Audio-Technica U841R Omnidirectional Condenser Boundary Microphone

Audio-technica's U841R omnidirectional condenser boundary microphone brings forth remarkably clear and intelligible audio reproduction from a super-compact, low-profile, surface-mount design. It also features UniGuard® RFI-shielding technology, is phantom-powered, and equipped with self-contained electronics, thus minimizing radio frequency interference (RFI) and eliminating the need for an external power module.

Applications

Great for surface-mount applications, such as:

High-quality sound reinforcement • Professional recording • Television • Conferencing • Other demanding sound pickup situations

Includes

• U841R Mic
• Soft protective pouch

Features

• Designed for surface-mount applications where highly intelligible sound quality is required
• Small-diameter omnidirectional capsule near boundary eliminates phase distortion and delivers clear, high-output performance
• Superior off-axis rejection for maximum gain before feedback
• UniGuard® RFI-shielding technology offers outstanding rejection of RFI
• Self-contained electronics eliminate need for external power module
• Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone
• Low-profile design with low-reflectance finish for minimum visibility
