Merging Technologies PT64V3 – 64-Channel Pro Tools DigiLink I/O Expansion Card for HAPI MKIII

OVERVIEW

Seamlessly Connect Pro Tools to Networked Audio

The Merging Technologies PT64V3 is a professional 64-channel Pro Tools DigiLink I/O expansion card designed specifically for the HAPI MKIII. It provides direct, ultra-low-latency connectivity between Avid Pro Tools HDX or HD Native systems and professional RAVENNA/AES67 or Dante audio networks, allowing studios to combine the power of Pro Tools with Merging Technologies’ renowned audio conversion and networked audio ecosystem. Featuring two Mini DigiLink connectors, the PT64V3 supports up to 64 channels at 44.1/48kHz, 32 channels at 88.2/96kHz, and 16 channels at 176.4/192kHz.

Designed for professional music production, broadcast and post-production, the PT64V3 enables users to take full advantage of the HAPI MKIII’s premium microphone preamps, A/D and D/A conversion, while integrating seamlessly with Pro Tools workflows. It also provides direct access to the advanced monitoring capabilities found in Merging Technologies ANUBIS and the Neumann MT 48, making it an excellent solution for immersive monitoring, personal cue mixes and complex networked studio environments.

Supporting Automatic Delay Compensation, multiple hardware emulation modes and scalable multi-card configurations, the PT64V3 is equally suited to small studios and large production facilities. Install up to two PT64V3 cards in a single HAPI MKIII for up to 128 DigiLink channels, or build even larger HDX systems using multiple HAPI units for exceptional flexibility and performance.
