GML 9500
The 9500 Stereo Dynamic Gain Controller is a laboratory-level precision mastering tool. For serious professionals who demand the ultimate in transparency, the all-discrete 9500 delivers true reference-quality dynamic control. What else would you expect from the genius of George Massenburg?
The 9500 is the Mastering Version of the 8200. The Gain, Frequency, and Q controls are fully-detented for absolute precision and repeatability. With 1/2dB steps of Boost and Cut and 24 different frequency choices per band, the 9500 is a powerful and comprehensive workhorse for Mastering Engineers around the world. This dual-mono, 3U “King of All Equalizers” requires two 8355 power supplies.
Features:
- All-discrete dual-mono mastering equalizer
- 5-band stereo parametric equalizer with 1/2dB increments of boost or cut
- 24 selectable frequencies per band
- Fully detented controls for precision settings
- Compact design in 3U rackmount case
