Designed for paging calls and general announcements, the PM-660D desk-top microphone comes with a large talk switch and a lock lever for easy and convenient operation. Its robust anti-vibration construction and balanced output render the microphone resistive to noise. In addition, the PM-660U microphone is equipped with a remote control switch (interlocked with the talk switch) for amplifier power on/off operation or chime activation.
