I've been running the PTU-2U (two of them for 4 ch total) for over a year with no problems, either this unit is faulty or the frequencies aren't available. RF coordination is not 'easy' - it's the wild west, so even if Shure Frequency Finder (should be the first step you take before even buying wireless equipment) says there are 'open' channels, that means every non-licensed device has access to them..
They actually have been very willing to try to work through the issues.. Just this past Sunday I tested the PTU-2U that comes with a dual channel receiver. The actual receiver model is PWR-2U. Channel A covers 530.025MHz - 555MHz, Channel B covers 555.025MHz - 580MHz. The lower frequency of Channel A is what I needed to be able to do a test with the Phenyx Pro in a clear frequency at my location. I asked Phenyx if they mind sending me one, and they express shipped me one. This past Sunday I tested the PWR-2U receiver and it did auto scan, and picked available clear frequencies correctly.. So what you witness in this video is how the auto scan function work when you are at a location that has no clean frequencies. The PWR-1U receiver (which is what is being tested in the video) have a frequency range of 555.025MHz - 555MHz. All those frequencies are unavailable at my location. Which cause the auto scan failure.
@@hiphop360 wow that is very interesting. That’s interesting how your location doesn’t have any open frequencies in that range wow. Have the results been better than what you had in your first video? That was so terrible but sounds like it could have been because all of the frequencies were saturated on that 1U unit. It would be great to see another update with the 2U unit!
@MrMaui38 Beleive it or not it is not uncommon in certain large metro areas that you find that complete UHF band segments are completely filled up.. It is very important to know what is available to you so that you get the right equipment for the location. You can check what's available to you by visiting Frequency Finder at wff.sennheiser.com/ and/or www.shure.com/en-US/support/tools/frequency-finder. Using either of those tools, neither one of them report usable frequencies AT THE TEST LOCATION in the range of 555.025MHz - 580MHZ. However, they do show one small range around 546MHz that I should be able to use at my location... That info actually checks out, my 3 Sennheiser units auto scan only reports that I can use frequencies from 545-548MHZ... Regarding how the 2 channel unit performed when I was able to set it on a clear channel. It worked way better than how the PTU 1u performed, but there was still dropouts and static.. For my use, I still have to consider it as unusable.. I recorded a new test of the 2 channel PTU 2U / PWR-2U. I just need to edit it, and post. When I upload it I will msg you here with the link.
@@hiphop360 this is great information - I appreciate you sharing the links! I will definitely look into this next time I am setting up microphones at an event (I’m a mobile DJ). So far I’ve used the GTD audio 733 which haven’t failed me once but I have no idea which frequencies they operate on and will have to look into this. I’m looking forward to the video, but it’s also good to know that you didn’t have a great result on your latest testing…I’ll hold off on buying these 1U/2U for now and stick with what I have!
Mine has the same problem..seems like the auto scan mever works. I think Phentyx need to show a video tutorial on how to work the auto scan in case we doing a wrong step. But my Microphone cuts off a very short distances.
You may not have any available frequency that the unit can use.. Turns out that is what the problem was...

I spoke to Phenxy Pro about this behavior. They confirmed that the behavior exhibited in the video is how the unit responds when there are no available clear frequencies available in the frequency range that is supported by the device. The PTU-1U receiver (PWR-1U) supports frequency range 555.025MHz to 580MHz. Indeed the location that I performed the test at, the spectrum from 555.025MHz to 580MHz is completely used up by TV stations in the area. Which is why every channel I selected for the receiver would show that it was receiving a high amount of RF despite the mic transmitter being off. The receiver was showing that it was receiving the interfering TV Stations' RF, not the mics.
@@hiphop360 maybe try a mic that uses the 900MHZ range? I use a IEM that uses 900 and it works pretty good, but y'know, these bands are all getting crowded. A 100 foot XLR cable may just be the answer. I noticed that one of my favorite country singers still uses a Beta 58 with an XLR and so does Springsteen.
Thank you for the review. I was going to pick one up, but I will have to go another way.
Both my 1U and 2U work perfectly

Wow you are uncovering a lot of interesting pitfalls about this mic system! I’m interested to hear what Phenyxs response is to this

Maybe try a wireless in the 900Mhz range?

that short distance cut offs you mentioned worry me because I just bought 2 of these damn things
Both of mine work perfectly
Mine is fine!!! No problem at all.
