The performance studio and a few other spaces share an Audio Visual system including video projector and motorized screen, Crestron 5.1 surround sound with stereo mixdown to QSC K-series powered monitors under the control of a Lectronsonics DM series processor, Blu-Ray player, VGA/HDMI wall ports, PTZ HDMI cameras, signage and video streaming servers all to an Aurora 8x8 HDMI/HDBaseT Matrix. The outputs feed GM, conference room, lobby, reception and projector destinations. Video and song now playing are also routed to a massive ticker-style moving message sign that wraps around two sides of the studio building.

The technical operations center (TOC) sits between the performance studio and the other control rooms.

The facility has a master clock, however it is not GPS derived. Because the station carries network programming, it was felt better to receive and generate an NTP clock derived from the NPR/PRSS receiver. This clock is distributed over the networks to console, automation and wall clocks.

The studios, TOC and transmitter room share access to the building’s 480Vac/650kVA generator. The transmitter room also has an Emerson 45kVA UPS with maintenance bypass and Emerson computer room grade A/C.

What is Structured Wiring?

The term structured wiring, rather than the broadcast specific Studio Hub approach to such wiring, has been used for a reason. I am providing this detail because you may have to explain this, as did I, to third parties and we have to use their IT terms, not our broadcast terms. One has to separate the network from the node. Nodes are devices that connect to networks. Networks, and their cabling, should be agnostic to the attached devices and signals, unless there is a really good reason to do otherwise. Any competent low-voltage wiring firm can install structured wiring.

Why structured wiring? Because it works? Well, yes it does, and quite well, but that is not the reason. “But it costs more.” Not necessarily. Stepping out of the broadcast mindset, and speaking as a project manager, one has to look at the practical reality of getting things done under increasing layers of technology and regulations against tighter budgets and deadlines. You can very clearly define an scope of work, a bill of materials, a budget and sign-off criteria when you specify the number of runs of CAT-6 UTP terminated in modular ports per room. Try explaining that you need X different types of multipair, terminated in X different types of connections, and then find out you need something different, and try to purchase that difference. Anything other then CAT 5/6 UTP, or STP, or fiber, becomes a showstopper. Businesses make so much use of structured wiring now that it is the standard for wiring.
