More about the 878HL-2
The Astatic Model 878HL is a dual-impedance, omnidirectional 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 a 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, and 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.
