Required Accessories

The Audio Technica U841A is a wide-range condenser microphone with an omnidirectional polar pattern. It is designed for surface mount applications such as high-quality sound reinforcement, conferencing, professional recording, television and other demanding sound pickup applications.The microphone requires 11V to 52V phantom power or a 1.5V AA battery for operation. A battery need not be in place for phantom power operation. The microphone is equipped with UniGuard RFI-shielding technology, which offers outstanding rejection of radio frequency interference (RFI). The microphone includes a 7.6 m (25') permanently attached miniature cable. Its free end connects to the provided AT8531 power module via a special TA3F type connector to optimize RFI immunity. The output of the power module is a 3-pin XLRM type connector. A 3-position switch in the power module permits choice of off, on/flat response or on, low-roll-off (via integral 80 Hz high-pass UniSteep filter). The roll-off position reduces the pickup of low-frequency ambient noise. The microphone comes equipped with a power module, a battery and a soft protective pouch. The microphone's heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone. The microphone features a low-reflectance black finish.

Features:
Small-diameter UniPoint omnidirectional capsule near boundary eliminates phase distortion and delivers clear, high-output performance
Offers the convenience of battery or phantom power operation
Superior off-axis rejection for maximum gain before feedback
UniGuard RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
Self-contained electronics eliminate need for external power module
UniSteep filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
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

Did You Know...... that while boundary mics are widely utilized in conference rooms and training applications many Audio Engineers use them as drum recording mics. It's true! Musicians and Audio Engineers can benefit from a pair of boundary mics by placing them on the floor on both sides of a kick drum, on the walls or even inside the kick drum. Have fun experimenting to find your killer drum sound.
