I am trying to connect a Behringer 802 Mixer to a Pyle PHA40 headphone amplifier in order to use my two sets of headsets with microphone attachments in order to broadcast local sports. The trouble I am having is that every time I connect all of the equipment after about 2-3 minutes the headphones start to produce a terrible humming noise. I have tried everything from turning the power plugs 180 degrees, to plugging both the amp and mixer into the same and different outlets respectively, as well as turning down the microphone volume or the headset volume thinking I was getting some sort of feedback. I have never had any humming just using the mixer and a headphone spliter, however I do not want to use this option as my broadcast partner and I want to be able to adjust our headphone volumes to fit our individual liking.

What does the receiver go into ?
a pre amp mixer ?
What are the volume levels set at on the mixer for the receiver input ?
Also check if the pre amp goes into another amplifier that the volume setting on the final amplifier device if used have not been turned down.
Bet someone has fiddled with these settings of volumes !

1. Yes, you need the PS400 with the B-1. Alternatively, you can connect the mic to a mixer with built-in phantom power.
2. The PS400 shouldn't go directly to to the TA2020 because the power supply is providing a mic-level signal and the amp is looking for a line-level signal. Either add a mic preamp after the power supply, or if a mixer is used, that output can be fed to the amp.
3. Cabling will depend on what you ultimately choose to do. But, you'll at least need a mic cable to go from the B-1 to the power supply or a mixer.

the mixer connects to the pc via usb or analogue i/p's
the mixer does not connect to the pc speaker
this has to be done with the software you're running on your computer
the easiest way is..plug the headphone o/p into any amplifier line i/p
( amp and speakers or powered monitors ) and forget about the pc speaker ..they're sh!te period ..or you can plug the headphone
o/p into the mixer then the mixer into an amp but this is more complicated and you will need to read up on it
but do yourself a favour and get some small multimedia speakers
similar to these for starters http://www.ebay.co.uk/itm/GENIUS-BLACK-MULTIMEDIA-STEREO-SPEAKERS-SYSTEM-for-LAPTOP-DESKTOP-PC-COMPUTER-UK-/250929417549?pt=UK_Computing_Speakers&hash=item3a6c8f0d4d

IF your Laptop has a stereo LINE 1/8" INPUT jack, you can take the Stereo ( Left & Right ) LINE outputs on your mixer and feed into this jack on your PC. You will need a 1/4" dual plug for the mixer end to a single 1/8" stereo plug on the PC end. I suspect the problem you are having is either related to your PC only have a MIC input jack or you have something set wrong in your PC's sound config. file. More information is needed to properly solve the problem.

Sounds like it may have failed. Yes, it is likely that it needs to be returned. Another option is to unplug all inputs and outputs. Plug in ONE device into the board, and use the headphone jack on the board. Does it sound the same? Just basic troubleshooting may help.

The unit has a built in mixer as well as individual outputs. You would need an amplifier/speaker that could receive from teh mixed output jack of this. Use BALANCED TRS cable.

This happens when you have lose earth connection from your main source power supply. Check the earth connections (grounding) which should be available in the mixer, i.e some power cords don;t have earth wire, so change this if you think yours don't have it. Also check the grounding of the other items attached to your mixer, basically grounding is very important to reduce the static shorts. Try changing the power supply source, change to other outlet and check if it is OK.

Hello Sir, Hi, the amplifier best suited for it would be a Behringer also, the EP2500 would be a match, and the eurolive B815neo speakers, but this cost a lot, any amplifier and a corresponding speaker will do. for your electric guitars or acoustics the GTX30. If you will use your 15" speakers, match it with a right amplifier, you did not mention its watts rating, If your speakers are 250 watts, then buy an amplifier slightly higher that 250 watt,

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.

I can't tell from the add but hopefully it comes with adapters for both plugs that will work on your mixer. It does have the one for the headphones but the one for the mic is not clear, they are not interchangeable.

You would obviously plug the headphones into the headphone jack. The knob labeled "Phones/Control Room" will control the volume without changing what's being broadcast. What you hear in you phones is exactly what you are broadcasting.

The microphone needs to go into either mono channel 1 or 2. The adapter for it needs to be a mono Tip/Sleeve adapter as the more common stereo Tip/Ring/Sleeve adapter may cause some problems. You can tell the difference by looking at how many sections are on the plug divided by a little black line. Two sections is mono, three is stereo.

Adjust you microphone level by setting the volume knob, the one on the very bottom, to the 12 o'clock position. Then turn the gain knob, the smaller plastic one on the very top, until the desired volume is reached. If you experience any clipping or distortion turn the gain knob down until it goes away. These are general settings, you may want to experiment until you get the best level without noise.
