IMPORTANT SAFETY INSTRUCTIONS
1. READ these instructions.
2. KEEP these instructions.
3. HEED all warnings.
4. FOLLOW all instructions.
5. DO NOT use this apparatus near water.
6. CLEAN ONLY with dry cloth.
7. DO NOT block any ventilation openings. Allow sufficient distances for adequate ventila-
tion and install in accordance with the manufacturer's instructions.
8. DO NOT install near any heat sources such as open flames, radiators, heat registers,
stoves, or other apparatus (including amplifiers) that produce heat. Do not place any open
flame sources on the product.
9. DO NOT defeat the safety purpose of the polarized or groundingtype plug. A polarized
plug has two blades with one wider than the other. A grounding type plug has two blades
and a third grounding prong. The wider blade or the third prong are provided for your
safety. If the provided plug does not fit into your outlet, consult an electrician for replace-
ment of the obsolete outlet.
10. PROTECT the power cord from being walked on or pinched, particularly at plugs, conve-
nience receptacles, and the point where they exit from the apparatus.
11. ONLY USE attachments/accessories specified by the manufacturer.
12. USE only with a cart, stand, tripod, bracket, or table specified by the manu-
facturer, or sold with the apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid injury from tip-over.
13. UNPLUG this apparatus during lightning storms or when unused for long
periods of time.
WARNING: Voltages in this equipment are hazardous to life. No user-serviceable parts inside. Refer all servicing to qualified service personnel. The safety certifications do not apply when the operating
voltage is changed from the factory setting.

General Description

The Shure Model UA845UWB Antenna Distribution System allows up to four receivers to use the same set of antennas. There are also power connec-
tors for distributing power to each receiver. RF signal amplification compensates for insertion loss from splitting the antenna input to multiple outputs.
Cascade connectors allow connections to a fifth receiver or a second UA845UWB. A button on the front panel switches between one of five frequency
bands from 174 to 1805 MHz.

System Features

The Shure Model UA845UWB ensures maximum sensitivity and signal processing capability, providing the widest radio range possible for the largest
number of wireless receivers.
• 5 Selectable Frequency Ranges The UA845UWB allows more options for avoiding intermodulation artifacts by switching between one of the five
frequency bands.
• RF Power LED Indicators Front panel LED indicators display red if RF power is overloading.
• Expandability The UA845UWB Antenna Distribution System is designed for large wireless systems. Each unit allows up to four wireless receivers to
use the same two antennas, and the cascade ports allow connection to a fifth receiver or a second UA845UWB.
• Compatibility The UA845UWB is compatible with all Shure wireless microphone receivers operating within a compatible frequency range.
• Cascade Ports Two 50 ohm, BNC-antenna cascade ports allow an additional UA845UWB unit or a fifth wireless receiver. A large wireless system
can be run off of a single pair of antennas.
• Power Output and Out Connectors Multiple receivers can be daisy-chained and powered from a single source via the power output connectors.
• Low Noise and Intermodulation Distortion The UA845UWB maintains clean signals with minimal distortion.
• Insertion Loss Compensation Whenever a signal is split to multiple output ports, there is a loss in signal strength. The UA845UWB amplifies signals
to compensate, ensuring a strong signal to the receivers.
• Front-Mounted Antennas The UA845UWB comes with hardware to front-mount the antennas, if desired.
14. REFER all servicing to qualified service personnel. Servicing is required when the ap-
paratus has been damaged in any way, such as power supply cord or plug is damaged,
liquid has been spilled or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has been dropped.
15. DO NOT expose the apparatus to dripping and splashing. DO NOT put objects filled with
liquids, such as vases, on the apparatus.
16. The MAINS plug or an appliance coupler shall remain readily operable.
17. The airborne noise of the Apparatus does not exceed 70dB (A).
18. Apparatus with CLASS I construction shall be connected to a MAINS socket outlet with a
protective earthing connection.
19. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or
moisture.
20. Do not attempt to modify this product. Doing so could result in personal injury and/or
product failure.
21. Operate this product within its specified operating temperature range.
This symbol indicates that dangerous voltage constituting a risk of
electric shock is present within this unit.
