4.2 Discussion Units

Participants use discussion units to communicate with other members of the event. Connected in daisy-chain
configuration from the central unit, they transport digital audio, control signals, and power over a single cable. The sleek,
professional design and minimal cabling allows seamless integration into professional meeting spaces. A DDS 5900
system supports up to 250 discussion units at the same time.
