Topic: For JB3 Tapers:Problems you have had with your JB3 and what you did to fix them.

[Karl]

Good thread.  I have a few--

I've noticed, that when recording opti-in, if I leave it in pause for awhile, that the channels will swap when you unpause.  This is unverified by anyone but me right now, but I suspect it's a global problem.  I started a thread about it awhile back.  Thread here.

Rereading that thread reminded me that people have had issues with the meters swapping without the channels swapping.

Not really related to taping, but I've had problems when transferring mp3's to my jb3.  Notmad will act like it's transferred the file, but the file won't be there.  And then it does the same thing to any following mp3's--it will act like it's transferred the files in a fraction of a second, but nothing there.  According to Notmad's Omnitome, there are mp3 files that the jb3 has problems with, though it says you will get an error message (I got no error message).  In short, be aware that there are random mp3's that just won't transfer to your jb3.

Also, to support what bean said, I've had problems after formatting the jb3.  When you feel the need to reformat, be near your computer with the current firmware ready to go.  And make sure you power down/reboot a few times to make sure it's running smoother, maybe even do a test recording.

These aren't things to keep you from happily taping with your jb3, merely idiosyncracy's.

OK, so I just got this jb3. I transferred a show to it and then uploaded to my pc. I open it in CD Wave to track it out and I get the following message. Something like, " the header reports a different file size than the system, do you want to override the system size" either way, the file is truncated. Instead of 1:01:16, the time is reported as 10:16:01. Wavelab reports the same size and track length. On my JB3 the show is complete. So far I'm not real impressed with my JB3. You can have my dap1 when you pry it from my cold dead fingers. Any suggestions with the JB3 are apreciated.

Yeah - I get the same thing...but Soundforge doesnt complain about it...
I think if you just open and re-save it in an editor...it will fix the header...


are you trying to open it in a different sample rate from which it was recorded, by chance?
Nope, both at 44.1. I thought of that possibility. +T anyways.


This only occurs when you open it up fresh from the transfer...CD Wave is the only program I've seen complain about this...
Does anyone know what the correct response to the error message is? (accept, dont accept?)
Doesn't seem to matter which one you pick. I've tried both.
i agree with post's saying opening in SF first will fix the problem, and either choice of 'fix the header' or 'trust the header' gives the same result.  i also think if you upgrade the firmware on the JB3 this should stop this from happening again, not sure but i think it was just a bug w/ older firmware - i have 2 JB3s and only the older one has this 'problem'.  hope this helps.

I have firmware version 1.40.06. According to the faq it is proven to be stable. The wave file on my jb3 is corrupt. It reads 1:01:16 in total time, but will not play beyond 10:16; which is exactly the time that Wavelab reports.

Result: try opening and resaving w/an alternate wave editor. I haven't confirmed this myself, but will try it soon.----Kevin

Kevin Straker's post reminded me of another quirk of the JB3.

When you record optical in, you should have a digital signal being fed BEFORE you press record on the JB3.  Otherwise, the JB3 will default to a 44.1k mode.  What happens, is the header will be written as a 44.1, though the file will still be recorded at the proper sample rate (48k).  It's just a matter of rewriting the file header, but what a pain.

hmmm, another quirk here, i formatted the drive as usual before i go taping, and got the 'firmware problem' thing again

it WOULD NOT let me upgrade straight to version 1.40.06, so i luckily keep 1.32.02 and 1.40.06 on the comp all the time

i actualy downgraded from version 1.40.05 to 1 .32.02 AND THEN i had to upgrade to version 1.40.06

these can be tempermental like a dat but much more reliable IMO, just dont formatt unless you have a comp nearby w/ the firmware on it and not 10 minutes before you leave

JB3 1: Refurb

Known problems:

-Extremely heat sensitive. Wont start at all if exposed to even modest heat.

-Wont start if used for awhile...unplugged, and then quickly try to start it up again.
  Solution: Let it sit a bit...10 mins or so...usually powers back up.

-Battery won't charge. Won't run on a charged battery.

-Richmond Stockholm Syndrome show is laced with CD skip-like clicks...used analog in on JB3. Theories include Cell Phones or proximity to large 220 AC line...?

JB3 2: Bought used. This thing looks like it was used as a skateboard...

When it arrived - it would come on and hang on the EAX screen. I did a Reformat...that didn't help. Then I did a "Clean Up" and then another Reformat...and Bingo! - Booted just fine...has worked like a champ ever since! Not exactly the scientific method...but it works fine. No known problems.

using 1.32 on both...I tried to upgrade the refurb - JB3-1 - but it wants the battery to be in...which it cant...so it wouldnt work,,,

[Brian Skalinder]

Lest anyone think all JB3s have some or all of these problems:

I've encountered exactly exactly ZERO problems with my 3 JB3s (all refurbs, one each with heavy, moderate, and light use) other than those brought on by my own user error.

I'm not discounting the experiences people are relating in this thread, but I believe there are plenty of us out there who have had completely or nearly completely flawless experiences with the JB3.  Like any consumer electronic device, the JB3 has its quirks and experiences will vary - just as with DAT.

FWIW.

I've been getting a lot of cd like skips and pops on recordings happening too. They can be taken out later with audition without affecting the sound quality but it's pretty annoying. I even do clean ups and formats quite frequently and it still happens. I'm thinking it could be one of a few things happening:

a) my Jb3's disk is messed up
b) something is wrong with my optical cable
c) something is wrong with my UA-5 which I digi-modded myself

I've had some flawless recordings and some flawed.. I can't pinpoint what's going on. Any ideas?

[F.O.Bean]

agereed brian, when recording, ive had ZERO problems, it seems its only quirky when messing w/ reformatting/rescue mode

[F.O.Bean]

no offense bud, but i bet its either b or c

...carry a cell phone with you...? in or near your gear bag...?

[aberg]

No cell phone.. the gear bag was setup right by the soundboard and all that equipment... But I doubt that would cause any interference. I'm going to try using a different cable. I really hope it's not the UA-5.

best of luck bud!

My scroll-wheel sticks and jumps - how do I fix it?(thanks skalinder)

Apparently, this is a fairly common problem.  It just gets a little dirty, that's all.  Here's one user's tip on how to clean the scroll wheel:

I got a can of stuff from Radio Shack ... Contact/Control Cleaner & Lubricant worked wonders. I opened up my Nomad Jukebox 3. The cleaner is under great pressure so don't spray directly. Spray in a cup first and get some q-tips. With a Q-tip addes a few drops sparingly with a few quick blasts for a dust blaster. Did that several times, turning and pushing the wheel. I didn't wait very long to dry. The can's instructions say wait five minutes. A few blasts of dust blaster (air can) and I waited about 30-60 seconds, closed up everything and it works like new.
