SOURCE: No Volume oe sound coming out of speakers

try connecting speakers to another sound source or if you have access to a ohm meter, check impedance of speakers, should measure 4~8 ohms.

SOURCE: My behringer djx700 5 channel pro dj seems to have

Hello,

It doesn't seem like a typical "feedback" problem, as feeback is produced by over modulation between the amplifier and the source - usually a pickup or microphone. It may be your cables to your amplifier are bad, or the actual line out jack(s) may have gone bad. If it is more of a humming sound rather than feedback, that is most likely your issue. If you have additional patch cables, switch out the existing ones, and see if that ends it. If not, it is possibly the jack(s).

You have a headphone jack on the Behringer, though you did not say if the problem arises through the headphones or an external amplifier. If you get the noise in the headphones, when no patch cords or a mic is attached, then the problem you should look at is your headphones or the headphone jack. You can narrow the problem down by using an external ampifier and see if you still have the "feedback" sound. if not, it's in the headphones or headphone jack.

Please try and provide more information for this question if we are unable to track the problem with these suggestions. As we do try very hard to center in on customer's problems, we do ask to provide as much information as possible, so that we can facilitate your resonse more effeciently.

Thank you for using FixYa.

SOURCE: I have Behringer PMP 3000 2 channels not working

Fan speed depends on temp sensors. If doesn't run at all when unit is loaded, take in for repair immediately.

If FX window changes with the control, chances are you have not set the controls properly. You need to havew THREE places turned up for effects: The FX knob in the desired channel(s), The FX slider and finally the knob to send the FX to the mains and/or monitors.

OFTEN the stereo channels aopear to not be working because of the A/B switch between the RCA and 1/4 inch jacks.

You did not give me enough info regarding which channels appear to not work.

SOURCE: I own a Behringer Ultratone

This is most LIKELY an electronic problem... possibly in the final power amp. Repair may be a simple failed component or a mass number that fail like a stack of dominos. Take it to a shop for repair.

SOURCE: HOW TO WIRE GEMINI GRAPHIC EQ 3000 TO behringer djx750 proffessional MIXER

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.

Where can I get a Type T 6.3 AH 250V fuse for a K3000FX 300Watt Keyboard Amp?


Start with a 5 amp fuse and see if that holds. If it doesn't go to 10 amp. If that pops, you will have a power supply or amplifier fault. Good luck

Quits working, but a very loud note or sound will break through and will start working for a while longer.. Like a squelch on a cb radio.


Sounds like a dry joint, if you're brave it may be worth going inside and flexing things to see if you can find it and then fix it if you're any good soldering.

No woofer sound from my K3000FX. Verified all cables and settings correct- but sound only comes from tweeter. What could it be?


Step 1:

Hate to say it, but possibly a blown speaker. To check this, do the following -


Step 2:

Insert headphones into jack to verify for sound there.

Step 3:

Unplug unit and open rear panel to reveal speakers.

Step 4:

Remove leads from woofer.

Step 5:

Using a multimeter, set to OHM (horseshoe) to lowest setting.

Step 6:

Apply red(+) and black(-) to speaker leads. Meter should read at least 4-8 ohms of resistance.

Step 7:

If no reading, then voice coil is blown.

Step 8:

If no meter available to use, the use a 9 volt battery by applying direct connection to speaker leads in an off-and-on fashion - You should hear a "click" sound come from speaker. If no "click," then speaker is blown.

Step 9:

If click is heard, and resistance on meter is correct, then the amp circuitry leading to the woofer may be blown = repair needed.

Will an Eminence Beta 15A speaker (`5", 300w, 8 ohm) fit/work in the k3000fx? If so, will there be a trade-off or consequence of performance? I already own the Beta speaker, and have a chance to...


It ill probably work, however I have had to do body-and-fender work on a speaker cabinet where the new frame would not quite set in the existing hole in the mounting board. The Eminence speakers are supposed to be good... are you sure the Behringer amp is OK? The K1800FX uses a conventional linear amp... not sure about the K3000fx... The only possible problem I could see is that the original speaker (Bugera 15 inch)may have a different response and the tweeter may not match too well. You can probably adapt using th EQ should this be the case.

My ultratone k3000fx does'nt sound anymore. What can be the problem ? Thank you.


Here is your service schematic:

http://elektrotanya.com/behringer_k1800fx.zip/download.html

Scroll down to "Get Manual" and click on it to download. The file is compressed and the preamp/FX is on one, the power amp on a second, and a trivial tweeter crossover on the third... I did not see the power supply. Check speaker for continuity of voice coil. Else it is likely a power amp failure.

Hello! I recently bought used Behringer EQ 700, but it's not working. Baterry is ok, the red ligh is burning, when I press the pedal, but no sound is coming through, even when its not on. What could be...


The red light means NOTHING regarding the battery condition... If battery is not new, try a new one.

I have seen several problems... some people get the cables backwards for input and output. The INPUT cable is what turns on the battery and it has to be a mono cable.

ANOTHER common problem with ABUSED pedals is that the jack used for external power adapter gets smashed at some point and cracks the circuit board near it. USUALLY the light will not come on when this happens.

Byond this, it probably requires repair. Some are easy to open and others are a bear to get the circuit board out... key is to NOT force very much when working on these.

Often they will just double up with two amps, one inverted, and use in bridged mode.at the higher power in what we call an "H" arrangement.

Since the drains are tied together, the heatsinks MIGHT be hot output level.
