J Sound Services Utilizes Yamaha CIS For Sonic Overhaul At Iowa High School Gym

Central High School in Davenport, IA recently received a new audio system for its Marshall Gymnasium, installed by J Sound Services (JSS) of Nashville, which chose to implement Yamaha Commercial Installation Solutions (CIS) equipment as the key components in the project.

The 19,500-square-foot gym, seating approximately 2,200 in its bleacher area, needed improved speech articulation and overall coverage from an easy-to-operate system. “A major complaint to be remedied was that attendees could not understand what was being said during functions in the gymnasium,” notes Jason Spence, owner of JSS.

The new system includes 16 Yamaha VXS8 loudspeakers, a Yamaha MTX3 processor, a Yamaha XMV4280 4-channel amplifier, and a Yamaha DCP1V-4S wall mount control panel, joined by two Shure BLX4R/SM58 wireless microphones and Lowell racks and power.

The MTX3 processor manages all of the system’s I/O, acting as a mixer, providing input channel routing and processing such as gain, high-pass filters, EQ, compression, and automatic gain control, as well as output channel/speaker processing for delay, EQ, and limiting.

Two channels of wireless microphones and a stereo input from the schools media player feed four of the eight mic/line inputs of the MTX3. “We are utilizing YDIF digital audio out of the MTX3 to feed the input of the XMV4280 amplifier,” Spence says. “By doing so, we’ve streamlined our signal path to the amplifier and kept the audio digital, as opposed to using the processor or amplifiers analog I/O.

“Installing a system that is simple to operate is always an important feature when designing a system that will be operated by non-technical staff, students, and/or volunteers,” he continues. “We provided that simplicity with a Yamaha DCP1V-4S wall mount control panel, so with a touch of a button, the system is on and ready to use. By selecting the appropriate microphone on the wall controller, the microphone’s level is controlled with the volume knob on the wall controller.”

MTX processors have three wall mount control panel configurations that provide simple, remote operation of the system, and may also be controlled via free apps available for Android and Apple devices and a WAP.

“Yamaha VXS and VXC speakers have become like our Swiss Army knife of speakers; they are a great sounding, competitively priced speaker, and appropriate for numerous applications,” Spence says. “We’ve installed them with great success in houses of worship, golf courses, universities, high schools, and currently spec’d to be installed in nightclubs and restaurants this year. It was an obvious choice for Marshall Gymnasium once I determined a distributed system was the right approach for their situation.”

“The new Yamaha speakers have provided us with the opportunity to hold just about any athletic type of program we want,” states Brian Ehlinger, athletic director at the school. “Before the install, we would hold college signings, awards banquets, and season kickoff nights in the Marshall Gym and no one could understand what was being said. It got to the point where we moved those events to our auditorium instead of our historic gym.

“Now, with our new system, we can again bring our athletic functions back to the gym. This system allows us a level of intelligibility for speech that is phenomenal. We have already held a function in Marshall with our new system, and our stakeholders are very impressed.
