Troubleshooting
If you think your DC16 has a problem, please check out the following troubleshooting tips and do your
best to conrm the problem. Visit the Support section of our website (www.mackie.com/support) to get
some ideas or contact our technical support heroes. You may nd the answer to the problem without
having to send your DC16 away.
Here are three useful tips that could correct any of the issues outlined below (or possibly any other issue
that we haven’t yet discovered):
(1) — Restart the iPad. Don’t just restart the Master Fader app. Restart the iPad! Completely power it
down, then power it back up.
(2) — Restart the DC16 and DL32R. This is especially useful after rmware and software updates where the
mixer and iPad aren’t quite on the same page. A simple reboot can sometimes work great wonders.
(3) — Restart the router. Internet disconnectivity got you down? Unplug and re-plug the router.
This may resolve any connection issues.
There are no user serviceable parts. If none of these tips work, please refer to “Repair” on the next page to
nd out how to proceed.
No Power
• Our favorite question. Is it plugged in? Make sure the AC outlet is live [check with a tester or lamp].
• Our second favorite question. 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 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.
• Are you using unbalanced cables? Swap them out with balanced cables to see if that xes the problem.
• Turn the input gains down one-by-one. If the oending 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.
• Is phantom power required for the microphone?
• Sometimes it helps to plug all the audio equipment into the same AC circuit so they share a
common ground. Make it so.
• Has the band been together long?
