Church Audio CA9200 - levels question
« on: March 07, 2014, 06:46:09 PM »
On Thursday night, I used my new Church Audio gear for the first time. Rig is CA14 cards > CA9200 (just switched on as no extra input needed as it was loud) > Edirol HR-09). Was taping about 10' from the stack and was pretty pleased with the results. However, one thing concerns me:

I was taping in stealth mode and due to a roving security guard, who may or not have busted me if seen, when I needed to make a quick level adjustment on the fly, I just turned down output on the preamp, rather than pulling out my recorder. Anyone else done this who could comment on results? Might be a daft newbie question, but which would give a better recording and crucially, by turning down the output, is this going to have an adverse impact on my recordings?

Any swiftish advice gratefully received as I am taping again on Monday.

The Edirol/Roland HR-09 is similar to other inexpensive recorders in that it has a crappy preamp, which is why you bought the Church Audio preamp in the first place. You want the recorder in "line" mode, bypassing the internal preamp. In the case, plug the preamp output into the Edirol line jack, then adjust the recorder levels with the Church preamp.

Yes, this is how I've done it. Run the Edirol at unity, line in and deal with the levels on the Church Audio preamp.  never a problem with the results.

That's what you're supposed to do. No issues as long as the recorder is set to the approximate Unity Gain (38-40 on the HR). If you set the recorder way below unity gain, you might have to bring up the levels on the CA9200 so much to get good levels on the recorder that the CA9200 itself could clip (and if you're not monitoring with headphones you'd never know it until you listen to the recording).

Even if there's no audible difference when you it this way, as you said changing the levels with the CA9200 is quicker & more convenient. Also if your recorder records some brief static like noises while changing the levels (and many do) you can avoid this by changing the levels with the CA9200.

I have accidentally moved my m10s gain to 10(max) and didn't notice it til AFTER the show, which meant I ran levels LOW on the preamp, and it turned out just as good as running the m10 at unity(4-6)! But that's with an m10 not an r9

Thanks for the advice guys. Pretty much backed up what I thought.

I did use the mics again just over a week ago in Birmingham for Camel. Was not directly in front of the stack and found even just above Unity Gain was insufficient - very quiet PA. I cranked it up full on the preamp, but was still barely registering levels and had to boost the recorder level towards 60, I believe it was. Half a dozen static clicks as I did it, but I was very pleased with the recording overall. Maybe I could have set the preamp at +10db, but it might have been too much. Am planning on using my CA11 omnis tomorrow for an acoustic gig, so will use it as aproper preamp then. Here's hoping they are as good as my CA14s, which have really impressed me so far.


BTW, does anyone know roughly how many hours you get out of the battery on a CA9200? I know it depends how much gain you use, but a ball park figure???

I think Chris said it was a little over 50 but it may be even more for battery life that is

Thanks, Phil Zone.
What they said :) Yes you pretty much all the time want to go with the line input. Unless you are recording something acoustic and you can in these cases go mic in but you have to be very careful.

Hi! So in the case of a Zoom H4n, if I use the mic in jack I will be using the internal zoom pre-amp instead of the CA9200? In this case, should I use one of the bottom, line 1 or line 2 polyvalent jacks (for XLR4 and others)?

The battery is supposed to last anything around 50hrs?

And lastly, last time I used mine, I noticed a huge difference in left and right recording levels (using CA11 mics, through the pre-amp through the mic in from the zoom). The other times I did it, the levels were equal for left and right. Any troubleshooting I should think about? Thanks in advance...

Guys w/ 9200 where are you typically setting your gain & volume on the preamp just about "cranked"?

I have accidentally moved my m10s gain to 10(max) and didn't notice it til AFTER the show, which meant I ran levels LOW on the preamp, and it turned out just as good as running the m10 at unity(4-6)! But that's with an m10 not an r9

volume on the pre all the way. gain 0-15 for "loud" stuff and higher (30) for quite/acoustic stuff.  first time out with it I ran onstage omni's and levels where very low on the m10. I then cranked the pre all the way and while the levels looked good I got brick walling.

:medal to the above ^, this is the insight I am looking for.......do you all consider Widespread Panic & Umphreys "loud?"

Silly m10 question LFC on or off & what mic sensitivity setting?

M10 lcf is too steep,200hz @24db per octave,leave that off and sensitivity always Low.
