Skjold's review"Great budget compressor"

Alesis 3630 Compressor
The Alesis 3630 sports a stereo/dual mono compressor with gates on a budget. I might have an earlier version of the unit, as mine does not have XLR connections, but only 1/4" jacks. As mentioned, you also get a gate, with fixed attack, hold and release but adjustable threshold.
The compressor is switchable between RMS and Peak mode, as well as switchable between hard-knee and soft-knee compression.


You get a basic and pretty much standard set of controls on the 3630 Compressor. So in case you have any previous experience with compressors, you should not have any problems figuring out how to operate this one.
The compressor section on each side, has controls for threshold, ratio, attack, release and output. Remember to set the sensitivity according to either your DAW or mixer. There are small slides on the back of the unit for this, which switches each channel between +4dBu or -10dBv (the later being called instrument level).

I've not had the need to look in the manual, but should you find the need for that, it can be found on the web.


This is were I've had some issues with the compressor. For some reason, the output is extremely low, even after finding a unity between input and output. This however has been on drums, so the unit might not be so useful for that particular instrument. I've not had any issues on the vocals.
I find it pretty amazing, that the sound of the unit on vocals is as transparent as it is (relatively). It's not the most transparent, but it doesn't color the sound that much either.

The gates are decent. You don't have any chance of changing attack, hold and release. It's find, if you just need to clean up a signal - i.e a distortion guitar with a lot of hiss, when not played.


This is not a high-end compressor, so if you own a home studio and are on a budget, this cheap compressor might be something for you. The quality is way better then Behringer, but below DBX.
The 3630 runs on a 9V power supply, and this might be the fall for this, in other ways, fine compressor.

yoTrakkz's review"easy to use"

Alesis 3630 Compressor
The Alesis 3630 is an analog compressor/limiter. It has XLR connections in the back and is rackable - it will take up a single rack space. The metering is smartly made and the bright LEDs help you to see exactly where you level is at.


The configuration of the Alesis 3630 is pretty easy to follow. It has a knob to set the threshold, a knob to set the output gain, and a knob for compressor ratio. It then has a buttons for bypass and to change the display of the metering. I don't have a manual for this so I don't know if it helpful or not, but the unit is easy enough to use that most shouldn't need it except maybe during set up or troubleshooting.


The sound quality of the Alesis 3630 is pretty good overall. It is good for drums and guitars, but lacks the full quality I would look for in a vocal compressor. The ease of use makes it quick and easy to get a good sound and the bypass button is handy when A/Bing your signal. It is nice to have a few of these at once while you are tracking if you like to track drums with compression.


I've been using the Alesis 3630 compressor for about two years or so. While this isn't the best sounding compressor out there, it is very solid and works great for drums. The price is what will draw most to these, as they are quite cheap, but not cheap enough that they can be considered an entry level compressor. These definitely sound better than the Alesis 3630 and 266, but is a bit more expensive than both. If you are looking for some compressor that are a reasonable price and sound good, the Alesis 3630 is worth a look. Look around online, there are some good prices on this compressor.

R-skillz's review"Great compressor!!"

Alesis 3630 Compressor
Alesis 3630!! A Great stereo compressor with limiter & gate!


Clear manual


Punchy, clean & tight sound, Not so good for rock music or a live band. Great for HipHop, House, Electro etc.


Probably the best compressor for its price range, Great for mixing / mastering at Home studios and professional studios

moosers's review

Alesis 3630 Compressor
The Alesis 3630 Compressor is a stereo compressor that is quite popular among home studio owners.  This piece of outboard gear is analog based and has both XLR and 1/4 inch connections.  In addition to the compressor, this unit also features a gate.  It is indeed a rack mountable piece of gear and it will take up two rack spaces.


The make up of the Alesis 3630 Compressor is pretty standard all around, so those with previous experience with compressors like this one will be able to figure this out rather quickly.  Each channel has parameters for threshold, ratio, attack, release, and output as well as a section for the gate that has additional parameters for threshold and rate.  Both channels also have a variety of buttons including a choice between either soft or hard knee.  I haven't seen the manual for the 3630, so I can't say too much about it but I don't believe one is necessary unless you are a beginner or are having technical difficulties. 


The overall sound quality of the Alesis 3630 Compressor is pretty impressive for such an inexpensive unit.  It is suitable for a variety of instruments and applications and I've seen a lot home studio owners use it on just about anything.  I've only used it on two different applications in particular including electric guitar and drums.  I find that the type of sound that the 3630 works best for these types of applications, where you wouldn't necessarily be looking to keep the cleanest signal possible, as this isn't the cleanest compressor out there.  The gate sounds pretty good as well and is a great thing to have within a single unit like this one...


If you are a home studio owner looking for a cheap compressor, the Alesis 3630 Compressor should definitely be looked at.  The unit is built well and should last for a while as long as you don't move it too often and treat it properly.  In this price range, this is about as good of a compressor that you are going to get.  While it isn't the cleanest or fullest sounding compressor out there by a long shot, if you're looking for a reliable stereo pair that has a gate on it as well for a home studio setting, I would definitely recommend checking out he Alesis 3630 Compressor.

Alesis 3630 Compressor
It's good stuff. Alesis is a good builder and reliability of its products have made its reputation.


Its use is simple, intuitive and reliable.


I used the 3630 for all my instruments: Bass, acoustic and electric guitars.


Very favorable opinion. For my part I sold due to lack of use often, but when I switch to a more regular mode of production, I rebuke one!

krokodile63's review (This content has been automatically translated from French)" For informed public"

Alesis 3630 Compressor
Analog stereo compressor + gate 19 "rack
jack connectors standard


very simple, it is the most classic compressor
treshold, ratio attack, release.



This is where the 3630 is its charm, was reputed to have used by daft, stardust, Braxe and all the frenchtouch, the fact is that it compresses "evil" that is to say he has trouble to manage the low end ...
Ducoup when the kick comes into play and the bass is sidechainée we just weaker you this "pump". Pti with sticky side down in medium which gives it a very special color.
A use of a certain FCON therefore, a whole mix or batteries (ie music for house / electro is perfect). on the other hand I do not recommend it for pop or rock etc ...


Compression cheap but its a great color and a lovely (Listen Music sounds better with you Stardust is a perfect example).
Excellent value for money if you do not ask him too.
I possess also an ssl g series and I admit that I love the alesis anyway, for public informed ...
love the disco is cool
Love the rock is not cool

Alesis 3630 Compressor
Dual compressor rack.


Operation is simple (at the same time I did not fire in my beginners), several rglages can fawn simple paramtrer its action, as attack and release by example, it's like on a keyboard, sometimes the audio to work but also fun than working on a synth. Its operation follows several ways that the fawn dterminent which the compressor will act according to the trigger buttons (Peak / Rms) and (Hard / soft knee). It is possible also to by-pass very easy for a suitable key and another key to make its action, or Stereo or dual mono.
In terms of other controls, five rotary controls allow rgler threshold, compression ratio, attack, relchement and output level. A conventional compressor altogether. Prcis simple and clear indications are given.
The VU meters allow you to view the selection signal in and out, look the other way it's terribly convenient, and the intensity of rduction gain introduced by the compressor.


It is difficult to give an opinion gnral because I used to change only a few transient sounds coming out of my numriques keyboards, and he did relatively well. I noticed that it happened just like a veil, as if the treble taient Galissa dynamically by the ngatif. thundering.


He does my first compressor, and with it I made many mistakes, but it allowed me to make my Premire weapons in the world fascinate change the dynamics of sound.
In any honntet since I was with my husband, and that made me immediately find and use so many other models better, I have a hard return and the rear rutiliser Alesis.
Now I use our BSS DPR 402 that I love and who are more respectful of my work, they also allow me to work much more pushed and cratif. But I do not forget that thanks the Alesis, and (especially) thanks all the advice of my husband, I am normment progress, and this allowed me to use d other more sophisticated compressors on the one hand, and secondly, to use the same compressors Manir more calmly and intelligently.
Of course this compressor is not perfect, but I think it is a good tool to get your feet while providing a satisfactory quality at an affordable price.


stereosound's review (This content has been automatically translated from French)" Neutral electronically speaking"

Alesis 3630 Compressor
Classic compressor or limiter (in the ratio) 2 mono channels linkable (linkable) in STREO. Fully analog. SMD components. Rackable U/19 1. "Connector Jack asymtrique 6.35. Alim externally.
THAT VCA compression (I think).
A gate is also attached.


Simple, VU prcis nitre and Retailer. Slecteur the level of (-10 dBV or +4 dBu) is the rear. Must choose their camps before rack!


In terms of compression, the bandwidth is good trs. Trs prcis transparent and treatment.
Noise at the Gate: The rglage plutt is abrupt and a t expander would more appropriate.
At the pleasure of sound, it's pretty diffrent: RMS mode may be not good enough and we end up tudi quickly with his "mang if you have the fast attack times .
In fact, it should be used with a low rate and a long attack time, back even longer.
A relative Behring, I found it less "fun" in the perception of balance bass / treble, but also cleaner on the sound and with a proper respect for the trs width of the str o (low crosstalk)


I took these products as fairly good value qualitprix the era of the domination of proprietary dbx (80).
Example for which this product is IDAL: a limiter for protecting a couple amp / speaker for a concert. Its transparent rglages prcis, no breath and good protection of your sound system if it is a little weak or if you do not want gnrer of odd harmonics with a clipping evil master of your amps.
Treatment for voice / bass and another may be taking a compressor less neutral, with a brand and color for the type of sound source.
