Metric Halo MH EdgeCard - 4x ADAT — an EdgeBus expansion card adding four ADAT ports and 32 channels of I/O total to any 3d-based unit.
The card occupies the single EdgeBus slot present on every 3d-based unit and brings in four independent optical ADAT links at 8 channels each, delivering a full 32 channels of input and output on one expansion card without patching together several individual optical ports from separate modules.
32 ADAT Channels Without Stacking Individual Ports
Expanding a system with ADAT converters — extra preamps, input racks, other interfaces with optical ports — usually means connecting successive individual TOSLINK pairs to separate expansion cards, which gets cluttered fast once several sources are involved. The 4x ADAT card concentrates that function into one EdgeBus slot, offering 4 ADAT ports (8 channels each) on a single card — enough to connect several outboard preamps at once without taking up additional expansion slots on the unit.Scaling Mic Inputs Without Replacing the Converter
A studio that has hit the limit of a 3d unit's built-in mic channels can extend the system with outboard preamps carrying an ADAT output instead of investing in a second full interface. All 32 channels on the card land in the 3d unit's routing matrix on equal footing with the built-in I/O, so the additional ADAT sources are available in the same DSP processing path and the same mix session as the factory mic channels, with no separate interface to manage.KEY FEATURES
