Schoeps CMBI and Lumix GH5

Friday, February 3rd, 2023

I usually record audio for my “Look At Me Play Guitar” videos on a PC and audio interface or a standalone recorder, but I understand that the audio system in the latest Lumix GH cameras has upped the quality of camera audio, especially with external mics. And I happen to have a pair of Schoeps mics designed to connect to devices like cameras, the CMBI mic bodies. Naturally I had to hook them up and see what happens.

The CMBI bodies are out of production now but they are still out there in the used market. These little mic bodies are battery powered and use a DIN 5 pin connector instead of XLR output. This configuration was optimal for DAT recorders and other portable recorders that were common in the 1970s. Schoeps created a flexible cable system that allowed mono or stereo setups, but these cables are also no longer in production. Fortunately there are cable specialists who can create functional cable sets. I had Vark Audio create cables for mono and stereo attachment and also a pair of DIN to XLR cables so I could connect to my current recorder.

Here’s the video tutorial showing the setup I used to create a video with the CMBI mics into my Lumix GH5:

and here’s the resulting “Look At Me Play Guitar” video:

It was fun rigging this setup and shooting a video with this equipment, but the capabilities of the newest portable recorders has convinced me to keep using separate audio for my videos. I’m still keeping my mind and eye open for upgrades to camera audio, it’s sure nice to be able to skip the process of syncing audio and video in post.

 


“Look At Me Play Guitar” Video on an iPhone

Friday, February 3rd, 2023

I usually shoot my videos with a set of Panasonic Lumix GH series cameras and record audio on a separate device, then I edit in REAPER and Edius to create the final clip. But I thought it might be interesting to see what I could accomplish with an iPhone replacing all the other hardware.

I have found that mic placement is really critical for decent audio recording and the built-in camera mic is rarely in the best place, so a separate mic or two really improves the quality of a music video. I’ve tried a few different gadgets that connect external mics to the iPhone and I’ve settled on the iRig Pro Duo for that purpose. It has decent mic preamps and a/d conversion and provides phantom power if needed.

After capturing the performance in the iPhone I used iMovie to edit the clip. Here’s a look at the setup and the editing process:

Just in case you’re interested, here’s the completed video that I posted on my slack key channel:

I must admit that I didn’t totally enjoy the process of editing on the phone, I expect to continue using my laptop, Lumix cameras, and separate recorder for my videos, but at least I now know that I can create content with just a phone, an interface, and a mic or two.

 


Wind Protection for the Sony HDR-MV1

Saturday, June 6th, 2015

In my comparison of the Sony HDR-MV1 to the Zoom Q4 I noted that the Zoom comes with wind protection in the form of a rather effective hairy windsock. This feature gives the Zoom a clear win over the Sony for outdoor recordings using the built-in mics. (more…)

 


A New ABX Tool

Wednesday, July 30th, 2014

At first glance evaluating audio gear seems like it should be perfectly simple, all we need to do is trust our ears. But it turns out that we don’t hear with our ears, we hear with our brain and with the nervous system circuitry between our ears and brain, all in a wildly complex network of sensing, filtering, focusing, and feeding back. And this network is both amazingly sophisticated and hilariously inept at the same time, able to discriminate between small differences but also certain to occasionally make up the answers.

Zoom H6 Overdub Mixer

Friday, February 21st, 2014

I don’t overdub, or at least I do it only very rarely. And I’ve never done a project using the overdub capability of the Zoom H6. But I do know that the capability exists and I’ve tested it briefly.

When an H6 user from the UK posted on the Sound on Sound Forum that he was having a problem overdubbing because phantom power was not available, I did a quick test and learned that my unit exhibits the same issue. (more…)

 


Zoom Q4 vs Lumix GH3

Friday, February 14th, 2014

Talk about an unfair fight, this seems to be just that, based on price alone. The GH3 currently costs around $850 (Ooops, today it’s $1000 – camera prices have become highly variable it seems) for the body only, the original price was about $1300 with a kit zoom lens. The Q4 at $299 is a lot easier to fit into most budgets. And we’re talking about a very specific niche here, the “music camera,” in this category the audio quality is right up there in importance with the video. (more…)

 


Lumix GH3 Audio vs Zoom H6

Thursday, January 23rd, 2014

I’ve been using my Panasonic Lumix GH3 as my main video cam for the last year or so and it’s a terrific tool. The articulated display, live HDMI out, high bitrate codecs, WIFI connectivity, and luscious image quality have made it my favorite shooter. But I’ve avoided using camera audio even though the GH3 does have some intriguing audio features. (more…)

 


Rode NT1a vs ADK A6 plus Two

Tuesday, March 5th, 2013

There are a number of comments I expect to hear when microphones are discussed. Someone is likely to call the Rode NT1a harsh, strident, shrill, or some similar indication of high frequency problems. And when asked to recommend a mic for recording acoustic guitar, the ADK A6 is one of the more common responses. So how obvious are the differences between these two mics in a four way blind comparison? (more…)

 





About the Blog

    Howdy, my name is Fran Guidry and this is my Homebrewed Music blog.

    I play Hawaiian slack key guitar and recorded my solo acoustic CD at home. Most of the recording information I find on the internet seems focused on bands, drums, multitracking, and so on but my main focus is recording solo acoustic guitar. Lately I’ve been enjoying video recording along with audio, so that shows up in the blog as well.

    I’m also a guitar nut. I love big ones and little ones, handmades and factory guitars, cheap ones and expensive ones. So I’ll be sharing the fun of exploring guitars as well, along with the challenges of amplifying acoustic guitars for live performance.

    Welcome!

Philosophy

    My recording philosophy is pragmatic, skeptical, not super critical. After all, the performance is by far the most important component of a track, and every aspect of any recording is a matter of taste.

    But I do like to know “about stuff.” Back in hifi days I learned about double blind testing. I learned that we humans can easily hear differences that don’t really exist. The more I’ve learned about our human auditory system, the more I’m skeptical of what people say they hear, especially if they claim that a particular microphone or preamp or cable has some magical property.

    I’ve only been recording since 2001, and when I started I found the usual places on the internet. I sought advice and accepted it, thought I would improve my recordings by using more expensive equipment. It didn’t work.

    Two things that did seem to lead to better recordings were experience and room treatment. Getting an appealing sound is the combination of many small details, and learning those details only comes from experience. Amd the sound of the recording space is obviously a big factor.

    I’ve only recorded seriously using digital technology, but I remember trying to record rehearsals and gigs back in analog days. I don’t have any nostalgia for analog recording and playback systems at all. I think even low end digital systems can capture marvelous recordings. So when I look at gear, I look for good specs: low noise, broad flat frequency response, wide dynamic range, low distortion. I’m not interested in colorful components, mics and preamps with a sound, I want the sound to be the sound of my guitar.

    But the last word is that I’m just learning and I hope you find something useful in my posts.
