Notes: NOT on PMI Audio's current official Studio Projects store page (which lists mics only, no preamps). Sweetwater's own listing states the page is 'left up for reference only' and the unit is no longer available new — STATUS = manufacturer-discontinued/legacy, found only via eBay/Reverb secondary market at time of research. Gain spec: 72dB max (mic-in), 42dB max (line-in), per official manual. price_usd of $229 is the ORIGINAL MSRP (period reviews note street price under $200 when in production) — flagged as historical, not a confirmed current price.
