The PA821B Antenna Combiner from Shure is designed to optimize RF management for Shure PSM Personal Stereo Monitor systems. It can be used when multiple systems are required for monitoring on stage, theater, and rehearsal applications.

The combiner efficiently optimizes up to eight PSM transmitters (sold separately) when racked in a central location, while also reducing rack clutter. It is built with LED indicators for signal overload and signal presence. Additionally, the unit's fan design improves thermal efficiency and ambient noise.

Related Questions and Answers

Q: 1. Can this be used with the glxd receiver??

A: This UHF antenna distributor does not work with the Shure GLXD wireless systems, which operate in the 2.4 GHz digital frequency range. The Shure UA846Z2/LC GLXiD Frequency Manager, Less Antenna Cables, BH #SHUA846Z2LC would be the proper antenna distributor for a GLXD digital wireless system. An appropriate antenna would be the Shure PA805Z2-RSMA Passive Directional Antennam, BH #SHPA805Z2SMA.

Q: 2. Is this compatible with the UA844SWB antenna distribution system?

A: Yes, the PA805SWB antenna is compatible for use with the UA844SWB antenna distribution system.

Q: 3. Does this work with SLXD4 receivers ?

A: Yes, the Shure UA844+SWB UHF Wideband Antenna Distribution System (470 to 960 MHz) will work with Shure SLXD4 receivers.

Q: 4. Can this system be configured to work with six systems without needing to use UA221's? It seems like you would need them to use any more than five systems.

A: Yes it can. It's a kit and comes with everything you need including a distro box.

Q: 5. This is not only for BLX units, but for other models as well such as the QLX-D right?

A: The UA844+SWB/LC will support Support QLX-D, ULX, ULX-D, SLX, and BLX (BLX4R only) receivers.

Q: 6. Can you use this with a mix of wireless bands? For example I have 3x H19 (542-572MHz) and 1x G5 (494-518MHz)

A: Yes, the UA844+SWB covers the full range between 470 to 960 MHz so it can be used with the H19 (542 to 572 MHz) and G5 (494 to 518 MHz) wireless systems and any others that fall within the frequency range that the antenna covers.

Q: 7. Does this product come with BNC antenna cables or just the antennas?

A: Yes. see below: In the Box Shure UA844+SWB UHF Wideband Antenna Distribution System (470 to 960 MHz) PS45 Power Supply 4 x Locking DC Power Cables (for ULX4D, ULXP4) 4 x Non-Locking DC Power Cables (for QLXD4, SLX4, and BLX4R) 10 x 22" BNC Cables 2 x 6' BNC Cables 2 x Bulkhead Adapters Rackmount Hardware Kit Limited 2-Year Warranty 2 x Shure UA874 Active Directional Antenna 2-Year Limited Warranty

Q: 8. so a separate power supply is required and does the power supply terminate in a BNC?

A: A separate power supply is not required. The power is supplied from the coaxial connection.

Q: 9. Description says this can handle up to five wireless receivers, but the picture of the back of the unit looks like there are only enough BNC connections for four receivers. Can someone clarify?

A: Michael F. That is correct bro. You can use up to 5 different wireless units. There are two outputs in the back A & B. Each output has 2 sets of out puts for FOUR(4) units, but if you notice next to each output bank youll find 1 cascade on each side equality to two total on the back. If you use those, now you have the capacity to use 5 units. Notice that if you do use the cascade you wont be able to connect multiple units if that was your intention. If youre only using one unit, you will be able to use 5 units using the cascade, if your intention is to use multiple units then 4 max is what you can use per unit. I hope this helps brotha. I use 2 of them for our church and I use 4 wireless units per unit as I have them linked together through cascade.

Q: 10. We ordered this as a replacement part but it is the 6 model and we need the 12 . I do not see the 12 on your site, is it available?

A: Yes it is parallax free. Where the parallax turret would normally be is the adjustment for reticle color and brightness are selected using a dedicated side turret.
