  • Overview


    Engineered for versatile positioning and extremely flexible performance in boardroom, school, government, house-of-worship and other installed applications, the U857AL features a small-diameter gooseneck with virtually no “memory.” Its ultra-flexible, robust design permits easy adjustment into desired shape while resisting inadvertent repositioning. This cardioid condenser gooseneck microphone direct mounts to any 5/8"-27 stand; it is 16.58" long. Equipped with UniGuard® innovations that offer unsurpassed immunity from radio frequency interference, the U857AL accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine™ line cardioid polar patterns. The battery- or phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.

    Answer: 
    The U857AL can be used with the AT8601 Microphone Desk Stand as long as you use the AT8664 cable pass-through adapter that is provided with the microphone between the stand and the microphone. The adapter allows the mic cable, which exists form the bottom of the gooseneck, to exit from the side of the adapter just above the stand.
