The API Audio ASM164 is a 19″ rack-mounted 16-channel analogue summing unit that transposes the legendary summing section of THE BOX® console into a compact and accessible format. Designed for professional studios, home studios and hybrid setups, it delivers classic API sound with depth, clarity and separation.

Each channel features an API 2510 input op-amp, 31-position level control, continuous pan and send/return insert for easy integration of external processors. Two stereo busses (Mix-A and Mix-B) allow flexible routing, while DB-25 and XLR connectors ensure easy integration with DAWs and patch bays.
