XM Productions/Effanel Music handled the 5.1 surround broadcast of John Mellancamp and his band performing at Walter Reed Army Medical Center on April 27, 2007 for high-definition network HDNet. The event was held before an assembly of about 200 U.S. service personnel and their families.
The audio was mixed by Grammy Award winning mixers John Harris and Joel Singer. A digitally controlled 64-channel output preamp converted signal at the stage that was sent as MADI via fiber-optic snake to the OSR truck, where it was distributed to the digital mixing console and to two Digidesign Pro Tools systems—one for primary recording, the second for back-up. From there it went to the HDNet truck for uplink where the high-resolution signal remained completely digital.
For monitoring, XM Productions/Effanel Music chose Genelec DSP Series active monitors with AutoCal: three 8250A speakers for the L/C/R array, a pair of 8240A speakers for the left and right surrounds, and the 7260A subwoofer for LFE and bass management reproduction.
"Other systems on the market contend they have adaptive DSP calibration capability that can adjust to various listening environments, but compared to the Genelec 8200 Series, they simply fail," says Singer, the lead engineer on the project. "Other systems will look for a room node and then adjust the entire system for it; the Genelec 8200 Series speakers and the 7200 Series subwoofers have four notch filters on each speaker that can look across the bands, find the nuances in each aspect of the spectrum, and adapt each speaker individually. That is the definition of a highly adaptive system."
