First thing is to run a known signal from a simple device like a small CD player to verify the problem.

If these are driven from a mixer, the EQ could be set to kill the highs.

Assuming it isn, something simple like an EQ setting, probably the units will have to be serviced. I know you would already have checked the EQ on the back of these things as a first step.

Remember to ALWAYS power these from the same source as the devices connected to them to avoid ground loops and damage.

Supersonic feedback can fry these. Oscillations higher pitch than you can hear can put too much power into the tweeters of these.

One speaker stopped playing bass

Sound like either the crossover or the driver has blown or, if you're lucky there is a loose connection internally if you have only checked external connections.

When I connect my cables from the TRS outputs to my direct-field monitors, the latter seem to be unbalanced: one monitor plays more higher frequencies than the other

Plug in one a at time using the same input. Take the left speaker and the left input wire. Plug the wire from the mixer into the one speaker if it sounds ok then unplug the speaker and replace it with the right speaker. If it sounds ok replace the wire with the right wire. This will tell you that each speaker is working and each cable is working. If you switch speakers and they sound different then the possibility of a blown high end driver in one. If they sound ok each by it self but the high end suffers when they are both hooked up then the possibility of the speakers might be. Not sure what the sub has to do with the whold setup. Any further questions call me at the store.

My 200hd head is not putting out the full 200 watts i have a behringer 8x10 cab and before this head used to power this cab fine now even with the volume cranked you cant even feel the bass i have...

I am not sure how you are measuring the power output to verify it is less than 200 watts. With a true RMS voltmeter you should see 28.28 volts RMS across a net speaker load of 4 ohms. If you use only one 8 ohm speaker, you will get 120 watts. If you are getting the 28 volts there is nothing wrong with the amp. You MAY have blown the speakers OR not generating much bass due to processing in an EQ. I assume you are using at least 15 inch speakers if you want to feel bass. Look up your speakers specs... you will need speakers capable of 32 Hz to feel much. With this amp your speakers should have aa total rating not less than 400 to 600 peak watts or around 300 watts RMS continuous power rating. Using a lot of high end EQ will keep the amp busy at the high end and reduce the power available at the bass end.

I have a two way peavey p115 speaker system and audio has stopped coming out of the high frequency driver . I tested the high frequency driver with a multi meter and it is fines.I also have a working...

Testing the driver with an ohmmeter is incomplete test. Sometimes the magnets break off the drivers rendering no sound. Sometimes the voice coil shorts and if you don't interpret the ohmmeter readings correctly you can overlook a faulty driver. Remove the horn and look for damage such as lost magnet from the back. Also the peavey cabs have a protection circuit so if you did not try another speaker to the same wores going to the driver, it may be the Polyfuse on the protection circuit or other components.

The low end gives a lot of feedback if turned too high. Any reasons why?

Probably the soundboard is resonating. If you out your hand on it or the strings it will probably stop resonating if it was just on the verge of feeding back. This is the main reason why solid body guitars were invented in the first place.

There are ways to minimise this, however. Speaker placement, eg have the speakers beside you and facing away to the audience. Stand further from the speakers. Use an eq pedal and lower the gain around the resoant frequency. Use a chorus/flanger pedal. This can help smear the frequencies and reduce feedback. If you google "reduce acoustic guitar feedback" you should find other ways. Also, if there is a way to increase the gain of the pickup by placement, do that.

Clavia Nord Stage EX88 dir. in active monitor damage the speakers (tweeter) ? Happened twice with active monitors: Peavey Impulse P1020 and Behringer B-300 Peter ;-)

It is VERY easy to send to high a level to speakers.

A few important things:

ALL interconnected equipment MUST be powered from a single point. This avoids ground loops that can set up feedback. Powering monitorss at one end of a room from a receptacle and the synth at the other end of the room is inviting trouble.

REMEMBER that audio sent to the speakers that is causing the damage MAY be well above one's hearing range!

Use BALANCED audio lines where possible. CHECK that in's and out's are compatible, for instance both BALANCED TRS.

Use PROPER cables for interconnecting. Using plain stereo TRS cables for interconnecting TRS balanced lines is a NO-NO... they are cheaper but invite trouble.

If in close proximity to radio transmitters, interference can be a problem due to rectification of the radio signals that can create frequencies beyond the hearing range that can damage speakers.

The starting point is a post mortem on a failed speaker to look for damage.

The Behringer definitely requires a TRS or XLR input. I searched for a user manual online for the Nord but was unable to find one to verify they have a balanced output to run to the monitors.

There is a possibility that a filter in the NORD is NOT working, allowing digitizing noise to be presented on the output audio causing overloading of the tweeter speakers. The best way to check that is with an oscilloscope if you have access to one.

I would turn down the high eq on any active speaker to reduce the signal to the tweeter as an interim step.

Spider III makes a high pitch sound when I plug my cable into the input slot. It won't stop and it keeps echoing.

If your guitar is not connected and the cable alone causes the oscillation, I would certainly question the QUALITY of that cable.

Poorly sheilded cables can pick up ground loops.

If you short the contacts of the cable at the guitar end and that stops the oscillation, I would try a higher quality instrument cable. MAKE SURE the cable you are using is an INSTRUMENT cable and not a SPEAKER cable which I can guarantee would cause the problem.

The Line 6 amps are NOT noted for reliability so I would NOT let that oscillating conditipon persist for any length of time.

Do NOT use excessive gain at the front end,,, use higher master volume and less front end gain if you are having ground loops.
