...they don't work. The 1/8" plug on my CSBs (purch. Nov 2001) has a rather wide barrel that is too large to completely fit into the recessed input on the Jukebox. It's hard to explain but if you have one, you'll see what I mean. It's really just a combo of the the 2 designs. I've only had it happen on the Jukebox, but at the same time, every other 1/8" plug I tested on the Jukebox did make a proper connection.
I'm sorry to say it took me 2 failed attempts to figure it out.
First time I used line in, without gain (which admittedly was dumb because the CSBs purposely have low output for brickwalling Sony DAT preamps). Levels were low but I'd heard that the JB3 preamp wasn't so great so I figured I'd go line in and boost it later. The sound was crappy and thin but I thought it might be some side effect of having to apply ridiculous amplitude adjustment.
Second time, thought I'd avoid problem #1 by using the JB3 preamp to hit some decent levels. Got great levels. Recording sounds like shit. I can duplicate the sound by taking a source thru 1/8" and pulling it out partway.
A little more playing around revealed something very strange happening to the sound because of the partial insertion. I'm not quite sure what contacts are made on a partial insertion but I can hear both mics in both channels and a paste invert of one channel perfectly cancels out the other channel - in other words, mono. But not nice sounding mono.
The solution - change the plug on the CSBs (don't much care for that cheezy gold crap anyways). And yeah...I'm one of those people who would respond to this by saying "you should have tested it out" so no need
Now if someone can tell me how to decode my lifeless mono recording back into a real one, that would be useful information - I really wanted those shows! (SARS concert in Toronto w/Kathleen Edwards, Flaming Lips, Guess Who, Rush, AC/DC, Stones and then Jayhawks/Kathleen Edwards at Molson Amphitheatre...in case any else did get them)
Sorry for the cross post if you're on those 'other' lists.
