Crown CM31S60 Description:

The Crown CM-31 is a professional-quality,supercardioid condenser microphone designed for inconspicuous miking of a choir, orchestra or stage. It also can hang over conference tables or discussion groups for inconspicuous isolated miking. The CM-31 consists of two parts: the micro-phone with a permanently attached 60' cable and the cylindrical electronics power module. The mic cable connects to the power module which adapts the microphone for phantom powering and includes a low-cut switch. Cable connection is via miniature 3-pin connectors. The power module output is balanced, low imped-ance. It is protected against static and radio-frequency interference. The CM-31 has a smooth, wide-range frequency response for natural reproduction of the singing voice, organ or other musical instruments. Extreme low frequencies are filtered out to reduce pickup of room rumble. The microphone has a built-in removable hanger which allows easy position adjustment.
