The GLA-OP1, Governor is a highly distinctive, dual-channel, tube optical compressor. We believe it can be considered one of the most progressive optical compressors. In its operation, it builds upon and elevates the concept of the Bishop’s dual slope optical compressor, taking it to the next level. Based on valves, it features a more parameterizable version of the Tube Boost function found in the Empress. In addition to the side-chain filter, it can receive an external side-chain signal and operate in both stereo and mono modes. It offers three compression modes, ranging from a gentle leveler style to an aggression what previously unheard of in optical compressors scene. It can handle timing automation and includes a meter section with a peak hold function, providing precise feedback on the compressor’s operating status.
