George Massenburg Labs - GML 2020 « Direct-to-Tape » - Préamp / EQ / Comp Channel Strip

The 2020 is a brand new mono blockbuster combo 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 accurate LED input metering.
From -10dB of attenuation up to a whopping 70dB of amplification, Input Gain is selectable in precise 5dB steps accommodating all sources from low output ribbon mics through semi-pro keyboards to inserts in super hot mastering chains with one knob. Both the EQ and Dynamics sections are independently bypassable and up to eight 2020 units can be linked for multichannel work.

Especially useful about the 2020 is the way the 8200 EQ section can be placed either before or after the 8900 Dynamics section, or inserted into the Side Chain at the flick of a switch. This feature alone makes the 2020 an extremely flexible recording tool. A rugged 2U chassis houses all these fabulous features together.

The 2020 requires one 9015 external power supply.
