The HM150 is a sturdy dynamic CB type handheld microphone with an omnidirectional pickup characteristic. It features an easy to use Push To Talk switch on its side which makes it perfectly suited for paging messages and announcements in applications such as warehouses and shops. While pressing the 2-pole non-latching Push To Talk switch, the microphone is switched ON and the contact for operation with chime modules is simultaneously activated. The switch contacts for the operation of chime modules are connected on Pins 4 and 5 of the 5-pin XLR, while Pin 1(GND), Pin 2 (Sig +) and Pin 3 (Sig -) are used for the balanced microphone output signal. A metal mounting clip is provided with the microphone.
