Complies with new FCC frequency rules.

Acesonic has taken this popular model and create the UHF-4000R! The unit now features rechargeable microphones and includes two charger stands. Enjoy using 4 microphones and avoid running out of batteries by simply charging after you use it. This is one of the most convenient setups available so far.

Experience the ultimate freedom and versatility with the Acesonic UHF-4000 Professional 4-Channel Module Wireless Microphone System. The  4-channel UHF wireless microphone system with each microphone on its own independent UHF channel will gives you maximum utilization without the fear of frequency interference. Going wireless means that you are free from cables for up to 100 feet of range from the receiver unit.  Plus, a 12-hour microphone battery life means the singing can last all night. Users will love that each microphone channel has its own field-replaceable module that can easily slides out and service.

Exclusive Features:

Rechargeable: A charger microphone stand is included so you can have the luxury of just placing your mics safely in the stand while eliminating the need to change batteries often.

Rack-mountable and Front-Antenna Design: This wireless receiver can be mounted inside any 19" rack case and the front-antenna design is much more convenient to adjust its angle and it's more extendable than the traditional rear-antenna design system which the antenna is harder to reach and gets weaker reception inside a rack case.

Four Independent Modular Design: Each one of the four receiver module is a Field Replaceable Unit that can be quickly and easily removed and replaced by the user without having to send the entire system to a repair facility.  There are a total of 8 different channel frequency module that you use for replacement.

2 Different Frequency Sets :  You can purchase 2 units of UHF-4000 for a total of 8 microphones use simultaneously without frequency interference. Please call us and ask for a specific frequency set to meet your needs.
