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 200Hz gives the 878HL a natural and

highly intelligible sound. The 878HL offers 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 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.
