Proslogan IU Series Dual Wireless Microphone System (IU-2073)

These Mics run on a banned frequencies and this is not being disclosed by the venderChanges beginning in 2017 concerning operation on 600 MHz frequencies. Beginning in 2017, the amount of TV band spectrum available for wireless microphone use is decreasing as a result of the incentive auction, which was completed on April 13, 2017. A significant portion of the TV band spectrum in the 600 MHz band, including most (but not all) of the spectrum on TV channels 38-51 (614-698 MHz), has been repurposed for the new 600 MHz service band for use by wireless services, and will not continue to be available for wireless microphone use. Specifically, wireless microphones that operate in the new 600 MHz service band (the 617-652 MHz and 663-698 MHz frequencies) will be required to cease operation no later than July 13, 2020, and may be required to cease operation sooner if they could cause interference to new wireless licensees that commence operations on their licensed spectrum in the 600 MHz service band. FCC 14-50, FCC 15-140, DA 17-314 Spectrum will continue to be available for wireless microphone use on the other TV channels 2-36 (TV band frequencies that fall below 608 MHz), on portions of the 600 MHz guard band (the 614-616 MHz frequencies) and the 600 MHz duplex gap (the 653-663 MHz frequencies), and in various other spectrum bands outside of the TV bands. FCC 15-100, FCC 15-99

The proslogan IU-2073 order came faster than I thought.. great packaging , sound was great with greater range than expected. Still exploring and will update when l’m ✅ done ..I gave it 4 because of the size of the transmitter ... apart from that everything was cool just as expected . Will always recommend it so far.

The microphones and reciever unit worked flawlessly. I used them at a company picnic function with my PA system. The projection was crisp and clear.

I was and still am pleasantly surprised at how well these mics do in our church. They pick up well and so far we have had no interference. I am well pleased with them and the price was great.

I had a very good experience with the old model bought in 2016 and purchased this one hoping that it will be at least the same if not better but unfortunately it has a very serious problem, the sound is not good at all and big noise coming when you talk or sing. no way to improve it. we tried with different sound system but no result. Hope in future you will note it and improve.All the best. .

Good quality for the price that I've paid for. Work like a champ.

Plugged into a Karaoke and the sound is great!

2 xlm outputs and it works great.
