20 Most Recent Mackie CFX 12 mkII 12 Ch. Compact SR Mixer w/Effects Questions & Answers


Where are you getting the low output? It would be very strange if all channels failed in the same way so it is probably something common to them all. Can you get the clip light to illuminate at all by turning the gain up on a mic channel and shouting into the mic? You are referring to the gain at the top of the strip not the slider aren't you? What happens if you assign a channel to the other sub channel, does the level come up through that? What happens if you take the output from the aux send and you send signal there, is it the same issue?
I may be completely wrong but I suspect if it is only mics that are causing a problem you may have the routing set up wrong or not set a level somewhere else right.

Assuming if you pan hard left on an input it comes out the left and panning hard right goes nowhere and as you say the tape input feeds through to both sides OK there is a very limited number of places where the problem can be. If you are confident open it up and check all the connectors and cables. If anything has come loose this may find it, otherwise it's a trip to the repair shop. The largest cost will be the taking apart and putting back together as the repair itself should be a simple one and diagnostics easy.

What makes you think the effects chip is bad? It is LIKELY a fine-pitch DSP that is far beyond what the average tech could do. If you could get one, you would have to take this to a shop specializing in surface mount rework. The chances of this chip being bad is very low. More probable is either pilot error or other circuits, especially those exposed to the external connections.

Sorry, I have looked at the schematics and the TAPE IN jacks are mixed into the MAIN outs AFTER the insert jacks, so your subs will NOT receive signal via the insert from the TAPE IN jacks.
You could make a small passive mixer merging the TAPE/CD before going to the crossover. This would require some non-standard cabling.... The other option is to run the CD into a regular stereo channel rather than the TAPE IN jacks... then the CD will go through the insert/crossover and to the subs as you desire. The last option is to use the crossover at the MAIN outputs instead of as an insert... which would be the CONVENTIONAL way... use BALANCED cables wherever possible.

You probably have issues with caps in the power supply....I would check that first...open it up and look for buldging caps and replace any that you find....

First thing to do is get a can of contact cleaner. Take off the knobs and spray it into the reostats below. Spray into all the switches and even into the sliders. Move everything back and forth - 0 to 10 (to clean them). If we're lucky, that will fix it.
Good Luck

First, unless you are a trained or self-taught audio technician, don't attempt to repair the unit yourself. Let the professionals repair it. You can damage it beyond repair if you don't know what you're doing.

Non-working channels are caused either by bad connections, bad solder joints or a dead IC op-amp.

The causes of weak channels can be more challenging to track down. I'd suspect bad connections, dirty controls or connectors.

Glenn, Does it say 'overvoltage', or simply 'voltage'? For the clearest result brother, contact Mackie - 1-800-898-3211 is their tech line - they're super cool - I just always picture the guys at Mackie sitting around reading comic books and shooting guns into the air. good luck!
