  • Overview


    With advanced capsule design coupled with carefully engineered internal electronics, the U857QLU UniLine® condenser delivers clear, consistent sound for a variety of installed applications. The 23.74" version of U857QU, the U857QLU features Audio-Technica’s UniLine® line-cardioid element. The microphone is designed to plug directly into a panel- or desk-mounted XLRF-type connector. Its ultra-flexible, robust gooseneck permits easy adjustment into desired shape while resisting inadvertent repositioning. Featuring UniGuard® innovations that offer unsurpassed immunity from radio frequency interference, the U857QLU accepts new interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns. The phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.

  • Q & A

    what is the model number of the base that goes with this unit. looking for something with a button and phantom power.

    stereo shop

    The AT8615Rs or the AT8666RSP will work.

    AudioSolutionsManager

    Does this unit have a built in preamp, I need a microphone without a preamp as my mixer has a built in preamp on all channels that can not be turned off.

    rick

    No there is no internal preamp. In your question, it sounds like you may be asking about phantom power rather than a preamp. Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at audio-solutions@atus.com for assistance with this.

    I cannot get this mic to work in the same cable that my Shure SM58 mic works in. Are they not compatible?

    Paul

    The U857QLU has a standard XLR connection at the base, therefore it is compatible with that same cable. However, the U857QLU is a Condenser microphone and will require Phantom Power to operate (requires a minimum of 11V). The SM58 is a Dynamic microphone and does not require Phantom Power to operate. If you are still having issues, please contact Audio-Solutions at ATUS (330)-686-2600 ext. 5000

    What is the maximum bend that can be achieved in each of the flexible parts. Can you put a 90 degree bend in each flexible part?

    Bill1234

    You can.
