840
Common name: Astatic 840
Production Status: Discontinued / Vintage
The 840 is a miniaturized and light weight dynamic lavalier microphone engineered to prevent chest cavity resonance. The microphone includes a spring clip, a neck cord with holder and a 30 feet cable. The 840 is equipped with a DuPont Mylar® diaphragm providing stability, long life and virtually unaffected by moisture, temperature swings and many acids, alkalis and solvents. It is finished in non-reflective brushed satin chrome, non-reflective TV grey finish or brushed gold plating. The 840 is smaller than the 840S as it doesn’t have a contour switch.
