Rolls PB224

["Debbi B" dgbrusco]

It seems like the 9v batteries in my power supply (used with Rode
NT-1A) don't last very long. I used it to record maybe half an hour
worth of actual recording, not including on pause, which was probably
30-60 minutes if that. Previous to this either I've forgotten to turn
off the power supply or the switch got turned on in my bag. This time
I made sure to turn it off.

Is this within the normal range one would expect batteries to last?

(Of course, just when I want to use it, I don't have any extra
batteries. The neighborhood Mockingbird has been including "meow"s in
its repertoire.)
