Designed for permanent installation, the U853PM cardioid condenser hanging microphone comes equipped with a wall/ceiling plate power module. The phantom-powered microphone features UniGuard innovations that offer unsurpassed immunity from radio frequency interference. It accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine line cardioid polar patterns. Its 80 Hz low-cut UniSteep filter reduces pickup of low-frequency ambient noise.

- Designed for suspension over choirs, instrumental groups and theater stages
- Wall/ceiling plate power module permits permanent installation in standard metal U.S. single gang electrical box
- Superior off-axis rejection for maximum gain before feedback
- UniGuard RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
- UniSteep filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
- Accepts interchangeable elements to permit angle of acceptance from 90 degrees to 360 degrees
- Low-profile design with low-reflectance finish for minimum visibility
- Available in two colors: black (U853PM) and white (U853PMW)
