Classic feed-forward VCA compressor


In the realm of audio engineering, Dave Harrison, the founder of Harrison Audio, stands out as a pioneer in the development of music production technology. Ironically, Dave Harrison himself was initially skeptical about compressors, a sentiment shared by his friend and legendary music producer and engineer, Bruce Swedien. Both held the belief that music should be captured authentically, without interference. However, the requirement for a compressor arose from the broadcast market's demands, seeking a tool to control dynamics and prevent clipping. To meet this demand, Harrison Audio ventured into the realm of compressors, with the result proving extremely effective. Its transparent 'leveling' capabilities, achieved with just a few dBs of gain reduction, quickly made it indispensable in music production for delicately smoothing signals, particularly on vocals, guitars, and other instruments with wide dynamic range. Over time, this compressor's ability to 'dig in' became apparent, transforming it into a sought-after vibe compressor when higher levels of gain reduction were applied. Dave Harrison's initial skepticism gave birth to a tool that not only met the broadcast market’s demands but also became relied on in the world of music production. Thanks to the Comp module, the distinctive Harrison sound is now accessible in the 500 Series format.

Harrison's secret sauce – put it on everything

The Comp module is a very flexible dynamics processor. From a transparent ‘leveler’ on guitars and vocals, using a 1:2 ratio and fast release, applying 2-3 dB of gain reduction. To a sizzling vibe compressor on drums and bass, slamming the ratio in combination with a slow release. The Comp 500 Series module is a well-crafted, no-nonsense compressor that is your secret production ‘sauce’ – you’ll put it on everything.
