20 Most Recent Behringer Xenyx X2442USB / Harbinger APS15 PA Package Questions & Answers

Likely the power amp has shorted to one rail... DO NOT attempt to use it as it could be sending high current through the speaker causing damage. Age of the unit doesn't have much to do with it. Take it in for repair. Unless you are electronically adept and can get a schematic this is not DIY.

First thing to check is look in the Windows Control Panel at the the "Sounds and Devices" and verify that the 2442USB IS the device for both input and output instead of the usual PC audio devices. You should see a pulldown list including both for those... If not, your SW driver is NOT loaded properly.

If it's a problem with the drivers, when you go to the manufacturer's website to download them, merely type in the exact product you have and the website should give you the specific driver/s for your product. If you go to the icon for XP's volume and recording tools, make sure that you've engaged the mic to function and that it functions at a sufficient level. You can find those tools under Control Panel, and then select SOUND, and then select RECORDING to adjust the mic functions.

Yeah, you can plug right in. Like you said, just do 1/8 inch out of the head phone jack to RCA into the AP15. All good!

Hi Mark, I mailed Behringer and they sent me details of how to do it. If you mail me at [email protected] I'll forward it on to you. It looks really complicated to get a stereo signal through but I just use mono signal and its simple and works really well

Proper level setting of the mixer is important. HOWEVER if the clipping is occuring at the speakers the only possible problem MIGHT be that you have a supersonic feedback that is saturating the speakers above your hearing range, Be sure you don't boost the highs too much with the EQ as this can cause the feedback that you can't hear. Also make sure that you power the speakers from the SAME receptacle as the mixer, even if it means running an extension cord to bring power to the mixer. This is to avoid a low frequency hum and common mode distortion/damage. A low frequency hum could cause the clipping.
It would be a good idea to get a sound meter to check the sound level. You should be able to reach 85 Db from this system without clipping. If you need more than that, you MAY need more speakers if the band instruments are too loud. Also if the band has amps that get into the vocal microphones that adds to the clipping level... make sure the mics don't "hear" the band instruments. Make sure your speakers are toward the audience from the mics to avoid the supersonic feedback problem. If the vocalists can't hear themselves with that configuration you need to set up seperate stage monitors.

There are some pretty good videos on YouTube about proper mixer level setup.

TRY E-BAY.

Additional, if problem is isolalted to the speaker and it acts the same with a CD player, the speaker should be serviced. It may be the crossover network, or the horn driver has failed or a simple thing like a wire coming loose.
If the problem is in the laptop, check the settings for audio in the control panel as there are settings that could have got clobbered. Video games are notorious for clobbering settings.

It is possible the tweeter prtion of the APS15 has failed. Try a different audio source such as a CD player to verify which part is bad, the speaker or laptop.

First, make sure ALL interconnected equipment is POWERED from the same receptacle.

Second, if the sound is routed through your computer via USB, make sure ALL background programs like wireless internet connection, anti-virus, anti-spyware, popup blockers are DISABLED.

These system hogging programs can interrupt the flow of the sound data causing static like noise.

Also use balanced lines for ALL audio interconnects... eithe XLR or TRS cables.

Probable power supply issue. Check the + - rails.

You will need an oscilloscope and a good grounding in electronic servicing to attempt a repair. But, check the signal routing. Refer to the user manual.
