I just put 12v through my dm950 mixer, it should be 9v is there an internal fuse or am i screwed? Thanks

Use 1/4" plug cables or XLR-1/4" cables with the fx loop, depending on the type of connector of your mixer. Don't use batteries, they don't last. Use a type 2 (for noise reduction) 9V wall outlet adapter.

There has to be some internal problem for a fuse to blow. Putting in a bigger fuse can only cause more problems.

It sounds like an adapter issue. The PMI/O say's to use a 9v adapter, but the manual on page 9 says 12v. Try 12v if you use 9v or vice versa.

Powering on while holding the Zoom button will enter a test mode.

To do a reset. Setup>Factory Defaults>SEL>Yes

Probably a fuse ? I have been servicing a lot of Peavey equipment lately and they have some poor circuit designs, a lot of internal un accessible fuses, I might be able to get more info ?

Officially, there is no user servicable fuse, However- there is usually one in the wall wart, which you can check simply by using a voltmeter and sometimes there is one internally. soldered to a small powe buss type of board such as was the case wth an older version of that basic mixer I repaired a number of years ago..

If warranty is not an issue, open it up and check. Just make sure to get all the screws out as nothing needs to be forced apart to open it up- just lots of screws.

hmmm, the back of this mixer is pretty straight forward, you can only plug it in one place!
did you disassemble the mixer and are working with the internal components? those details would be helpful.


if you can post a picture of what exactly your looking at I can probably label it for you so you know where everything goes.

If the fuse blew, you ARE going to need a lot more than a fuse as the cause is usually internal damage to the amp module and or power supply. Replacing the fuse without repairing the cause USUALLY causes more damage.

The internals run on +/-15 Volts and +5 volts. While schematics show the audio and digital circuits they fail to show the power supply. I suspect the supply uses regulators such as the 7815 family so one would want around 18 to 20 volts DC of each polarity.A transformer would likely be about a 28 to 30 VAC centertapped. HOWEVER transformers rarely fail. There should be fuses to protect the transformer. Some Behringer equipment uses a switching supply. Common failures in those is the switching transistor. When testing these units, it is useful to place a 25 watt incandescent lamp in series with the power cord to save fuses and act as a resetable fuse that will send a limited current into the unit for testing.

DO NOT REPLACE A FUSE if it blows. You will do additional damage to the unit internally.

When these blow, there is damage inside that must be repaired before restoring power.

To get an exact replacement fuse holder it is best to get it from Behringer parts. This one has a switch in it depending on which way the fuse carrier is inserted.

assuming that its meant for a 110 outlet then you may want to check the internal fuse the high volatge would have blown the fuse before doing any real damage good luck!
