Omnidirectional Pick-up Push-to-talk with locking switch Stripped and tined cable Hi or Low impedance output External Contact Closure
Details
The 878HL-2 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.
Omnidirect Dynamic Desktop Mic w/Locking Push2Talk Switch.
TheAstatic 878HL-2fromCADis 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.
