The Chandler TG Opto compressor is a handmade, fully discrete, mono, dual space module, designed for the 500 Series format.The TG Opto for 500 Series is a relative of the TG1 Opto, found in Chandler Limited’s TG Microphone Cassette, the TG1 Limiter and Zener Limiter, and traces its lineage to the historic EMI TG12413 limiters found on the TG12345 mixing and mastering consoles of the late ‘60s and early ‘70s.


The TG Opto compressor control-set includes: selectable sharp and rounded knees, continuous input, output (makeup gain), attack, release, and true bypass.


The attitude of the TG Opto is one of two personalities, each actuated by the selectable sharp and rounded knee types. In sharp, the TG Opto is capable of explosive drum sounds, and set to rounded, it is well suited to scenarios where the artifact of compression is required to be less obvious or gentle.


The continuous control-set affords the ability to fine-tune compression to respond to an array of sources and create a variety of tones.
