Get to know them!

Merging Technologies Hapi MkIII packs the company’s renowned AD/DA technology into an economical rackmount unit tailor-made for stagebox or studio rack duties. This networked audio interface houses a hard-wired complement of digital I/O, a reference-class headphone amplifier, and comprehensive Ravenna/AES67 AoIP connectivity. That said, Hapi MkIII’s real power rests in its two ultra-flexible option slots, which enable you to configure your system according to your individual needs. Moreover, you get support for up to 32-bit/384kHz PCM digital audio, as well as 358.2kHz/DXD and DSD formats, depending on your installed extension cards. Hapi MkIII is also eminently broadcast-ready, thanks to no-compromise ST2022-7 and NMOS compliance, enabling it to satisfy the demands of modern IP-based facilities. Complete with a vivid front-panel display, Merging Hapi MkIII is a cutting-edge modular audio solution for studio, broadcast, and live sound reinforcement.

Modular design offers flexible expansion

Hapi MkIII makes a superb audio interface for professionals who demand the utmost in sound quality and flexible configurability. Hapi MkIII includes eight channels of AES/EBU I/O, eight channels of ADAT or two channels of S/PDIF, and word clock I/O right out of the box. You also get a mastering-grade headphone amplifier and exhaustive Ravenna/AES67 AoIP connectivity. However, Hapi MkIII’s most significant highlight is its two option slots, which enable you to mix and match extension cards to create your own custom I/O configuration. Merging offers a wide range of expansion modules, giving you the ability to add any combination of transparent-sounding mic preamps, crystal-clear analog inputs and outputs, seamless Pro Tools HD integration, and time-tested MADI connectivity to your setup. Best of all, no matter how you configure your rig, you’ll be able to capture sounds with extreme accuracy, listen to your mixes with supreme confidence, and rest assured that you’re using some of the finest AD/DA technology in the industry.

Brimming with cutting-edge network technology

Merging Technologies Hapi MkIII offers ST2022-7 and NMOS IS-04/IS-05 compliance, which allows it to transcend the capabilities of the SMPTE 2110 standard. This feature-laden interface includes two network ports, enabling you to run it in a redundant ST2022-7 Seamless Protection Switching mode for stress-free operation. Furthermore, it can register itself into an NMOS server and comply with connection requests from an NMOS network manager. Beyond that, Hapi MkIII delivers comprehensive Ravenna/AES67 AoIP connectivity across a standard IP network using off-the-shelf network hardware. What’s more, you can power the device using either AC or DC — standard power sources, battery packs, and miscellaneous wall warts alike — with zero compromises. Here at Sweetwater, we’re especially fond of Hapi MkIII’s robust remote access and control capabilities, which make configuration, deployment, and troubleshooting a breeze. Furthermore, Hapi MkIII’s powerful networking capabilities make it an excellent choice for broadcast facilities that rely on an IP infrastructure.
