The U-2100 Omnidirectional UHF Wireless System from Nadyincludes a 100-channel U-2100 dual receiver, an AC-2100 power supply, two HT-1100 handheld transmitter microphones, and two HM-35 omnidirectional headmic condenser microphones. The U-2100 has 100 selectable UHF frequencies to provide clear and transparent audio with full frequency response. The rugged ABS housing doesn't give way for a long time. The system offers uninterrupted PLL UHF performance with 120 dB dynamic range and line-of-sight operation up to 500'.

The HM-35 omnidirectional headmic condenser microphone is optimally designed for singing and speech applications. The HM-35's small size and light weight make it ideal for all hands-free use with minimum visibility. It is suitable for singers/musicians (drummers, keyboard players), vocal/dance performers, DJs, television announcers, public speakers, and aerobics instructors.

Instead of using the supplied lavalier microphone, can I attach an ordinary dynamic microphone to the transmitter with an XLR to 3.5mm cable? Will it work?
Asked by: clyde
No it will not work. This transmitter requires using the 3.5mm locking connector along with the pin configuration that Nady uses. A lot of companies will use the same physical connector being the locking 1/8 connector, but the positive/negative/ground configuration may vary between manufacturers.
