CM 4450 P
CDS 4000 Chairman w/Fixed Mic
19.7 in. (50 cm)
Configuration
CM 4410 P
The CM 4450 P is a portable conference chairman unit perfectly
suited for permanent meeting rooms or temporary discussion-style
meetings. The unit features a built-in high-quality loudspeaker and
a fixed 19.7 in. (50 cm) gooseneck microphone with illuminated
red ring to indicate microphone ON status. Each unit enables the
conference chair to speak, register a request-to-speak, listen to other
speakers and override delegates with the priority button. The unit can
either be controlled by the microphone button or remotely by the
operator/conference chair. The microphone 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.
