Phantom Power

[imageonepictures]

Hey,

Just learning what this is... so the battery on my DVX100 supplies the power? Can this work on my Panasonic DVX100 (original).

I was thinking of a Rode NTG-1.

Your camera, powered by the battery, will provide power for external microphone(s). I currently have teh NTG-1 and have to use the phantom power.

Hey,

Cool. Thanks:) If the Panasonic DVX100 (original) have phantom power how do you activate it? How does it know when to use phantom power or not?

This was something I was wondering about. Should I go the phantom power route?

With most adequate mics you either have to have phantom power or may possibly have the option to use battery power. The general rule though is when you have phantom power available - use it. A multitude of devices from cameras, mixers, and recorders supply phantom power.

I "think" (i'm an HVX user, but I think its the same) there is an on/off switch for inputs 1 & 2 under the LCD along with Channel 1 & 2 assignments.

Always connect the mic then turn on the phantom power. Then turn off phantom power before disconnecting the mic. Removes any risk of bad things happening.

For using one mic the simplest thing to do is to plug that mic into Input 2 (make sure input 2 is set to mic and not line level), then set both channels 1 and 2 to input 2. Now if you set Ch 1 levels to whatever you deem appropriate, and Ch 2 a bit lower, any loud noises that distort on Ch 1, will hopefully be at acceptable levels on Ch 2. Now you've got some backup. Now you dont have to ride the levels which is a bit of a pain to do while your trying to run the camera.

Hope that helps.

You are correct.:beer:

Thanks for your help with this.

In addition, condensor mics need phantom power, dynamic mics and ribbon mics don't. You cannot use a condensor mic without phantom power, as it relies on that extra couple of volts to pick up the signal.

i was always told not to use phantom pwr it was always best to use a battery in the mic. my 51xt plug in transmitter also has phantom pwr should i use it there to rather than the 9v?

I can't remember where I read about this, but apparently there's a spec for the amount of power available to the mic from "phantom". That spec includes a maximum current draw. Some mics draw more current than allowed, and so will work better with a battery. Others are within spec and will work fine either way.

Bottom line, so far as I am aware, is that if the mic is within spec the sound will be the same either way. Phantom power certainly has an edge in convenience.
