GML 2020


The GML one-box solution. The 2020 is a reference-quality combination of the legendary 8300 Mic Pre, a 4-band version of the 8200 Parametric EQ, and a complete 8900 Dynamic Range Controller. Additional enhancements not found in the stand-alone units include: Mic, Line, and Direct Instrument input selection, front panel mounted 2-Pole High Pass Filter, Phase Reverse, and Phantom Power switches, as well as fast and accurate LED input metering. Input Gain is adjustable from -10dB attenuation to 70dB of gain in precise 5dB steps. Each source is optimized at all gain settings for best noise performance. One knob optimizes low output ribbon mics to semi-pro keyboards to inserts in super hot mastering chains. Bypass controls are provided for EQ and dynamics independently, while up to eight 2020s may be linked for multi-channel work. A one-knob topology switch re-arranges the 2020 in such a way to enable the 8200 EQ section to be placed either before or after the 8900 Dynamics section, or conveniently inserted into the Side Chain. The 2020 is housed is a rugged 2U chassis houses and requires one GML9015 external power supply.
