The ELOP Stereo Electro-Optical Tube Limiter from Manley Labs is a two-channel leveling amplifier that produces instantaneous gain reduction with no increase in harmonic distortion. The limiter features an all-tube channel path, custom-wound transformers and dedicated high-pass filter. At the heart of the ELOP Limiter, lies an LED shining on to a light-dependent resistor (LDR). This photo resistor works with a fixed resistor to function as voltage divider to attenuate the signal based on the brightness of the LED, resulting in smooth, natural compression characteristics. Manley Labs have devised their own vactrol technology that tracks the audio with sample accuracy, but with no high-frequency loss; a problem often associated with other photo-optical limiters.
