Description

The Astatic Model 878HL is a duel impedance, omindirectional dynamic
desk microphone offering modern styling and features in a rugged Cycolac
housing for all industrial and commercial public address and paging
applications. The Model 878HL has a slide switch for low or high impedance
selection. The wide band frequency response is smooth and peak free, with
a slight rise above 2K Hz to give that "natural" highly intelligible sound.
The microphone and relay switching is accomplished with long life DPDT
professional leaf switches and choice of either a simple push-to-talk bar
with locking capabilities, or lift-to-talk operation, to give years of dependable,
trouble free performance. The lift-to-talk operation can be disabled with a
slide switch located under the microphone base.

The 878HL is manufactured to take normal abuse and retain its performance
over a long life. Four molded "feet", non-skid, non-marring, permanently
resilient, are located under the zinc die cast base.

Supplied with 2.1m (7 ft.) of four conductor, two shielded cable, the Model
878HL microphone circuit is wired normally open.
