Subminiature Omni-directional Condenser Mic.

AT899
  • Maximum intelligibility and clean, accurate reproduction for vocalists, lecturers, stage and television talent, and worship leaders
  • Low-profile design (a mere 5 mm in diameter) is ideal for applications requiring minimum visibility
  • Includes an extensive array of accessories
  • Switchable low-frequency roll-off reduces sensitivity to popping in close vocal use
  • Available in black and beige (-TH) models
  • Operates on battery or phantom power

    The AT899 is designed to be worn as a lavalier or hidden in loose clothing or in the hair. For use as a lavalier, attach the microphone about six inches below the chin. Anticipate movements that may cause the microphone to rub against or be covered by clothing, and position the microphone to avoid it.

    The included single and double mic holders are interchangeable with all the bases. To change the holders, simply remove original holder and snap in the desired one. When using the AT899 in extremely close situations, slip the included open-pore foam windscreen over the mic to reduce wind noise or “popping.” Use the included element cover to protect the microphone element from contaminants.

    The AT899 requires 11-52V DC phantom power, or a 1.5V AA battery for operation. A battery need not be in place for phantom power operation.

    Output from the power module’s XLRM-type connector is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot” – positive acoustic pressure produces positive voltage at Pin 2.
