Topic: Edirol R09hr freezing while recording/loosing one channel

[Lonman]

Looking for information about R09hr freezing 30 minutes into taping. It then would not turn off with power button and had to pull batteries out to dc it. prior to the freeze one channel had distorted imput signal and then flatlined. It was a generic sd card 8 g class 2. Three things I question 1) card not fast enough to capture the  24bit 48hz     2) had preamp with R09 on my lap under a coat and got real warm but not hot. Too hot maybe?   3) pre amp ran low on juice and could only supply enough power to one channel or would both channel signals diminish equally if it was short on power.  After the show went home an tested and everything worked fine.  Has anyone had problems with anything that sounds like this ?  I am using a new CA9200 pre and had it on 30db and edirol imput on 48. Have not had this problem with class 4 or 6 sd cards so I think maybe class 2 card problem or over heating rig. It was hot in the venue and rig very warm on my lap...so?
thanks for any help.

I bet its because it dropped too much voltage/current

What did this include? After you took the batteries out of the recorder and put them back in were you able to start a new recording with the preamp using the same batteries that were in both? Or did you put different batteries in one or both? And did you switch to a different SD for testing?

Is this the first time you used the SD card you were using on that recording?

If the battery on the preamp got low enough or died I can understand one channel getting distorted and I guess depending on design maybe one channel would go away, but not sure why that would cause the recorder to "freeze". That seems more like a SD card issue. Class 2 shouldn't be an issue as I use them all the time, but maybe the brand of class 2 might be an issue.

Drop in voltage meaning 9volt battery in pre was weak? The recorder batteries were new Lithium plus and new. There is no battery choice for lithuim so I chose alkaline in the R09 menu but I don't think that will affect any negative performance of the unit. I used the same recorder and pre 2 nights before with no issue but had a class 4 Sandisk ultra 4 g card in the recorder for that. I know that once I had a similar problem with the sony M10 using rechargeable 9volt in the same pre and I lost one channel and could not max the db on the pre due to lack of juice but that makes sense since 9 v rechargeables are ? compared to alkaline 9v.

SD card was sandisk 8g and thought I used it before but maybe for 16 bit 44.1 hz and not 24/48 I don't remember.

I appreciate the thoughts and any new ones. Maybe I will record my stereo for a couple hour with fresh batteries and see if I can repeat the problem.

So maybe 2 problems: card not good (freezing) and battery spent in pre enough to drop voltage needed?
