Korg MR-1
« on: March 03, 2007, 01:29:48 PM »
NEW TREAD FOR MR-1

In reply to Jeff's message regarding external power:

http://cgi.ebay.co.uk/Qtek-9100-High-Capacity-External-Battery-5400-mAh_W0QQitemZ160077305401QQihZ006QQcategoryZ48674QQrdZ1QQssPageNameZWD1VQQcmdZViewItem

I got the above (just under $100)...works great. Will take my recorder out tomorrow Sunday for my first stealth recording (with DPA 4052 and MixPre). Will let you know how it goes.

Be nice if someone with an MR-1 could record some silence at a few gain settings (no mics and possibly with load resistors) so we can do some analysis and get an idea what the noise floor looks like..


Should be able to measure the internal noise floor with just the unit alone...so room noise won't be an issue.

Maybe I need to read the post I quote better before I respond.  Didn't see the part where freelunch said "no mics and possible with load resistors"

also, if someone wants to open theirs up, I'd love to see how the battery and HD are positioned inside the unit.

I'm on the fence about ordering one, if it looks like I can swap out the HD for a CF card and a bigger battery, I'll go for it.

some eye candy, and a benchmark for size.




about 1/3rd thinner, but large footprint overall than the R9.  Its pretty..thats for sure.
nice case that comes w/it too.  I fired it up on AC power quickly, and it boots super fast, and is ready to roll.  meeters were HUGE, like DAP-1 sized (taller, but not as long...though close).  Super easy to see, thats for sure.  I'll be doing all sorts of stuff w/this in the coming week.

I'm running an external battery test right now, line in with zero added gain at DSD resolution (what's the practical difference between the three DSD formats they let you choose, but don't talk about at all?).  SO far it's gone 3 3/4 hours with the guage on the Powerstick 15 (a BatteryGeek Lithium Ion adjustable voltage battery/small flashlight) showing about 1/2 charge still remaining in the Powerstick and full battery in the MR-1.  The Powerstick is about the same height and thickness as the MR-1, about 1/2 as wide, weighs a little over 6 oz.  It is rated at 4000mAh (but I think you have to run it at 3.7V to get that, it is 14.8 Wh rated, which would be about 3000 mAh at 5V).  This looks viable.

I used it last night with external power - this thing...
http://cgi.ebay.com/O2-XDA-Exec-High-Capacity-External-Battery-5400-mAh_W0QQitemZ150097200098QQihZ005QQcategoryZ48674QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

It lasted for about 7 hrs (plus charging the internal to full capacity) and still going - maybe still have about 10% of the external left with the internal charged up and un-tounched. Maybe it will last 9 or so hours in total...don't think it can run the MR-1 longer than 10 hrs (even though I calculated it to be 12 hrs :( ).

Anyone know how to change the file size? I think it was preset to 1GB...Cannot find the info in the manual how to reset it to 2GB file size. It auto cut my file every 22mins recording at 1bit DFF.

Anyone tryed to make a CD of their recording yet?

The Audio Gate program is just for simple editing nothing complex.

How are you plugging in the external battery?  Are you using the USB or where the power plug, plugs in?

There is a cable that has the USB one end and the power connector on the other end. I got the retractable mini right angle one.

Like this (similar):

But the power end is RA - good for stealthing.

What kind of time do you get without the external pack, ie just running the internals...
Thanks for your time in this....John

Today I tried recording at 1bit and the internal battery lasted for about 2 hr 30 mins after a full charge.

I ended up getting about 5 hours from the small external battery and then about 2.5 hours on internal, but it shuts down and needs to be restarted after 6 hours, as advertised.  This seems weird, as at that point I had 14 or 15 1GB files and it shut in the middle of another file at the six hour mark.  What is the reason for this six hour limit (which seems to apply no matter what resolution you are recording at)?  Can it be defeated?  I think it parses DSD into 1 GB because if you convert to PCM 192/24 you will get 2 GB and if you divide your DSD files at 2GB you might exceed the Windows file limit in high resolution PCM.  Has anyone yet tried joining the bits together?  The manual is a little worrisomely unclear about whether you'll get a seamless join.

How is the software that ships with it?  As Jeff mentioned, re-join and also 1-bit to pcm conversion..


I haven't figured the software out yet.  All I can seem to do is resample files.  Can you edit with the software?
Also, I'd like to know how to change the file size limit as mentioned earlier.  Anyone figure that out yet?

Ok, going on about power consumption is fine, but what does this thing *SOUND* like? Isn't that still the most important criteria here?
Have any of you MR1 owners listened back to a recording yet, even just a recording of you near the computer or something, to judge the MIC preamp noise level?
