GML 8200 Dual Channel 5-Band Parametric Equalizer

GML 8200 Dual Channel 5-Band Parametric Equalizer

GML 8200 Parametric Equalizer

Brought to you from the man who invented and coined the term “Parametric Equalization”, the 8200 has been an industry standard for almost forty years, 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. The 2U 8200 uses one 8355 PSU.
