A&M Studios Hollywood (1975–76) 2520 op-amp 312 preamps American punch Large-format 1970s API Preserved at Palomino Sound, LA

The 3224 was API's large-format answer to the growing demand for more channels and buses — 32 channels, 24 buses, with the same 312/550 module architecture that defined the API sound. A&M Studios in Hollywood installed a 3224 in Studio B in 1975 and Studio A in January 1976. A&M was one of the most commercially productive studios of the era, and the 3224 sat at the centre of it — present for a generation of American pop, rock, and soul productions on a label whose roster ran from Herb Alpert to Carole King, Cat Stevens, Peter Frampton, and the Police. The original 1975 Studio B desk — Herb Alpert's desk — was preserved and is still in daily service at Palomino Sound in Los Angeles, where engineer Jason Soda maintains it as a working console rather than a museum piece.
