Title: JB3 help for a simple guy
Post by: theGrape on July 07, 2004, 11:18:56 AM
I bought a JB3 with the intent to replace my MD "rig".

I have CoreSound Binaurals with a bass rolloff batery box. I do not want to add an A/D to this. I know that limits me.

What should I be using as setting on the JB3 to record? I made some attempts to test this at home and was not impressed. I figure I'm doing it very wrong. My test source was my stereo at very loud volume.

Sorry for being lame.

Thanks,
Grape

As a CSB/JB3 owner I can tell you to always go line-in, +12dB and get as close as you can.  You'll never have enough for good levels.  Also, the CSB connector will not properly insert into the JB3 until you shave it down like this  (http://ca.geocities.com/dkleined@rogers.com/audio/JB3input/JB3_input_jack.htm)

I seemed to have trouble with the channels, so I think the shaving needs to be done.

Your signature shows an A/D between the CSB and the JB3. Can I run this without it, or will that be foolish?

It will work ok for loud shows and not so well for quiet shows.  You'll find that you need to boost the levels afterwards, and that can bring about the hard drive noise.  Although my sig says AD20, I haven't even run it yet.  I've done a bunch of CSB>JB3 recordings without it (subject to the problems above) and when I saw a good deal on an AD20, I jumped on it.  As I said, I haven't run it but it is a really nicely crafted piece of gear and costs <$200 used.

The a>d in the JB3 ain't too awful but the gain is an issue with mics plugged in directly.  I'll put up a song that demonstrates it all - how good the JB3 can sound along with the hard drive noise.  This was recorded at a theatre, show was not very loud, CSB>JB3 line-in @ +12dB.  I was in the 2nd row off to the side - most sound is from the stage monitors and direct (especially the drums).  I was seated and the mics were shoulder mounted - what I like to call the 'body baffle' - a little bit of flesh between the mics and the noise from behind. The p.a. was way above - we were basically under it.  Then I had to add another 23 dB afterwards, for a total of 35 dB of gain.  It will help put the hard drive noise into perspective - it's there on the quiet passages (listen at 0:09 for the beep).  Once you've heard it, you'll continue to hear it throughout.

-edit - link down - pm me if you want it

Any one who's interested - give this a listen - it's an awesome Bruce Cockburn tune!  And although this recording does have issues, there's no denying the 'natural' sound of a pair of omnis in this cardiod dominated world  :o

Sound sample sounds great all things considered.
Is there no bass rolloff box in this equation?

Looks like all I need is the shave on the input jack.

I don't hear any "hard drive noise". I'm using very good Sennheiser headphones to listen.

(and tell your friends not to clap so loud  ;)

Now I'm hearing some noise at the end of the track -

There is a battery box but it's set to flat (no rolloff).
