Metric Halo MH EdgeCard - 2xSPDIF 2xADAT — an EdgeBus expansion card combining two SPDIF channels and two ADAT ports, delivering 20 channels of I/O total from one slot.
The card occupies the single EdgeBus slot present on every 3d-based unit and puts both consumer SPDIF input and multichannel ADAT ports on one module — a fit for systems bridging equipment of different generations instead of fitting two separate cards per format.
Two Digital Formats Without Two Separate Expansion Cards
Studios built up over years rarely run a single digital format — alongside newer ADAT converters there's often an older CD player, synth, or home console with SPDIF-only output. The 2xSPDIF 2xADAT card solves this with one EdgeBus slot, combining 2 SPDIF channels on RCA with two 8-channel ADAT ports for 20 channels total, avoiding a choice between formats or fitting a second card into a slot the unit doesn't have.Flexible Configuration for a Changing Equipment Park
Rather than buying a separate SPDIF card and a separate ADAT card for two different 3d units, one 2xSPDIF 2xADAT module covers both scenarios on a single device — useful in mobile work where the connected gear changes from session to session. All 20 channels land in the 3d unit's routing matrix on equal footing with the built-in I/O, so SPDIF and ADAT sources can be mixed in the same session without rerouting signal through an external format router.KEY FEATURES
