“
You will learn on the job, in the process of repairing many different kinds of equipment and seeing how the designers solved various problems, or failed to solve them in some cases. For every repair, you will fill out a log describing the cause of the failure and what you did to rectify it. If you don’t understand something, you may consult the more experienced Technicians, including myself.” He led the group down a wide hallway, and they crowded into a soundproofed studio. “This is the backup broadcast studio, which kept operational at all times in case of a major failure in the main studio. The first item in the signal chain is the microphone. We use dynamic mics for DJ’s and guests, and various ribbons and condensers for radio plays and orchestral broadcasts. For pre-recorded sound sources, we have direct-drive turntables, cassette decks, open-reel decks, and cart machines. All machines are wired for remote start from the console. “The consoles are vacuum tube type, fully balanced with input, output, and interstage transformers, and completely modular. They were designed in-house for absolute reliability. Channel modules can be hot-swapped without powering down the console, so that breakdowns can be fixed in a matter of seconds. “The output of the console is wired to a stereo compressor, variable mu type, to regulate the overall volume. The studio switcher selects the currently active studio and routes it to the transmitter. The output passes through an additional compressor, VCA type, with sophisticated circuitry for leveling, peak limiting, soft clipping, filtering, and pre-emphasis, in order to maximize the station’s loudness without overmodulating the transmitter.
