This CouncilMAN conference system package (CM-4) is for 4 users and is the easiest, portable conference system there is. It includes three delegate Mics and one Chairman Mic that can mute all of the delegates if needed. It also includes one AN-100CM+ speaker amplifier that powers up to ten conference mics, three 4 ft. XLR cables and one 25 ft. XLR cable and it comes in a sturdy cardboard carrying case. This system is very flexible and simple to use. It can travel from the council chambers to a community center with easy set-up. It's ideal for smaller rooms of 150 people or less. For larger spaces, just add a liberty platinum speaker to reach up to 1500 people. No other system provides such excellent sound and speech quality.
