Fairview Health Services, a network of hospitals and clinics located throughout Minnesota, recently upgraded to an Audio-Technica SpectraPulse® Ultra Wideband (UWB) Wireless Microphone System in the Heritage Room boardroom at its downtown Minneapolis headquarters. Edina, Minnesota-based systems integrator Alpha Video installed the system, which was selected for SpectraPulse’s immunity to RF spectrum congestion and, because of the personal and sensitive nature of the medical information being discussed, the high level of security that it also offers.
Alpha Video installed a system comprising 14 Audio-Technica mtu101 boundary microphone/transmitters together with a drm141 wireless digital receiver and two cei007 microphone charging stations as part of a teleconferencing set-up in the boardroom. The wireless SpectraPulse system also met the client’s requirements: to be quickly and easily reconfigured whenever the boardroom furniture is rearranged; to not interfere with the historic character of the room, which is in an early 20th century building; and to offer future upgrade potential.
SpectraPulse avoids densely congested RF spectrum by operating outside the traditional UHF frequencies occupied by wireless professional audio equipment and consumer white space devices, as well as television, medical telemetry and emergency services. SpectraPulse instead transmits in the 6-10 GHz band, which is less heavily populated, using ultra-wideband (UWB) technology, which, as a pulse-based, short range, low power level transmission method, is better able to share its spectrum without interference.
“Fairview Health Services has high standards for the systems we installed in their boardroom,” says Brian Mathison, Alpha Video Integration Specialist. “After we installed the SpectraPluse wireless microphones, we did extensive testing to make sure that the microphones would function to the customer’s expectation. They performed like a champ, passing every test. The signals got to the receivers reliably even when we were walking around, and security was not an issue.”
SpectraPulse technology offers exceptional immunity to eavesdropping, and is additionally available with optional 128-bit AES encryption, which has been approved by the National Security Agency to protect classified information. Further, the system transmits using exceedingly short, low power pulses that are very difficult to intercept.
Added Mathison, “Fairview has been extremely satisfied with the SpectraPulse microphones in the boardroom. RF interference from other sources has not been a problem, and because the transmitter is synced to the receiver, the audio comes through in a continuous, uninterrupted feed.”
Audio-Technica’s SpectraPulse UWB Wireless Microphone System, together with a wireless microphone feed from the podium, is integrated with a CobraNet-enabled Biamp AudiaFlex CM processor to form the audio core of the teleconferencing system in the boardroom, which is approximately 40 feet by 25 feet. The installed AV system also includes a Stewart Audio amplifier and eight Tannoy ceiling speakers, together with a Hitachi projector and Draper projection screen. The entire set-up is managed by a Crestron control system using a variety of Wi-Fi and touch panel interfaces.
