ES991 Documentation

CardioidAudio-Technica ES991

Cardioid Condenser Microphone

Two microphones in one�perfect for applications requiring separate miking for PA and broadcast. The ES991 offers excellent sonic character, simple operation and streamlined appearance. One element is typically used to provide sound reinforcement while the other feeds clean audio to a broadcast network, media pool or logging recorder with no electrical interaction between the elements. The two elements can also feed audio to two separate installed systems in a church or school. The circuit grounds for each channel are completely isolated, greatly reducing the potential for hum. Each element is individually shock-mounted. 21.57” long.

  • Designed for quality sound reinforcement in demanding situations, especially those requiring separate miking for PA and broadcast
  • Dual-element configuration features completely isolated circuit grounds for each channel, greatly reducing the potential for hum
  • Fixed low-frequency roll-off (120 Hz, 12 dB/octave) and 15 dB pad
  • Dual integral windscreens ensure ultimate security against wind noise and plosives
  • Plugs directly into a 6-pin XLRF-type panel jack, or may be mounted on a standard 5/8”- 27 threaded stand using included stand clamp
  • Includes 30’ cable (6-pin XLRF-type to two 3-pin XLRM-type) for use with in-house and remote feeds
  • Small-diameter gooseneck permits highly flexible positioning while maintaining smooth, contoured appearance
