CARDIOID CONDENSER BOUNDARY MICROPHONE
U891Rb/U891RWb
Introduction
Thank you for purchasing this product. Before using the product, read through the
user manual to ensure that you will use the product correctly.
Please keep this manual for future reference.
Features
•Cardioid condenser boundary microphone with switch
•Designed for surface-mount applications such as high-quality sound
reinforcement, professional recording, television, conferencing and other
demanding sound pickup situations
•The capacitive touch switch can be set to any of three operating modes:
“touch-on/touch-off”, “touch-to-talk” and “touch-to-mute”
•Integral, phantom-powered, two-state RGB LED indicator displays on/off status
of microphone
•PivotPoint™ rotating output connector allows cable to exit from either the rear
or the bottom of the microphone
•Superior off-axis rejection for maximum gain before feedback
•UniGuard™ RFI-shielding technology offers outstanding rejection of radio
frequency interference (RFI)
•Small-diameter UniPoint™ capsule near boundary eliminates phase distortion
and delivers clear, high-output performance
•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
•Threaded inserts on bottom of microphone allow it to be mounted with screws
for increased security
•Available in two colors: black (U891Rb) and white (U891RWb)
Connection procedure
Connect the output terminals of the microphone to a device that has a
microphone input (balanced input) compatible with a phantom power supply.
The output connector is an XLRM-type with polarity as shown in the figure below.
