Casio CZ/ VZ/ FZ - Pro Series

Hello all, I just joined this group to get the VZ programming pdf in 
the files section, but I just thought I'd share my VZ joy with you 
all.  I just bought one, brand new unopened in the box for $100.  Now, 
I've been using midi gear for over 15 years, and aside from my first 
two synthesizers, purchased with an insurance settlement, I've been 
relegated to picking up whatever I can find very cheaply on the used 
market.  So my rig is not pretty, much of the equipment is beat up or 
had to be repaired before I could use it.  So what a joy it was to open 
up a brand new VZ, with all the little accessories that most people 
have probably lost by now.  The pouch for the ROM card, and the plastic 
cheat-sheet cards, for example.  And did you know the VZ-10m originally 
came with a free MIDI cable, a 1/4" to RCA cable and the chunkiest 1/4" 
to RCA adaptor I've ever seen?  OH well, I had considered keeping it 
sealed in the box as a 'collectors item' since it survived so long 
there already, but I wanted to use it and unpacking it was so much fun!

Anyway, does anyone know for sure whether the XLR output is balanced?  
I suspect it isn't but I've been using it anyway since my 1/4" cables 
are in shorter supply than my XLR cables...
