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.

When the phantom power is on, some channels decide to come and to. Particularly with the SM57 mic


Don't know what you are saying. Phantom power is only used for Condenser mics and a few DI boxes. Make sure you ONLY use TRS or XLR cables into ANY/ALL inputs when using Phantom power. Please describe what you mean by :some channels decide to come". ONLY change Phantom power when system is off as you will get loud noise often by switching phantom while live.

I have a Yamaha IM8. I had a condenser mic hooked into channel one with phantom power on. I had to leave the room for a while and when I came back, I noticed some rather severe popping in the audio. I turn...


There is really no way for a condenser mic to damage the board UNLESS you break the ground and get a static discharge into the input. That can happen with any microphone and has NOTHING to do with the phantom being on or off. As phantom power goes on and off slight bias at the input preamps can make amps non-linear causing the raspy sound you heard. The Phantom LED means NOTHING as it shows the state of the phantom switch by connecting a 12 volt source through a resistor to the LED... It shows NOTHING regarding the state of the 48 volt supply. Each input circuit has two 6.8Kohm resistors to the swinger of the phantom switch 2nd pole that either grounds those or connects them to a filtered 48 volt source. As long as you don't have a static buildup there is NO need to turn phantom power on or off while connecting a condenser microphone. At each input when using the XLR jacks are two per side 470pf capacitors for RF bypass. For the XLR's there is a 10Kohm between the signal lines and two series 10mfd/50 volt caps in series of each input to block the DC, when using phantom power, from reaching the preamp stage. These caps have to charge and discharge when changing the state of phantom power so you should AVOID having the main amps being driven while changing the state of any phantom power. Always have the fader(s) down and any monitors down to avoid a thump and also the non-linear raspy transition as the input caps charge/discharge. So fix the microphone... don't know what type you have, but DO check the cable (first) as ALL three conductors MUST be good for a condenser mic to work on phantom power. A ground leakage or noisy connection will cause your symptoms. Use a SHORT known good cable right at the board to test the mic. The 48 volts is applied through the two 6.8K resistors between both the signal lines to the shield of your XLR cable. The microphone picks off the 48 volts with a similar circuit.
Now let's cover a very important thing regarding system safety: ALL, and I do mean ALL interconnected equipment MUST be powered from the same source. Professionals run a power cord back to their mixer right alongside the snake. This is to avoid ground bounce damage due to bad building grounds or ground faults.

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.

I have a condenser mic, and it needed phantom power to work, so I bought the Ultra Di-100, but I don't know how to make my mic work with it.


Sorry, but the DI-100 can OPERATE on phantom power, not supply it. If you have a mixer that has phantom power then you have no need for the DI box. DI boxes are to convert unbalanced signals to balanced to send via XLR or TRS cables.

If you don't have a mixer that has built in Phantom power or a source of Phantom power, then you need a mic preamp that can supply the phantom power.

Here is an example device, but DO shop[ around as you should find some even less expensive. Make sure they have phantom power.

What is the switch for on the Phantom power unit at the end of my AKG C747?


Hi,the switch for the phantom power on the microphone is to activation of the mic.Without the phantom being activated, the mic will not work.

It can only be activated with a mixer console that has a phantom activation on it. After connecting the mic to the mixer,activate the phantompoweronthe mixer and switch on the phantom power on the mic,and problem solved.

Note: Mic will not work if no phantom activated on the mixer.

Sennheiser em100 g2 receiver passes major static to mixer


This is a well known problem with the EW100 series that is easily solved.
You will need to run this reciever into a line input via a mono(TS) jack to jack lead. this will bypass the phantom power.
Make sure that you set the AV OUT to +18 in the reciever menu to get optimum level.
Phantom power is only present in the microphone inputs XLR3.
Hope this helps.

Connecting phantom microphones without result


if you have a volt meter check the supply is working correctly
48v dc phantom power should be found between these pins on any xlr mic cable.

pin 1 and pin 2
also between pin1 and pin 3

make sure you have amps turned down before checking/switching 48v phantom power

as if all is up and running it can cause big noise in the speakers.

let me know how it goes
