Question about Dual CAD VX2 Valve Multi-Pattern Condenser Microphone Microphone

Open Question

Ive just bought a t.Bone sct800 valve mic. It is producing regular click/pop noises every 13seconds. There is no abnormal background hiss, and no background crackling noises. The only thing i can think of is capacitor problems. Ive tried plugging the power supply into different sockets, and moved both the power supply and mic into a different room to the computer, both with no change to the click noises.

How can I reduce white noise / hissing I'm getting over the mic on a Behringer Xenyx 1204 USB setup?

Hi, you didn't say if the mic actually passes sound? The C-1 is a condenser Mic & needs phantom power - switch on the rear of your mixer. If that's no help, what happens if you disconnect the mic, then turn the levels back up? Still hissing or gone? If it's gone then it's the Mic - must use a 3 wire cable, preferably XLR so it gets the phantom power. If the hiss is still there without the Mic then sounds like the mixer is faulty - try some of the other channels..... How loau is the hiss - just in the background or as load as a vocal "one, two" test? A few things to check anyway...... Good Luck!

How do I fix........Getting rid of background noise coming from my JVC KWV21BT?

You have described a grounding issue. This "hiss" is due to one or more speakers &/or the radio itself not grounded properly which is producing the "hiss". I would take it back to the installer and have him correct this problem. They have a responsibility to make sure it's working 100%.

I got a rode classic II with avalon m5 mic pre. So when i crank up my mic pre to 60 n i can start listening some hissing from my monitor...or is it normal for a valve mic coz when after recorded with this...

The hiss is caused by your monitor system level and your preamp gain being so high. At high gain settings, a preamp is going to get noisy, and tube mics have a higher noise level to begin with.

If you can't hear it on your recordings, then it's not a problem.

Hi I have a CAD VX2 that has intermitant noises showing up. they are quiet, but noticable. I have tested it without the mic attached to the power supply and i get NO noises.... the noises only show up when...

Condenser mics will not generate ANY audio, noise or otherwise without a power supply... so that test may be moot.

You have not described the noise so I will try to cover possibilities:

1. ALL electronics generate a random thermal noise which is a limitation of physics. This noise is a random "hiss" for lack of a better description. The level should be many Db less than normal program.

2. Wind noise due to air flow or singers popping... you can sometimes shield this or use pop filters for singers.

3. Crackly noises are often caused by bad cables or connectors... I recently found 6 of my mic cables were MISWIRED so they basically were unshielded/unbalanced. Check that your cables have the shield on pin #1 and the other pins connected respectively at both ends.

PLEASE google the connections for XLR cables and pin arrangement as they are weird layout.

Some cable is of poor quality and generates more noise due to poor shielding and inadequate twisting of the signal pair.

Ive had this mic for a long time, and all of a sudden theres a background noise? anyone know how to get rid of it?

Check your cables, try different cables. If used for singing, be sure to use a pop filter/windscreen, this helps with moisture from getting on the capsule, which can fry the capsule. Also, if it was ever dropped. Obviously, this mic needs phatom power to operate, so make sure that supply is good.

Microphone sound quality

sounds like you are using the wrong fx... acid studio comes with some professional plug ins. use those instead. they have one that allows you to take background air, and noise out of your recording it's call background gate. none if this may make any sense to you so i have pictures.


after you click your green FX icon next to your track don't use the features below. go to where the read arrow is pointing. click that green fx icon instead.


click the all folder on the left side. on the right side will appear a list of plug in's/special effects (red arrow is pointing to the list). their is one called a noise gate use that to remove background sounds and air.

they have other features like chorus and reverb... these plug in's do great. i hope this helps.

you can add whatever effects you like on one track and save the effects as a name. that way you can add it to every track and don't have to go through the whole process of selecting the same fx for each track. i really hope this helps i'm not very good with explaining things. ha ha ha.

This is a wonderful microphone that I used for years without any problems. Then it developed a background noise (a hiss, or buzz, or sound like a bad ground; it's been too long and I don't remember the specific sound now). I checked the integrity of the ground and other wires in the cable and didn't find any problems so I replaced the old cable with a new cable, but I still had the noise.

I use the microphone with the microphone head separated from the microphone body, so I have a cable that runs from the head to the body and a separate cable that runs from the body to my inputs. I don't have either an electrical or logical explanation for why the following solution got rid of my noise, but it worked for me.

On the cable that connects the head to the body, simply take an insulated wire, strip both ends and with electrical tape, tape one bare end to the metal plug shell on one end of the cable and then do the same with the the metal plug shell on the other end of the cable. You can add some tape wraps along the length of the cable so it doesn't look so funky and is a little less cumbersome. I didn't do anything to the cable that runs from the body to the inputs. This got rid of the noise for me. REALLY. THIS IS NOT A JOKE. I DON'T KNOW WHY, BUT IT WORKED FOR ME. Maybe it will also work for you. It's certainly easy enough to try. Good luck. Bob

AKG C535 microphones pop and hiss

if they are "condenser" mic's, the condensor module, as in the case of capacitor, failed as time goes. <condensor = capacitor>. Might be a good idea to check other capacitors inside.
