Description

The Merging Hapi MKII is the logical step up from the phenomenally successful Hapi which enjoyed record sales in 2020. HAPI is both the perfect primary interface for smaller systems as well as the ultimate accessory for a system using Horus where a smaller stage box is required. 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 stage box 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 significant 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 makes Hapi the optimum interface for any DAW, regardless of OS.

Able to carry the same AKD8D/AKD8DP and DA8/DA8P or ADA8S/P analog cards that fit in the Horus option slots and connect to any RAVENNA or AES67 network the HAPI provides a more cost-effective solution than the Horus without having to make a single compromise in quality. The big news is that the introduction of the ADA8S and ADA8P has turned this into a 16 in and 16 out capable device. Hapi MKII also takes advantage of recent technology improvements that are being rolled out across the Merging range of Networked Audio Interfaces.

Horus Quality, Hapi size

Able to hold both the standard and premium analog cards from the Horus means that Hapi owners get the exact same sound that Horus users have been winning awards with for almost a decade now.

RAVENNA and AES67

Using RAVENNA/AES67, Hapi is able to provide flexible connectivity of every single input and output across standard networks, using off-the-shelf network equipment. The future is most definitely networked audio, and Hapi provides it today. https://www.ravenna-network.com

Broadcast Standards Compliance

Merging has kept abreast of AoIP developments by participating in international showcases and standardization events. It is no surprise that Hapi MKII complies with the key broadcast requirements.

Complete Control over LAN

Hapi is designed to fit into hard-to-reach places Hapi comes with an integrated web server showing the same control interface as is available on the on-board display allowing any web-enabled device to access all the parameters of each Hapi unit over the network. Merging’s Audio Network MANager, ANEMAN can easily manage AoIP networks of any size.

Synchronize your Network

Hapi can be synchronized to video input (black burst or trilevel HD), word clock, network (PTP), AES-EBU, ADAT, SPDIF, MADI or internal clock. It can also serve as network grandmaster (PTP).

The Perfect Solution for:

Stagebox or Portable Use
Hapi MKII is perfect for smaller installations where fewer analog I/O is needed. Managing suspended mics in a concert hall, receiving incoming streams from remote broadcast production, Hapi is a compact form factor that is easy to move or screw into a rack. Redundant power is also easy to implement or it can be powered by a battery if no mains power is available.

3rd Party Workstations Welcome
Mac or PC, users now have access to one of the most sonically impressive mic preamps and AD/DA interfaces the audio industry has ever seen. Using dedicated RAVENNA/AES67 drivers, users of any software on either the Mac or PC platform are able to use Hapi as their I/O solution. The PT64 option card provides 64 channels of low latency Pro Tools HD connectivity and allows Pro Tools users to take advantage of RAVENNA and AES67 AoIP capabilities.

Small I/O Stage Box
For recording setups where smaller amounts of inputs or outputs are needed in a variety of locations around the room, Hapi provides a cost-effective solution with mind-blowing results.

The Ultimate Mastering Interface
If immersive music mastering is your specialty and Anubis ran out of I/O, just add a Hapi to the network and seamlessly integrate the two units with full network control. With analog option cards that match a level of quality never heard of before (no pun intended) and one of the only converters ever to be known for “not having a sound at all”, Hapi is able to provide just the right amount of I/O without pushing budgets too far.

Post-Production I/O
The perfect post interface has arrived. Just enough analog and digital I/O and a comprehensive set of referenced sync options including LTC/MTC and video reference, all connected using nothing more than a simple CAT5E/CAT6 cable. Hapi provides a professional I/O solution for the truly networked post studio.

Installation AV with Ovation
Match the power of Merging’s multichannel audio and show sequencer with Hapi units placed strategically around the installation to provide the ultimate flexibility in creative AV.
