Behringer DJx700 5-Channel Pro DJ Mixer with Digital Effects & Bpm Counter - Answered Questions & Fixed issues

Actually, you may be in luck. A burned cap means that it has done exactly what it's supposed to do. So...you might stick an identical one in there -- it's a 0.1 uF cap, and you can find these at Radio Shack (0.1 uF 50V) or online. They are cheap, so give it a shot.

Behringer only gives schematics to their authorized service people.

I find I can usually trace stuff out as needed as the mixers are a very symetrical repeating circuitry.

Most components are readily available from other sources.

If it goes back to normal after you shut it off and letting it sit for a bit, it's related to heat buildup. If that's the case, it's either a component failing or a cold solder joint that opens when a part expads/contracts from itr's contact point. Either way, you needto take it to the repair shop.

Can you elaborate a bit more about what you mean by "turning off?" What are you doing up until that point? Does it do it at certain times, etc.?

Check that all the eqs are set not to cut bass, check there are no effects on and that the XPQ is off. If you still have the problem how sure are you there is no bass coming from the mixer? Have you tried it with another amp? We had one hire customer who had the same problem you describe and his amp had a crossover and it was set to act as a mid/top amp and wasn't giving him any bass, unsurprisingly, switching it back to full range sorted it.

The first thing I would look at is the kill switches on each side, make sure these are not pressed. Also make sure the master fader is up. I would disconnect anything that may be plugged into the effects loop send and return. Make sure the main outs are plugged in correctly, the main master outs should go to a power amp, this unit appears to be a unpowered unit. Make sure you are using the proper cables to avoid damage, lookup and understand the difference in speaker cords and instrument cords and place them properly. Also make sure the "assign A" and "assign B" are positioned correctly. Hope this helps but, if you give me a little info on how you are using this unit, I could help you further, please.

I suspect one end of the crossfader pot has broken from the element. The fader probably costs less than $5.

You likely will have to remove all the knobs and some screws to seperate the board with the fader from the front panel so you can replace the fader.

VERIFY the pot is bad with an ohmmeter before dis-assembling however.

You MAY be in luck. It looks like the cross fader has a connector which MIGHT allow you to remove it or certainly only a small board for replacement, seeing these take abuse.

It appears that the cross fader is a dual 100K type B taper.

Most likely internal fuse for effects module has blown. look inside the mixer for the blown fuse (it'll be near the bit that's not working) and replace with a fuse of the same rating,

Behringer fired their USA distributed a few weeks ago. You'll have to call Behringer directly and request the part. Or email.goto th website

The poower cord is a standard three wire power cord that is used on most computers and other equipment. The cord RARELY fail. You may have some other problem.

The crossfader is to gently fade from one source to another. If you only have one, the crosfader isn't useful... it would act like a plain fader with one side being dead and the other at full volume.

the faders were actually fails functioning it well, it must be replace a new one!im a audio technician of BEHRINGER!

You are probably overdriving the inputs. You haven't told us the source of the inputs and we can't guess where they may come from. You need to read the manual and make sure your source outputs are within range of what this unit requires.

Transformers rarely fail... you wasted money on that... Likely one of the rectifier diodes/module or filter caps has shorted. Continued use will burn out the transformer. It is humming because it is overloaded with failing components.

is there power to it? does sound come out of it? if not it could be fried or about to fry. Behringer makes low end products, which tend to break fast. if you dont have any sound or lights chances are its unfixable

The LED looks like it is a simple switch closure...

Here is your schematics:

Scroll down and wait for a link "Get Manual" that has something like "two downloads per day" if not registered... and click on the link to get your schematic... The schematics are NOT that easy to understand as the switches are NOT labeled with their function so you have to do some head scratching to figure them out.

Look on the switch for a brand name... often they use a lot of ALPS products. I normally search DigiKey.com and Mouser.com, and Allied electronics and Newark.com.

Behringer online is of little help. I have called them and got parts directely. They don't stock a lot and sometimes it takes a little while to get the product.

Sounds expensive. How did the Canadian plug fit a UK socket? The fuse won't have blown fast enough to avoid all damage. Their coucld be an internal fuse - see instruction book. It won't be a home repair job it its not the internal fuse - sorry.
