SOURCE: My Audio-Technica AT4033CL mic worked

The most common problem at these cases is a loose of the phantom power. Take a closer look at all the connections and check that the phantom power supply voltage is enabled at the mixer. If it's possible check with a multimeter that you have 48V DC at the 2 - e pins of the XLR connector.

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.

I have an audio technica ath-anc7b noise canceling headphone. There is a crackling sound when I tap lightly on the left hand side of the earphone. There may be something loose. How can I open the cas


I was researching a similar answer and discovered that the left side ear piece actually is actually held together with 3 torx screws that are visible upon removing the ear pad and the padding surrounding the driver. I haven't had a chance to attempt a fix yet but remove those screws and see if you can open the ear piece.

Sennheiser HD 205 crackle when listening to music


If the crackling occurs only when opening windows or another program, the crackling is not due to the headphones but to a lack of CPU resources in your computer settings.
If you are in Windows 7,
  1. click the Start button 4f6cbd09-148c-4dd8-b1f2-48f232a2fd33_818.jpg, and then click Control Panel. In the search box, type Performance Information and Tools, and then, in the list of results, click Performance Information and Tools.
  2. Click Adjust visual effects. 18abb370-ac1e-4b6b-b663-e028a75bf05b_48.jpg If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
  3. Click the Visual Effects tab, click Adjust for best performance, and then click OK.

Left side is quieter than right side and when pushed on makes crackling noises and sound gets louder


most likely cable is very loosely contacting the jack or earpad. Will need to be taken apart and soldered.

My reciever volume cuts in and out and crackles when adjusting


You can CLEAN / LUBRICATEthe volume control know with a CONTACT/CONTROL cleaner, I use a product from Radio Shack, this works wonders on drum type electo mechanical devices which are basically volume control knobs, easy to do, just remove the round knob and spray into the openings with the small tube attached, and rotate in both directions, be sure to unplug the unit first, on a few occasions it is best to remove the front panel to acheive better coverage to the rheostat type volume body, anyway it always cures the crackling and distorting sound, I would give this a try before replacing the part.

Pioneer VSX-36TX popping and crackling during warm-up period


I have the exact same amplifier with what sounds like the exact same problem. I opened up the amplifier, and while it was powered on started tapping around until I heard the popping and crackling suddenly increase. I was using a piece of wood and the plastic part of a screw driver for this. The popping and crackling suddenly burst out onto all channels when I was tapping on the DSP board (encased in a metal enclosure to the very right of the amplifier).

I took off the metal enclosure (with the receiver turned off, of course :), and with the receiver on, and started tapping around the DSP board, and I found that the biggest crackling effect was achieved when I tapped on the Cirrus Logic CS493292-CL chip which does all the decoding and switching.

I detached and took out the DSP board and looked at it very carefully but of course couldn't find any bad connections. I tried resoldering all the feet of the Cirrus Logic chip and many many components all around to no avail.

Finally I tried applying pressure to the chip while the popping was going on, and it stopped. Further investigation revealed that bending the board around the chip produced the same effect.

For the life of me I couldn't figure out why bending the board eliminates the problem, but my solution was to put a piece of eraser wrapped in masking tape and taped to the Cirrus Logic chip, and two other pieces on the back of the board in such a way that when the metal enclosure was replaced onto the board, it put gentle but firm pressure onto the Cirrus Logic chip and at the same time bent the DSP board slightly.

It's been a few days without popping, clicking or static, but time will tell. Good luck!
