With astonishing precision and sonic accuracy, the GML 8200 Parametric Equalizer has been an industry standard for over two decades. Its operational characteristics have been honed through many years of use in the most critical recording and mixing situations and can be found on virtually every major recording studio’s stereo bus. Each of the five broadly-overlapping bands offers 15dB of Boost or Cut and adjustable bandwidth (or “Q”) from 0.4 to 4. The lowest and highest bands also can be switched to Shelf mode. Quite simply, the 8200 is the archetype Stereo Parametric Equalizer. Its extraordinary resolution, benchmark transparency, generous headroom, and surgical precision have been the reference for many other equalizers but exceeded by no other.
