Question About Phantom Powered Mics & EX3
Having never used a mic that uses phantom power, I have a question.
Using a mic on the EX3 that uses phantom power requires nothing more than switching to +48V, and the mic draws power from the camera's battery is that correct? |
Perfectly correct.

Thanks, Jon.
How much power consumption does a mic put on the battery? Is it significant? |
Nearly none at all. I can't tell any difference with my mic. Bear in mind, a lot of these mics optionally have a battery compartment. A single AA battery can power the mic for weeks.

And I selected the Rode NG-1 because it was small due to no battery compartment. EX3's phantom power does its job and it works well and I don't notice any increased battery draw.

Jay, this chart is a good place to start to see what brands and models of mics draw in mAh from the phantom power circuits. Some mic pre's are not very robust in their voltage reserves and can cause all sorts of anomolies if they are loaded down with a power-hungry mic.

Be aware though, the CS-1 has a quite narrow pickup, remarkably so for how short it is. |

Bear in mind, there are two different K-Tec styles - the regular and the short. The short one has the brackets much closer together and that is what you'll want for your mic.
