Check the Fast Track C400
Drivers
While it is technically possible to use your
Fast Track C400 as a class-compliant interface
(using the drivers already built into the com-
puter's operating system), we advise against
this, as it does not provide the best perfor-
mance or complete access to all of the prod-
uct's features (such as monitor mixers or
Control Panel). We suggest that you down-
load and install the latest drivers from the M-
Audio website at www.m-audio.com/drivers.
If this does not resolve the issue, check to see
if the Fast Track C400 drivers are properly in-
stalled:
Windows Vista and Windows 7
• Go to the Windows Control Panel, double-
click the Device Manager icon, and then:
• Click the plus sign (Windows Vista) or tri-
angle (Windows 7) next to “Sound, video
and game controllers,” and locate the
Fast Track C400 listing.
If you see a question mark or exclamation point
next to it, or if it is not listed, try using a differ-
ent USB cable and/or USB port on the host com-
puter. If you still see the question mark or excla-
mation point, you may need to reinstall the
drivers.
Music Software Configuration
Make sure your music software has been con-
figured for use with Fast Track C400.
Windows
• Open the Sound Control Panel (Windows
Vista and Windows 7), and make sure Fast
Track C400 is set as the Default Playback
device.
• Check the audio preferences page in your
music software to see if the correct ASIO or
WDM drivers are selected.
Mac OS X
• Go to System Preferences > Sound, and se-
lect Fast Track C400 under the Input and
Output tabs.
• Open the audio preferences page in your
music software to see if the correct Core
Audio drivers are selected.
If Fast Track C400 is correctly installed and
configured for your music software do the fol-
lowing:
• Check the signal path to make sure the out-
puts are routed to your headphones, ampli-
fier, or powered monitors.
• Ensure that the Output Selector switches
are set so that corresponding line output
pairs are not muted. (The LEDs correspond-
ing to the line-outputs for your speakers
should be illuminated).
• Ensure that the Volume Control knob is
not turned down (fully counter-clockwise)
otherwise your outputs will be muted.
• Ensure that the Monitor Mixer in the Fast
Track C400 Control Panel software is set
correctly and that the outputs are not
muted or turned down.
• Try using a different USB cable and/or USB
port on your computer.
