Astatic 878HL Microphone User Manual


 
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.
Available in black.
