Crown CM30S60 Microphone The Crown CM-30 is a professional-quality, supercardioid condenser microphone designed for inconspicuous miking of a choir, orchestra or stage. Nearly invisible and with a built-in (removable) hanger for easy positioning, the CM-30 is the choice for church choir and overhead stage miking. Smooth, wide-range response makes the CM-30 ideal for natural reinforcement or recording, while its ultratight supercardioid pattern provides impressive gain-before-feedback while rejecting unwanted noise and reverb. Electronics for the CM-30 attach straight to a rectangular electrical box. Accepts phantom power and includes 60' cable and electronics. Available in black or white versions.
