Topic: CA11 & STC-9000 : Some questions and tips

[Church-Audio]

Cool, Chris. Will you be offering a trade-in for those of us with the old 9k?

I  might.

What does the HPF do on the CA9000?  I've had it on for my  two recordings but was curious as to what difference it makes in a recording.

If it's the same as the ST-9100's, which it probably is, it starts to roll off the bass below 100 HZ. If using cardiods mics always leave it off. There are times it can help with omnis,which pick up more bass than cards, but I would usually leave it off with those as well and reduce the bass in post, if necessary. Chris says you can use it with omnis to reduce wind noise or at loud rock concerts with excessive bass in the mix.

I haven't recorded with my CA-11 > STC-9000 > R-09 rig in a while and used it last night at an outdoor show (my son took the Avantone CK-1 > Fostex FR-2LE rig to Bonnaroo) and I have forgotten what the "unity gain" was on the R-09. I thought it was 15 or 16 and I think I ran it at 16. I was about 30' from the stage, DFC/FOB. It was fairly loud, but to get decent levels without adjusting the input on the R-09, I had to switch the STC-9000 gain to +30. At +10 it just looked too low.

The recordings sound fine, but should I have switched the STC-9000 to +10 and just raised the input on the R-09 until I got levels I liked or just kept the R-09 at 16 (which might NOT even be unity gain) and boosted the set in Wavelab?

Still happy this little rig will get nice recordings when I need it.

I use the same setup, except I have the CA-9100 pre.

What I'm about to say doesn't speak directly to your post, but I still think it's worth adding.

After a few recordings of mine turned out to be recorded at a volume level that was much lower than what I wanted - lately, I've been recording everything in 24bit.  I just recorded a show a few days ago.  I had to boost in 19DBs to get it where I wanted it.  Since it was recorded in 24bit, there was no hiss or other anomalies (that I could hear), even though I increased the volume as many DBs as I did.

I have a couple of 16GB SD cards - so space is never a problem.  I'm going to continue recording in 24bit so that I can "recover" more easily when I don't record at the correct volume.

What are some good rechargeable batteries/chargers to go with a CA9000?  I was looking at the Maha/Powerex 9.6v, but i'm not sure which charger would be best to go with it. 

[fmaderjr]

Google is your friend.

Per Thomas Distributing:
We strongly recommend the use of the New MAHA POWEREX 10 CHANNEL COMMERCIAL 9V FAST / SMART CHARGER - MH-C1090F or the NEW MH-C490F 4 Cell 9V model. Other chargers will not bring this 9.6V to full voltage unless they have a charging output voltage of at least 10 .5 volts while charging ( under load ) and may shorten the rechargeable batteries useful life.

Hello to all!

I have the ca-11 cardioids and the preamp ca-9000.
In the edirol r09hr it's better to use the "line in" plug?

Generally, yes.

If you haven't already done so, put on a pot of coffee and read the Edirol thread (all four sections).

For quiet stuff run mic-in on the R09

I just got an STC-9000 in a trade.

I haven't recorded with it yet so I can't say for sure, but I don't hear any change in levels when twisting that knob in the middle of the top. Mine has a +10 - 0 - +30 switch. So, the "volume" knob just turns it on, is that right?

No the volume knob is a VOLUME and reduces to almost off to full output. There is no way its not working because if its not working that means its ether bypassed or its not in the circuit. And I dont build them bypassed or not in the circuit

OK, cool. Thanks for the info Chris. I only tested it by sticking a pair of cheap headphones into the output with the mics plugged in. It sounds like I need to always run that knob wide open (fully clockwise), is that right? So after it clicks ON I just turn it all the way up and I'm good.
