Merging Technologies HAPI MKII  RAVENNA/AES67

MERGING+HAPI has been a hugely popular networked audio converter and instrumental in introducing so many to the exciting world of RAVENNA/AES67. Its economical form factor made it the ideal local stagebox or studio rack unit for any application. Now is the time to build on that success with new technology and new features that still allow full interface card compatibility with the original Hapi and Horus products.

Hapi MKII utilizes the ZMAN technology introduced with Anubis and this powerful processor allows some very meaningful performance upgrades. The recent introduction of the ADA8S and ADA8P cards improved the headroom of the mic-pre inputs and effectively doubled the analog I/O count to 16 in/16 out in DSD, all in 1U rack mountable box.

Merging’s range of audio device options make Hapi the optimum interface for any DAW, regardless of OS.
