In 2001 Metric Halo introduced the Mobile I/O 2882 and called it “Future Proof”. While the competition has obsoleted multiple generations of products, the 2882 is still arguably the best FireWire interface in its class available on the market. In 2003, they released the ULN-2, with the finest preamps available in any interface, (until they developed the ULN-R mic pres in the ULN-8). With the release of the 2d Card and v.5, Metric Halo delivered yet again on their commitment to making “Future Proof” products that stand the test of time.

The 2d Card was introduced in 2008 as a massive hardware upgrade for Mobile I/O 2882 and ULN-2 interfaces (without the 2d card these are known as "Legacy" units). All 2882 and ULN-2 interfaces manufactured since are known as "2d Expanded" units. The ULN-8 and LIO-8 were designed after the 2d card, and were built around it.

The 2d Card greatly enhances the DSP processing power of the original 2882 and ULN-2, adds a brand new ADAT implementation and also improves the clock of any unit into which it is installed. Of course, the ULN-8 and LIO-8 possess these features (while trading eight channels of AES I/O for the ADAT ports).

All 2882 and ULN-2 interfaces that did not ship with a 2d card from the factory can be upgraded. You may choose to send your unit back to the factory to have the card installed or may do it your self. We recommend watching the installation videos for the 2882 and ULN-2 to determine if you are comfortable performing the upgrade yourself. All LIO-8 and ULN-8 interfaces contain a 2d card.

Along with the 2d card Metric Halo introduced version 5 of their MIO Console software. MIO Console is the software "front end" for all of their interfaces. While other manufacturers churn you with the special of the day, Metric Halo builds products that preserve your investment and deliver for you year after year and project after project. It is their philosophy and they take it seriously.
