Notes: FINISHED product, current line. Marketed by Gyraf as 'world's first passive compressor with dual stereo/M-S function.' Photoresistor (CdS cell)-based passive gain reduction inspired by the G21. Manufacturer notes a regulatory caveat: due to CdS-cell (cadmium sulfide) composition, EU and California customers require a loan/exemption agreement — flagged as a notable compliance detail, not a spec. Available in 230V or 115V mains versions. No tubes in this unit (passive resistor/transformer/photoresistor path) despite Gyraf's tube-brand reputation — flagged. digital_control inferred 'false'. No USD price published. Rack height, frequency response, and year introduced not stated.
