The DM 4410 P is a portable conference delegate unit perfectly suited for permanent meeting rooms or temporary discussion-style meetings. The unit features a built-in high-quality loudspeaker and a fixed 14.2 in. (36 cm) gooseneck microphone with illuminated red ring to indicate microphone ON status. Each unit enables participants to speak, register a request-to-speak and listen to other speakers. The unit can either be controlled by the delegate by the microphone button or remotely by the operator/conference chair. The micro phone button has two LEDs to indicate whether the unit is on (RED) or in the request-to-speak queue (GREEN). The loudspeaker is automatically switched off when the microphone is activated to prevent acoustic feedback. A 6.6 ft. (2.0 m) cable is permanently connected to each unit to allow for quick and easy installation of units
