Audiocore WCM-3240U Wireless Conference Microphone (4 UHF PLL Mic up to 256 Mic)

In the world of conference microphone system, you need to consider several things, do you want to use a cable conference system or a wireless conference system? And if you choose a wireless conference system, do you want to use VHF or UHF? This decision all depends on your need and situation. It's not as clear cut as looking at the price or decide. They all have their advantages and disadvantages. You can entrust us who are well experienced in the field of conference system setups for many-many years.

Audiocore WCM-3240U is a 4-mic UHF PLL wireless conference system that is suitable for complicated environment while maintaining good sound quality. With the new technology, Audiocore WCM-3240U can be setup simultaneously up to 64 systems (256 mic) at one place with no interference.

If you need more microphone in one system, you can use Audiocore WCM-3280U which have 8 conference mic.
