The Astatic 878HL-2 from CAD is a desktop omnidirectional dynamic paging microphone intended for use with commercial paging systems in schools restaurants warehouses medical facilities and more. The dynamic capsule requires no power source and its omnidirectional polar pattern provides a generous pickup area. A programmable switch allows push-to-talk or lift-to-talk functionality and selectable output impedance makes the 878HL-2 flexible for use with most paging systems and amplifiers. The four-conductor two-shield cable is 7′ in length and unterminated to allow balanced or unbalanced connectivity. With a frequency response of 80 Hz to 12 kHz its audio output is optimized for vocal transmission. The rugged molded Cycolac housing and die-cast zinc base maintain durability while remaining lightweight. Its desktop design incorporates four non-skid feet to inhibit slippage and surface marring. Programmable Push-to-Talk Switch Long-life DPDT leaf switches and the choice of either a simple push-to-talk bar with locking capabilities or lift-to-talk operation ensure easy operation. Switchable Output Impedance A flexible output impedance switch makes the 878HL-2 flexible for use with most paging systems and amplifiers. Unterminated Cable The 878HL-2 is supplied with 7′ of four-conductor two-shield cable wired normally open for relay control. Intelligible Sound The 80 Hz to 12 kHz frequency response is smooth and peak free with a slight rise above 2 kHz to impart enhanced intelligibility. Non-Skid Feet Four molded non-skid non-marring feet are located under the zinc die-cast base.
