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.


  • UHF international standard frequency range without interference, The WCM-6440U has a broad UHF frequency range of 500MHz-900MHz and has a 64 selectable frequency for each channel, up to 512 microphones in total can be used simultaneously in one system.
  • Multi-adjusting frequency (several set can be used simultaneously up to 512 microphones).
  • The WCM-6440U has a micro-processor control and phase-locked loop frequency synthesis technology.
  • Multi-channel high quality sound surface wave filter with high quality anti-interference system.
  • Equipped with LCD screen to monitor the working parameters, easy to read and user friendly.
  • Equipped with adjusting knob in the receiver modules.
  • Professional audio output: XLR balanced output and 6.3 unbalanced output.
  • Auto-mute and noise cancelling circuit, eliminating the noise when user turn the mic on or off.
  • Using a reliable SMT production for high-end conference system.
  • Built-in rechargeable lithium battery to save cost of having the need to change battery every now and then.
