Astatic 611L Overview
The Astatic 611L from CAD is a palmheld omnidirectional dynamic microphone offering easy operation and voice-tailored frequency reproduction for public address and vehicular two-way communication. It features a push-to-talk thumb switch for quick momentary activation and an unterminated four-conductor, two-shield coiled cable, which extends to six feet in length. The dynamic capsule requires no power source, and its omnidirectional polar pattern provides a generous pickup area.
With a frequency response of 100 Hz to 7.5 kHz, its audio output is optimized for vocal transmission. The rugged, molded Cycolac housing maintains durability while remaining lightweight. The 611L is an ideal solution for paging systems, dispatch, mobile radio communication, and more.
