening environment. Following this, we used our Room Sizer program to determine the optimal dimensional ratios for uniform modal response. We also had to take into account the fact that it is an educational space and needs to accommodate more people than a typical control room. This meant that we had to be very sensitive to the amount of real estate we used for low-frequency control.”
To achieve a flat and extended LF response, Modex Plate resonators were installed in all of the available dihedral wall intersections where the pressure is high; broadband absorption is also provided with a variant of the Modex Plates, which were used in the rear of the room and on the upper-front wall areas, and then the broadband version was used directly behind the ATC SCM150 ASL L/C/R loudspeakers.
