Feature:
Simple and usable feature set - sweepable (parametric) eq for high pass filter - 48v phantom (if used that way) level and "warmth" (gain) knobs - a no brainer, never even opened the manual.

Quality:
Made like an old preamp - metal. Knobs feel a little light (by old standards), but quality nonetheless.

Value:
I see people spend more money on beer in a weekend - personally, I'll take tubes any day.

Desirability:
Tubes, lights - analog meters - smmmooooth...

Sound:
Lets qualify this by first stating that I can only fill my tank twice for the money I spent on one of these - I bought four. That being said, the internal boards are so simple, there is literally no much of a chance to "screw anything up", but in agreement with the prvious poster - let's definitely not Behringer bash - especially in this case. I have a lot of gear, including the Ampex 300 preamps from RCA studios where Sinatra recorded New York, New York. Case in point, those were originally front end preamps on Ampex 300 tape machines - the machines were in sad shape mechanically, but these amps, removed from the tape machines are great for studio preamps - and the sound of the Behringers (important: replace tubes with Ei Elite 12AX7EG - Telefunken clones) are as good - even better in some applications (with the Ei Elite 12AX7EG tubes). The downside to the units is replaceable - the stock tubes make a great unit noisy out of the box - an $80 upgrade makes this a world class preamp. I run every sub (8) on my Mackie ONYX 4880 through these on the sub inserts - all the time - people are always asking "how I get that sound" - thanks Behringer.

Ease of Use:
It's a preamp - if that is hard to use - perhaps a career in pet supplies would be more suitable...

Support:
no reason in over two years of everyday use.

Overall:
These units have become a staple - I keep another set of four in storage, along with tubes - "just in case"

Feature:
Rack mountable, nice look, fake tube lights are cool. BTW Presonus has a red LED behind it's tube. Heard people complain about the meters. Mine are working fine.

Quality:
For this price the construction of the chassis is good. The knobs are light and click in tiny increments. Very basic stuff here with a vintage retro look.

Value:
Return on investment is excellent.

Desirability:
chicks dig the lights

Sound:
Acts more like a DI with tube influences. I like the sound better than the Presonus tubePRE, much quieter. The coloring is transparent, the signal is strong. You will notice how dynamics will improve.

Ease of Use:
Look, read the manual. Line levels should be good going in, especially when miking amps. A little adjustment on the gain in the preamp, and some warth, and you are set. I do a bass straight in, sounds sweet by the time it reaches the board. My condensor mic sounds good with this unit.

Support:
Never needed it

Overall:
Some very good material was made on equipment alot more inferior to this. Let's not Behringer Bash. I reccomend this for someone who wants a more polished sound during tracking. That makes mixing alot more pleasurable.

Feature:
I use the high pass filter a lot to kill off the subliminal lows coming from my podxt. Works reasonably well and really cleans up the mix.

Quality:
The knobs are all plastic so banging this thing around would definitely damage it. Also, the stock tubes are garbage (they even horrible when I tried them out in my guitar amp as well). A tube upgrade is required to make this thing sound good. Otherwise seems like it will last pretty good in a studio environment which is what it is made for. One of the funky lights behind the tubes has burned out already but I guess I don't really care about that anyway. May take the other one out too rather than replace.

Value:
I found it well worth its price, even with the NOS tube upgrade not much else can touch it for the price..

Sound:
Out of the box, the sound is decent. You definitely notice the harmonics but they aren't as crisp as they can be. I invested $20 in some NOS tubes and WOW! Tiz a HUGE difference and really makes this thing wake up. Rating 8 with stock (behringer?!?) tubes, 9.5 with some old NOS tubes..

Support:
As mentioned above, there were no instructions for how to change the tubes so I fought with it for awhile. The top doesn't "slide" off the back, it has to be pryed off from the side it turns out. Simple maintenance instructions would have helped this situation as tubes especially DO need to be changed occaisionally, even if you don't change the stock ones out initially.

Overall:
I expect to use it until it dies or until my financial situation is such that a premium tube pre becomes an option. You can never have enough different tube pres. If it were stolen whether I got this one again or a more expensive one would depend on my finances at the time. This is the pre in this price range..

Feature:
Very straight forward. I do wish it had an insert, though.

Quality:
LED on one of the input gain channels stays lit.

Value:
Worth more to my ear. But I don't have that much of a frame of reference.

Desirability:
It sounds good. Gain and a little warmth with no noise.

Sound:
It sounds wonderful. Both my condenser mic and my bass sound great. And it is quiet as a mouse, too.

Ease of Use:
Turn it on and go. I read the manual prior to receiving it and was very informative.

Support:
Haven't called on this unit. Probably won't get it fixed. Too minor.

Overall:
I will probably buy another just to modify.

This thing looks like it was pulled out of an old submarine, but it has a beautiful clarity and warmth about it. It is a very cost efficient addition to the working-man's home studio.

Just a great piece of gear....quality components and construction....not to mention clear, crisp sound that is not only transparent but also adds the warmth of tube. Be sure to swap different tubes to get different flavors...I have a JJ/ECC83S in channel 1 and a NOS Phillips for Channel 2...one word.....WOW!!!!

Sound:
Works great, It's blows away my junk Focusrite's. After two years of daily use it's starting to get a little more "noise" in the signal,not so much that I can't mix it out, but at this price it's one of the best values I've ever gotten period. I wish I had four more.

Support:
Have not needed it

Feature:
Features are simple. I wish Behringer would have built in 3 tubes per channel instead of 1. Maybe that would increase the "warmth" feature??

Quality:
Although "warmth" feature is not as strong as I'd like it to be, this is unit does produce a very, very clean sound even at high volumes.

Value:
Worth trying is you are looking for a very clean sound. Although I like the unit, it should have been a bit cheaper.

Desirability:
Nice construction.

Sound:
An OK unit for a little gain with line in applications. The "warmth" feature is not as good as ART products, and is only noticeable at higher volumes. I have only used this with bass guitar enhancements and don't know how well it does with acoustic guitars and microphones.

Support:
N/A. I've never had to call for support.

Overall:
8 out of 10. Not bad.

Feature:
Has phase reverse, adjustable high pass and a knob that allows you to adjust the amount of signal running through the tube.

Quality:
I have only had it for a few weeks, but it seems well built.

Value:
It sounds good, FOR THE PRICE. Having worked with one for a few weeks now on serveral recrdings I think that I would save a little more money and buy a better preamp.

Desirability:
It looks cool, but don't be fooled by the look. Buy audio gear for how it sounds. This thing has lights behind the tubes to make the tubes look like they are glowing brightly. Behringer probably spent more on designing the look of the preamp and the glowing lights, that fade in when you turn the unit on, than they did on the design of the sound.

Sound:
The sound is OK. It is good if you don't have the money, but I would save up a few hundered dollars more for a better unit. It is a little noisy and the "warmth" is a little muddy.

Overall:
I bought this thing a few weeks ago and I am already looking at replacing it. It is hard to know how a piece of gear like this is going to sound in your set up until you buy it. I have a Bellari RP220, a little more money and doesn't look as cool, but sounds a lot better (cleaner mids). This thing has muddy sounds all throughout the 500 to 1000 hertz range. The only way that I would buy this unit again if it were lost or stolen would be if I needed it for a project, didn't have the money to buy anything better and didn't have the time to save up for a better unit. Bottom line, save up for something better.
