Hey! My recording from last night has random digi-pops throughout the show. Not loud, but noticeable.

Any suggestions?

yep, it doesnt sound like ist a jb3 issue, buit we'd need more deatils tho

waltflanagansdog · « **Reply #3 on:** March 19, 2004, 11:23:09 AM »

I am about to test here at home. The UA5 was on all the right settings.

I'll let you know what happens. Thanks

What firmware do you have?

waltflanagansdog · « **Reply #5 on:** March 19, 2004, 01:30:08 PM »

1.32.02p

I bought a new optical cable, and I am Still getting pops. What else should I check?

mgleason007 · « **Reply #6 on:** March 19, 2004, 01:32:56 PM »

Your toslink > mini toslink adapter

How do you mean?

mgleason007 · « **Reply #8 on:** March 19, 2004, 01:36:54 PM »

Well if you have a standard optical cable you need an adapter.

Like this:

FWIW, I'm on the same firmware and have no problems.

Do you get the same pops via coax output (say, to a DAT deck or soundcard)?
Is your UA5 self- or Oade-modded?

waltflanagansdog · « **Reply #11 on:** March 19, 2004, 02:10:54 PM »

I do have a mini-plug, but it is all plastic.

There really is no way for me to test the coax out, I don't have a DAT.

I self modded my UA5.

fozzy · « **Reply #12 on:** March 19, 2004, 02:15:05 PM »

I too am on the same firmware running a self modded UA5 w/ a ratshack toslink to toslink cable w/ a ratshack toslink to mini adapter.

I do not have any issues. How are you powering you UA5? Is the unit secure and not moving around a lot.

Does the mini-plug seat firmly and click? Is this an isolated incident?

waltflanagansdog · « **Reply #14 on:** March 19, 2004, 02:17:01 PM »

This is the first time this has happened. The mini-plug used to sit all the way in with a click. Now when i sit it all the way in, I get zero levels.

I am powering the unit using a RC battery. The same setup that I found on here last summer.

While recording something off the TV, I jimmied the optical in a little. During playback there was a lot more static when I was messing with the cable.

mgleason007 · « **Reply #15 on:** March 19, 2004, 02:19:43 PM »

I am by no means an expert on this but I bet your min adapter isn't seating properly. There's a link somewhere about griding down the bit of plastic above the optical/line in. That is supposed to help the plug fit in all of the way securely.

good call 007, forgot about that one, its in the archival section under 'jb3 info';-)

fozzy · « **Reply #17 on:** March 19, 2004, 02:23:19 PM »

oh yea and i did this mod too. It seems essential to get a good connection.

I have already modded my JB3 with the dremel tool.

F.O.Bean · « **Reply #19 on:** March 19, 2004, 02:24:51 PM »

then its GOT to be a cable, process of elimantion!!

waltflanagansdog · « **Reply #20 on:** March 19, 2004, 02:30:03 PM »

OK, I got the mini-plug to click in the optical in and got levels...but still got digi-pops.

sleepypedro · « **Reply #21 on:** March 19, 2004, 02:32:33 PM »

is that dremel mod necessary for optical linking as well? or does the improperly seated cable channel-swapping issue only happen if you're running an analog cable into the jb3?

fozzy · « **Reply #22 on:** March 19, 2004, 02:35:45 PM »

i've never had to do a disk cleanup but that may help. Do you know anyone else w/ a jb3 or something that will take an optical input to run some tests to try to isolate UA5/jb3/cable. When you did the dremel mod do you think you could have gotten some crap in there(canned air). I'll shut up now cause i'm really shooting in the dark.

good luck

waltflanagansdog · « **Reply #23 on:** March 19, 2004, 02:37:47 PM »

Please don't stop. The ideas have me running back and checking the unit. I do not know a soul around here who owns a JB3.

I did the dremel mod a couple months ago, and have recorded a bunch since then with no problems.

I will try a disc clean.

depends on your input cable. YMMV but I cant see how any cable would ever seat properly in the input jack. I don't think i even turned my JB3 on before i did this mod.

F.O.Bean · « **Reply #25 on:** March 19, 2004, 02:39:20 PM »

format first, that way you dont lose your personal settings, at least on the latest firware thats how ya do it!!!

waltflanagansdog · « **Reply #26 on:** March 19, 2004, 02:41:14 PM »

i forgot how to get to the menu that allows formatting and disc cleanups.

fozzy · « **Reply #27 on:** March 19, 2004, 02:43:57 PM »

formatting instructions: i believe it's in the archives or somewhere on the nj3 yahoo list FAQ.

brandont_h · « **Reply #28 on:** March 19, 2004, 02:52:57 PM »

Out of curiosity, have you tried monitoring off the UA-5 to see if the sound is definitely happening between it and the jb3? One time recently, I was running my UA-5 at 44.1, to a Sony D8, and I could hear this popping noise while in rec/pause mode. It went away if I switched to 48khz. I've never heard it since on either sampling rate. Sometimes weird things happen. *shrug*

waltflanagansdog · « **Reply #29 on:** March 19, 2004, 03:11:44 PM »

GOT IT!!!

I pulled the mini-plug out a bit until I felt a click. Recorded 10 minutes of the Cincy ball game...POP FREE.

Thanks a ton for everyone's help!! If the problem arises again, I will be sure to check back!

Thanks again.

Mike

So you think you had the optical pushed in too far?

fozzy · « **Reply #31 on:** March 19, 2004, 04:03:08 PM »

I would try a different mini adapter to see if it doesn't require backing out.
If it is the case that you need the optical cable not plugged in all the way, this could be a fairly volitile situation in the field. I would recommend creating a "stop" w/ a thin piece of electrical tape at the base of the mini adapter.

let me try this in ascii
