Metric Halo 3d Card for ULN-8/LIO-8 — a hardware-and-software upgrade replacing the entire digital section of an existing ULN-8 or LIO-8 with the 3d Core architecture, including MHLink, EdgeBus, and USB-C.
The card replaces the unit's older digital and computer interfacing module with a modern implementation while leaving the analog section and preamps untouched — the owner keeps the characteristic sound of their ULN-8 or LIO-8 while gaining current connectivity and the full 3d software suite. Installation is user-performed in the field, with no need to ship the unit out for service.
An Older Interface Without Losing the Preamp Investment
Replacing an entire unit just to gain modern connectors and routing means writing off money already invested in a ULN-R preamp configuration. The 3d Card solves that surgically — it modernizes only the digital and computer layer, leaving the analog front end untouched. Once installed, the unit gains class-compliant USB-C, very low-latency MHLink over Gigabit Ethernet, and an EdgeBus slot accepting SPDIF, AES, ADAT, and MADI cards that the older platform never supported.A Full Software Suite, Not Separate Licenses
A digital upgrade without matching routing and mixing software has limited practical value. The 3d Card brings a complete set: MH Console as a 64-bit routing application, MH Mixer with 128 inputs and 64 busses at zero latency, MH MonitorControl with analog-domain monitor control, and MH Record as a 128-input multitrack recorder deeply integrated with the hardware. A +DSP license with over a hundred plug-ins is included in the upgrade, with no additional licensing fees.KEY FEATURES
