Hi all!
I've just got myself new CA-9200 and have this problem. Found this thread
http://taperssection.com/index.php?topic=144168.msg1857429#msg1857429 , but it doesn't help. Lets listen to the samples. I played few notes on harmonica, so you can feel how high the level actually is. Almost the same level on all three samples.
1) CA-14 cards -> CA-9200 (+40db, volume to MAX, HPF off) -> CA cable -> sony m10 (line in)
I can hear local FM station and some noise same to the cell phone interference. Before the test I turned off all radio devices at my flat. When recording on lower levels, radio is still pretty noticable.
2) CA-14 cards -> CA ugly bbox (with fresh GP battery) -> sony m10 (mic in, high sens., level at max - 10)
There is something like wind noise in right ear. May it be because of cheap chinese battery?
3) CA-14 cards -> sony m10 (mic in, high sens., level at max - 10, plug in power ON)
Everything seems to be allright. At the end I hear some radio, but it's very low.
I've tried different mics (CA-14 omnis), different cable... Nothing helps. Even with [mics->9200->headphones] everithing is the same. Turning HPF on doesn't help either. I thought about sometimes using 9200 for home recording at high gain (well, for taping loud shows too), but for now it doesn't look like an upgrade. With this damn radio noise... Maybe I will not have these issues at a venue? I tried to take a walk on a street with gear in pocket - same.
Any ideas, guys? I would appreciate any help.
