T3i phantom power at DVinfo.net

Alex Anderson · July 12th, 2013, 03:33 AM

Does the T3i provide power to external mics that can use it when they are plugged into the mic input? And, can someone confirm that we can use a 3.5 stereo Y adapter to get two mics in with one going to the left channel and one to the right channel? The T3i manual does not say anything about this as far as I know. I am aware of other ways to do audio with a double system. I just want to know if I can get two lavs powered from the camera and recorded on two separate channels, L/R.

You should not be recording directly into any Canon DSLR. There is hiss on the track no matter what you do.

Gary,
You forgot to answer my questions. Do you know if if the T3i provides power to the mics thru it's mic input?

Alex: I cannot speak to the T3i because I only own the 5D MK 3 and the 60D. But I can tell you neither of them have phantom power, and my guess is the T3i doesn't, either.

As far as recording to the camera is concerned, I disagree with Gary. I record interview audio all the time to my MK3s and I have tuned the hiss out by lowering the audio gain (in manual mode) to just a notch or two over the lowest setting and controlling the input from my wireless mics. Even with studio headphones on while recording and editing, I do not hear any hiss. But I backup my audio with a Sony audio recorder, just in case. You never know.

Obviously, the MK 3 is my favorite for recording audio because it has a headphone-out jack. I don't use Magic Lantern.

Now, if you're recording audio for a feature film or serious documentary, you really need a soundie and crew to record audio separately. You'd be asking for trouble if you recorded to a camera, even with a $60K camera that has XLR inputs and phantom power.

thank you Charles. I appreciate your input.

No worries. And I forgot to mention I have used a Y cable to input two separate wireless mics, but I have not used two stereo sources. Two mono inputs work fine.

charles-

if i may ask:

the two mono inputs were placed on both audio tracks as mixed not separate tracks, right?

thanks in advance.

be well.

I must have confused some clips because I went back to an old project that I used the Sescom cable from my DR-100, and you're right, the hiss is about the same as on the Tascam track, so I stand corrected.

Correct. The tracks were mixed. Sorry I din't make that clear.
