Question about Electro-Harmonix EH-TM Microphone

1 Answer

A buzzing sound

So I've go the electro harmnoix tube mic, it's running in to the new Apogee Duet, phantom power, and I'm running through Garageband's newest version on my Mac G4... 
but.. there's a really loud buzzing sound audible whenever the mic is turned on. At first i thought it was my computer's fan, but it's not- moved the mic away. Is it possible that I just need a better XLR cable running from the output of the mic's power source into the Apogee duet?
any thoughts?! I'm learning...this is somewhat new to me- trying to get started recording a home album. Looking forward to suggestions...thanks!

The cables always a usual suspect, but if you are using a tube mic, wich have their own power supply, you don't use phantom power and it can damage the mics power supply, so take phantom power off that mic and if that doesn't cure the buzz then I would change the cable next.

I have recently bought an AKG Perception 120 microphone and plan on recording through GarageBand on my Macbook Pro, but no sound is coming through. please help!


You say you have a XLR to USB adapter....so the version of the 120 you have is the regular XLR version, right? Well if it is, it needs what's called "phantom power" to work. It looks like they have a straight USB version of this mic, and that's what you should have gotten if you didn't want to use anything else. If you still want to use this mic as is, I would recommend a Focusrite Scarlett 2i2. I have one and it's great. I do have a pc though and I'm not sure about Mac. But it's a usb powered preamp that gives you two mic pre's along with headphone amp, and a volume control for your speakers and has phantom power built in. Great unit and around $120. NFI.

C1 not working


Sounds like your Phantom power supply may be defective. To be safe, 1st try moving AC plug for Phantom supply to another outlet as sometimes "sharing grounds" can be a problem. If this doesn't help, try using another phantom power source ...many PA mixers have built-in phantom power. If the buzz disappears with a new one, it will be a filtering issue (capacitors) with the old phantom supply.

C1000s hum/buzz on phantom power


possibly the microphone needs more power than your sound card can supply although I cannot imagine as the duet is a good piece of equipment.
Is the duet USB bus powered?
Have you tried another cable? Possibly one wire is defective which means that phantom power will superpose the audio signal. In this case you might hear a hum. By the way this results in 6dB of signal loss. This is why XLR plugs have 3 wires. If connected with a 1/4" jack it has to be a stereo plug (tip, ring, sleeve)

I have set-up M-Audio microphone recently but I can't seem to figure out HOW to begin using it. I've tried every drop down and clicked every recording button while I was using the software. . . is there...


Without knowing your setup or the mic model, my guess is that you need to run a phantom power supply to the mic to get it to function. This is done either by using an outboard analog mixing console or mic preamp with a phantom power switch, or using an inline phantom power supply. The microphone plugs into the mixer or mic pre with the phantom turned on, and then into your DAW system.
The phantom power works with condensor microphones like the one you have. It sends a 48v signal to the microphone element, which in turn energizes the element and makes it function. Dynamic mics, like a Shure SM 58 for example, do not need the phantom power and will even ignore it if run on a phantom powered channel. condensor mics however must have it to function, otherwise there will not be any sound. Hope this helps. Good Luck.

That microphone is a condenser type of mic. It needs to have phantom power (48V) in order to operate. Phantom power is available on most, if not all, audio mixing consoles. Hope this helps.

How to use a condenser mic on a mac/in garageband?


Hi,

If you are sure that the microphone and the cable is OK, it could be that you're phantompower is to low.
Normally you need 48 Volt, you can check that with voltage meter between pin1-2 and 1-3 from the XLR.

regards,
Gerard

Sound Problem


What are you running this mic into ?, an interface mic pre ?, a soundcard ? A console/ mixer ?
Since this is a tube mic it should have its own power source and I am assuming you plug that in when using it ? Don't use phantom power on this mic, even though it's a condenser mic, since it's a tube mic wich have their own power supply you don't need phantom power on them and in fact it may damage its power supply.
