Details

Controls: Compressor: Ratio (1.6:1-20:1), Threshold (Off to -20 dBU), variable Attack/Release with 6 Fairchild-style presets or manual mode, Output Gain (-6 to +10 dB); Limiter: Threshold (Off to 0 dBU), fixed Attack 0.8ms/Release 0.5s, separate on/off; clickless relay, LED GR display

I/O: Transformer-balanced, fully floating I/O; two 1/4" stereo jacks for link busses

Notable use: All-tube Fairchild-style vari-mu compressor with an additional dedicated tube limiter stage

Notes: Not opto - uses a tube-based VCA/vari-mu gain element (distinct topology from CL 1B/CL 2A/SMC 2B opto units); flagged per instructions for topology clarity. Price varies notably by dealer ($4,499 Thomann to ~$5,240 elsewhere); treat as approximate, not confirmed MSRP.
