MGR/Billy's review"Behringer Tube Ultragain Mic100 Preamp and DI with Limiter"

Behringer Tube Ultragain MIC100
This is a the table top model, not a pedal or is it a rack unit. It's about the size of a standard DI box or external hard drive.

These run about $50. I picked it up to find out if it really does all it says it does for $50. You can get them just about anywhere that sells Behringer products.

I like the the unit is cheap. It's lightweight. If it broke in 6 months I would not be heart broken nor angry. You get what you pay for.

It will 'warm up' your signal with a little bit of tube warmth. Sure it isn't going to sound AMAZING, but if you're on a budget it's a great unit.

I like that it has an XLR input as well as an instrument input. I can use this for vocals or a guitar. The -20 DB is very helpful.

Power is great. You can power it through Phanton Power, a power supply or by a 9 volt battery.

The Limiter is very limiting. You can't adjust it other than your gain and output volume knobs.

Since the unit is cheaper the construction is not on par with what I think it should be for a pro situation, but hey pros don't need to worry about budgets right?

I mentioned before I do not think the construction is up to snuff. You will most likely set this on top of your amp and sooner or later an instrument cable with get tugged or stepped on and this unit is going to come crashing to the ground.

I don't think it would absorb a fall, but I have not dropped mine either. I was very careful to gingerly use this.

Bottom line is if you need a guitar, bass, vocal or keyboard DI are are on a budget it, this is great. It will get the job done for you without too much noise to boot.

It will warm up a brittle sound to an extent but the Behringer is not a miracle worker.

Maltigow's review (This content has been automatically translated from French)" Good cheap solution"

Behringer Tube Ultragain MIC100
Analog preamp tube (12AX7 low voltage, I doubt very much that it brings), supplied with specific power supply.
Mono input jack + XLR outputs for the same.
Switches: limiter, attenuator, phantom and reverse phase.
Seen the light meter for saturation. (Diodes)
Compact, solid, very complete.

I take off a point for the stupid argument "lamp" which seems to me essentially commercial.


Very easy to use.
I found the manual clear, I'm just used to check what he endured as connectivity (both outputs can be used simultaneously, for example) and I quickly found the information I needed.


It remains a cheap preamp that goes well beyond, and I am very happy because I did not need more. The sound is ok, and the connection / setting impeccable, so we do what we want, and so far the machine seemed very reliable.
Point of his view: Clarity ok, S / N ratio ok, does its job, sturdy, not bulky.
My use: Repeats homestudio for microphones (vocals, guitar amp transplanted) or my electro-acoustic.
Another use that I found interesting with my Tonelab:
Guitar -> Tonelab Desktop -> MIC100 -> mixing desk and amp XLR jack return.
It is a versatile tool, correct, and good to have on hand.


I bought used in 2006 or 2007, it has not moved since.
Not really ... Apart compared with the MIC200, but I have not seen the interest instrument selector on this unit ... The only preamp enough.
I would do this choice without hesitation, as adapted to my needs.

Sphinx's review (This content has been automatically translated from French)" Better than the most expensive!"

Behringer Tube Ultragain MIC100
1 channel tube preamp.

Jeck connections and XLR input and output.

Gain Control (lamp).

Volume control.



Phase inversion.

Phantom Power 48V supplies.

Metal shell. Generally well finished and looks pretty solid.

External power supply.


Very simple to use: nothing really rocket science!


Almost not breathing! Even with the gain cranked, it is reasonable! Compared to other preamps lamp input range, but still much more expensive (up to 150-200 euros), the day and night! There is hardly any breath with a gain already, so who therefore is perfectly usable, compared to most competing products at this range.

on the other hand, nearly nonexistent color lamp too!


It is therefore especially a small booster-Swiss Army knife of sound quality surprising. It is ideal for people who want a cheap preamp, with the possibility of adding a (very) slight coloration typical "lamp".

If you want a stronger color, then there are two options: buy a much more expensive amp (from 300-400 euros for 1 channel), or changing the lamp.

I currently have a mesa boogie lamp in stock to test, but I have not yet been tested. It is not the loss of warranty stops me (product price "ridiculous"). But I lack time right now (not to write this critique, however!: O))

I would do this purchase knowing what it implies: good boost with decent sound and little or no wind depending on the level of gain used. Swiss Army knife. Ability to change the lamp for a superior (not tested yet: I do an update when it is done).

NB: I have not really tested the limiter. It will also refresh during the test lamp replacement.

suntsu's review (This content has been automatically translated from French)" Excellent value for money"

Behringer Tube Ultragain MIC100
This is a pre-tube amp with a very simple input gain, output gain, limiter, phase reverse and phantom power +48 v.
connectivity available is as follows: an input jack 1/4 ", an XLR output Jack 1/4" and XLR output.
The format of the machine is relatively compact and highly resistant (metal case)


Operation is extremely simple manual not need to master the six buttons that control the craft.


Contrary to what one might think, the light of this pre-amp makes no noticeable heat on her. Against it is highly transparent and has good clean gain without distortion up to about 2/3 of its maximum power. It is quite possible to change the lamp current to another and get better quality and more analog coloration.


I use it for almost 2 years or more and I am completely satisfied, the value for money is unbeatable and for once Behringer has not planted because their products are not always on top ;-)
So if it all over again I would do this purchase with your eyes closed!
Small bb for limit which is not great.

Behringer Tube Ultragain MIC100
Preamp lamp
see Opinion Previous


Bought used without the manual but it is super simple ...


With the original lamp, the sound is ultra-transparent, one finds almost no heat lamps: Too bad. saturates at a 3 / 4 gain. The original lamp is not bad for a color lgrement bass amp transistors or to the taking of a man singing badly studio grs it lacks personality.

APRS have it plugged into a guitar with a light grip on my sovtech vieu JCM800, this small box becomes prampli / overdrive with a nice 70's trs. aadj many more characters and saturates one third of the gain.
It will try that with a lamp that rises over the gain to see what happens. ds as possible I would test with a lamp that warmer does not saturate to test its capabilities in clean ...


I use it for 15 days for Russia to understand what I'm going to make this prampli.

I like the simplicity of this box. I have an old amp peavey 200h pramp which is ultra cool. This preamp will allow me to add a tint "lamp".

I bought it used less than 15 euros shipping and power supply included. So what is the price is a bargain.

I do not really need a pre amp first set. But this has taken the same I would do certainly BTIS.

lonely_lou's review (This content has been automatically translated from French)

Behringer Tube Ultragain MIC100
Versatile tube preamp (12AX7) for condenser microphone (there is a phantom power) and dynamic as also functions as direct box: ie of an XLR input to an output jack or XLR input jack of course.
knob a gain, an output.
No effect but a very useful limiter, 20dB pad, phase reverse.
A sound processing for I quote "give more heat to dull recordings sound cards"


Very simple: plug in, play niaah
Trees easy to adjust but the problem is not to lose its volume settings when the scale and imprecise (no real value markers on pots, count the lines is not practical ..).
The manual is useless so it's childish


I have not had time to push back the test but I was very pleased with what I could do for now (making a voice for a whole song and a few test recordings guitar): He brings a warmth to the voice that I liked! very happy! As for the guitar because the sound is richer and warmer, also clear.
Not breathing, background noise or hum!
Lack can be a bit of color (especially a grain)


The most: the quality / price ratio, the heat of her, the versatile side, simplicity
Cons: sempble me a little weak, All that's missing is the modeling of his little brother Mic 200 (but hey nothing beats its own settings for those plant ..), while the bulk remains less The same lack of ON / OFF button (it should pull the plug to turn.
But for now I am very happy with my achat.Rest still one last point, I think this preamp is rather intended for the home studio to the stage (not robust enough for my taste).

juniorstarr's review (This content has been automatically translated from French)

Behringer Tube Ultragain MIC100
Tube amp with a pad-20db, a 48v, phase reverse and a limiter, XLR or jack.


2 buttons to spin .. dosing should know that's all.


I ride the volume knob a quarter output, otherwise it is true that there is a little breath BEYOND ..
To remedy this I strongly advise you to change the 12AX7 MESA base against a lamp that costs 25, and you end up with a warmer sound and, above almost out of breath.


I use it for a year, I bought a phantom power supply for the base, and because, as almost everyone who bought the behringer, I did not have a lot of gold coins.
I use it for making hip-hop voice, it really good cash, the limiter is a parcontre avoid, it is not the point.
It is clear that the price should not be too hsiter is a good buy if you do not have too much money and want a record of quality parcontre as I have not above, if you can change the lamp, Do not hesitate, replace the Mesa by a lamp and you have a very nice surprise ..

Behringer Tube Ultragain MIC100
See gnral


See gnral, but simpler you die


Well clearly the different views. I use it to bring the sound of my Oktava MK 319 in the box on my 20bit Gina. To me (but I am not an expert), no breath and no coloration. The sound is Fidler, less hot than when a bullet went through my CAT, but as it took for me to spare, this little thing is just fine for 36.5. There would be a big diffrence and breath based lamps embedded device. Rumor vrifier.


I've had a month and I am glad trs. I use it for voice-over or records for models and sounds spot on. It dpanne trs well, it's easy to use and my setup is nickel.
