Why is my Klipsch subwoofer humming?

Why is my Klipsch subwoofer humming? 

If you notice that your subwoofer is humming constantly, then it may require a bit more troubleshooting to find the cause. It is possible that the issue is being caused by a “ground loop”. Ground loops can often be resolved without spending any money on the problem.

How do I fix the hum on my amp? 

How to find and fix hum in 3 easy steps
  1. Turn the volume control up and down. Does the hum in your speakers go up and down with volume?
  2. Select different inputs. Does the hum go away?
  3. Disconnect all inputs. Remove the cables connecting the receiver, power amplifier, or device powering your speakers.

How do you fix a humming subwoofer? 

How to Fix Subwoofer Hum
  1. Change the polarity of the subwoofer’s connection. This is probably the most straightforward fix to try because all it involves is reversing the power plug’s orientation.
  2. Reverse other plugs.
  3. Separate the cables.
  4. Switch outlets.
  5. Use an audio isolation transformer.

What causes a powered subwoofer to hum? 

Why does my subwoofer make a humming noise? The voltage difference between a subwoofer electrical ground and the equipment ground can cause it to hum. This can happen because of the irregular current flow in your audio cable. Turning on the volume too high can also cause a hum.

Why is my Klipsch subwoofer humming? – Related Questions

Can RCA cables cause hum?

Hum noise is introduced from power cord, noise level increases when unbalanced RCA cable runs in parallel neighboring oval or flat type power cord. Using shielded round (twisted) power cord and increase distance between RCA and a power cord (and if possible, runs in perpendicular) alleviates hum noise.

What is a ground loop hum?

It’s most likely a cabling issue that is allowing noise from the building’s AC power lines into your equipment, called ground loop hum. This is caused by a difference in electrical potential at grounding points.

What causes a hum in speakers?

Though some noise is inherent in the audio signal (tape hiss, amp gain, etc.), speaker hum and hiss generally come from poor wiring, ground loops or other electromagnetic interferences (AC line hum; RF interference, and USB and PC noise). To rid of the noise, we must rid of the interference.

How do you reduce ground loop noise?

Power inter-connected equipment from different AC outlets is likely to create a ground loop: The ground will travel through the shielding of the signal cables. Anything that breaks the loop will remove the noise, and the easiest way to do it is to power everything through a single AC socket.

How do you make a hum eliminator?

How do you stop a 60 cycle hum?

Naturally, EQ set to any harmonic frequency of 60Hz will do a good job at cancelling out this type of noise, just make sure you use the narrowest Q possible so that your overall sound quality remains intact. You can also try using a high-pass filter set to either 60Hz or 120Hz to cancel out most of the hum.

Can capacitors cause hum?

Hum can also be caused by leaky filter or coupling capacitors. When this occurs, stray DC will get into the circuit and induce hum. This is more common with old capacitors but can occur to new too.

Where do you put the hum eliminator?

With a rack of amplifiers, we recommend putting an eight channel Hum Eliminator™ in front of your amps inputs so you do not have to solve ground loop problems during sound checks. A common path for ground loops is through a chassis into the rack and then into another chassis.

How do find a ground loop?

To test for ground loop:
  1. Set your volt meter to the most sensitive AC setting.
  2. Disconnect the camera you want to test.
  3. Place one contact on any exposed metal of the chassis.
  4. Place the other contact on the outside of the connector on the coax from the camera.
  5. Any value above 0 indicates a ground loop.

Does the Morley Hum Eliminator work?

How does the Ebtech hum eliminator work?

How does a ground loop noise isolator work?

So, how does a ground loop isolator correct for the noise? A ground loop noise isolator has a separate isolation transformer on each channel. The transformer magnetically transfers the audio, but will not transfer electricity. As a result, the DC noise caused by the ground loop is eliminated.

How do I use my Morley Hum Eliminator?

Simply place a channel of the Hum Eliminator on the cable connections between the two offending pieces of equipment. The Hum Eliminator will not affect the quality of the audio, it will improve it. It uses 1/4″ smart jacks that accept any combination of unbalanced (TS) or unbalanced (TRS) plugs.
