With a Thunderbolt Option card in the Apollo interface you can run many more UAD plugins with lower latency and get improved performance at higher sample rates.
The card is equipped with 2 Thunderbolt ports so you can easily daisy-chain other Thunderbolt devices such as hard disks and monitors.
The Thunderbolt 3 Option Card for rackmount Apollo audio interfaces allows music and audio producers to connect their Apollo directly to compatible Mac or Windows systems using Thunderbolt 3. This user-installable card offers two Thunderbolt 3 ports, and provides 15W bus power to all downstream Thunderbolt 3 peripherals – perfect for daisy-chaining additional Apollo interfaces and UAD-2 Satellite DSP Accelerators, modern storage solutions, 4K displays, and more.
