Re: Korg MR1 - Battery replace

Well, I'm wrapping up the summer taping using two R44s again. Plus some whacky stuff to use 2 digital preamps, and I have to point out that the Achilles Heel of the R44 is the double volume knob that adjusts only in increments of 6 db. The korg MR1's individual inputs are fantastic and the unit is so light! I really think all the fuss about putting in a bigger hard drive was a mistake and it's putting in a better battery that we should have been looking into.

Has anyone had any luck finding a battery store that refurbishes lithium batteries?
Can that even be done?
How long should lithium batteries last?
this is definitely not normal

to reanimate the old thread:

I use two MR1s since 2010 sooften I'm too lazy for equipment, and did meantime loads of takes after the mtron ssd mod (runs totally quiet and reliable) and after a simply exchange of batteries. batteries for me aren't that problem of the machine, using everytime external solutions, mostly a 4x18650 2A powerbank into the dc in. lasts endless, in 7 years never reached to empty it on a workers day. For intern rugged solutions the space is too narrow. Look to fix together reliably the MR1 and the powerbank, may be with gaffa.

Till today the MR1 in terms of a/d conversion seems finest small machine under the Zax and Sax class. And two 3,5mm jacks balanced mono line ins are very delicate and unique, though the small machine isn't made to stay rugged outdoors in sun, rain and snow.

I confered MR1 takes sometimes with a good studio converter and can say, it's hearable quality going 1bit with later pc conversion to pcm wav is smooth enough and useable. The machine was badmouthed some years ago with irrelevant arguments may be to save the concurrencies courage.

An important weak point and price minimizer is the smallish cursor wheel, made for clean and tender ladies thumbs. From time to time will need --  no, I'll conceal.

Think the MR1 will give future years fine takes in commodius and lazy situations, if good preamps are nearby. Small machines with professional preamps now run the sound recording way. MR1 with SD 302 frontend doubles the weight of a SD Mixpre3. In 2010 it was a challenge, nowadays perfectly well responded, shurely not a last step minimizing size of great sound quality. Only the physical need for not less than 1/2 inch microphone capsules and xlr ins will stop that.

Okay.


Well thanks for keeping this thread going!
I was looking into battery solutions, because I want to be able to carry 3 or 4 MR1s, each with their own preamp. For 1 I use a tinybox, so that's about the same size as the MR1, then add the Korg 4AA powering pack, and that's 3 things all wired together bigger than my fist. But that's the smallest I've ever been able to make it. If I could just trust the internal battery for 2.5 hours, then that would help a bit, but I've given up on that now. The trick is to just never let it die completely! (I guess)

What I'm looking for now is a clean preamp to the dpa4021 mics with their giant XLR connectors powered at p48 and into the MR1.

Eventually an external battery will come along that lets me plug in all 4 MR1 units and get the 2.4amps out from each, ideally it would be about the size of a DVD battery.

Right now I use this:

https://www.amazon.com/Tera-Grand-7800mAh-Digital-Display/dp/B00F02UKYE/ref=sr_1_8?s=electronics&ie=UTF8&qid=1400700628&sr=1-8&keywords=lithium+5v+2+a+output

which gets me only one 5v 2a output, but it does the job pretty well.

Anyway.

this is definitely not normal

oh, look! 2 of these might do the trick!
