Im thinking about buying a djx750 and have rokit 5 monitors. would this work? what is the best way to connect them, to have good sound? it is just for a home dj setup, all on one desk, two cd decks, mixer & the rokits. will it produce good sound?

What you are describing is a total component failure of something in the crossover board. You cannot really check a crossover without an oscilloscope and a frequency generator. In a lot of cheap speaker systems, there is no crossover board attached to the woofer. In your case it appears that a low pass filter is present on the woofer. http://circuitdiagram.net/loudspeaker-system-crossover-network.html

sounds like pre-amps or audio chips gone.

Line level output of the mixer would go into the line level inputs of the EQ, and the EQ line level outpputs to the line level inputs of the amplifier. If you are faced with a mix of unbalanced inputs or outputs, to balanced inputs or outputs it gets a little complicated because you need to matrix the balanced signal to unbalanced load and vice versa. There is no single answer to doing this either.

RCA jacks are unbalanced, 2 conductor 1/4 inch connections are unbalanced most of the time. XLR and 3 conductor 1/4 inch jacks and plugs can be either balanced or unbalanced.If either are wired so left and right are a single ring or tip on the 3 conductor 1/4 inch jack, it is unbalanced and they would share a common ground lead. XLR wired with one pin common with shield and right and left have a single conductor on the plug or jack, that is unbalanced.

Try swapping the monitors inputs. if the other speaker starts popping on the same output it'll show that the mixer may have a problem. otherwise return for repair.below is a link to the manual. check out the troubleshooting section pg 13

Sounds like you have a problem in the amplifier section. Could be a bad capacitor or a floating ground. As a charge builds it will create the hiss and when it discharges, it surges through the amp causing it to shut down. You'll probably want to send them in for service.

Make sure channel(s) are assigned to stereo output

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.

Since the mixer has a line level output, yes you can use a home stereo for the "AMP". Use the AUX IN, TAPE IN or CD IN on the stereo and connect the speakers as you normally would.

i have djx750 mixer, and i want to connect speakers to it,but the cable for the speakers are guitar jack leads and back of mixer are scart can i get a cable with guitar jack and scart on same lead??cheers

Look for a failure in the power supply section. You will need electronic experience or someone who has that.

If the fuse is glass and blows silvery inside thia means a direct short inside. SUSPECT the input rectifier or filter capacitor(s).

Do testing with a 100 watt light bulb in series with the hot side of the power cord to avoid blowing fuses.
