Denis:

In case Jon doesn't get to you, preamps are going to get you cleanest sound. In order to get a usable level of sound, whether going into camera, and/or in boosting after the fact, the low noise provided by a good preamp is highly desireable. The JuicedLink provides that benefit. Pushing the camera gain up, will result in noise levels that aren't desirable. Whether your set up qualifies as a preamp set up is another issue.

I can get more preamp boost, at the expense of portability, with my ENG44 field mixer, but for on camera recording, I don't see another reasonable alternative than to go with a preamped XLR Adapter like the Juiced Link.

Hello Chris - The wireless puts out a pretty high level and is adjustable, its small and I already own it ( the best feature of all).
I need a plug out of the 5D to two mini XLR connectors and my wiring friends want to know if there is power in the circuit which will require capacitors to be soldered into the connector.

Denis: There is no phantom power from the camera. That's another benefit of the Juiced Link, it provides phantom power up to 48 v. You would have to adapt to mini xlr out of the Juiced Link, (edit ) -> but it sounds like you are not looking for power. This is is simple mini plug input. Are you planning to use Magic Lantern to enable metering ? You will need to, in my opinion, in order to get your levels right, and to monitor out through the AV Jack.

Denis,

The 5D has a +5V supply for electret mics. It's still enabled with the ML firmware. Hopefully, we'll be able to turn it off in a future revision.

And, yeah, if the signal from your receiver is hot, no preamp is required. I'd go with a couple of transformers for impedance matching and solder a short, custom Y-cable to connect to the 5D. AC coupling would be good to preserve the 5V supply, but is probably not needed. I believe that the supply is behind a series resistor to protect it.

Oh, you wanted it turned off? That's easy enough to do. I'll add it as a config option in 0.1.5.

I missed that, sorry.

Sweet! That should reduce low frequency noise slightly.

Good news, everyone! Magic Lantern 0.1.5 partially supports HDMI output, which has the advantage that Canon's software assigns it a higher priority. So you can leave your DP1 and your headphones plugged in all the time to the camera when switching to and from Magic Lantern.

Tramm,
I hope you'll forgive my ignorance of HDMI, but what does "partially supports HDMI output" mean?
Are you able to pass full res output to an HDMI monitor?

Parts of the Magic Lantern interface are off screen on an HDMI monitor (like the left audio level) and the zebras/crop marks do not line up with the correct locations. The next version will have full HDMI support since I have a Small HD DP1 to experiment on.
I'm working on it. I can switch it to 1080i for a frame while recording, but the Canon software switches it back immediately on the next frame. This resolution switch is also messing up the functions like zebra stripes that need to overlay the YUV video stream.

In the meantime, I find that if I set my video monitor at "Normal" on a cheap HD TV i bought a while back, when the camera begins recording, I do get a relatively decent aspect ration representations. You should test out different configurations with you chosen video monitor, to see which on works best for you.

Thanks much - for both the answer and all the awesome work you're doing. Your ML is about to make a bit of money for the folk at Small HD.

I've been looking into the Marshall, Ikan and a few others, and Small HD seems to have the best price/feature/quality ratio. The Marshall was a close second - largely based on viewing angle.

And thanks, Chris, for the advice. I've not had my hands on it, but I think the Small HD DP1 will be good for not only my 5DM2, but also general usage with my XL-H1 or my potential future camera of the Sony EX1 (if I can ever justify the expense).

Thanks again.
