In this Part II Audio Tutorial, Robert from juicedLink and I talk audio recording solutions for the Panasonic Lumix DMC-GH3 Mirrorless Digital Camera using a Preamp like the juicedLink RM333 Riggy Micro. For Part I on the Blackmagic CInema Camera (( click here )).
The Panasonic GH3 has added headphone monitoring directly into the camera, where the GH2 suffered in this area of audio recording. This means that purchasing a preamp (for better signal to noise audio recording) can be more cost effective since users now have the ability to utilize a smaller preamp like a juicedLink RM333 Riggy Micro, rather than the larger RA333 Riggy Assist Low-Noise Preamp that provides audio meters. A preamp like the juicedLink RM333 allows you to throttle back the noisy gain from the camera and replace is with clean gain from the low-noise preamp. Robert explains that you’ll want to set your GH3 to the lowest gain setting and leave it there in order to capture the best sound quality.
With the RM-333 Preamp, you also have the ability to use quality XLR microphones with your GH3. The RM333 provides Phantom Power and an Audio Output Bracketing Option. Audio Output Bracketing is a camera overload protection technique to prevent your in-camera audio recording from clipping. Here’s how this works: you’ll want to mix your mics together, set to mono then attenuate the right channel. You’ll have two tracks recording the exact same thing from your camera with one track recording at about 16Db lower. This way, if one track blows out the audio recording, there is a safety file saved that you can pull out in post.
