AMBus FireWire card – User’s Guide
Working with OS X
1. Thanks to the class compliant FireWire driver in Apple’s OS X, no drivers need to be installed.
2. After installing the AMBus FireWire card in the host interface and connecting the card to your computer,
open the Audio Midi Setup utility, found on an OSX Macintosh here: Applications/Utilities/Audio Midi
Setup.
3. Click on the Properties For drop-down menu and select Apogee FireWire (xxxx) (the serial number of
your card appears in parentheses).
4. Verify that the host interface sample rate matches the sample rate indicated in the Format field.
5. If the OS X audio application you’re using doesn’t have a sample rate parameter, the sample rate of
the system is determined by the setting in Audio Midi Setup. Applications that fall under this category
include Apple iTunes, Apple Quicktime and other “audio utilities”.
6. If the OS X audio app does include a sample rate parameter, the audio app setting determines the
system sample rate and transmits the rate to AMS. Apps that fall under this category include Apple
Logic Pro and other professional digital audio workstations (DAWs).
7. Thus, if your app includes a sample rate parameter, change the rate from the app; if your app doesn’t
include a sample rate parameter, change the rate from AMS, as described in steps 2-4. In both cases,
set the Apogee interface sample rate from the interface’s front panel.
