could someone please explain to me to difference between the XLR
balanced outputs and the 1/4" unbalanced outputs of the VMP? i've read
people reference an article that said it might be better to use the
unbalanced outputs of the VMP-2...i can't seem to find that article.
i'm wondering why that is, perhaps someone could point me to that
article...

thanks!

There's plenty of information around and about describing the
difference betwen balanced and unbalanced connections. One of the best
is he http://www.rane.com/note110.html

I've read

I remember that, too, but I don't remember why. Seems to me that it was
a pretty weak or marginal argument. Perhaps it's because the balanced
output goes through a so-so transformer or additional electronics so
the unbalanced output is a simpler (and therefore cleaner) signal path.
There could also be a difference in maximum output level so that one
would better match whatever you're connecting it to than the other. But
for a fairly short cable run (less than 25 feet or so) it really
doesn't matter unless you're in a place with a lot of electromagnetic
interference.

If you're curious enough (and you should be), try them both and see
which one works better in your situation. If you can't tell the
difference, use whichever one is most convenient.

that makes sense. i ask because i wanted to use a VMP-2 into a RNC, but
was hesitant beacuse of the RNC unbalanced inputs. but if the
unbalanced 1/4" ouputs of the VMP are cleaner, then i'm no longer
hesitant to use the RNC!

i had one of these and had Jim Williams at audio upgrades mod it for me.
The upgrade was fantastic, and Jim also suggested using the 1/4 outs
instead of the balanced outs. If i remember correctly, he said to do so
because the output transformers were really horrible, and were proprietary
to the unit so replacing them wasn't an easy option.

I used both and the transformers really had a "sound", for better or
worse.....

interesting. thanks so much for the help.

Look at the schematic that came with the thing. Notice that the unbalanced
outputs come off of a cathode follower _before_ the output transformer, while
the balanced outputs come off _after_ the transformer. This is typical
tube design; it's a major pain to electronically balance outputs in the
tube world, so everything gets transformer-coupled. Transformers change
the sound... whether this is a good thing or a bad thing depends on the
sound you want.

IIRC, the deal is that the balanced allegedly +4 output won't actually
swing that without a lot of distortion.

And don't forget, the VMP-2 makes an excellent EQ. Just use the 20 dB
pad for line level.

I wrote that article, quite a few years ago; it was a review of the VMP2 for
Recording magazine.

In essence, I found that the balanced outputs had higher distortion and a
nastier harmonic distortion spectrum than the unbalanced outputs.

Peace,

great, thanks so much.
