Hi All,

I've been doing some research into the Art MPA II Tube Pre Amp and wondering if anyone has one or used one and are they any good for improving vocal quality?

I used to use the first model. It did give a warmer tone to the sound, owing to a vacuum tube. I believe it was a compressor as well.

Hi, what did you use it on? Vocals or instrument?

PH.

fyi ive done thousand of vocal tracks over the years useing everything from a 50 buck art to very high end commercial studio consoles and outboard pre's.
maybe others will disagree but comparing the final mixes i would say the consumer buying your song from my tests anyway is more interested if the song floats their boat.
in conclusion imho assuming the pre is working correctly i would say the trick is how the vocals are treated post recording.

if you doubt me there is a highly entertaining lengthy thread on gearspace.com where audio examples are posted re 50 buck art versus higher cost fare to see if people could tell the diff without knowing which was which. the reveal was a hoot.
just search gearspace for it.

if you are concerned just rent a bunch of pre's for a week from a gear store and record vocs with each to compare.this should assuage your concerns. do your own tests.

in summary i believe there are other things to worry about other than the pre.
for more info you tube has lots of comparisons.
now i'm gonna go do some vocs on an old germanium transistor pre..lol.
ps also on gearspace is a hilarious thread comparing the legendary
diy 5 dollar pre versus high end stuff.

happiness.

I guess I'd first have to ask, what kind of Mic are you using?

That could make a lot of difference in any answers I could offer, and I would hope it would affect others input as well.
Also, what did you have previously to compare it to?
Since you asked if it might 'improve' the vocals, that is a comparison that would need the starting point. A vs B ..

I agree with Harv.

The best thing to spend your money on is a great mic, and of course you need a good interface.

Almost every other treatment these days can be done with software in post prod.

But that is just me. Everyone has their own "sound" they are going for.

You may need an old 1950s ribbon mic if you can find one for 10,000.

I boughnt one of these quite a while ago
https://www.soundonsound.com/reviews/behringer-mic100
it gets good writeups and is amazingly cheap but frankly i stoppped using it as the recorded tracks were not significantly enhanced and I get good results using eq and other fx quite sparingly on a signal from a condenser mic straightr into the behringer UMC204HD which i presmu has much the same preamps but without the tube.

Thanks for your reply. I'm always keen to consider anything that improves my vocals. I lack confidence and am a perfectionist. I hear my vocal flaws and do my best to iron them out.

Thanks for that. I have LOADS of plug ins. Spent a few hundred ££ on WAVES plus a lovely Lexicon Reverb set of plugins and others including those from StudioOne.

So I bought one to try out of curiosity. I've used it on my Takamine & M88TG and on both multiple test recordings both sounded better in that recordings were fuller & warmer I would say. Presonus although clean sounding, sounds thinner by comparison. It's a keeper. Looks cool on my desk also!

Thanks for the update on your experience with it.
Yes it does look cool.
I'd be interested to know how the variable Impedance works in real life.
Can it handle both a LCD and something like an SM-57 or SM-58 OK?
An SM mic (or similar) would benefit from much different settings.
It looks like each channel can have it's own impedance, so that would be nice.

var impedence.

For those happy with current pre but no var imp feature...never used but art have a new product called rp1.
it has a variable imp input. for ribbon and dynamic mics.
so one can go i guess as follows
mic to rp1 to next device in chain.
it also is a signal booster.
for more info see arts web site.

for other similar var imp gear and boosters.
just google. eg i just came across alctron ?

hth.

I've only played with it a little so far but have tried two mics - Beyerdynamic M88TG and Rode K2. Both have a 200 impedance. I've cranked it up higher on both and lowered down to 100. I'm not sure how I would explain the difference? Its subtle. To me my mics sound warmer around 100. Pushing it higher (600+) and there seems to be more detail and the volume seems to increase slightly. I think I prefer the warmer effect if that's what you call it?

I used those mics as a reference because their reported impedance is lower than a lot of them.

"Rated impedance is 150Ω (310Ω actual) for connection to microphone inputs rated low impedance"

The others probably appear louder and clearer when higher because that is the impedance they expect.
Starving a mic is different than giving it too much, so the two mics you used and the two mics I mentioned would likely show different results to the ear.

So many SM-57 and 58's out there still in use, but many interfaces do not have a way to adjust for them.
I have a separate preamp that works just fine, and if I insert it before the interface it's fine. But having an interface that did it in the first place is a nice feature.
That said, my Preamp also offers the additive tube feature .. so works a treat on other stuff as well.

If that ART has an 'instrument' in switch, may be fun to se what your guitar or bass sounds like through it.
