Details

Controls: Mechanical rear-vent adjustment (reached through an opening in the grille) to switch capsule between cardioid and omni operation

I/O: 3-pin XLR balanced analog output

Notable use: Smooth, less-harsh alternative to conventional dual-diaphragm large-diaphragm mics for general studio use; pattern adjustability suits both close spot miking (cardioid) and ambient/ensemble pickup (omni)

Notes: LDC (large-diaphragm condenser), single diaphragm. Made in USA per datasheet. 2 mA current draw. Year of introduction (2010) sourced from secondary retailer content, not a Josephson datasheet — flagged, moderate confidence.
