ATC 51 Surround System Plays At The Prestigious Cleveland Institute Of Music

Cleveland, OH (January 10, 2007)--The Cleveland Institute of Music recently added a recital hall and an audio control room, the latter of which was designed by Dr. Peter D'Antonio, adjunct professor of acoustics at the Institute. The installed system was developed by Bruce Egre, head of the conservatory's audio recording degree program. An ATC (Acoustic Transducer Company) 5.1 surround system is part of the new sound system.

Cleveland, OH (January 10, 2007)--The Cleveland Institute of Music recently added a recital hall and an audio control room, the latter of which was designed by Dr. Peter D'Antonio, adjunct professor of acoustics at the Institute. The installed system was developed by Bruce Egre, head of the conservatory's audio recording degree program. An ATC (Acoustic Transducer Company) 5.1 surround system is part of the new sound system.
An ATC 5.1 Surround System was recently installed at the Cleveland School of Music.A number of RPG acoustical products were utilized in the design in order to minimize reflections, add absorption in specific areas, and diffuse wavefronts in others. Particular attention was paid to controlling the low-frequency response of the room. However, as D'Antonio points out, "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 low-frequency response, new Modex Plate resonators were used in all of the available dihedral wall intersections, where the pressure is high. The LF Modex Plates were used in the rear of the room and on the upper front wall areas, and then a broadband version was used directly behind the Left/Center/Right loudspeakers.

The low-end is additionally controlled by utilizing four in phase ATC SCM.1/15 subwoofers located at a quarter of the distance from adjacent walls. This placement prevents modes below the crossover from being energized. In addition to these low-frequency approaches, a four-inch deep pit roughly 6.5' x 10' was located at the first bounce position of the Left/Center/Right speakers to the listening position. The pit was filled with Modex Broadbands to control the interference caused by this floor reflection when it combines with the direct sound. The pit was covered with carpeting and the console was mounted on rails that spanned the pit. According to D'Antonio, "Every approach that is currently known has been applied to this control room with the goal of an extended and flat low-frequency response."

For the CIM multi-purpose control room, the ATC SCM150 ASL speakers were set up in a surround configuration. According to Egre, "When we conceived this as the ideal room, we felt that ATC would be an important part of that. Not only are the speakers excellent, we have received outstanding support from ATC." Additionally, another school across the street from the CIM, Case Western Reserve University, owns the smaller ATC SCM50 ASL speakers for their own recording facility, where Egre is also an instructor.
