According to what I've read so far, the higher end XH series camera has a serious oversight (in my opinion) regarding the choice of signals on the mic/line XLR connectors. It appears that they operate in tandem. If you select line, then both connectors are in the "line level" mode. Visa versa for mic level select. Obviously, this is s short coming and puts a real crimp in field acquistion.
Anyone know if the "A" or "G" series cameras have the same issue?

thx

Both the XLR Ch1 and Ch2 do operate in tandem on one line/mic switch in the XL H1, and it appears that the XH series uses the same swtiching scheme for XLR input.

If one cannot arrange to input to both XLR inputs as either mic or line level, and must have the camera accept XLR line level in one channel and XLR mic level in the other, Canon cameras may not be the right choice. I'd think this would be an extremely rare circumstance, though. One could either use two mics connected onboard OR just pass both signals through a sound board at line level, as required, rather than do one of each.

I don't see that as a problem. There are times I will use a camera mic to record ambient sound, while the person I'm shooting will have a wireless lav or I'll use a shotgun mic through a mixer. The mixer can provide line or mic outputs. If I mic directly to the camera, then obviously the mic input is used.

The only situation I can think of where this might be an issue is if you were shooting some event where you took a house audio line feed and want to run a camera mic at the same time. I have done that numerous times. However, in all cases, I take the house feed into my mixer (it would be folly not to, in my opinion), and in that case I can always take mice out of the mixer. So, unless you have a mixer that only gives you line out, I don't see how it could ever be a problem. If you wanted line in for the remote mic, run a cable from the camera mic to the mixer and take both of them as line in.

For $35 you can get an in-line pad that will take your line level and knock it down to mic level.

Thx for the replys gents.
However, I want separate input switching. Been there and done all the suggested ways.
IMHO there is no excuse for this design oversight. Well, maybe two. Either there engineers need to get out more, maybe actually USE a camera, or the company really is saving 2 cents on the switch for every camera. That adds up you know!!

What kind of situations do you shoot in where you have to have line level for one input and mic on another?

Well, that's a particular feature you want and Canons don't do it. It's not a concern for the vast majority of us. If none of the suggested solutions would work for you, you'll have to shop around.
