Details

I/O: 3-pin XLR balanced analog output

Notable use: All-purpose spot-miking: acoustic/amplified instruments, drum overheads, ensemble/choir, concert recording, sound effects, vocals; Josephson's low-cost, general-purpose entry mic

Notes: SDC (small-diaphragm condenser), fixed cardioid only. Functions down to 24V phantom with reduced max SPL (per datasheet). Price is single-mic USD street price (Sweetwater); matched pair kit C42MP (black chrome finish + hard case) lists ~$1,295 — not separately itemized here. Current draw 4.5 mA. Year of introduction not stated on manufacturer materials found; flagged blank rather than guessed.
