A 2013 expansion of the Chapel Hill Public Library in Chapel Hill, North Carolina added two meeting rooms for town hall meetings, police and fire department trainings, and – more often – miscellaneous events led by Chapel Hill organizations and citizens.
Recently, Avant Systems Integration of Raleigh, North Carolina, upgraded the sound and video systems in CHPL’s meeting rooms using Ashly Audio processing and amplification.
“The system that went in with the meeting rooms was budget-driven,” explained Scott Carneval, president of Avant Systems Integration. “The rooms are bright and fairly large, and it originally appeared to us that the existing audio and visual components were underpowered. We were subcontracted on the original install and developed a relationship with the library for maintaining the system. Feedback and inadequate volume kept recurring. When they realized there was no way to fix the original design, the library people called us in to improve the system with new components.”
Avant replaced the handful of 6.5-inch in-ceiling loudspeakers with SoundTube loudspeakers (8-inch) and subwoofers. Perhaps more importantly, they replaced the single 75W amplifier that had been dribbling into them with a new Ashly ne8250.70, which provides 250W from each of its eight channels.
A new Ashly ne24.24M Protea Matrix Processor gave Avant the ability to fully ring the system out with appropriate notches at all the frequencies that tended to feed back. A Listen Technologies assisted listening system improves the accessibility of the meeting rooms.
Avant also provided the two rooms with eight new Shure microphones: four podium mics, two handheld wireless mics, and two wireless lavalieres. Importantly, the two rooms share all eight microphones, and a BitWise iPad app allows users to select any of the eight microphones for output in either room by controlling the output logic of the Ashly ne24.24M.
Audio and video outputs are similarly matrixed to allow the smaller room to serve as overflow. “We like to stick with Ashly gear because it’s reliable, easy to use, and very well supported,” said Carneval. “Ashly’s comprehensive five-year warranty gives clients peace of mind, and Ashly’s timely delivery and solid tech support make our jobs easier and less stressful.”
“The library staff was frustrated with the old system, but they’re in love with the new system,” said Carneval. “The volume and clarity are great, and the subwoofers really add to events that need low-end punch. Moreover, they’re getting all that volume without a shred of feedback, even with eight open microphones in the room.”
