Late last week I was very happy to execute the final changeover to RIPR's new PRODUCTION STUDIO. This is a big deal for us; our studios were originally designed and constructed by WBUR, way back in the late 1990's when they owned RIPR (then just "WRNI") outright, and most of the "back office" personnel were still located in Boston.
Accordingly, we only have one "studio". It's two connected rooms: a "control room" with the usual mix board, producer's station, director's station, etc...and a "mic booth" with just a trio of mics. The idea was that a lot of the day-to-day, off-air, production work was happening up in Boston, where WBUR had four main studios and seven edit booths. So the workload on RIPR's end would be pretty light.
Fast-forward to 2007 and now we're an independent news radio station with nine news staff and a ton of daily production needs. Yet only one studio to do it in! AAAAAHHHH!!! Scheduling conflicts were rampant.
BOO! This time on the Engineer’s Corner, we’ll talk about PHANTOM POWER. Usually not as ghoulish as one might expect, phantom power has to do with microphones. Specifically, some microphones have active circuitry inside them. That means they need power to operate, but it’s unwieldy to run a separate power cord and audio microphone cable. So a phantom circuit is used to provide DC power on the same three wires (positive/hot, negative/cold, and ground) out to the microphone that the audio from the mic also uses.
A phantom circuit is one of those nifty things in electronics that looks, to the layman, like it can’t possibly work...but it does anyway.
