Rode says their NTG-3 draws 4.3mA, using phantom power (+48v).

Would someone please translate that for me, please. What exactly is that telling me? Will that kind of power consumption have an adverse affect on the camera's (EX3) power supply?

Thanks!

It tells you 2 things. First the mic is a condenser type which needs a voltage applied to it to run. this normally come from a battery or an external "phantom" power supply, like from a mixer or in this case your camera. Secondly it tell you the mic will draw an average of .0043 amps of current.

This will really will have no bearing on the operational time of your battery, the camera itself pulls probably 1 - 2 amps so a few thousanths won't make any difference.

Hope this helps,

Hope this helps...

Jeff, that helped a geat deal. I learned something new today. Thank you very much!

I like your tagline, too. I consider myself to be about a "common" as a fella can get.

Jeff's right.

Probably more than you want to know, but the formula for power is P=IxE...easy as PIE.

P= power in watts
I= current in amps
E= volts

Because the mic requires 48 Volts DC, and your camera probably 12-16V, the camera will probably have a circuit to step up the 12-16V to 48. That'll chew up a little more power, but you'll still be fine.
