U857QL Cardioid Condenser Quick-Mount Gooseneck Microphone

The 18.94" version of the U857Q, the U857QL cardioid condenser quick-mount gooseneck microphone is designed to plug directly into a panel- or desk-mounted XLRF-type connector. The microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations. It features an ultra-flexible small-diameter gooseneck and accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns. Equipped with self-contained electronics, the phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.

  • Designed for high-quality sound reinforcement, professional recording and broadcasting

  • Superior off-axis rejection for maximum gain before feedback

  • UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)

  • Easy-to-adjust, rugged, small-diameter, alternating gooseneck with virtually no “memory” permits quick positioning into desired shape

  • UniSteep® filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality

  • Self-contained electronics eliminate need for external power module

  • Accepts interchangeable elements to permit angle of acceptance from 90° to 360°

  • Two-stage foam windscreen yields dramatically improved resistance to P-pops and other breath blasts

  • Quick-mount design with 3-pin XLRM-type connector insert at base plugs into any standard XLRF-type surface or cable connector

  • Included shock mount attenuates noise, shock and vibration transmitted through the mounting surface

DIFFERNCE BETWEEN 857QL AND 859QL

Hello,
I would like to know the differnce between U857QL and U859QL. I noticed a big price difference.
I am looking to buy 2 for our church.
Could you please help me on this. I asked to a guitar center sales man and it was not helpful.
Thanks
