Lesson 6. Facilities, Engineering, and Operations

Basics of the Board

  • The LION’s AudioArts D 70 on air board is a state of the art digital broadcast console
  • Each element of the studio (mic, CD player, music computer) is controlled by a “channel” on the board
  • Each channel consists of:
    • volume fader (called a pot short for potentiometer)
    • on/off buttons
    • a cue button
    • a set of buttons (output buses) controlling the destination of where the sound goes
    • an A/B switch.
  • The station uses a computer program that allows DJs to access our liners, promos, other pre produced audio, and a lot of our music – this “live assist” software is called iMediaPix.

Transmitter & EAS (Emergency Alert System) Log

  • Use Page One of the Log to sign in at the beginning of your shift and sign out at the end
  • Page Two records Meter Readings, call the WKPS transmitter and gauge its output in watts
  • Page Three is used to record the time of any EAS warnings or Amber Alerts EAS – Emergency Alert System; statewide system for weather warnings Amber Alert – State warnings issued via EAS about missing children


  • The LION’s FM signal is broadcast by a transmitter on the roof of the now former Business Administration Building (BAB), located at the NW corner of campus.
  • The audio signal produced using the studio equipment is first routed through a series of devices rack mounted in an equipment tower inside the studio (the airchain)
  • The airchain includes:
    • an Airtools digital delay that allows DJs to “dump” accidental profanity before it goes out over the air (The LION is always on a 10 second delay, except during live sports broadcasts)
    • An audio signal processor called a Compellor
  • The signal then travels from the airchain to BAB via a copper wire connection * The LION is currently petitioning Penn State to provide a more reliable/durable, high quality fiber optic cable for the studio to transmitter connection
  • An Optimod digital audio processor fine tunes the signal at the transmitter site.
  • The signal is sent out over the State College airwaves via a roof mounted antenna.
  • An antenna on the roof of Hub picks up the signal and feeds 2 different tuners via coax: 1 in the film room which feeds our webcast computers, the other our studio rack mounted Logger/Skimmer Computer to record the air feed.
  • Logger: 24/7 continuous recording, low bit rate mp3. Skimmer: higher bit rate mp3, select recording when mics are on.

Phone Lines

  • Studio Request/On air Lines: 865 9577 (WKPS)
  • Transmitter dial in: 863 1966 (don’t give out to public)
