10 Troubleshooting & User Tips
Q. I want to change my Sync Source but it is locked out.
A. To change SYNC SOURCE it is important that audio is not streaming to the interface. The method for
changing Sync Source varies by connection method:
USB – First disconnect USB from the Aurora, then set your SYNC SOURCE, then re-connect the USB cable.
Thunderbolt – Set the SYNC SOURCE from the Lynx Mixer application, or from the Aurora
(n)
Function >
Clock Setup page
LT-HD – The Sync Source should be selected form the ProTools Hardware Setup page or from the Avid
Core Audio/ASIO Manager.
Dante – Typically it is best to keep the SYNC SOURCE set to “Dante”. If you change it to “Internal” or
“Word clock” make sure and select “Enable Sync to External” and “Preferred Master” next to Aurora in the
CLOCK STATUS page within Dante Controller.
Q. I am playing audio from the computer but hear nothing from the Analog outputs
A. Check the following elements.
• Ensure that the Cable connected to the appropriate analog output port is the Lynx CBL-AOUT85 or
adheres to the Tascam DA-88 Analog I/O pin configuration.
• Make sure that the cable connected to your monitoring equipment is plugged into ANALOG OUT 1-8
• Make sure that in the Aurora
(n)
display Function > Routing has the correct source set for TO
ANALOG OUT.
• Verify that your monitoring equipment is turned on and the levels are turned up to a safe listening
level.
Q. Audio plays back at a faster or slower rate than expected
A. This is usually the result of mismatched clock rates and/or multiple clock masters. For example, if you are
playing back audio recorded at 44.1 kHz, but you have set the clock for 48 kHz, the audio will play back
faster and at a higher pitch than expected. Make certain you have set only one device as clock master, all
other digital devices configured to slave, and that the selected sample rate matches the audio source.
For Playback from SD, you cannot play a file that was recorded at a sample rate other than the current rate of
the (n).
Q. I have clicks and pops in my playback
A. Check clock master settings. In any digital audio configuration, there can be one, and only one master
clock, or else you will likely experience audible clock errors. All other digital audio devices must be
configured as slaves to the designated master clock. Since the Aurora’s SynchroLock technology provides an
extremely stable and jitter-resistant clock, we recommend setting the Aurora as the master clock in your
digital audio system. If you choose to use another device as the sample clock master, make sure that the
Aurora and any other connected devices are set to the appropriate clock source setting.
Also, check try increasing the buffer size in your audio application. This parameter is usually in a settings or
preferences menu.
Q. Output is too loud for my monitoring equipment
A. Is your monitoring destination a +4dBu or –10dBV line-level device? Most professional equipment uses
+4dBu as the nominal level, and most consumer equipment uses –10dBV as the nominal level. From the
Function > Analog Trim menu, you can establish the appropriate input and output trim levels in banks of four
for your equipment. At the –10dBV setting, output levels will decrease by 12.2dB.
