DIY Audio Monitoring DSLR Adapter & Install Magic Lantern - tutorial - PROlike #3

Hey everybody, welcome PROlike gear where we make builds for your set – looking and working like professional products – but being inexpensive.
My name is Jano Kaltenbach and once again I’m very proud to present you a new episode. I must admit that I am very happy about your feedback the number of viewers – thank you very much and let’s go!
Last week I saw an adapter out in the internet that gives you the possibility to connect headphones to your DSLR or videocameras without a headphone jack to monitor your audio.
Sound great. When you are recording sound through the camera this is a must have for every filmmaker. But there was a hitch. The price! 45$ is a lot of money to spend for a little cable.
check out this: my own DIY version to monitor your cameras audio: costs me – 3,50 €
How it works? Well it’s very simple: we just use a connection cable from the audiovisual connection cable of the camera to a 3,5mm headphone jack!
Let’s go directly into building process so you could see that it is a very simple and inexpensive solution!
I bought two 3,5mm jacks and a “3,5mm headphone jack on stereo RCA adapter” at my local hardware store. Also I found a short cable, 3 wires at minimum, lying around.
So I could build a connection between the two 3,5mm jacks. I think for some more money you could also buy the finished cable, but I decided to solder it myself.
I simply connected the three wires on the one side to the one on the other side and attached the jackets. Finished!
A soldering work of 5 minutes – and my soldering skills are very bad.
Well, we plug the parts together and end up with simple solution for connecting RCA audio cables to our headphones.
Okay, this was the technical part – you saved over 40$ right now. There is still a step missing, because you may already notice that the display of a Canon DSLR turns off by connecting to RCA.
To disable this function, we have to install the magic lantern firmware which gives you endless possibilities and functions of a real film camera. So let’s check out how to install it!
I am using my T2i for this demonstration, but the install routine is the same on the other Canons. By the way this no official Canon firmware, so you’re doing this on your own risk!
procedure is very simple today. First we have to download the newest Magic Lantern firmware (LINK) to our computer and extract the folder. Then we place a fully charged Canon Battery into our camera! This very important.
Next step is to format a simple SD Cart in the camera, going to “menu” and “format”. Also you have to “clear settings” like picture styles.
Now we plug the SD card into our PC, using a card reader and copy the whole folder of the magic lantern firmware into the main folder of the card.
Then we switch the camera to manual mode and put in our SD card. We boot the camera go again to “menu” and enable “firmware update”. And a few second later you can see the green SUCCESS screen.
So put it off and back on – magic lantern is now running and can be accessed over the trash bin button.
Well that’s everything! Now you installed magic lantern on your 550D, running from the card. If you are using a different card, you have to do the same steps again. It is only installed on the card!
To uninstall it, you just have to hit the firmware update button again and follow the instructions – do not simply delete from card.
So this new firmware has a lot of new functions, a lot of them I never touched before. I think I could cover a whole episode with it - if you want to?
But for the time right now I only want to show you how to disable the monitoring turn-off of your camera.
We hit the trash bin button and switch to the audio menu. There we can enable the function 'monitoring USB'. With this settings we can use our headphone during viewing the LCD. A great and important function.
To just give you an overview what is also possible: You have funcitons like 'focus peaking', changing the ISO rate detailed, you can add internal letterbox and of course you can enable leveling audio and turn off the AGC control.
So lots of functions, lots of possibilities, check them out for yourself. We see us again in the next episode, thank you very much!
