CAD Audio 878HL-2 Astatic Omnidirectional Dynamic Desktop Push to Talk Paging Microphone

The 878HL is a dual impedance, omnidirectional dynamic microphone offering modern styling and features in a rugged Cycolac housing for all industrial and commercial public address and paging applications. A slight rise above 200 Hz gives the 878HL a natural and highly intelligible sound. The 878HL a long life DPDT leaf switch with three types of switch activation, a momentary push bar, a locking on/off switch and lift-to-talk operation. The 878HL is manufactured to take abuse and retain its performance and appearance over a long life. Four molded, non-skid, non-marring, permanently resilient shock isolation -"feet-" are located under the base. The high or low impedance selector switch is located on the bottom of the microphone. The 878HL is supplied with 2.1m ( 7 ft.) of four conductor, two shielded, cable wired normally open for relay control. If a line-shorting switch function is desired, the 878HL can be easily rewired in the field.
