Alesis 3630 - Dual Mono/Stereo Compressor/Limiter with Noise Gates

B&H # AL3630 Mfr # 3630 COMPRESSOR
No Longer Available

The 3630 Compressor provides two independent full-featured compressor/ limiters with noise gates in one rack space, and offers excellent sonic quality for any application, from studio recording to live sound or broadcast.

The 3630 has ratio, threshold, attack and decay controls to customize any kind of compression response, even for the toughest signals. The user can also choose between RMS and Peak compression styles, plus Hard and Soft Knee dynamic curves for every application, from subtle gain control to extreme punch.

Two fully independent gates with threshold and rate controls allow the user to easily and efficiently suppress unwanted ambient noise. The 3630 provides precise signal metering, sidechain access for keying or ducking effects, and stereo linkable operation.

Two channels of compression/limiting with gates
Stereo or dual mono operation
The unit can serve as two totally in-dependent units, or both sections can be strapped together for stereo operation
Peak or RMS response
"Hard knee" or "soft knee" response
Individual bypass switches for each channel
Side chain connections
Allows for insertion of EQs and other devices for de-essing, adding treble to darkened signal due to excessive limiting, "keying" one signal with another, ducking
Built-in stereo/dual mono noise gate

        Comments about Alesis 3630 - Dual Mono/Stereo Compressor/Limiter:

        The only reason I purchased this was to level out my cable TV's audio signal. i.e. The much louder commercial volumes than the television program volumes. Yes, it does kill the dynamics in movies, but thats what I need while the kids are going to sleep. It works well for my application and I have also used the 3630 in live sound, but I wouldn't use it for recording. Not bad for the price!

            Installed at the head end of a 525 room cable television system at county hospital. Placed after switcher and just before the modulator. I am getting good feedback that it is working well. We had large variations in sound levels from our 16 sources and this unit has made our sound come out at an steady level. I am running it 24 / 7. A great deal and very impressive for [$].

              I'm using this in conjunction with a Behringer sound mixer and this works very well to import audion into my Decklink Studio import card. It prevents a lot of problems before it gets into Adobe Premiere Pro cs5.

              The 3630 Compressor is just a simple hardware compressor, but it packs a punch when it comes to it's sound and ease of use. I am a beginner when it comes to using hardware in my studio, this compressor works well on vocals it keeps them even but yet dynamic in a mix.
