I've discovered a "new" bug with the JB3. If you leave it in pause for awhile (I had mine paused for about 5 minutes, give or take) it will swap the channels after you come out of pause. I'm running a UA-5 into my JB3. I'm running firmware 1.40. It has happened multiple times. I realize that this is probably not a problem for many of you, since many of you have no need to stay paused for any amount of time. But I discovered it and thought I should pass it on. I know there have been reported issues of the meters showing the wrong channel, but no reported issue of the actual channels swapping. It's really not a big deal if it happens--you just swap the channels back in a wave editor and it's all good.
Happy taping!

if that's true, that's a big problem, imo.

Yeah, I thought I had noticed this too, but figured it was just me screwing something up...
It hasn't been too much of an issue however... Although I may go back and relisten to a show I got last week... That one sounded reversed I thought...

How are you connecting the UA5? (not sure if it is implied...)
Is this issue affecting the analog or line inputs...?
Sorry - I am unfamiliar with the UA5...
-
Ya, I had this happen to me @ a Ben Kweller show in April. Its really weird... On that note, does anyone know how to reverse the stereo in Cool Edit Pro?
-
I am connecting the JB3 to the UA-5 via optical cable.
Though unverified, I don't think it happens when using analog in. I used analog in enough in similar situations and never noticed a problem.
-
Are you guys sure the actual channels are being swapped then recorded swapped or just the meters are being swapped and it is still recording like it is supposed to? If it is recording swapped then this is indeed a big fucking problem.
-
I've used pause fairly extensively, but I haven't run into this. Maybe I'm just not leaving it on pause long enough. Hmmmmm.
I'm curious if it remains bit-perfect aside from the flipped channels, i.e. flip the channels back to where they're supposed to be and see if it matches the original file. I'm not in a position to do any testing at the moment - anyone wanna give this a try? If it retains bit accuracy even though the L/R are switched, it's easy enough to flip the channels in post production on the PC = IMO, not a huge deal. And if it doesn't, still BFD as I just won't leave the sucker in pause. It's just as easy to get it all set to go and just press Play when it's time, only takes about ~2 seconds to start the recording (still faster than starting a DAT recording that's not already in pause).
-
Yes it is easy enough to do it in post, but how to do you *know* when it has done it and when it hasn't? That would be the biggest problem I think.

I usually spot-listen the recording when I get home just to make sure I didn't completely screw the pooch. IME, identifying swapped L/R is plenty easy (I've done it enough times setting up my mics R/L instead of L/R!).
-
yea, this isn't really new. i've heard about it for a good while now. still haven't been able to pinpoint if it just swaps meters or actual channels though.
-
i mean no offense by this, but why pause the unit at all? i've been using my jb3 for about a year and a half and have yet to have to pause it. so just wondering.

sounds like a great project for ya, Brian!

Heh. Maybe after I move. But I think I'm gonna do a Canare StarQuad v. Audio Magic HyperConductor mic cable comp first. ;D
-
I may do some testing tonight if I am bored enough...not the bit-accuracy stuff but just testing to see if it does indeed swap channels on the actual recording.

Ya, I definitely noticed the one time that it happend to me while listening in playback...

so that its ready to go if the band comes on stage, to make sure its got a digital signal ect...

No, it isn't new with the meters switching. But it is a new issue with the actual channels swapping.

Bump--anyone have a chance to do any testing?
