The MINKEZ's WCCU-131 is a conference system with a 5GHz communication frequency spectrum, which has better anti-interference capabilities and more bandwidth and transmission speed. WCCU-131 adopts 128-bit AES encryption and supports WPA/WPA2 wireless security to prevent eavesdropping and illegal access, giving the conference system a better level of security. A 96-bit, 50-MIPS digital audio DSP processor is included in the core. The sample speeds of 8KHz to 96KHz are also supported by the stereo audio ADC and DAC, as well as digital volume control. Besides that, the output volume can be adjusted, and equalization and noise cancellation methods are supported. Even better, it contains a one-way USB interface that allows for USB recording or playing of backstage music, and two power amplifier output interfaces are available, each of which can be connected to a 225W constant resistance speaker.
