When you say working in some places but not others, do you mean it works on some channels but not others?

I'm sure you are aware that condensers will not work without phantom power. I'd suggest trying your mic through a different system (if there are non available try your local music venue, if you ask the engineer nicely I'm sure he'll let you test it on their rig). Also try a diffenent condenser on all channels of your mixer, and also try a dynamic mic as well just for thoroughness.

I can't really give you an answer to this unless you've tested with other equipment to identify which part of your rig is faulty.

To be honest I wouldn't be surprised if it was your mixer, I've always found behringer gear to be pretty crap quality.

Also it might be a stupid question but have you tried using a different cable?

SOURCE: 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.

SOURCE: I just purchased a MXL 990 condenser mic.

Phantom power comes in different voltages. Make sure your power supply is delivering enough. Also make sure that your mike cable is wired properly. 1 is ground or shield. 2 is hot or Ve+ and 3 is cold or ve- If 1 and 3 are bridged for unbalanced use or if you have a short it won't work and will probably damage the mike or the power supply. I think the power supply needs to be 48 volts and you have to use the stereo XLR cord that is recommended for it. I hope this helps.

What is a mutli purpose condenser microphone


It would be a good mic for that. It does require phantom power, like alomst all condenser mics.

\berenger microphone not working


Since you did NOT give us the model number of the Behringer mic, we can't do much to help... HOWEVER many of the mics are "condenser" mics that REQUIRE "Phantom" power from a mixer or preamp. These will NOT work without the phantom power being supplied. Look up your model number and see if it might be a condenser type.

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 a lexicon alpha, samsung CO1 condenser mic and a samsung phantom power box, i have all the correct wires but i dont think i am connecting the correctly, HELP ME ! lol


Sorry, but the Alpha does NOT have Phantom power which IS required for a condenser mic.

You will either have to get a mic preamp that supplies phantom power or go to a dynamic type mic if you stay with the Lexicon Alppha.

Phantom power will not wor on my phonic 620 cd jacks will work but when i plug in a mic it will not work help


I assume you are using CONDENSER microphones, as these are really the only ones that can use Phantom power. Also do NOT use any MONAURAL connections to MIC jacks while using Phantom power.

Im having a problem with hearing my b-1 studio condenser mic on the lexicon alpha progam?


Sorry but... Very simply, you CANNOT use a condenser mic with the Alpha since it does not supply the required Phantom power for the mic. You must step up to another interface to use condenser mics. You can use dynamic mics with the Alpha or other audio sources. I use a Roland/Cakewalk UA25E interface with condenser mics and also the Lexicon Omega which does have Phantom power for the mics..

Condenser microphones need phantom power (48V) to operate. Some condenser mics use batteries to work and get around using phantom power from an audio mixer. hope this helps

Using the Shure AMS22 with a 7V stable power source into a reg


These are a condenser mic which requires a very high impedance FET amplifier right near the condenser part. Most wired condenser mics use Phantom powering of the internal amplifier AND balanced line driver.

I would NOT recommend you try modify this unit for wired operation.

Incidently Phantom powering is usually at least 9 volts.

I have a shure microflex mic condencer 150 the led does not work and the mic is dead. Does the mic need a battery if so how do you instal it.


Try using a mixing console with phantom power ( + 48 ). A condenser mic needs 48 volts to operate. The led should light when the XLR microphone cable is connected to a console with phantom power.
