- A maximum of one Apollo Solo or Arrow can be used in a single system
- Any UA Thunderbolt device combined with Apollo Solo or Arrow must be Thunderbolt 3, as the Apollo Solo is bus powered and the devices need to be on the same Thunderbolt bus.
- A maximum of four Apollo Thunderbolt interface models can be connected together (mix-and-match). Arrow devices will also count toward the maximum limit of four.
Note: Apollo Solo USB, Apollo Twin USB and Apollo/Apollo 16 FireWire connections cannot be combined with Apollo Thunderbolt connections - UAD-2 Satellite (Thunderbolt, FireWire, USB) and UAD-2 PCIe cards can be combined with each other and Apollo Solo.
- A maximum of two UAD-2 Satellite USB devices can be connected (Windows only)
Note: All compatibility requirements for UAD-2 Satellite USB still apply when used with Apollo Solo - A maximum of two UAD-2 Satellite FireWire units can be connected
Note: All compatibility requirements for UAD-2 Satellite FireWire still apply when used with Apollo Solo - A total of six UAD devices can be combined in one system
(Apollo Thunderbolt, UAD-2 PCIe, UAD-2 Satellite FireWire, UAD-2 Satellite USB, or UAD-2 Satellite Thunderbolt)
