Description
This is a replacement beltpack transmitter for the Chord NU4 wireless UHF system, tuned to the 864.8MHz frequency and marked in red for easy identification. A beltpack (sometimes called a bodypack) clips to your belt or waistband and pairs with a lapel or headset microphone, so the performer or presenter keeps their hands free while moving around. If you have lost or damaged the original unit, this drop-in replacement gets your system back up and running without needing to buy a whole new kit.
The transmitter runs on 3Vdc from two AA batteries, so there is no proprietary cell to source and swapping a set mid-event is quick. It measures 205 x 68 x 25mm and weighs 76g without batteries, which keeps it light enough to wear for long stretches without much notice. Because the NU4 range comes in four different frequencies, you can run more than one channel at once without the signals clashing, which is handy for panel discussions, theatre work or worship settings.
This particular unit is the 864.8MHz version. When you order a replacement, match the frequency to the receiver channel you want it to work with, and use the red colour code to tell your beltpacks apart when several are in use at the same time. It works as part of the wider Chord NU4 UHF system rather than as a standalone microphone, so you will need a compatible receiver and a mic to complete the setup.
