U841A Omnidirectional Condenser Boundary Microphone

The U841A delivers exceptionally intelligible audio reproduction in a super-compact, low-profile design. Equipped with UniGuard® RFI-shielding technology, this omnidirectional condenser boundary microphone is designed for clear, highly intelligible sound reinforcement, professional recording, television and conferencing in surface-mount applications. The U841A has a 360° pickup angle and operates on battery or phantom power.

Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations

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

Small-diameter UniPoint® capsule near boundary eliminates phase distortion and delivers clear, high-output performance

Heavy die-cast case and silicone foam bottom pad minimize coupling of surface vibration to the microphone

Low-profile design with low-reflectance black finish for minimum visibility

Operates on battery or phantom power

low signik on U841a

Hi
I have just received my new u841a boundary mic. When I connect it to my t.c. electronics desktop konnekt 6 firewire sound interface, i have to turn the gain in max on the interface to have a ok soon level. Is the u841a with a special low output signal? I have a new battery in the phantom power box. Can anyone help me?
