The Astatic 878HL-2 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-2 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-2 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-2 microphone circuit is wired normally open.
