PHASING A MICROPHONE

When you buy a new or used microphone don't forget to check the phasing with your other microphones. In the past Sennheiser have supplied 2 new MKH416 microphones to me that have been out of phase. This will give you confusing problems when you are working with just 2 or 3 microphones

You can check the phase of microphones by humming into the 2 microphones.
In a mono mode, when you bring up the level of the second mic to meet the first, the signal will add if in phase, but if there is a dip in the level when the levels meet, it is out of phase.
If you are checking a Miniature Electret with a Shotgun mic put the Electret by the capsule not at
the end. Note : The capsule on a shotgun or rifle is situated just before the side vents.

TO CHANGE THE PHASE

Miniature Electret Lavaliere Microphones with plugs fitted for Radio Microphones will need the plug reconnected

You can change the phase of a Dynamic or a Phantom Powered Condenser Microphone at the 3 pin XLR by reversing the connections on pins 2 and 3. If you have either microphone you need to work out whether it is better to change the microphone or the Recorder or Mixer

TO CHANGE THE PHASE OF A T POWERED MICROPHONE OR IF IT IS NOT WORKING

On all T powered Microphones reversing the connections on pins 2 and 3 of the XLR, the microphone will either work or not work. With the microphone connected with a one to one lead, plugged into the recorder or mixer, if it works but it is out of phase you will have to send the microphone to me to change the phase at the capsule end.

If it is not working, reverse the connections of pins 2 and 3 on one end of a microphone cable and test it again, or use a phase reversing adapter, if it is still not working you can send it to me for repair, and if possible a good microphone to phase it to.

It is always better to have all your microphones adjusted to the same phase, than have phase or power reversing adapters or different pig tail leads for different microphones, or when the pressure is on you will always end up with egg on your face.

Good luck
