The Merging Technologies HAPI MkIII is a cutting-edge, Swiss-engineered audio interface designed for professional studios, live events, and broadcast applications, offering modular I/O configurations, superior audio quality up to DXD and DSD resolutions, seamless integration with RAVENNA/AES67 and Dante networks, remote browser control, dual redundant network ports, and extensive routing capabilities—all packed into a compact 1U rack unit. Exceptional Audio Quality and Modular Design At the heart of the HAPI Mk III lies an innovative modular design with two slots for Merging’s proprietary I/O and preamp extension cards, allowing professionals to customise the unit to suit specific workflows. The A/D cards utilise a unique dual-gain topology, providing up to 78 dB of gain and delivering a dynamic range of up to 136 dB (mic) and 139 dB (line). These premium cards support high-resolution audio formats, including DXD 384 kHz PCM and DSD 256 bitstream. The D/A cards feature adjustable roll-off filters and allow level trims in precise 0.1 dB increments, ensuring mastering-grade accuracy for every channel. With resolutions reaching up to 352.8 kHz (DXD) and DSD formats, the HAPI Mk III exceeds industry benchmarks for audio performance. Comprehensive AoIP Connectivity and Redundancy The HAPI Mk III excels in audio-over-IP (AoIP) environments, supporting both RAVENNA/AES67 and Dante protocols. Its dual network ports offer redundancy to guarantee reliability during critical operations. Alternatively, these ports can operate in switch mode to connect additional interfaces or devices. With full compliance to protocols such as ST2022-7, ST2110, NMOS, and LAWO HOME, it ensures seamless interoperability across complex networked audio infrastructures. The ZMAN ARM-based audio network module delivers significant performance improvements over its predecessor, supporting extensive workflows with efficiency. Flexible Dante Integration The optional Dante integration allows the HAPI Mk III to interface with over 6,000 compatible devices from more than 400 manufacturers. Professionals can choose between two Dante license options—16x16 I/O or 64x64 I/O—ensuring scalability based on specific needs. Users not requiring Dante can operate the device without incurring unnecessary costs. This adaptability positions the HAPI Mk III as an ideal choice for diverse professional audio environments. Extensive Connectivity and Routing Capabilities Beyond its network capabilities, the HAPI Mk III supports ADAT, S/PDIF, AES/EBU, and word clock connections, alongside two slots for Merging V3 expansion cards. These slots enable up to 16 channels of analogue I/O (mic/line) or 128 channels of MADI + SFP. A forthcoming 64-channel PT64 V3 card will introduce Pro Tools integration by 2025. The internal router manages up to 64 streams, 144 input channels, and 146 output channels, providing exceptional flexibility for signal routing. The unit seamlessly integrates with devices such as the Merging Anubis and Neumann MT 48, as well as Neumann’s AES67 studio monitors, making it suitable for both stereo and immersive 3D audio setups. Advanced Monitoring and Synchronisation For precise monitoring, the HAPI Mk III includes an ultra-low impedance headphone output, accessible from the front panel with both 1/4" and 1/8" TRS connectors. Synchronisation options include LTC, MIDI, and Video Reference via the sync port on the rear panel, ensuring perfect alignment across all connected devices. Reliability, Precision, and Swiss Craftsmanship The HAPI Mk III embodies Swiss precision, with highly skilled technicians meticulously overseeing every step of its manufacturing process. Every component undergoes rigorous sourcing and testing to guarantee exceptional build quality, reliability, and longevity. This commitment to excellence positions the HAPI Mk III as a long-term investment for professional audio environments. The Merging Technologies HAPI Mk III represents the pinnacle of modular audio interface design, offering unmatched flexibility, pristine audio quality, extensive connectivity, and future-ready AoIP compatibility. Whether deployed in a world-class recording studio, a prestigious live venue, or a demanding broadcast environment, it delivers the performance, adaptability, and reliability that professionals require.
