The 878HL-2 Omni Dynamic Desktop Microphone from Astatic is designed for fixed or temporary paging applications. The frequency response is broad with a gentle rise in the high midrange for speech intelligibility. 7’ cable provided with stripped and tinned ends.
The Astatic Model 878HL is a dual 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.
