Metric Halo MH EdgeCard - 1xSPDIF 2xADAT — an EdgeBus expansion card combining one SPDIF channel and two ADAT ports, delivering 18 channels of I/O total from one slot.
The card occupies the single EdgeBus slot present on every 3d-based unit and offers 16 channels of ADAT across two pairs of optical connectors plus 2 channels of SPDIF on an RCA pair — a middle-ground variant between a pure ADAT card and a dual-SPDIF module, for systems where a single consumer input is plenty.
16 ADAT Channels With a Spare Consumer Input
Expanding with outboard preamps or ADAT converters rarely calls for more than two optical ports per unit, and most racks have at least one device with an SPDIF connector — an older synth, a reference player, a home console. This card covers both cases from one slot: 16 ADAT channels across two ports handle the main mic or line expansion, while a single SPDIF channel stays in reserve for gear that has nothing else to offer.A Simpler Card Choice for Moderate System Expansion
Rather than fitting a card with a full two SPDIF channels where the second pair would go unused, this variant matches the consumer-input count to actual need while keeping the full 16 ADAT channels where they're actually useful. All 18 channels land in the 3d unit's routing matrix on equal footing with the built-in I/O, so the configuration stays flexible without losing access to either format.KEY FEATURES
