Manley ELOP+ Stereo Electro-Optical Limiter


The original Electro-Optical compressor that now compresses and limits.  The updated 2016 version is really a do-all compressor that can be THE workhorse for your studio

What we think:

The ELOP is one of those processors that offers beauty in both sound and simplicity of design. With only two main controls (Make Up Gain and Gain Reduction), it’s pretty hard to mess this limiter up. Because of this and its relatively fast attack (for an electro-optical limiter), the ELOP is one of the best options I’ve used when tracking vocals, guitars, and bass. There, it serves as a smooth and responsive audio leveler by effortlessly controlling louder peaks, resulting in a more even and full performance with a touch of Manley’s famous tube polish.
Oh, and don’t let the “limiter” title scare you. While having a higher ratio that technically qualifies as limiting, the applications where you’d use ELOP overlap with where you’d use a traditional compressor, as opposed to solely mix buss or mastering purposes. Meticulous detail went into designing the ELOP to be a powerful yet forgiving and easy to use box - essentially it’d take some serious determination to make the ELOP sound bad! 
2016 Update!  Now we are talking compression or limiting!  With the new 3:1 and 10:1 switch, you can toggle between tracking a nice soft vocal for smooth compression to harder limiting on, say, drum overheads.  This really ups the versatility of an already incredible compressor. Working at 10:1 with the original ELOP was almost a limiter for many applications.  Sometimes it could be too much, and we wished for a softer compression ratio.  BAM!  The newer 3:1 setting is going to be dynamite for tracking when you need a touch of smooth and transparent compression, but it will still go hard with the 10:1 when you need that feature.
