wireless receiver/transmitter for Canon Vixia HF R82
Hello all,
I do simple video for corporate presentations, talking heads etc. I am not a video or audio professional. I’ve got a Panasonic HMC40 video camera with XLR adapter and use the Sennheiser G3 wireless kit to input speaking audio into one channel of the camera. I then use a Rode shotgun mic on camera to capture ambient sound, crowd reaction etc. I do the video and audio post with Final Cut Pro 7.
The above is a capsule of my video/audio background.
I’ve been asked to consult for a local organization that captures various speakers presentations for their website. The person who has been asked to capture the presentations is using the organizations Canon Vixia HF R82 consumer video camera. They have been recording from the back of the presentation space, which seats several hundred people. The person has only been using the internal microphone of the Canon Vixia, and obviously, the audio is very poor. The presentation hall does have a PA system and uses it for these presentations. I have not been able to look at the PA system yet for a possible monitor mix audio out option. This audio out from the PA board possibly could have a wireless transmitter plugged into it and the signal sent to the Canon Vixia via a wireless receiver.
My question is this, the Canon Vixia only has what looks like an external mic port that would accept a 3.5mm plug. Is there any way to use this mic input to hook a wireless receiver up to receive a signal from the PA board transmitted by a wireless transmitter?
I’ve got a bunch of different types of cords and have been experimenting with an older Sony Hi8 camera that has the same mic input as the Canon Vixia. No matter what I try I can’t get the Sennheiser G3 transmitter/receiver to talk to each other.
Any suggestions?
Thanks.

I’m not sure what you mean by “No matter what I try I can’t get the Sennheiser G3 transmitter/receiver to talk to each other.” Does the receiver show an input signal? Does it work with a lav? Same frequency I assume.

Hi Bob,
That is correct. I’m not getting an input signal on the receiver. Yes, the transmitter/receiver are on the same frequency.
They work fine with my Panasonic HMC40, but the Panny, with the XLR adapter is designed to accept wireless input if necessary. Just wondering if I can get a wireless audio input using wireless transmitter/receiver with a consumer camera like the Canon Vixia HF R82 utilizing it’s microphone input. Yes, my lavalier works when I plug it into that input but the plug from the lavalier has to be seated just right. If you turn it round in the input the audio can go off and then back on again.Thanks.

Hello. Dennis. Lets start from the front. When you turn on the G3 system. Does the receiver show a full level on the RF meter? If not, that’s where the problem is. If there is a good signal, then I would say you have an input mismatch between the receiver and the camera. If the camera can take an external microphone, then you should be able to use the G3 with a 3.5mm cable. Test your cables and make sure they are good.

Hello Dennis,
The input of the camera is stereo. You need a specially wired cable to feed the mono output of the G3 into the stereo input of the Vixia. It wold not look any different than a typical cable. It would, however be wired to take the + (tip) side of the mic and apply it to both the tip and ring on the other end, which you would plug into the camera. The audio would then go to both Vixia channels.
Right now, you’re effectively cancelling the audio out by feeding the positive peaks to one channel and the negative peaks to the other channel of the Vixia. Test this by using a stereo input to the Vixia.
If the audio jack on your camera is a four-pin design, you may or may not have other problems.

Take a look at page 118 of this manual. https://gdlp01.c-wss.com/gds/0/0300025910/01/vixiahfr80-82-800-im-en.pdf
The external mic input is 3.5mm.Ty, maybe this would work? https://www.amazon.com/C2G-Cables-40634-Adapter-Metallic/dp/B000O7AW98/ref=sr_1_10?s=electronics&ie=UTF8&qid=1519773739&sr=1-10&keywords=3.5mm+mono+to+stereo+adapter

Hi Bob,
For $8, it’s worth a shot, but the reviews are a little shakey.
