Shure UA844plus SWB Antenna Specification

The Shure UA844plus SWB Antenna Distribution System is designed to enhance the performance and efficiency of wireless microphone systems. It allows users to connect a single pair of antennas to multiple wireless receivers, thereby minimizing the need for multiple antennas and reducing clutter. This system is compatible with Shure's QLX-D, ULX, SLX, and BLX (BLX4R only) wireless systems, offering broad flexibility in various audio environments.

The UA844plus SWB functions as an active antenna splitter, ensuring consistent RF signal distribution without degradation. It provides RF amplification to compensate for insertion loss, maintaining optimal signal integrity across connected devices. The system is equipped with a wideband frequency range of 470-952 MHz, accommodating a vast array of applications within its operational bandwidth. With the capacity to support up to five wireless receivers per unit, the system can be expanded further by cascading multiple UA844plus units, making it scalable for larger setups.

The UA844plus SWB includes front-mounting antenna hardware and rack-mounting accessories, facilitating easy integration into existing audio setups. Power distribution is streamlined through its ability to supply DC power to connected receivers, reducing the need for multiple power sources and simplifying setup. The robust construction and reliable performance of the Shure UA844plus SWB make it a vital component for professional audio environments, delivering enhanced signal reliability and streamlined antenna management for efficient operation.

Shure UA844plus SWB Antenna F.A.Q.

How can I connect multiple receivers to a single UA844plus SWB antenna?

The UA844plus SWB is designed to distribute RF signals from a pair of antennas to multiple receivers. Connect your antennas to the unit's antenna inputs and then connect the outputs to up to four receivers. Use the cascade port to connect additional UA844plus units if more than four receivers are needed.

What is the best way to position the UA844plus SWB to ensure optimal signal reception?

Position the UA844plus SWB in a location with a clear line of sight to the transmitters. Antennas should be elevated and away from metal objects and other RF equipment to minimize interference. Experiment with different placements to find the best reception quality.

How do I troubleshoot signal dropouts with the UA844plus SWB?

First, check all cable connections to ensure they are secure. Verify the antennas are properly positioned and free from obstructions. Ensure that the UA844plus SWB and receivers are on compatible frequency bands. If problems persist, try repositioning the antennas or using different cables.

Can I use the UA844plus SWB with different brands of wireless microphone systems?

Yes, the UA844plus SWB can be used with different brands as long as they operate within the compatible frequency range and have the appropriate connections. Ensure that the systems are within the unit's frequency capabilities.

What maintenance steps should be taken to ensure the UA844plus SWB operates effectively?

Regularly inspect the unit for dust accumulation and clean with a dry, soft cloth. Check all connections for wear and ensure they are secure. Periodically test the system to ensure it is functioning correctly and replace any damaged cables immediately.

Is it possible to mount the UA844plus SWB in a rack, and if so, how?

Yes, the UA844plus SWB can be rack-mounted. It comes with rack ears and screws for installation. Attach the rack ears to the sides of the unit and secure it into a standard 19-inch audio equipment rack.

How do I know if the UA844plus SWB is compatible with my wireless system?

Check the frequency range of your wireless system and compare it with the UA844plus SWB's specified range. The unit supports a wideband range, but compatibility must be confirmed to ensure proper function.

What should I do if the power LED on the UA844plus SWB does not light up?

Ensure that the power cable is properly connected to both the unit and a working power outlet. Verify that the power switch is in the 'on' position. If the LED still does not light up, try using a different power outlet or cable.

Can the UA844plus SWB be used outdoors?

The UA844plus SWB is designed for indoor use. If used outdoors, it must be protected from moisture, extreme temperatures, and direct sunlight. Consider using a weatherproof enclosure if outdoor use is necessary.

How can I extend the range of my wireless system using the UA844plus SWB?

To extend the range, position the antennas connected to the UA844plus SWB as high and unobstructed as possible. For larger areas, use additional UA844plus units connected via cascade ports to maintain signal strength across greater distances.
