Los Angeles, CA (February 19, 2015)—At the 57th annual Grammy Awards, FiberPlex’s WDM-16 fiber optic multiplexers and FOI-6010 workboxes played a role in getting music from the stage to the production truck for broadcast.
“When Mike Abbott [Grammy telecast audio coordinator] and I first spoke about what methods we were using for MADI to MADI on single-mode fiber, we decided FiberPlex was an option for the Grammys,” said Joel Singer, engineer in charge and partner, Music Mix Mobile (M3), which was responsible for mixing the live music from the stage inside the Los Angeles Staples Center to the broadcast truck outside.
FiberPlex products provided the multiplexing and conversion possible to run multiple MADI streams to and from the stage and music trucks and from the music trucks to the Denali Summit, NEP Broadcasting’s broadcast truck for delivering the live feed to CBS for broadcast.
Distribution was done in two steps, the first between the stage microphone preamps and the music trucks, and the other between the music trucks and the production truck. M3 converged signals from five racks into a WDM-16 active wavelength division multiplexer at the preamp position in the Staples Center and onto a duplex pair of single-mode fiber optics, instead of running independent TAC-4 multi-mode fiber to each rack, as had been done in previous years.
De-multiplexing of the signals was done in the music truck feeding a MADI router.
Then, to make the hop from the two music trucks to the Denali Summit truck, M3 used FiberPlex FOI-6010 workboxes to pass MADI channels between the two locations.
