Apollo Software Manual Chapter 12: Device Drivers 185
Driver I/O Tables
The tables in this section list the I/O numbers and names for all Core Audio streams
available at default Core Audio Panel settings.
Note: All available driver I/O channels and names are also listed within Apple’s
Audio MIDI Setup application which is included with Mac OS X at:
/Applications/Utilities/Audio MIDI Setup.app
Tip: Each table is on a single page. For convenient reference with DAWs that don’t
display driver I/O channels by name, print the sheet for your particular setup.

• All tables apply at all sample rates unless “4x Sample Rates” is noted.
• “1x sample rates” is defined as 44.1 kHz and 48 kHz.
• “2x sample rates” is defined as 88.2 kHz and 96 kHz.
• “4x sample rates” is defined as 176.4 kHz and 192 kHz.
