The unit has a display which shows the frequencies being used by the
microphones. The display shows that our mics are using:
517.600 Mhz
561.350 MHz
Those are outside the frequency you describe, Don, and outside the
frequency the manual says the unit operates in. Right?
I can change the frequencies. However, when I tried to set it to a higher
frequency, I was not able to do so.
The manufacturer's corporate offices are in Brea, CA, USA, and Berlin,
Germany. In the manual, they say the unit complies with FCC rules.
Perhaps the units were modified by the manufacturer to comply with FCC
rules, but the table of specs in the manual was not updated.

It does appear to be a compelling value but a note of
caution: this unit
appears to include prohibited frequencies within its operation range. There
were changes in the FCC's allowed frequency range for this product type in
the U.S. 10+ years back. Quoting the FCC:
"What frequency is banned by the FCC for wireless microphones?
"Certain wireless microphones can create interference over spectrum bands
used for critical public safety communications and wireless broadband
services. To preserve the integrity of those communications, the FCC
prohibits the use of wireless microphones and similar devices that operate
between 698 and 806 MHz (known as the “700 MHz Band”). Similar devices,
such as wireless intercoms, in-ear monitors, audio instrument links and
cueing equipment, are also prohibited. Wireless device operators --
including theaters, churches, schools, conference centers, and theme parks
-- were required to retune or replace their equipment no later than June
12, 2010. Wireless microphone operations outside of the 700 MHz Band were
not affected by this prohibition."
The unit's specs say it operates over 590-890 MHz (pg 17 of the pdf at
https://downloads.monoprice.com/files/manuals/600060_Manual_220523.pdf).
I'm no expert here - just aware of the frequency issue from looking at
used gear before buying my own Shure PGX-D system. One might consider
setting the unit frequency to outside the prohibited range, but the FCC
specifically states units that *can* operate in a prohibited frequency are
illegal - even if they aren't set to one of those. It could be that this
system omits the 700 MHz band from within the total spec'd range, but you
may want to check on that before commiting and risking a potential fine.

We haven't had the trouble that you describe,
Joe, or really any
annoyance other than the one I described with the headset slipping.
Batteries are standard AA. We use rechargeable batteries but one-use,
e.g. Duracell are fine, of course. When the batteries run down, it simply
stops transmitting without any noise as it winds down. I recharge the
batteries before each dance. No-brand AAs lasted about 30 hours.
Range is about 80 meters, according to the manual. I've used it out to
75' with no drop in signal.
Each (balanced) XLR output carries a channel. So, if you want stereo
output use these.
Yes, there is a _quarter inch TRS _unbalanced_ output that combines the
two channels into one mono signal. I plug-in a 1/4" TS unbalanced (mono)
cable and it carries both channels.

Set up is just plug in and go with no technical skill required to
operate the essential functions.
Were rather pleased with it.

I'm using a nice little wireless thing I
bought for like $50. Sound
quality is great...except when it isn't. After working fine for a while,
the sound gets dirty and then has dropouts until you power-cycle the
headset. It has USB-charged batteries.
Does your unit have any trouble like that? How far can you really get
from it? I see two XLRs on the back. There's another output, which is an
even mix of the two. What kind of plug is that? Is it a regular 1/4" or
1/8"? Is it stereo, or just a mono mix?
Shoppingly yours,
