I’m interested in the CA 9000 Preamp or the 9100 and I have a few questions.
I want to record some local live bands and Drag Racing events. In the past my old Sony minidv’s where able to handle these situations.
The TM700 has a mic level adjustment -30 to +6. I’m able turn on and off AGC. I tried AGC during a band record and it just clipped the best parts.
The Mic level adjustments must be done while not recording.
My setup
CA 9000 Preamp
Panasonic TM700
Rode Videomic Pro
Will the 9000 allow adjusting the level on the fly?
I can’t tell from the pictures what adjustments it does have.
Any recommendations on cabling?
I understand the 9100 you can order with 3.5 in? Is there still a left/ right or 1 stereo jack? Looking for one jack I would think?
Would I run it like this allow for capturing the sound without muffling it?
Rode set to 0DB to the 9000 (what settings?) to TM700 set to 0DB or -6 or more
I'm also thinking of getting the CA 11. I don't see the CA 14's ..are they still for sale?
Thanks!

The STC-9000 has a switch for +10 or +30 gain, a output control knob, and a high pass filter switch(in the batt compartment). the output can be adjusted during recording, just had to do that yesterday where I had it too loud for an onstage recording. cabling should be 1/8" miniplug > whatever input your recorder has.
I can't vouch for your recorders ability to handle the signal but you are on the right track with the STC-9000. I used to record CA-11s > STC-9000 > JB3 and the STC was really the strong point of the rig because the JB3 recorded at low levels and had terrible level meters. Now I use CA-14s > 9000 > Tascam DR-05 or DR-07. the tascam units are great for their prices, i would recommend looking into one. i dont believe any MD recorders can do 24 bit, which can be necessary in post if the levels are too low.

You are going into a mic input on the camera I would suggest the + 10 setting on the 9000 and reducing the level from the output level knob on the preamp to 70% then trying the camera with the AGC off. SLOWLY increase level on the camera until you have undistorted audio monitor with headphones.

Dang, that's a nice camera you've got. :)
It's been my experience that you need about 27 dB less signal for Sony videocameras than what you need for the input to a typical line input to an audio recorder. I would expect Panasonic's mic inputs to their video cameras to be approximately the same. If your camera has a -30 dB input attenuation setting, that seems to indicate that they've already accounted for the difference for you. On mine (a Sony), there is no such input attenuator, so I built my own cable with an attenuated output for direct connection to the mic input of the camera.

I'm going to piggy back off of this thread since the title I had in mind is the same.
A friend recently got some CA-11 (with omni and card caps), the STC-9000, and an Edirol09. I have the same rig, except for the 9000 -- I have the 9100. I am trying to help my friend out.
Here's the question: what are good settings for the 9000 for a moderately (average) loud rock show that a person is stealthing with the mics clipped to glasses from fairly close to the stage? I'm especially curious about that lever.
Thanks!

I would go + 10 db max volume on the knob. And then adjust the gain on your recorder to taste.

Chris ~ what about the position of the lever (the silver switch). As viewed in this picture - would it be down, in the middle, or up?

Hi,
I have the same preamp.....I use the lever switched over ) from what you show so the pre has low gain...ie for louder shows.
Also I have the gain set at about 85% max and adjust the recorder to suit.( running sp-cmc-8 cards into R-09 ) AND set the R-09 to level 13-14 AND use LINE IN
This will give you ecxellent results if you stand FOB or in the swwet spot near the speakers
Hope it helps and good luck
( I really like my STC-9100 Preamp from CHRIS ! )

Let us know how it works out and what you ended up choosing :)

It's been a while since I owned my 9000. But if I recall correctly, you should always run the knob at 100% when recording an audio show. By moving the knob you are just changing the volume out of the preamp. The recorder will still see the full effects of the gain. The knob is NOT a trim or variable pot. I found this out the hard way and ended up with a show that looked like a stick of butter. Even though I wasn't clipping on the recorder meter, coming out of the recorder I was clipping and didn't know it until I loaded it into my editing software.

I think it's the preamp that sees the full effect of the gain. I think you overloaded the 9000. The 9000 should be set at +10 Db for a loud show. Setting it to +30 could cause the 9000 to overload. Use the + 30 Db setting for acoustic and other relatively quiet stuff. And you do want to keep the volume control set to the max.
