Owner Insights
We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Shure UA845 UHF Antenna Distribution System.
Features and functionality
-
The Shure UA844+SWB features cascading functionality, allowing streamlined setups which is beneficial in mobile environments by reducing antenna clutter and power outlet usage.
Source -
The Shure UA845 supports four pairs of antennas and one cascade output, making it suitable for complex setups with multiple receivers.
Source -
Shure UR4+ uses active splitters, which minimize noise but can still add minor noise over multiple cascades, compared to passive splitters.
Source
User experience
-
Owners using the UA844+SWB with multiple receivers report no significant increase in dropouts compared to using individual antennas with each receiver.
Source -
Owners managing 25+ channels with BLX systems highlight that passive antenna splitting can lead to significant signal issues, suggesting active distribution for reliability.
Source -
Owners recommend testing BNC connections with an analyzer to prevent signal issues caused by faulty jumpers, especially in large setups.
Source
Setup and maintenance
-
It's crucial to position antennas above head height to avoid signal interference from human bodies, which can obstruct radio signals due to their water content.
Source -
Grouping receivers by frequency band and using wideband antennas can enhance performance in systems with varying frequency bands.
Source -
Avoid cascading more than 4 receivers to prevent significant signal loss; each passive splitter can introduce a 3dB loss, accumulating to 12dB after 4 units.
Source -
Optimal configuration for 10 receivers involves using one UA845 and cascading outputs directly to minimize noise and ensure each unit is on two active splits.
Source
Software and compatibility
-
The Shure Frequency Finder and Workbench app can aid in coordinating clear frequencies, though manual input is required since the model lacks networking capabilities for direct app integration.
Source -
The UR4D+ units are compatible with Wireless Workbench 6, but not with version 7, which is crucial for coordinating frequencies effectively.
Source
Comparisons
-
Users note that the QLX system performs better than SLX in terms of fewer dropouts, suggesting a worthwhile investment for improved reliability in critical applications.
Source -
The RF Venue distribution system, priced at $500, is suggested as a cost-effective alternative to the Shure UA845, needing fewer units for high channel setups.
