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
• Designed for suspension over choirs, instrumental groups and theater stages
• UniLine™ polar pattern provides narrow 90° acceptance angle
• Superior off-axis rejection for maximum gain before feedback
• UniGuard™ RFI-shielding technol-ogy offers outstanding rejection of radio
frequency interference (RFI).
• UniSteep ® filter provides a steep low-frequency attenuation to improve sound
pickup without affecting voice quality
• Accepts interchangeable elements to permit angle of acceptance from 90° to
360°
• Low-profile design with low-reflectance finish for minimum visibility
• Available in two colors: black (U853RU) and white (U853RWU)
■ Notes on use
The U857RU require 11V to 52V phantom power for operation. A uniform 90°
angle of acceptance provides well-balanced audio pickup over a narrow area.
Avoid leaving the microphone in the open sun or in areas where temperatures
exceed 43°C for extended periods. Extremely high humidity should also be
avoided.
■ Safety precaution
Although this product was designed to be used safely, failing to use it correctly
may result in an accident. To ensure safety, observe all warnings and cautions
while using the product.
