Troubleshooting 5.1
Mobile and external digital device are properly
synced. Please consult your external device’s user
manual for details on syncing it to your FireStudio
Mobile.
Flashing Sync Light
The FireStudio Mobile’s Sync light flashes red
and blue when it is not synced. Check the
FireWire cable to ensure that it hasn’t become
disconnected. If you are using an external digital
device, and your Clock Source is set to the correct
digital input, set the sample rate in the Universal
Control to the same sample rate as that of your
master clock. If you are not using an external
device to generate word clock, open the Universal
Control and set the Clock Source to “Internal.”
Audio Dropouts
Audio dropouts can occur when the speed of your
processor cannot process the audio buffers fast
enough. Increase your buffer size in the Universal
Control and try the different Operation Modes.
No Input Signal on Channel 1 or 2
1 Check your mic cable. This should typically be an
XLR connection.
2 Make sure that the microphone does not require
phantom power. If it does, press the 48V button.
Note: Engaging phantom power will place +48V
on both Channels 1 and 2. Be sure that nothing will
be damaged by phantom power being present on
the adjacent channel.
