Manufacturer's website

The U873R UniPoint hypercardioid condenser microphone offers smooth, accurate audio reproduction for handheld and fixed-mount applications. The microphone is equipped with A-T’s UniGuard™ technology for unsurpassed immunity from radio frequency interference. It also features an 80 Hz UniSteep® filter that reduces pickup of unwanted low-frequency ambient noise. The microphone’s special internal shock mounting eliminates virtually all handling and cable noise. Designed for distortion-free output even in intense sound fields, interchangeable elements (cardioid, hypercardioid and omnidirectional) permit selection of angle-of-acceptance from 100° to 360°.

• Designed for high-quality sound reinforcement, professional recording and broadcasting
  
• Smooth, accurate reproduction for handheld and fixed-mount applications
  
• Superior off-axis rejection for maximum gain before feedback

• Integral 80 Hz high-pass filter switch and 10 dB pad switch
  
• Accepts interchangeable elements to permit angle of acceptance from 100° to 360°
  
• Superior anti-shock engineering ensures low handling noise
