Topic: Best external power for an R4

[salmonite]

Hey there,

I am new to the board and have just recieved an R4. I am wondering what would be the best option to power the r4 externally. I'm not very knowledgeable about external power, as I have just been running an AD-20 into a minidisc for the last year or so and have finally upgraded my rig. Any help would be greatly appreciated. Thanks.

I've been using these...

I get plenty of time running 4 mics with phantom power at 24/96. I've never had any problems. if you look around you may be able to find them cheaper. I got mine for $49.

Thanks for the help. I have been reading some of the posts on the R4, and am a little confused with the polarity issue. Will I need to reverse the polarity with a pack like this?

Run a search for UA-5 power options. Lots of us use Lithium Ion portable DVD player batteries, but there are many solutions. The battery/cables are the same for the R-4. You'll find plenty of info on the polarity as well.

well the these particular units come with some "plug-n-play" components that allow you to build your own cable. Basically it is a cable with various tips that plug in to accomodate various different sizes of inputs. all you need to do is put the tip on backwards and it reverses the polarity.... I may be saying that incorrectly but I assure that it will work with the factory parts.

I will see what I can come up with. Thanks for all the help, this place is great.

I think I am going to go with the PR2310, I found one for 30 bucks, so it seems like the way to go. Also, does anyone know where I may find custom mic cases, or at least hard case shells? If need be I can take this question to a different place on the board, but thought i would start here. Thanks again for the help.

You'll get more responses in the Mics & Setup forum.

where did you get one for $30? I may pick up another just so I have enough juice to run all day and night at festivals.

I should mention... be careful when ordering these batteries there are a variety of models that all look the same, but don't provide the same amount of power. One company sent me the wrong model and I didn't figure it out until I had them for a few weeks. the lower models will not even be enough power to get you through an entire show... believe me I learned the hard way.

Sorry for joining late but here's one more vote for the Walmart DVD batteries.  Work like a charm for me.


side note: I noticed in the R4 Pro manual that you can now select the voltage of external packs.  Pretty cool.

I found it on laptopsforless.com, and it looks to be the 2200 model. Is there a serious difference between the 2200 and 2310?

Yes.  2200 will offer less than half the run-time of the 2310.  See below.

Okay, I will have to cancel that order. No wonder it was so cheap. Thanks again for all the help, and quick responses.

Hey shawn,

Where did you find yours for 49$? Most that I can find are in the 80-100$ region.

I got mine at laptops for less, but they quit carrying the 2310.
