Know before you buy
Yes, this interface requires a Thunderbolt 3 port to function. While it is compatible with both macOS and Windows, please ensure your computer has a native Thunderbolt 3 port, as standard USB-C ports will not provide the necessary bandwidth.
The onboard QUAD Core DSP is primarily designed to power UAD plugins during tracking with near-zero latency. While you can use these plugins during mixing within your DAW, the processing power is limited to the interface's internal chips rather than your computer's CPU.
Unison technology allows the Apollo's mic preamps to physically reconfigure their impedance and gain staging to match the characteristics of classic analog hardware. This means you can track through authentic emulations of vintage gear in real-time, capturing the color and texture of high-end studio equipment.
Yes, you can expand your input count using the TOSLINK optical port. By connecting an external preamp with ADAT or S/PDIF output, you can add up to eight additional digital input channels to your setup.
Yes, the interface provides +48V phantom power, which can be toggled on or off individually for each of the two XLR/TRS combo inputs via the front panel or the control software.
Absolutely. Its compact form factor and durable build make it an excellent choice for project studios or mobile recording. However, keep in mind that it requires an external power adapter and a stable Thunderbolt 3 connection to operate.
