Audio Technica AT871UG (Unidirectional Condenser Boundary Microphone)
Product Details
Brand: Audio Technica
-
- Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations.
- UniGuardTM RFI-shielding technology offers outstanding rejection of radio frequency interference(RFI).
- Superior off-axis rejection for maximum gain before feedback.
- Small-diameter UniPoint capsule near boundary eliminates phase distortion and delivers clear, high-output performance.
- Heavy die-cast case and non-silp silicon foam bottom pads minimize coupling of surface vibration to the microphone.
- Low-profile design with low-reflectance finish for minimum visibility.
- AT871UG has contained electronics eliminate need for external power module.
- The AT871UG requires 9V to 52V phantom power for operation only.
