All Legacy Mobile I/O ULN-2's can be upgraded with a 2d Card. The 2d card ships with a new ADAT/Optical I/O board that adds Optical I/O to the unit as well as a new back panel.

If you want to upgrade your existing Mobile I/O to a 2d Expanded unit, we recommend taking advantage of our Factory Install service. You ship your unit back to Metric Halo, and we will install the 2d Card in your box, install the firmware, test everything, apply any factory updates to your unit and ensure that you box is operating at factory spec.

The factory install service is available from Metric Halo in the US at the MH Custom Shop, where they will be happy to install your 2d Card and v.5 software. The 2d Card and installation is available outside the US from our distributors around the world.
