Troubleshooting
If you think your Mackie product has a problem, please check out the following troubleshooting tips and do your best to confirm
the problem. Visit the Support section of our website (www.mackie.com) to get some ideas or contact our technical support
heroes. You may find the answer to the problem without having to send your Mackie product away.
Here are some useful tips that could correct any of the issues outlined below (or possibly any other issue that we haven’t
yet discovered):
Getting Started:
If you are having any sound (or non-sound) issues, try following the level setting procedure as outlined
on page 7 to verify that all of the volume controls in the system are properly adjusted.
There are no user serviceable parts. If none of these tips work, please refer to “Repair” on the next page to find out how
to proceed.
No Power
•
Our favorite question. Is it plugged in (whether by power cord or battery)?
•
Our favorite follow-up question. If using a battery, is it fully charged? Are you sure?!
•
Another favorite. Is the rear panel power switch in the ON position?
•
Are all the lights out in town? If so, contact the local power company to get power restored.
No Sound
•
Are all the connections good and sound? Make sure all of the connecting cables work and are securely connected
at both ends. Try the same source signal in another channel, set up exactly like the suspect channel.
•
Is the signal source powered on? Is it working (and making union scale)?
Noise / Hum
•
Are you using unbalanced cables? Swap them out with balanced cables to see if that fixes the problem.
•
Turn the input gains down one-by-one. If the offending noise disappears, it’s either that input or whatever is plugged into it.
If you unplug the whatever-is-plugged-into-it and turn the input gain back up and the noise is gone, it’s from your whatever.
•
Sometimes it helps to plug all the audio equipment into the same AC circuit so they share a common ground. Make it so.
