AT 4060 valve microphone

I have an AT4060 Valve mic, that is making low level popping and fizzing noises.

If I disconnect it from it's power supply, the noise disappears, so it's not the PSU.

About 2 months ago I did notice that there seem to be a bit too much distortion creeping in so I figured it must be the 7 year old valve on it's way out. I very carefully replaced it wearing gloves etc. and it seemed to fix the distortion problem.

Although I'm no techie, the recent popping and fizzing noises remind me of times when the capacitors were on their way out in other equipment.

Any help, advice or where I could get some would be much appreciated.
Many thanks,

Re: AT 4060 valve microphone

Check out this gearslutz thread. It's pretty informative & the person found the solution to be to install a new tube/use a dehumidifier.

I hear a white noise when I connect microphone with mixer (Behringer DX2000)

You posted this in questions about the Shure PG42 mic. That mic comes in two versions. There's the USB version which connects direct to a PC. Then there's the standard version which is used with a mixer. I presume you have the standard version as the Behringer doesn't have inputs for USB mics.

The standard version is a condenser mic. It needs power. The power is supplied by the mixer. It is known as phantom power because it travels up the mic cable from the mixer to the mic.

  • Make sure your mixer has phantom power switched on.
  • Use the correct mic cable: Either a 3 pin XLR to 3 pin XLR, or a 3 pin XLR to 3-pole jack (TRS). The leadis a balanced mic cable

  • Check the setting on the mic for attenuation. 0dB is no reduction in signal level. 20dB is a large reduction

  • Look at the Behringer's settings. Make sure you know what each control does and how it affects the sound. Pay particular attention to the effects send and return (FX SND RTN)
Most times there's an issue with no sound from a mic, it's usually down to a poor quality or broken cable; or no power; or the settings on the mixer.

I have an rode nt1-a microphone, roland quad capture interface, but when im gonna record or put the input level i hear wind, i turn down the input volume all the way down, i still see the input signal

The Rode NT1A mic is a condenser mic and therefore it REQUIRES that "phantom" power be supplied by the mixer or amplifier. You will get only electronic "noise" if the mic is not receiving this power. Look up Phantom power to understand it. Essentially DC power is sent up the mic cable between the signal lines and the shield of the cable and is used by the electronics in the mic to amplify the signal from the condenser element.

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.

Sometimes my AKG Perception 420 won't record properly, when played back it sounds like white noise with the faintest sound of what i'm trying to record in the background

All microphones have a signal to noise ratio. Basically defined as the level of desired sound to background noise (unwanted sound). Microphone phones also have self noise which should be considered when choosing a mic. There will be noise in every mic, some more audible than others. Condenser microphones require phantom power (48V). This can be supplied by mic prea
mps, mixers, and similar equipment. *Note that phantom power (mic pre amps) must be on or engaged, this can be specific to different types of equipment.
Troubleshooting:Has your microphone been dropped or exposed to moisture? Internal damage to your microphone will be hard to assess but this could possibly be the issue. Inspect the microphone cable, check for damages. Try using a another microphone cable-- preferably a new one. Next to check would be your mic's power supply. Make sure all connections are made properly (mic to cable to power supply). If you are using a mixer or pre amp with multiple inputs, test the mic on each input. (You should test by making recordings and comparing with each change to isolate possible causes). Also test the mixer or pre amp by slowly sweeping the input gain feature while recording an audible source such as singing into the microphone. Typically next in the audio recording chain would be your DAW (digital audio workstation) or computer, but problems with noise most likely precede this.
I could possibly provide more useful information if I know your exact setup.
Provided that you have your equipment setup properly, the microphone or mixer/preamp could possibly be damaged/malfunctioning. I suggest taking your equipment to a trusted repair shop, or if still under warranty, returning to the manufacturer for repairs or replacement.
Hope this helps

I have a mxl 990 microphone and its hooked up to a Pro tools LE 8 Mbox Mini . when im recording on protools or any other software with this mic, i hear a static/popping sound and it records the popping...

Try increasing the latency. Depending on your computer, it may not be able to handle low latency levels. Latency is a measure of the delay between the time you make a sound and the time the computer records that sound. With the Mbox mini, the unit for latency is the number of samples the driver collects before sending them to an application as input. Lower latency can make recording easier and more accurate, but not all computer systems can operate at the lowest latencies without introducing noise. Open the Mbox mini dialog and select the latency tab. experiment with higher latency levels and see if it goes away. somervta_0.jpgThis is what the dialogue might look like. another solution would be to try a different DAW. I had the same problem with my Fast Track Pro in ProToolsand it worked fin on Reaper, Garageband and Logic.

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 too quiet

That's probably not going to work.
Mic level is extremely low compared with line level.
Your sound card is expecting a line level input.
It's simply not made to plug a microphone into (you must be using an adapter or two just to make the connection)
Look for a USB Audio Interface with XLR or 1/4" microphone inputs - these interfaces are pretty generic these days and easy to use ... just plug into your computer via USB and then plug the mic into the interface ... which has a volume control on it ...
I use a Tapco Link.USB ... and like it

SAMSON CO1U recordings sound like they're underwater on my MAC

The behavior you describe suggests that the mic is not getting power. Since it is a condenser mic, it requires what is usually called "phantom power". This should be provided thru the USB port. Check to be sure that the USB port is supplying that power. Check with another port for example. If that fails, you may have a defective mic.

Keep us posted.
