For quick real-time feedback on actual usage, hover the mouse pointer over their respective labels on the UAD Meter. The pop-up indicator shows data for each DSP chip, and will even respond to settings changes if you have DSP LoadLock activated. Pro presets UAD has many top-level endorsees, and their more recent classic 'Collection' plugins have included presets from some of them. These presets can serve as good starting points, or they can simply offer insight into the settings that top-level mixers and engineers would use in particular scenarios. Powering on through One slight frustration for Apollo and Apollo Twin users is that they're not bus-powered by your Mac, either in FireWire (Apollo) or Thunderbolt (Apollo and Apollo Twin) formats. What's more, the dual FW800 ports on the back of the Apollo can't provide bus powering to peripherals such as hard drives. However, what you may not have realised is that the Thunderbolt expansion for Apollo does carry power (7 Watts) for powering further Thunderbolt peripherals, which can help to keep your setup streamlined.
