Factory Installed 2d Card for 2882. All Legacy Mobile I/O 2882s can be upgraded with a 2d Card. The 2d card comes with a new ADAT/Optical I/O board that replaces the existing board in the unit. If you want to upgrade your existing Mobile I/O to a 2d Expanded unit, we recommend taking advantage of Metric Halo's Factory Install service. You ship your unit back to Metric Halo, and they 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. This item order initiates that process. Order today. 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.
