  • Overview


    A wide range condenser microphone with a cardioid polar pattern, the U891RCx is equipped with local or remote switching options. For flexible control in conference and boardroom installations, the unit’s external contact closure ability allows a user to trigger an external device—a camera, for instance—from a switch on the microphone. Another ease-of-use feature: the microphone’s activation switch can be set to three operating modes: touch-on/touch-off, press to talk, and press to mute. The mic is also equipped an 80 Hz low-cut UniSteep® filter to reduce pickup of low-frequency ambient noise. Its red LED status indicator can be controlled remotely. UniGuard® innovations offer unsurpassed immunity from radio frequency interference; interchangeable elements are available in cardioid, hypercardioid and omnidirectional polar patterns; a unique rotating PivotPoint® connector changes the cable exit point—no tools required. It requires 11 to 52V DC phantom power, which operates the microphone and switch circuitry.
  • Features


    • Designed for surface-mount applications such as high-quality sound reinforcement, conferencing, distance learning and other demanding sound pickup situations

    • An activation switch can be set to any of three operating modes: “touch-on/touch-off,” “touch-to-talk” and “touch-to-mute”

    • External contact closure capability permits control of remote devices from microphone switch

    • External LED control allows for accurate depiction of the live status of the microphone

    • PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone

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

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

    • Heavy die-cast case and non-slip silicone foam bottom pads minimize coupling of surface vibration to the microphone

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

    • Improved switch design

    • Q:

      Could Audio-technica provide a supported/recommended source (along with item#) and AWG recommendation for the 5 conductor cable to be used with these mics? I've struggled a little finding cable with the exact number of pairs (don't want to deal with extra pairs) and what AWG would be good. We want to use quality cable to integrate this mics.

      Thanks in advance.

        A:

        The standard 3 audio connections may have a standard 3 pin XLR soldered to it.

    • Q:

      Hi. I want to the 5-condutor shielded end of the cable to be a female XLR so I can connect it to a mixer or DAW. How do I do that?

        A:

        Thank you for your inquiry. I assume that you just need the audio portion of the cable, so pin 1 is ground, pin 2 is audio plus and pin 3 is audio minus, which is the same as a 3 pin XLR.
