The Shure PA411 wireless antenna combiner makes setting up your PSM 300 wireless in-ear monitor system easy. The PA411 combines the antennas of up to four PT3 wireless transmitters into a single unit with a single antenna - no more fighting to close the rack lid or searching in the dark for a lost antenna.

Shure PA411 Antenna Combiner Features:
  • Main RF output connector connects to any antenna with a BNC connector for excellent transmission
  • Handy RF LED indicators display signal present and signal overload per input
  • Power splitter cable distributes DC power to your transmitters
  • Easy access front panel power switch
Add convenience to your in-ear rig with the Shure PA411!
What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Reviews

It does what it’s supposed to
I'm using this for two Shure PSM300's and a Galaxy AS950. Works great! Powers all the units and combines the antennas. I'm using a Shure UA8 antenna on the combiner without issue

I do think it's a little pricey for what it is, but it is quality and it works.
No more wrestling with multiple antennas and making your IEM racks messy and inefficient. To not combine is a crime!
If you're running more than 2 systems I highly recommend getting this combiner or the higher end model if you can afford it. It's one thing to have wireless connectivity which already is a sense of freedom and relief for my vocalists but I don't want to sacrifice sound quality with having to battle with interference since we run both wireless mics and wireless in-ear monitors. Paired this with a Shure PA805 and our IEM packs deliver crystal clear sound with minimal interference and total flexibility. Definitely a must have for those looking to set up a wireless IEM system with more than 2 receivers!

Great!!!
The device is wonderful!! but I haven't been able to use it yet because I have 4 psm300 transmitters and I can't disconnect the old BNC antennas are very hard I couldn't disconnect them.
Great unit to clean up your rack
A must-have if you have 3-4 PSM300s. I got to combine the antennas and power all my units from one power source freeing up more power for other units in our rack. Works perfect.
