GML Model 8200
Product Overview:

2 Channel, 5 band Parametric Equalizer

Overview

Brought to you from the man who invented the term “Parametric Equalization”, 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. The 2U 8200 uses one 8355 PSU.

The GML 8200 Parametric Equalizer is of a fifth generation progressive design, the result of ten years of creation, listening analysis, the most versatile and musical sounding circuit topology & fine tuned control parameters to satisfy the needs of the most demanding professional. Certainly the most carefully designed and constructed equalizer GML have produced, this new unit is hand built and calibrated in limited production quantities using selected components.
