Additionally, premium versions offer even higher specifications and support ultra-high resolution formats DXD, 384 kHz PCM and DSD 256 bitstream. D/A cards feature selectable roll-off filters. D/A trims level (in 0.1 dB increments) and signal polarity can be adjusted for each channel individually to ensure mastering grade precision.

With highly skilled technicians overseeing the manufacturing process, Hapi Mk III is the embodiment of Swiss craftsmanship, where every component is meticulously sourced and tested. The result is an audio device of unparalleled precision and build quality to guarantee longevity and lasting value.

Numerous AoIP Options and Full Redundancy
Hapi Mk III allows users to streamline their AoIP experience, making it more accessible than ever before. With an easy-to-use OLED display for stand-alone operation as well as intuitive web browser control, this network audio mainframe offers unprecedented AoIP flexibility with full support of RAVENNA/AES67 as well as a Dante option. Its redundant network RJ45 connectors ensure reliability and security. The second network port can also be utilized in switch mode to connect an extra interface or system.

Merging has contributed numerous innovations to the RAVENNA/AES67 workflow, and, as a result, Hapi Mk III supports all relevant protocols and standards such as ST2022-7, ST2110, NMOS and even LAWO HOME. Additionally, the inclusion of the ZMAN ARM-based audio network module provides significant performance upgrades compared to the original Hapi, which was already highly popular.

With Merging’s impressive array of software solutions, drivers, and virtual sound cards like MAD, VAD, and ANEMAN, Hapi Mk III is ready to work perfectly with any digital audio workstation (DAW), irrespective of the computer’s operating system.

Dante®
As a new feature of the Mk III model, Hapi now offers optional support for the Dante standard by Audinate, which is highly popular in the live and installation sector. This option adds compatibility with more than 4000 devices from over 600 manufacturers. Hapi Mk III comes Dante Ready™, so users who require Dante can purchase a license from Audinate. Two license models are available, 16x16 I/O and 64x64 I/O. This ensures there are no additional costs for users who do not need Dante.

With the ability to handle an impressive number of 64 streams, 144 input and 146 output channels, the internal router is truly a powerful tool. Therefore, Hapi Mk III is an excellent solution for increasing the channel count of RAVENNA/AES67 interfaces, such as Merging Anubis or Neumann MT 48. Of course, Hapi MK III can also be combined with Neumann’s line of AES67 studio monitors to create stereo and immersive 3D audio setups. With the new Dante option, Hapi Mk III can also be used as the centerpiece or an I/O extension in Dante AoIP environments.

For headphone monitoring, Hapi Mk III features an ultra-low impedance, mastering grade headphone output, conveniently positioned on the front of the unit in both 1/4” and 1/8” TRS format.

The sync port on the back of the unit allows synchronization via LTC, MIDI and Video Reference.
