Wholesome - thanks for the info.

I think I'll definately need a proper fluffy windscreen at some point, not just foam, so I emailed this guy who's all over ebay selling windscreens specialised for each of the portable recorders. He says they should easily be able to make one for me, though I'm not sure whether he realises it's got the little T-mic and not something built in... Here he is btw http://myworld.ebay.co.uk/hearley/
Depends if I get a new mic for it of course! Need to find some opinions on the quality of the supplied mic...

You say I'd need a battery box to record loud shows - why is this? Seems counter-intuitive to me, in my ignorance, I'd have thought you were more likely to need extra power for quieter stuff? I assume the problem is not enough juice coming from the plugin power? How can I work out/find out if a mic will run ok without a battery box?

The t-mic with the unit has omni mics...much less susceptible to wind noise...may not be needed with the existing windscreens.  I can't say that I've heard anything great about the mic.  I imagine it doesn't give very good results.

The louder the music, the higher the sound pressure level and need for more power than plugin power offers.  Any standard electret mic is gonna need a batt box or preamp supplying 9v to prevent distortion.  I believe that having a 2.7k mod done, you can run fine off plugin.

MT2 arrived today and is currently charging!  Unfortunately, my amazon order with my kingston cf card didn't show up as scheduled, so I'm going to have to wait until tomorrow to do any testing with it.  First field test will be Friday for Will Hoge.

first impressions..awfully light.  I can see how some would be put off by it feeling "cheap".  menu is responsive enough..I remember reading (maybe about the MT1) that the menu was pretty sluggish but this seems just fine.  Updated the firmware to 1.0.7 with ease.  Battery life is looking pretty rough.  I charged this for about 7 1/2 hours out of the box.  Limited with a 512mb cf until tomorrow, but I've recorded about 50 minutes of 16/44 wav with the included mic and updated the firmware...and I'm at half full on the battery meter.  Yikes.  I was planning on getting external power anyway, but I'm now definitely going to make it a point to get this in time for my first show with it on Friday.

I have found that the power meter goes down fast and then slows down after 1/2 of the meter is gone.

hopefully a few cycles will get it in shape.  It's down to about 1/4 now with roughly 100 minutes recorded.  I suppose any usb powerpack will work?  I'm going to have to pick up something locally to have it for friday.

This is good to know, makes sense!

I can't say that I've heard anything great about the mic.  I imagine it doesn't give very good results.

One would assume so, though I definately recall at least one instance of a Microtrack owner on some forum somewhere being surprised at how acceptable it was... The only answer to this clearly is to try it out myself! Did I mention, I ordered mine the other day? So I too shall post my findings once I actually possess one.

The louder the music, the higher the sound pressure level and need for more power than plugin power offers.  Any standard electret mic is gonna need a batt box or preamp supplying 9v to prevent distortion.  I believe that having a 2.7k mod done, you can run fine off plugin.

Interesting stuff. 2.7k mod, is this a resistor or capacitor? On the PCB or somewhere easier to work on? I'm intrigued.

Aye, aye, I've heard repeatedly that rechargeable batteries take time to maximise their potential, to wear in, sort of... In fact, let me find that article I was reading...

Here we go! this page: http://www.sonicstudios.com/batsys98.htm is a ridiculously deep discussion of that ever-enthralling topic of: Batteries! It's quite marvellous. I think this is the page of a taperssection user isn't it? Guysonic? If I'm right, well done that man. Very important passage towards the end concerning lithium ion batteries (the kind in the Microtrack, and in many external batteries, like this one I've bought http://www.superetrader.co.uk/u2o-iup-5400-universal-external-battery-black-pda-mp3-p-3684.html):

"Suggestion: For longest service life, store all lithium battery packs and decks with internal lithium batteries with battery at <50% remaining capacity. Recent article states that capacity loss in storage is greatly reduced with NOT storing these at full or near full charge.

Yearly loss of storage capacity with always fully charge cells is as much as 30-40% per year of storage. Batteries stored at <40% charge loose much less capacity (<4-8% per year) while stored.

So best case for Lithium Ion battery is being used down to 30-40% remaining capacity, and stored in this condition until needed, and then fully recharged just before using. Used in this manner, cell life to 80% capacity may extend to as much as 5 years."

Can't say I'm looking forward to constantly worrying about the state both my batteries are in while being stored, and trying to recharge them just BEFORE use. Could be rather frustrating, couldn't it?

oh well  ::)

fwiw, I ended up getting about 3 hr 20 min on my first test with it.  Definitely going to be running external usb power for any but the shortest outings.  Otherwise, I like what I see.  I'm going to do more testing tonight with the full rig and running 24/48 digitally from the ua-5.

edit: picked this up at rat shack.  $40 for 2100mah is a bit more than I wanted to spend compared to online prices, but I wanted the piece of mind of having it tomorrow at the show.  I don't do festies so this one should more than suit my needs.  should come in handy for charging my iphone if i'm out and about away from power too.

love the form factor.  nearly identical to the MT2 LxW and about 1/4" thick.

I have just a AA battery enclosure right now, I think I should step up to something like this for the MTII.  What kind of tips did yours come with?  You could use this to charge your iriver h320 too if you have it Rockboxed, not that you really need to charge the iriver's given their battery life capacity for a single show, but you could.

first recording went by fine last night, no gremlins.  One question I have though..when the usb battery pack is connected..should it show as charging for the entire show?  I assumed it would act just like it's plugged into the wall, with the check mark and plug icon over the battery.  MT was fully charged before going out.

What kind of tips did yours come with?

If you're curious about the U20 I-up thing I got, it came with: mains supply for charging the thing itself, USB->thing i don't recognise,but i guess is ipod, USB->female connection which in turn connects all the rest of the tips: all sizes of round tips, including one that looks like it would fit nokia phones, a small flat thing that looks like a wider USB mini, and even a sony ericsson phone connection.

should it show as charging for the entire show?  I assumed it would act just like it's plugged into the wall, with the check mark and plug icon over the battery.  MT was fully charged before going out. 

Weird weird weird, I'm still waiting for my CF card to arrive but I'll have to check this when I get mine set up...

I don't think the MT ever goes to the check box because you are using it at the same time you are charging it, at least that has been my experience.  I do recall, I think it was in one of the original MT 24/96 threads, that it is best to have the MT charged fully before going out so that the drain on the external battery is reduced.  The MT may get to very close to a full charge, but not quite all the way to switch over to the check box.  Congrats on the first run!

Just had one chance to play with it so far, very briefly. Only one thing comes to mind (using stock mic into 1/8" input):

LOOUUUD NOOOIIISSSES

loud hissing noise that is. hmm. near impossible to know how much is mic and how much preamp, til I can try a different mic... Anyone notice a significant amount of noise from the stock mic itself compared to other mics?

If I run mine long enough on external battery, it will go to a full charge. Usually during the second set.

Have never used the t-mic and am assuming that it pro'ly does offer up a lot of self noise.  Generally speaking though, the units internal pre is noisy.  Best running an external pre and running 1/4" line in.
