Solution #1: Use Audio-Technica PRO 88W/T wireless microphone system and Canon HF-R800 camcorder
* Load 9V batteries into the transmitter, and into the receiver
* Connect the lapel mic to the transmitter in the obvious jack on the Audio Technica PRO 88W/T wireless microphone system
* Connect the receiver to the Canon videorecorder as shown in the photo below
* Flip "on" the power on the transmitter, and on the receiver
* Now, when you push the 'record' button on the back of the Canon, the lapel mic will be recorded on video
Take the coiled two-male-ended jack and connec the reciever (top of this photo) to the videocam, at the "mic" female jacks. |
Now, 9V batteries are expensive, and wouldn't last more than one lecture. Not a great deal! So I first bought a rechargable 9V... but they have LESS time before they give out, and it seems that the battery only need be a bit undervoltage to ruin the process. I need a good 3 hrs of continuous recording. So my next attempt was to be clever and use my existing iPhone external LiIon batteries to be the power source. But these are 5VDC, so I needed to get a 5VDC-to-9VDC voltage transformer, which I got (Kundun). But apparently the circuitry inside the Kundun unit process lots of RF noise because there was a bad hum that I couldn't get rid of. Totally useless! Don't buy the Kundun units in any audio set up.
The iPhone 5, donated by my student, using OS 10.3, can record through an external mic using bluetooth. So, my next thought is to use the Airpods as my microphone, and Filmic Pro as my video software on my iPhone, and iPhone as the video recorder. Nope! FilmicPro only has bluetooth on a system that requires OS 12, and my iPhone 5 is only able to run OS 10.3 as the latest version it will accept. . I have now an iPhone SE but not enough memory to record a long lecture (hey, I saved money by getting only a 16GB version, thinking it would always be just a phone for me). A kind student, Ashlee, gave me her old iPhone5 with 64GB storage! So now I can record a 3 hour video (I think, near as I can calculate) lecture. The AirPods should last 5 hr on one charge. The iPhone itself can be plugged into my external LiIon battery recharger for iPhone, to keep it powered for plenty longer. And I'm just hoping the audio quality will be fine. I saw a video which showed that there's cut-out of audio grab at 65 ft distance, but inside 50 ft or so it seems to be OK. I plan to have the iPhone only 15 ft away during my Room 806 lectures, and perhaps 20 ft away for the Erica Schilling Forum lectures, so this should work. It's also not clear that those reviewers complaining of the tinny audio quality actually tried adjusting the settings inside the app and Airpods first. I would think that they did not, or they'd have mentioned it.
Nope. This solution didn't work for me. The AirPods fall out of my ears during normal motions while giving lectures, and also the claimed 5hr on one charge must mean for listening, not for using it as a microphone, because each AirPod dies after about 1.5-2 hrs. I returned them to the Apple store.
Next Solution: Back to using the Canon HF R800 video camera with Audio-Technica Wireless Mic
This is a short term solution, to get my most immediate lectures, until my NEXT attempted solution arrives. So, this system above will work, but barely (at least at home test, not yet at my lecture classroom). First, some notes:
--- it doesn't seem to matter whether the TV is on or off, nor how close I am to my laptop, nor how I'm oriented. I think the antenna on the receiver next to the camcorder should be perpenticular to the speaker and transmitter, but I didn't see a big effect. The on-camera mic is just not great at all when you're 15 feet away as it must be. It's too far and low S/N impression.
* Use the on-screen menu "home" icon, then the gear icon to get to the various options you can tune, and use the down arrow to get to the "mic" setting. Set it on "M" (manual) and put the level at halfway betwee 40 and 12, which is less sensitive than if you leave it on "auto" it seems.
* Use the lavalier mic clipped as close to you can, right on your collar, just a few inches from your voice.
* To set the focus, click the
