Microphone instructions for UQ lecture theatres

You will need to use the UTX-B2 microphone together with the room's audiovisual system. For more information, see the Audiovisual user guide which matches the system in your room.

To use the UTX-B2K42 microphone in a UQ lecture theatre:

  1. Use the power switch to turn the device OFF.
  2. Make sure that the Mic/Line switch is set to MIC.
  3. Press and hold SET, then turn the microphone ON.
  4. Once you see characters flashing on the microphone’s display, release SET.
  5. Keep pressing SET until you see 'PO:H' or 'PO:L' flashing on the display. This is the power level setting.
  6. Use the adjustment buttons to change the power level to H, then press SET.
  7. You should see a series of numbers on the display, separated by a dot or a space. The first set of numbers should be flashing. This shows the channel the microphone is transmitting to.

    • Use the adjustment buttons again to set the room’s channel, then press SET.

    The channel for the UQ lecture theatre should be displayed on a red volume fader on the audiovisual touch-panel display, and also on a sticker above the touch panel. See Radio microphone channels for a list of UQ teaching rooms and wireless microphone channels.
