Flashing 88 Hi, I have a behringer euromixer, the fx display is sporadically flashing 8 with a ticking sound. Other than that the unit works fine....any fixes?

Try putting guitar trough the FX Loop, if there is still no sound, you may have a problem with the Power Supply.

you have to set three gain controls to pass the FX into the mix. The FX send gain for each input channel, the FX fader which sends the FX mix to the effects unit, and finaly the gain that sends the FX output to the mix. Depending on which effect you choose, some are very subtle.

Hi,

Sounds very much like the control knob is dirty, needs a good cleaning!

Sometimes just giving the knob a good exercising (turn it up and down quickly a few times) can help it.

Some cleaners can leave behind a residue and make it worse, so ask at an amp repair place what product is best to use.

Hope this helps!

Check the 5 volts to the FX unit, If the voltage is low, the FX processor will keep reseting generating clicks, In a different product, the 5 volt filter cap was degraded and voltage dipped down to 4.5 volts causing resets.

This is likely a problem with the FX in the unit or the power to it. Does the FX display act correctly? Check that the headphone source "Main Mix" is the ONLY button down for the headphones. If not, make it so. If the clicking is still there, try the headphones in the aux send jacks... see if EITHER left or right can hear the clicking. Back in the phone jack, scan across the SOLO channel buttons down one at a time. Is there clicking? If not, the problem involves the mixing buss or further down the line. Make sure the SOLO buttons at the FX Aux sends are up.
What effect does the MODE button have in SOLO and in PFL? Is the SOLO LED off? Is the number in the FX window SOLIDLY on and not flashing?

The flashing means the FX hasn't been activated yet. Dial up the number you want THEN push DOWN on the knob to activate and the flashing stops and the FX takes effect.

Do the following:

Set each of the FX mix knobs to 12 o'clock (halfway up to start)... I believe they are orange tops for each channel effects are desired for.

Next select the number of effect by rotating the selection knob. The display will flash.

Push DOWN on the selection knob to activate the selected effect number... the display will cease to flash. Note that you can mute the effects with a small button in the effect area and decimal point will come on showing effect, even though selected, is disabled. That small button can toggle the effects on and off.

Next, adjust the "FX to main knob" above the MAIN fader... set it to 12 o'clock to start with.
Note that there are two others that send the resultant same effect to stage monitors if used...

Now ADVANCE the FX (orange) fader to increase the input to the FX. You should start to hear the effects... SOME of the effects are subtle, so maybe choose a long delay one to get the hang of it... choose #3 for example...

The manual is NOT too clear how to use the effects and is confusing... they assume you have knowledge common to mixers... and new users don't.

I would recommend watching several YouTube videos about mixer setup... there are some good ones there !!! Most mixers have a lot in common and once you learn what is there, you can work most any of them... some of the new digital ones are a bit more confusing.

There are several clipping indicators on this board. Do you mean that the small vertical display to the left of the FX selection window is maxed out from top to bottom? I will assume that you have ALL the FX inout knobs CCW for all channels AND the FX slider all the way down. Also does the FX selection knob work to change the effect number? Does the rest of the board work? WILL the effects pass sound when you send it through the effects? You say no sound, but was that just to say with no sound sent to it it still is clipping, or that it will not pass sound?

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.

A high likelyhood of a power supply problem.

I had a similar thing on a GX110 and it was an electrolytic cap that filters for the 5 volt regulator on the DSP board.

As the DSP starts up, the load on the supply sucked it below the operating point and caused the DSP to keep reseting. The display did flash.

The unit will have to be opened and trpunbleshooting done to find and repair the problem.
