Sound Pure's Take

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!

Langevin ELOP

Set it and forget it! Our Langevin ELOP® Limiter makes your job easy. The principle of operation is based around using a rectified sample of the audio to shine an LED (Light Emitting Diode) onto an LDR (Light Dependent Resistor). The photo-resistor in combination with a fixed resistor simply act as a changing voltage divider to attenuate the signal-- like a smart volume control. A similar principle was found in the older Teletronix & Urei LA-2A, LA-3, and LA-4 units which used a slower electro-luminescent panel-light on a conventional LDR encased in a light-tight enclosure. Ours uses modern VACTROL technology (but with a trick!) for exact sample-to-sample tracking and no high frequency loss while digging deep into limiting-- problems commonly associated with older LA-series limiters and other opto-based units.

The audio signal passes only through all-discrete Class A amplifiers in the Langevin version. Each channel can be run separately or switched to "stereo - link". Due to their inherently quick attack, these Electro-Optical Limiters are skilled soldiers for tracking vocals or individual instruments.
