Panasonic GH3, Audio-Technica AT875R & M-Audio Firewire Solo setup
I'm trying to work with items that I already have, which are all in the title. I'm not a filmmaker or a sound tech (obviously), just trying to make better home videos. This setup would be used for talking head interviews.
Rather than use the GH3 onboard mic, I upgraded to the AT875R. This mic requires 11-52V phantom power and its "XLRM-type connector is low impedance (Lo-Z) balanced."
I THOUGHT I could use my old M-Audio Firewire Solo for phantom power/preamp. The Firewire has a mic-level input on a balanced XLR connector, +48VDC phantom power, and mic input gain for over a range of 0dB to +40dB or greater.
I connected the mic to the xlr mic input on the solo and from the balanced line output (1/4" TRS) of the solo, I connected a shielded audio cable (1/4" stereo to 3.5mm mono) to the GH3 3.5mm audio input.
I'm recording with the GH3 using .mov/24p/50Mbps. The GH3 onboard mic is set to 1. This setups audio works and sounds much cleaner than the GH3 mic, but the signal is very low. It audio also gets distorted if I get close to the mic, though the levels don't get hot. I'm not sure if that is to be expected. I need to be at least 12" from the mic to minimize vocal distortion, but regardless of mic placement, the audio is too low. I have the gain on the M-Audio turned all the way up. By nature of the M-Audio, everything through the XLR is going to the left channel.
Questions: I'm trying to save myself $$. Can I continue with this setup? Is there a cheap product to boost my audio? Or should I just get one of these juicedlink type products that I was hoping the Solo could serve as a replacement for...?
Also, if all the audio is only going to the left channel, do most people simply use some kind of split/duplicate option in their A/V editor to make it sound stereo---or is this simply another reason I should lose the Solo from my setup?
Your assistance would be greatly appreciated! Please be kind!!
