Juicedlink cx211 is Making Me Pull My Hair Out! Need More Volume!!

I've been raging over this for a while now. A little while ago I made a post on here asking for preamp suggestions. I finally went with the Juicedlink cx211 for it's price and I know that Juicedlink is pretty popular. At first I liked it, but after using it for a while, I'm about ready to pull my hair out over this! I can NOT get the signal anywhere near line (or even audible) level. The cx211 has a gain switch that lets you choose between "low," "medium," and "high" as well as a trim knob for the input. Herein lies the problem:

If I set the gain switch to "high" the audio clips out on the preamp very easily. This is most annoying. Seriously, even basic talking clips out. I learned this the hard way when doing a short. Sounded fine on set, had to boost the audio in post quite a bit and it started clipping out at -6db to -10db, not good.

Okay, so I just set the gain switch to "medium" and all should be hunky dory. The problem is that at that point you have to boost the trim knob to it's max, and even then it's not loud enough. I tried a test with these settings just now with my mouth literally on the mic and had to boost in Cubase by almost 30-40db's. With the gain switch set to "medium" there's simply no way the level comes even close to loud enough.

Generally, this can all be cured by the next step (it's very jury rigged). When recording audio I take my SGM-1x shotgun mic into the cx211. That then runs out to a Tascam DR-1. I figured at this point the recorder shouldn't really matter. The preamp should boost the mic up to line level and you just need something decent to capture it with. The problem is that the loudest you get on the preamp without clipping is -20db's at the MOST. So, I have to run the preamp into the mic preamp on the Tascam and use the Tascam to boost the signal even farther. This is an audio NIGHTMARE.

As you can imagine, this nightmare gives me a metric nut-ton of noise. It's very annoying and very glaring on the final video. Does anyone have tips for this? I've tried new batteries and cables for all of my devices, still problems. Is this a common issue with the cx211? Any help would be greatly appreciated.

Thanks!
 
The preamp should boost the mic up to line level

Page 12 of the manual says...
Output Signal
The output of the juicedLink is an amplified mic level signal. The juicedLink is not intended to drive line level signals. It is not necessary to have a lot of gain to interface with a camcorder. You want just enough gain to be able to throttle back the noisy camcorder amplifiers, to yield improved signal-to-noise performance while recording fine audio detail. To much gain would overload the camcorder.

You said you were recording to a Tascam DR-1. But you didn't mention whether you are using the mic input or the line=level input of the DR1? If you are using the line-level input, then that would appear to explain your symptoms.
 
Well, I was wrong about boosting up to line level, my bad...but in either case I feel my levels are way too low. I tried every input on the Dr-1 with the exception of mic 2, which I literally just now tried...and ironically it works much better. I've never thought to use this input before because I don't like running adapters unless I have to (3.5mm to 1/4 inch, juicedlink is 3.5mm). I just tried it though and the levels were much better with much less noise. This is very mystifying to me. The mic 2 input, in the manual, is made more for direct in dynamic mics...I'm not sure why the Juicedlink works better on this input.

Also, you mentioned interfacing with a camcorder. I'm not doing this, I'm running dual system with a DSLR and syncing in post.

The Juiced link product was DESIGNED to feed a mic-level input. The manual attempts to make this not so mystifying.


...Also, you mentioned interfacing with a camcorder.

No, I did not mention that. That was part of the quote from the manufacturer's user manual for the gadget. It was designed for the kinds of applications where you have no choice but the input to a relatively low-grade mic input (like recording on DSLR or camcorder). In that kind of situation, it is probably a great performing product. But you don't seem to be using that kind of application. You seem to be needing a more conventional mixer with the traditional options of mic-level and line-level outputs to feed various downstream equipment.

Probably because as you stated that input is designed for a dynamic mic which typically is less sensitive than a condenser mic. It would seem that its sensitivity matches the output of your microphone a bit closer than the other input. Maybe your Azden mic is not putting out the level that it should?? I looked at the specs and it is more sensitive than a typical dynamic mic so maybe try a different condenser mic and see what happens.

Also the cx211 does not provide Phantom power. Does your mic need phantom? You should have got the 300.00 JL with phantom. When you run mics on batteries their sensitivity decreases too.
 
I wondered about the output of the mic, but there's not really much I can do other than replacing the batteries. The mic doesn't work on phantom power. It has an on/off switch and is powered by one AAA battery. That's why I didn't get the JL with phantom power, and it was $120 more.

Have you contacted JuicedLink about this? I re read your post and it sounds like there are two issues. Clipping and the lower levels. You said you liked it at first. What changed? I would get on the phone and talk directly to them with everything plugged in. Perhaps there is something that has gone wrong with the unit since you bought it.

I might do that, Bernie. Oddly enough the first time I tried the mic2 input the other night, it started getting noisy randomly. It was very strange because it wasn't interference...but just sounded like a higher signal-to-noise ratio. I moved the xlr around a bit as it was seated in input1 on the juicedlink and the noise cut in and out. This lead me to believe there was some sort of short in input 1 so I tried it in input 2 and didnt have the problem...I then tried it again in input 1 and couldn't repro the issue. Very strange.
 
Could havbe been some dust in there. Try blowing it out with some compressed air and see if you can make it happen again.
