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

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?

Wireless compatibility?

Could a U841a be interfaced with an ATW-T310b to run wireless.

Answer: 
Thank you foryour inquiry. If you are using a Windows system, make sure that you have turned up the volume of the input in your control panel for the recording device. Also, make sure the input is a mic level input and not a line level input. Please note that Mac laptops only have a line level input.

Answer: 
Thank you for your inquiry. You will need a standard XLRF to XLRM microphone cable. The power module has an XLR male connector. Please note if your mixer provides phantom power, the microphone will use it. If not it will use the on board batery.
