Question about Sennheiser EM100G2 RACK MOUNT G2 RECEIVER (B) EM100G2B Microphone

Sennheiser em100 g2 receiver passes major static to mixer

When the receiver is plugged into a mixer with its phantom power turned on, this unit produces major static on the channel; as soon as the phantom power is turned off, the signal is clear and the receiver works fine. All of my other receivers work fine with phantom power on (the phantom power is needed for stage mics and the mixer doesn't afford individual channel switches; either the phantom power is on for all channels or off). Is there an easy "fix" for this receiver that can't seem to handle the phantom power?

    Thanks, Pokethebear, for the suggestion. After much trial and error, I finally figured out the TS cable fix. I actually have three receivers with the problem. The TS cable fixed two of them; the third wouldn't even work with this fix, yet as soon as I turned off phantom power, that receiver worked fine... "Quick fix" aside, I'm trying to find out what "broke" or "fried" with these three receivers to make them unusable with phantom power (my other units work fine with it) so that I can make repairs and continue to use my XLR snakes without modifications.

    Hi. Thanks for this response. It keeps coming back every now and then, so I figured I'd ask a follow-up question: Where is this reset button? I didn't know there was one on these receivers... Thanks

Try to hit the reset button on the receiver. I did this and it has worked wonders.

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.

Chances are there is nothing wrong with the mixer. IF you accidentally turned on Phantom power, that would cause the problem. Phantom is ONLY used with condenser mics and a few DI boxes. Turning it on can create noise unless balanced lines are used everywhere.

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.

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.

This sounds bad... I suspect that a noise suppression cap on one side of the bad channel has shorted... possibly due to a static discharge.
Test for this doing this: Using a meter, with nothing plugged in and phantom on, check the voltage at both pins 2 and 3 to pin 1 of the XLR connectors. If you find either pin 2 or 3 is much lower than its mate (they both should be 15 volts to 48 volts positive), then one side noise filter cap probably has shorted. Unless you are electronically adept at repair, take it in for servicing.

Yes this unit comes with Phantom power, but you must turn it on. The switch for this is located next to the XLR connector for channel 9 and the bottom of channel 10. Make sure that it is turned on. The LED should be lit with phantom on.

Not working

If it is brand new, it is likely "pilot error" as setting these up if you are unfamiliar with mixers can be frustrating.

There are several things that must be done to have a working system. Correct speaker cables are one and the setting of all the knobs are important...

DO NOT REPLACE FUSE. If any LED's are on, fuse is OK. If fuse blows, service the unit before replacing fuse to avoid further internal damage.

Make sure speaker cables are good.

Set the level control for the channel you are testing up AND you may need to press the "PAD" button to change the input gain. Turn up the master gain.

Depending on the source you are using, line or mic you may need to change the PAD button.

NOTE: This mixer does NOT have Phantom power and cannot be used with CONDENSER microphones requiring phantom power. You will get no audio from a condenser mic without phantom power. You must use dynamic mics with this mixer.

Can't operate my MXL 990

If it is an MXL 990 Condenser that comes in the grey case with a shockmount and a black hard mount I can solve your problem. (If it is USB I know nothing about that unit).

This MXL 990 microphone MUST have 48v phantom power in order to operate. If you aren't familiar with the term phantom power read the first link:

Phantom power -
MXL User Guide -

If yours is one of the older MXL 990's it should have an XLR connector on the bottom -
XLR Defined -

Your mixer (I am guessing its a Peavey, Tascam, Mackie) or something entry level like that may or may not have phantom power. I am guessing not. But if it does, it will have a switch that says 48v phantom power and most likely a green or red LED next to it to show you when its on. This mic will NOT work without phantom power.

Best suggestion: Verify that your mic is the MXL 990 Condenser, if it is it needs 48v phantom power. Check your mixer and see if it has 48v phantom power. The only computer soundcard that I know of that is used by a lot of folks is the M-Audio Delta 1010LT. It has XLR inputs but NO phantom power on it.

There's your answer.

(need more tracks) dp01

I'm guessing that you're asking whether the mixer needs phantom power to the mics in which case the answer is that you wouldn't need power there if the mic preamp is providing it already. You'd just plug the mixer's main 1/4" outputs into the DP-01s 1/4" inputs. The 1/4" inputs on the DP-01 are not powered anyway, only the XLR jacks can be powered by turning the phantom power switch on.
