ABOUT: Connector mapping and input/output configuration for Deltacast 12G/4C cards

The Deltacast card included in the M|8e, M|8i, M|4e and M|4i bundles is the DELTA-12G-elp-h 4c card. It supports:

• in HD, up to 8 channels of 1080p60
• in 4K, up to 4 channels of UHD60p
• in 8K, up to 1 channels of 4320p60 [8K] using Quad Link (SQ)

This card has 8 connectors in total:

• 4 of them are 3G connectors, which support HD only
• the 4 others are 12G connectors, capable of 4K resolution [or 1 combined 8k]

Thunderbolt Chassis Limitations (M|8e and M|4e)

The M|8e and M|4e bundles use a Thunderbolt expansion chassis, connecting to any Mac via Thunderbolt 3. This means that the card will be limited to the bandwidth of the Thunderbolt, and you won't be able to use the 4 channels of 4K60. Make sure to check the tech specs  page of the bundles to know the maximum number of channels.

The M|8i and M|4i consist of the Deltacast card along with the required software licenses on a dongle. These are designed for installation in a Mac Pro, enabling full-speed performance without any Thunderbolt-related limitations

Cabling guides

Although the same card is used across all bundles, orientation may differ: the card may appear upside down when installed in a non-rack mount Mac Pro.

4K Usage Warnings

Only connectors 1, 3, 5, and 7 support 4K signals.

However, connectors work in pairs:

• Connector 1 pairs with 2, 3 with 4, 5 with 6, and 7 with 8
• So for example, when using connector 1 in 4K, you must not enable connector 2
• Doing so may interfere with signal integrity

You can still create mixed-resolution configurations. For example, use connector 1 in 4K, and connectors 3 through 8 in HD.

• Extra note when using a Thunderbolt 3 chassis: The max number of channels in 4K will be 4 channels of 4K30, or 2 channels of 4K60. To capture 4 channels of 4K60, you’ll need a full-bandwidth PCI Express slot in a Mac Pro.

8K Usage Warnings

Only connectors 1, 3, 5 and 7 combined support 8K Quad-Link (Square Division) input.

To setup 8K in MovieRecorder:

• Enable only input 1. Enabling any other inputs (2, 3, 4, 5, 6, 7 or 8) may compromise signal integrity.

• On Input 1, open Source Settings, disable “Automatically detect input format,” and manually select the 8K resolution and frame rate under Video Format.

• Extra note when using a Thunderbolt 3 chassis: The max resolution will be 8K 30 fps; to capture higher framerates up to 8K 60 fps, you’ll need a full-bandwidth PCI Express slot in a Mac Pro.
