Features

  • Activation switch can be set to any of three operating modes: “press-on/press-off,” “press-to-talk” and “press-to-mute”
  • PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone
  • Small-diameter UniPoint cardioid capsule near boundary eliminates phase distortion and delivers clear, high-output performance
  • Superior off-axis rejection for maximum gain before feedback
  • UniGuard RFI-shielding technology offers outstanding rejection ® of radio frequency interference (RFI)
  • Self-contained electronics eliminate need for external power module.
  • UniSteep filter provides a steep low-frequency attenuation to ® improve sound pickup without affecting voice quality
  • Available interchangeable elements permit angle of acceptance from 100° to 360°
  • 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 finish for minimum visibility
  • Available in two colors: black (U891Rx) and white (U891RWx)

Description

  • The U891Rx is a wide-range condenser microphone with a cardioid polar pattern. It is designed for surface-mount applications such as high-quality sound reinforcement, conferencing, professional recording, and other demanding sound pickup applications.
  • The microphone features an activation switch that can be set (via a switch on the bottom of the microphone) to any of three operating modes: “press-on/press-off,” “press-to-talk” and “press-to-mute”.
  • The microphone requires 11V to 52V phantom power for operation.
  • The microphone is equipped with UniGuard RFI-shielding technology, ® which offers outstanding rejection of radio frequency interference (RFI).
  • The microphone’s cardioid polar pattern provides a 120° angle of acceptance (cardioid in hemisphere above mounting surface). Additional interchangeable elements with omnidirectional (360°) and hypercardioid (100°) pickup patterns are available.
  • The microphone includes a 7.6 m (25′) output cable terminating in special TA3F-type and XLRM-type connectors designed to optimize RFI immunity. The output of the microphone is a TB3M-type connector. The microphone is equipped with Audio -Technica’s unique PivotPoint rotating ® output connector.

Installation and Operation

  • The U891Rx requires 11V to 52V phantom power for operation.
  • Output is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot”— positive acoustic pressure produces positive voltage at Pin 2.
  • The microphone should be placed on a at, unobstructed mounting surface, with the front of the microphone facing the sound source.
  • The sound source should not be below, or higher than 60° above, the plane of the mounting surface.

  • An activation switch on the microphone offers three choices of switching bmodes. The SW. FUNCTION switch located on the bottom of the bmicrophone selects the desired mode. TOUCH ON/OFF: Press the on/ off switch once to turn the microphone on; press again to turn off. MOM. ON (momentary on): Microphone is on only while the switch is being pressed (“press to talk”). MOM. OFF (momentary off): Microphone is off only while the switch is being pressed (“press to mute”). The red LED on the top of the unit indicates when the microphone is “on.”
  • An integral 80 Hz high-pass UniSteep filter provides easy switching ® from a flat frequency response to a low-end roll-off. The roll-off position reduces the pickup of low-frequency ambient noise (such as traffic, airhandling systems, etc.), room reverberation and mechanically coupled vibrations. To engage the UniSteep filter, slide the switch toward the ® “bent” line.
  • The microphone’s PivotPoint rotating output connector allows the cable ® to exit from either the rear or the bottom of the microphone without the need for tools or disassembly.
  • Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110° F (43° C) for extended periods. Extremely high humidity should also be avoided.

Note:

  • Audio-Technica has developed a special RFI-shielding mechanism, which is an integral part of the connectors in the UniPoint line. If you remove or replace the connector, you may adversely affect the unit’s RFI immunity. Audio-Technica offers a crimp tool (ATCT) and RFI shields that enable you to shorten the cable and correctly reinstall the connector while maintaining the highest level of RFI immunity.
  • Placing any object on a surface (such as a conference table) before its finish is fully cured may result in damage to the finish.
