Audiocore WCM-6440U

Audiocore WCM-6440U Wireless Conference Microphone (4 UHF PLL Mic up to 512 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-6440U 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-6440U can be setup simultaneously up to 128 systems (512 mic) at one place with no interference. It has a greater range and clarity than its sibling the Audiocore WCM-3240U.

If you need more microphones in one system, you can use Audiocore WCM-6480U which have 8 conference mic.
