Mixer Switch on and after a short period theres a noise that sound like a machinegun and a Hiss sound through the speakers


I assume that the power-amp is good.
This noise, of course due to defective parts inside.
But, which section is it? Chances are:
  • Amplifier circuit in the Main-Outputs. If the MAIN MIX in the minimum position and still noisy, then the damage in that section.
  • At one or several channels. Let's test.
    Set to minimum volume for all channels and MAIN MIX. EQ=flat. FX=minimum. TRIM at half (let's try at 12 o'clock).
    Raise the MAIN MIX, let's say at 15.
    Gently, raise channel 1 volume to maximum, listen, if there is no noise, channel 1 is safe. Lower the volume to the minimum again. Move to another channel in the same way.
    If found noise, that is where the problem is.
Actually, many more detailed steps for testing, but the description is too long. This above is a simple way.
Circuit power supply should also be checked, whether all normal voltage.

Woofer rattles at low volume...when i turn it up it sounds pretty good...still has bass and highs


May be a couple of things; The first is a resonance in the cabinet, which may not be noticeable at high volumes. If the speaker cabinet was ever dropped,or got cracked from dropping , dry weather,or whatever, there may be certain frequencies that make the cabinet rattle. Try holding the cabinet when it rattles and look for anything loose,from a side wall to a loose foot, or the speaker itself. Tighten up loose items and seal any gaps or cracks On the cabinet.
The other problem could be a partially blown speaker. Test by lightly pushing in on the outsides of the speaker to see if it moves in and out freely. If there is a scratching sound, or it drags slightly , it might be blown. Also,the dust cap or another part of the speaker may be loose. Check that, and reseal if loose. Replace or have reconed if blown.

Speaker humms only. what causes that?


Incorrect connections or volume settings.

• In powering up, mixer first then amp

• In turning off , amp first then mixer


If hum still persist, without the mixer connected

then speaker amp may need servicing.

Played samson 412 aura speakers for about 6 hours today with the volume at 1/4 of the way turned up.. the speakers became very hot and turned off by them selves.. I have them mounted on stands in a corner...


The volume setting on the speakers has LITTLE to do with how hard you are driving them. Your source might be extra hot and overdriving them. Read the specs on the speakers and use a sound meter to check your level. The speakers, being only 12 inch, should fill a room 20 foot by 20 foot to about 95 to 100 Db which you are only allowed 2 hours in MAX to prevent hearing loss. At 6 hours you should keep it down to 85 Db SPL. I know several deaf musicians that were exposed to high sound levels in rock bands... a deaf musician is kind of washed up.

Hello, I own a hotrod deluxe. I take great care for it and never move it. Normally on the clean channel, the volume is regulated by the volume and the master. Today the amp sounded only half as loud as...


Do you turn on standby every time and wait for the tubes to heat up first? If you don't, it can severely damage the tubes.
But a common cause of this could be just old tubes. Like any other piece of technology, tubes get old. If you like to play your amp LOUD then they wear out a lot quicker. You have to replace tubes every now and then. Because I'm not there to check out your amp, I can't give you an exact answer but it sounds like that's the problem. This isn't always a bad thing. You can make the sound of your amp exponentially better with nicer, new tubes. Your amp has 12AX7 tubes. Very common tubes to use actually. I'm not sure what kind of music you play, I'm assuming mostly rock and blues. But here is a list of tubes and reviews on them.

This is how to replace a tube:

A note he doesn't make in the video is to dust out your amp. I use the compressed dust spray for the inside of computers.
So overall, stop turning up your amp to 11, make sure it's well ventilated and dust it out from time to time. Hope this helped.

Check only one active speaker at the mixer output and report the results.
Connect only one of the audio inputs from the power amp at the mixer output (and the passive speakers at the output) and report the results.
Sometimes (in parallel connections) there are interferences from the volume controls.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Wires to main speaker are, Yellow & Blue witch one is the positive ?. Also I am getting distortion from the clean channel even at low volume, the speaker is Peavey 1230 model 8 ohms.


Yellow should be the positive. Try plugging in and reversing. The louder of the two is the one in phase and the correct wiring. If the speaker is pushing out when playing , it is in phase and correct also.
The distortion problem could be a speaker going out. It may not be totally blown, but may be verging.
Holding your hand out as wide as you can push against the speaker lightly. If there is a rubbing or scratching sound, the speaker could be damaged.If it moves freely, and there is no scratching its okay.
Another possibility is the clean channel may have a channel volume set to high. Make sure the clean channel volume is set lower than the master volume otherwise you can get distortion on that channel too.
Good Luck.

HOW DO YOU TURN DOWN THE HISSING NOISE


You can cut the treble gain some BUT most importantly is to send adequate signal to this speaker so volume level does not have to be set high when sending LINE LEVEL signals to it. Hissing noise is a product of the statistical noise that occurs in electronics. Running any device at high gain invariably brings up the hiss level. Managing thee signal levels is the responsibility of the sound engineer.

ALSO feed ALL interconnected equipment from the same receptacle or power source, even if it means running a power cable to a mixer alongside the snake. ALWAYS USE BALANCED audio cables whenever possible.

Scratchy volume potentiometer


Try cleaning your volume potentiomenter with contact cleaner (they come in spray can's), the scratchy sound is audible when you turn your volume control on, the contacts inside your potentiometer accumulated dust or some other particles.

Might want to try turning the volume control back and forth. IF you hear scratching, there could be some dirty contacts that are causing this problem. Turning the volume control back and forth sometimes helps "clean" it.
