Headphone output on CANON 5D Mrk II-Special Mini Jack?
on Sep 1, 2009 at 1:14:09 am

Does anyone know what is necessary to monitor the Audio out of the 5D Mark II, I'm trying to use a JuicedLink CX231 with it. The 5D has an Audio/Video out but I get a Loud hum/noise on the left than on the right if I insert it halfway. Inserted fully then sound is only on one side. Would I need a headphone amp to use headphones?

OK further research revealed THERE IS NO HEADPHONE JACK on the 5D MII, what an oversite. It also appears you need to use 3rd party firmware from MAGIC LANTERN to monitor the Audio levels and turn off AGC, and replaced it with digital gain fixed at +12 dB and analog gain at +10 dB. Magic Lantern also adds a stereo audio meter to the top of the rear-panel LCD display during video recording, as well as crop marks for 16:9, 2.35:1 and 4:3 aspect ratio video. There's also an on-screen indication of overexposed areas of the video which functions in near-real time, albeit with no manual control over the exact threshold at which the indication is triggered.

BUT WHAT ABOUT HEADPHONE MONITORING with my Juicedlink CX231, which by the way has no headphone capability like it noisier competitor from BeachTek. How can I monitor the audio with Headphones in this configuration?

Since others have done it so well, I'm resisting the urge to get on a soapbox and preach that using the 5D as a video camera... while doable... is really using the wrong tool for the job. It's a great camera, mind you... but in the real world it's a wrench when you really need a screwdriver. Oops, I guess I was preaching anyway.

All that being said though...

I don't know of any way to actually monitor the sound that is being recorded, but it's fairly easy to at least monitor what the mic is picking up. You can just use a regular headphone amp like most sound guys (especially boom operators) use. We use the Shure FP12. We've had this one forever, I wouldn't be a bit surprised if you can't even buy this exact one any more, no doubt a newer/better model has replaced it...



With this guy, the mic plugs into the box (it has a belt clip, usually worn by the boom op), and then with another XLR cable you connect the box to the camera. Except of course in this case you'd use and XLR cable to connect it to whatever mic connection device (a little Beachtek or whatever) that will allow you to connect it to the camera. Your headphones plug into the box, where there is also a volume control. The box will take either XLR or quarter-inch mic inputs, and has both quarter-inch and eighth-inch headphone jacks. It will also pass through 48v phantom power if you are using a higher-end mic (such as the MKH416, etc.) that requires phantom.

Again, it doesn't let you monitor the audio that's actually recorded, but will let your sound operator at least know what the mic is picking up and whether it's good on that end.

I think though that if I were going to try to use the 5D for video and there was substantial sound recording needed... I would just go with double-system sound rather than single system... and record sound to a separate audio device. It could be as easy as one of the newer flash-drive audio recorders... or even an old Nagra deck if one is laying around. At least the sound guy would be able to truly monitor recorded sound, and have it in an easy-to-use form after the shoot.

Sound advice, no pun intended. I guess trying to monitor the actual audio from the camera is non-existent for now. And yep I kind of agree that the DSLR while a COOL concept it's NOT quite there today. For now I'll just use my Fostex when we shoot, so much for the Run 'n gun!

I did that on their cheap Canon ZR500 I think. It had a humming sound but I can hear that the external mic was picking up. I just needed to make sure that it was picking a sound and that the battery in the mic has not died. I have a Panasonic GH1 and I can only hear sound on playback, not during recording. I bought an adapter for the av plugs that came with it and plugged a headphone on the other end.

If you use the Magic Lantern firmware, you will have usable audio out from the "A/V" out on the camera.

The 4-conductor plug is in the following configuration, with the colors referring to the colors on the A/V cable supplied by Canon:

Tip = Left audio (white)
Ring 1 = video (yellow)
Ring 2 = common sheild
Sleeve = Right audio (red)

This is a very unusual configuration, and it means that simply plugging in your headphones will not work. But if you use the Magic Lantern firmware, the signal is there and you can monitor what is being recorded by the camera, whether it is from the camera mic or from the camera's input jack. I used an adapter to re-combine the white and red RCAs on Canon's A/V cable (left and right audio) into a stereo mini jack, which I can then either plug my headphones into (I actually never do this, not sure if there's enough volume there) or send to my mixer's return audio input.

Sending audio to the camera is a different story. Make sure you go into the Magic Lantern menus and turn every gain, digital and analogue, down to 0. Otherwise you will get buzz. Now, use a real mixer to feed the camera the level that the camera expects (it's some sort of weird prosumer level, like -14db). If you don't use a real mixer, you will get buzz.

Somebody should start to sell an audio adaptor, some sort of jack plug for a standard hearphone so to plug a normal earphone into the 5D. There are so many gimmicks around for 5D.. wonder why nobody thought of this

Maybe this might do the job? I am considering to buy it myself:

maybe this is what you're looking for

http://www.sescom.com/product.asp?item=DSLR-5DMKII-HOCF

its specially made for Magic Lantern users and uses the AV jack, turning it into an audio jack, so no more video monitoring will come out of there, but it allows you to hear from both sides of your headphones. There are similar things for the USB port too.

So that Magic Lantern firmware sounds intriguing, and I'm going to look into it, but it sounds a bit intimidating to me.

I use a Sony Wireless that I mount the reciever on the top of the camera, and the output cable is a right angle mini that plugs into the mic into the 5D. I monitor the output of the wireless reciever (there are two outputs, an audio out and a headphone), to make sure there are no rf hits or other bad audio qualities, and just occasionally look at the connector to make sure it's still firmly seated. (I've already had to redo an interview because I plugged mic into AV jack by mistake...that will never happen again.)

I don't mind the auto gain with the wireless. Heres a sample of what it sounds like in an interview situation:
