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.
The U841R is a wide-range condenser microphone with an omnidirectional polar
pattern.
It is designed for surface-mount applications such as high-quality sound reinforce-
ment, conferencing, professional recording, television and other demanding sound
pickup applications.
The microphone requires 11V to 52V phantom power for operation.
The microphone includes a 7.6 m detachable miniature cable with a special
TA3F-type connector that attaches to the microphone and an XLRM-type output
connector.
The microphone comes equipped with a soft protective pouch. The microphone's
heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of
surface vibration to the microphone. The microphone features a low-reflectance
black finish.
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.
For product improvement, the product is sublect to modification without notice.

• Small-diameter omnidirectional capsule near boundary eliminates phase
distortion and delivers clear, high-output performance
• Superior off-axis rejection for maximum gain before feedback
• UniGuard® RFI-shielding technol-ogy offers outstanding rejection of radio
frequency interference (RFI).
• Self-contained electronics eliminate need for external power module
• Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling
of surface vibration to the microphone
• Low-profile design with low-reflectance finish for minimum visibility
