“They called me up because they were having some audio issues,” Wilkins relates. “They have a conference room, a multipurpose area, which consists of three divisible rooms. Two times a year they have workshops where they put the tables together in each of the rooms; they wanted a system where they could lean back in their chair and talk as normally at one table and be able to be heard at the tables on the other side of the room.”
“It was a simple enough request, yet a prior installation had badly let ACICS down. They were dealing with another company that had come in and installed ceiling microphones, just button mics. You couldn't turn the volume up a quarter-turn or it would feed back. It was completely ineffective. When I got there it wasn't even plugged in anymore,” says Wilkins, who called Tom Macri at Lienau AV Associates. “I said, they want something that's as close to the ‘magic microphone’ as they can get. Tom said, ‘Let's show them SpectraPulse.’ He brought the system down and they were blown away by it.”
Wilkins installed a SpectraPulse system incorporating 14 mtu101 Microphone Transmitter Units, the maximum quantity supported by the system, a single 14-channel drm141 Digital Receiver Module, and two seven-output aci707 Audio Control Interface demultiplexing modules. Metro AV retained the previously installed Extron ceiling speakers and Ashley amplifiers, adding AMX control panels and Biamp DSP.
Although ACICS is located just across the street from Washington, D.C.’s Union Station, the Ultra Wideband technology at the heart of SpectraPulse avoids the RF interference issues associated with conventional VHF, UHF and 2.4 GHz wireless systems. Further, since no frequency coordination is required for all 14 channels to operate simultaneously, SpectraPulse is easy to both set up and operate.
“We basically made the SpectraPulse system so that it could combine or uncombine as needed,” explains Wilkins, who configured the system such that staff members need simply set out the individual SpectraPulse microphones on the tables in the correct locations. “In order to get the best performance out of the wireless mics we set up a zone system. So we color-coded the mics and said, these only stay in room A, these in room B and these in room C.”
Founded in 1912, ACICS is the largest national accrediting organization of degree-granting institutions. ACICS accredits professional, technical and occupational programs, and is one of two national accreditors recognized by both the U.S. Department of Education and the Council for Higher Education Accreditation, with a scope that includes private post-secondary institutions offering certificates, diplomas and degrees from the Associate’s through the Master’s.
