WP300
A dynamic paging hand microphone. NC450D’s noise-canceling design makes it particularly effective for
use in noisy locations and excellent voice response characteristics make it a good choice in quiet areas as
well. Output impedance is 200 ohms for matching low impedance input circuits. A push-to-talk switch
is located on the molded ABS microphone housing. A soft rubber lip guard assures user of correct
microphone-to-mouth positioning.
