George Massenburg Labs - GML 8200
The production of the different GML products was arrested by the manufacturer, no product will be manufactured at the moment and no info is not yet official about the future of the brand in the long term. Do not hesitate to contact us for more information and advice concerning the choice of replacement reference.
The 8200 has been an industry standard for over twenty 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. It fits into a 2U, 19" space and requires the external GML 8355 Power Supply.
