The WAM-402 is a wireless, DSP-based conference system that subtly and automatically carries out a number of functions in the background. Thus, it is also suitable for environments without present technical personnel such as video conferencing, large meetings or public sessions. Voice signals are detected intelligently, feedback and background noise thus successfully prevented. The WAM-402 is very flexible thanks to numerous accessories
