Glad to be of assistance Ben!

Hey guys, I just found this and I was wondering if you guys ever tried this. Just curious.


Thanks and I hope to help somebody with this found.

Have a nice weekend!!

PS Thanks again Chad ;)

Here's a more elegant solution: JL-DT454 [JL-DT454] - $419.00 : juicedLink, Unique and Trusted Solutions for Audio and Video Production

This JuicedLink mixer does the same thing, but also has XLR inputs and phantom and level control & meters. You'll be left with one channel like the example you just showed. Really if you want quality audio you don't want to capture it into a DSLR. But these methods will make the most out of a bad (audio) situation.

Hey Chad,

Thanks much again for your input. For now I am using the Tascam. And I will need to use it for a while while I gather some more dough.

I added the DT454 to my B&H wishlist. It seems like a great solution.


Have you heard of this device?:

Ben I have not, but I just checked it out, and read some reviews. Some are complaining about a noisy signal, and some ground hums. I used to like Beachteck stuff, but found that Juicedlink usually has a cleaner signal path, but sometimes soesn't have all the bells & whistles like meters. I'd say the first place to start is to see if your particular DSLR can get firmware like Magic Lantern, to turn off AGC and use manual levels. Then you would not need a mixer like this. But aside from that, and you'll have to verify this yourself on any specific mixers you are considering, I have fond that previous Beachteck units I have used did not have any gain increase. They were mic level, and could only be turned down. The Juicedlink mixers could switch between mic & line level (versatility is awesome) and their levels could actually boost the signal somewhat. Maybe only 15db or so, but it outstripped the Beachteks in function and sound quality. I can't say for sure because I have used neither of these units, but I suspect that the JuicedLink is better. Again, if you can achieve manual level controls through firmware on your camera these specialized mixers for AGC won't be necessary. You could just use a regular mixer for a little cheaper.

Robert alone is basically JuicedLink, and he is happy to answer questions. If you ask him to tell you why his AGC mixer is better than Beachteck's, he will be all over it I'm sure if he's not too busy.

Wonderful, that is a great idea. I do have a Canon 7D and I cannot turn the AGC off :(

I just logged into youtube and sent Robert that question. I am pretty sure I will most likelly (unless something better or a firmware comes along to turn AGC off) go with the JL (after I make more tough), but I just like to learn more about this stuff.

I appreciate your answers, that are ALWAYS very helpful!!

Have a nice week Chad ;)

I stumbled across this ... if there is something that you need, then always best to email me at the contact address on the juicedLink website. I don't check YouTube, and I'm only on the forums once in a while ...

Here's why I would choose the juicedLink DT454 over the other device you mentioned:
- More available low-noise gain
- control of 4 mic simultaneously (instead of 2)
- Meters (instead of a single indicator LED)
- Even more important, meters that you can adjust the sensitivity (since every camera is different in terms of where the meter needs to be calibrated)
- Power saving 12V phantom power mode

Hey thanks for your answer. You sold it to me. I was going to go with it anyway, but this is exactly what I wanted to know and learn. The differences.


Have a great week and I look forward to hear more about that rig you are working on (specially its price).
