The other reviews has already covered the pros, cons and features.

HOWEVER, I would like to re-enforce the fact that there's NOTHING wrong with this compressor, it's a great value for the money!

As with ANY compressor it will color the sound and there WILL be artifacts, REGARDLESS if it's a low end brand, OR a high end unit that costs 10 grand.

In reality there's really no such thing as a "transparent" compressor. Some are just a little better at hiding artifacts is all. For those who don't already know this, here's why:

Compressors/limiters reduce dynamic range, therefore you are DEGRADING the signal, no if's ands or but's. You are also adding distortion to it as well.

The key to using a compressor effectively is to make it sound like you're NOT using one. AKA, try not to make the compression artifacts such as pumping not so apparent... that is unless you're looking for that effect. Also, if you have "garbage" hiding in your audio signal, such as ticks, pops, high noise floor, Reducing the dynamic range WILL raise the overall volume and you will hear it.

Therefore, don't automatically blame this box if you cannot get a good sound from it.

IMO, I believe the reason the 3630 gets alot of bad reviews is due to the fact that many buyers are new to compression and therefore don't understand what's going on.

Some seem to think that you hook up the box and it "magically" makes your sound professional or something.

WRONGO! Just like different brands of studio monitors, Compressors also need to be learned. Therefore, take some time out and understand the 3630's weaknesses and it's strengths. ( You might wind up being surprised just how useful this budget unit actually is.)

The gate is pretty much useless (no attack relase or hold controls, just one crappy overall "rate" knob, and the threshold doesn't go high enough!!) and it is extremely hard to see the printing on the front.As far as the compressor sounds, it don't sound too good in my opinion. In most cases, I'd rather use no compressor at all.However, it is fairly cheap, and I guess it doesn't sound too horrible on really low settings, hence the slightly higher "value" rating.

      The Standard

      By Nightmare on Elm

      from The Mountains

      Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

      This compressor is the standard in this price range. It works very well and if you can't get it to, then you probably need to learn how to use it. This is not a studio grade compressor, but it a really solid, extremely useful piece of gear for live shows. I almost have to stop believing these reviews, it's almost painful to realize how many people cannot setup gear correctly and then blame the gear. I noticed the same thing on the reviews for rack-mount EQ's on here. Just a shame. Bottom line, good compressor, learn to use it correctly, it will treat you right. Been using one of this same model for a while now, works great.

      Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

      I have use this for bass vocals and up right bass for rockibilly and it has made a world of diference, always smooths out the sound and no matter how you set it up, its Super quiet (where most compressos would hiss) Ive used it for years now and love but never even needed the second channel. tho its good to have if I ever would need it
      not only is it the most versatile compressor Ive found but it has a solid working nois gate too
      never had any issue's. all the knobs work perfect so I would say its great quality. reliable work horse

      You won't get a better compressor for the money!

      By The Tannery Recording Studio

      from Milwaukee, WI

      Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

      As far as compressors go, there are two types. ones under $200, and ones over $1000. Somehow, this under $200 compressor sounds like gold. It has some weak circuitry and a poor noise gate, but it has extremely transparent sounding compression. This is one of two compressors in this price range that I find to be useful in professional applications. I have own $1000 and up compressors, but somehow, the 3630 still sees quite a bit of use in the studio. Overall, a great deal.

      Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

      Just picked up one of these this week. I was previously using a Behringer comp that i thought was doing a great job at keeping lead vocals tight and clean. I plugged this unit in and was absoultely amazed at how much fuller the voices sounded than they previously had. Several people came to me after the service asking what i did differently because the overall sounds was so much "fuller." I love it!

      from new jersey

      See all my reviews

      Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

      This unit does a nice job for basic compressor needs. It does however really lift the noise floor on highly compressed sounds. You will hear the gain loud when the gate kicks off. This will happen in most cases however other units with better specs will have a better signal to noise ratio than this unit (what do you expect at this price level?) I have not compared to the dbx units at this level however this unit has good features and works well for alot of applications so I consider it a good value for the price they are asking.If you need better signal to noise ratios spend more $$$$ on a better unit. Recommended.

      Great Compressor...

      from Nitro, West Virginia

      Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

      Great compressor, but the noise gate only works when there is no audio, just noise, if that makes sense. I mean, when your playing a song through it the noise gate does nothing until it is over, then it kicks in and cuts the signal. The compressor works very well electronic drummers. I have the Alesis SR-16 Drummer and it really put smack to the snare. Overall: Great product.

      Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

      Most home recording musicians need more compressor channels and who could beat adding two, independent or one stereo pair with a gate for this price? I think all Alesis home-end gear sounds very clean. It's very similar to the Behringer, but what makes it better? Easier to use gate (great for miking drums by the way). What would be nice? Built in transformer so I could use a power cord instead of a "wall wart". I'm buying another!

      Transparent Compression

      By Anonymous

      from Undisclosed

      Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

      This is a very nice compressor. I use it for recording vocals and distorted guitar, and find it to be very useful in both aspects. The gate is alright, though I dont use gates very much. But if used properly, it does it's job also. It's worth every penny, plus a few more, in my opinion.

        I already had three of these. They are are great little units. Very easy to use and with a little practice and finesse, you get a wonderful compression for very little money. They are great for bass and tight drums (speaker protection, too!). I also side chain mine with EQ and get really cool sustain on cymbals (overheads). I had noticed there are a lot of pros around using these little gems, too - now I know why. A lot of bang for the buck. The four of them give me 8 channels of compression inserts.

        Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

        Audio engineer, pro musician, installer for the last 15 years. Lots of knobs and switches is no substitute for sounds quality. This compressor sounds like garbage on bass, snare and kick. For only a little more you can get a DBX. So why waste your time with a rinky dink piece of junk. OTOH the old microlimiters are acutally kinda good.

        I purchased this because I needed a noise gate and a Compressor/Sustainer. It works out great! Of course it's a rack unit, it took A LOT OF TIME turning knobs to get it to that sweet spot, but now it does exactly what I needed it to do to! Beautiful piece of equipment, nice price.

        Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

        I bought mine used from a bulletin board. I'mvery happy with it. I've very successfully usedit on keyboard and bass tracks. It works exceptionally well in conjunction with my Presonus"Blue Tube" for recording vocal tracks. My onlycomplaint is that the front panel control knob designations are very hard to read in low light conditions. Although, that's not a problem once it's set.

        Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

        I believe you will not be sorry for purchasing this item but you always get what you pay for. This unit requires practice and patience but can perform.
        + Has everything one would want in the compression arena. Have seen the complaints about the noise gate, all I can say is be patient and work with it.
        + Manual is a great guide for starting out with the applications of comp/limiting.
        + Channel linking.... good.
        + Input pad..... good.
        + Price for performance.... very good.
        + Has held up on the road. Maybe not "tough" but certainly "durable".
        - Panel markings are hard to see without a close light and the light cannot be bright as it will wash out the panel. Do not understand the use of dark gray on black and the fix for this seems easy; use white or yellow.....very bad
        - Unbalanced I/O..... bad
        Well built, have traveled it in a 4u Rock Bag for a few years with preamp, eq, and effects and is good as new.
        Works well for the money, a worth while entry point. This unit will not ruin you to compressors and may inspire you to trade up when you can.

        Well I owned one for a few years. It looks like it would be a good compressor BUT it colors the sound a lot. I found it hard to even do light compression without the mix sounding boxy. The gate works pretty good. I owned two DBX over easy compressors I should have kept and currently use a RNC that sounds nice. But no gate.

        Comments about Alesis 3630 Dual-Channel Compressor/Limiter with Gate:

        My band is heavily electronic. I bought it to keep our singer in the mix and compress my 3 electronic signals. I tweaked it for about fifteen minutes and got a great compression ratio. That is where people loose faith in this thing. It DOES take tweaking, and you kinda have to read the manual to know what you are doing. When we stop playing, there is no white noise. I turned it off in mid song to hear the effect of the compressor, and its the difference between a "tin can" sound and excellent live sound. The quieter parts of our songs are just as robust as the louder chorus'. Yes, the more expensive units are better, but you cant beat it for beginning musicians. we record all our music using this as part of our live/recording rackmount.
