André Boisvert Posted October 10, 2008 Report Share Posted October 10, 2008 Like the title says, I'd like to power my Edirol R-09 (3V) off my 12 V bag supply. I can handle the solder side, I just need a bit of help on the down convert part. Overall, I like the R-09, but my biggest beef is with its 2 stage door. First stage to access the SD/USB, second stage to access the batteries. Dumb design; it's going to be the first thing to break. So, if I don't have to go for a battery change, I think it'll last longer. Thanks. Quote Link to comment Share on other sites More sharing options...
jason porter Posted October 10, 2008 Report Share Posted October 10, 2008 Hi Andre, I can't help you much but I can recommend running it on NIMH's (2500mah) I get at least a full day of recording (start and stop) from 1 set. I thought about the external power option, but the DC connector isn't very robust. -Jason Quote Link to comment Share on other sites More sharing options...
Audio Daddyo Posted October 10, 2008 Report Share Posted October 10, 2008 Hi Andre, A switching regulator should do the trick. I bought the 5 volt version but here is a link to a 3 volt switching regulator. http://www.dimensionengineering.com/DE-SW033.htm I used it to power my Marantz PMD620 off my Lithium NP1 and it works great and it's only $15.

Andy Perfect Andy! Exactly what I was looking for. Jason - I'm currently using Powerex 2300mAh and I change at least once a day. Maybe they're getting old. Thanks.

Philip Perkins Posted October 10, 2008 Report Share Posted October 10, 2008 Before you clip leads or solder the convertor, try it out with some alligator-clip leads on your rig. Some of those types of convertors make a lot of RF, and it will be in close proximity to your wireless RX. I had a big problem with this a few years ago and ended up having to switch out convertors because of it. Philip Perkins Quote Link to comment Share on other sites More sharing options...

I had a big problem with this a few years ago and ended up having to switch out convertors because of it. I've heard about the potential RF problem before so it is not a bad idea to check out the switching regulator first using alligator clips. In my case I have Lectro 411s in my bag and have no RF problem with the switching regulator I recommended to you. Andy Quote Link to comment Share on other sites More sharing options...
André Boisvert Posted October 23, 2008 Author Report Share Posted October 23, 2008 Update. My Edirol is now powered off the bag and workin' fine. Thanks Philip, for the heads up on a potential RF problem but, as in Andy's case, I'm seeing no new RF. What did surprise me was what the Edirol puts out (a test I hadn't done before). 90% of the 1st horizontal line while scanning my 411's (blk 25 & 26) is black and about 70% of the 2nd. Without it, I'm probably 10% of the 1st, 5% of the second. I was under the impression that most of the garbage RF from NL recorders came from the HD. For the short range I usually need, it hasn't been a problem. Since I no longer saw a use for the AC supply, I used the 90 degree DC plug with 2 feet of cable from it. It made for a quick'n easy job. Thanks again for the link, Andy. Quote Link to comment Share on other sites More sharing options...
Audio Daddyo Posted October 31, 2008 Report Share Posted October 31, 2008 Hi Andre, Glad that the switching regulator worked out. I will have to check if my Marantz is getting into my 411s blocks 21 and 26. I never thought to check that out. Thanks, Andy Quote Link to comment Share on other sites More sharing options...

Thanks again for the link, Andy. The HD is certainly a big factor, but I still get plenty 'o RF from a 702T (CF only) and an H2 (SD only.)
