Apogee interfaces are only able to communicate with one computer or iOS device at a time. It is possible to route the audio from an Apogee interface connected to an iOS device into an Apogee interface connected to a Mac. The USB-A Port on the back of Duet-iOS and Quartet-iOS is only for MIDI data, and cannot be used to pass audio.
ONE for Mac (first generation) offers a choice of two sample rates, 44.1kHz or 48kHz. So, what’s the best sample rate to record your project at? It’s a good idea to avoid unecessary sample rate conversion stages, so the answer is determined by the sample rate of media on which you plan to distribute your recording. If the final distirbution media is CD, record at 44.1kHz. If the media is video or TV, most often 48 kHz is the best choice. If you’re part of a larger production chain, and aren’t sure, ask whomever is responsible for assembling the final product – they’ll undoubtedly appreciate the forethought.
ONE for iPad & Mac (second generation) offers a choice of four sample rates: 44.1kHz, 48 kHz, 88.2kHz or 96kHz.
Any Apogee product that includes microphone inputs with 48v phantom power is designed to handle loads up to a complete short, or 14.1 mA. This will properly power any microphone.
