No Compromise FET Compression for 500 Series The FC1 brings fully featured FET compression to the Drawmer 500 series range. With a complete control set and advanced shaping tools, it delivers the precision, flexibility, and character you'd expect from a full Drawmer rack-mount unit in a single 500 series slot. Based on the FET design of our 1970s range, the FC1 delivers soft-knee feedback compression with a fast, responsive character that's perfect for controlling transients, adding punch, attitude and aggression, and bringing sources forward in the mix. It excels on drums, electric guitars, and energetic vocals where impact, presence, and immediacy are essential. Total Control Uncommon in a 500 series compressor, the FC1 offers a comprehensive control set: 21-position precision detented controls for accurate, repeatable settings Input and Output gain, plus Threshold, Ratio, Attack and Release controls Wet/Dry mix control for parallel compression PGM mode introduces a second, slower release time that adapts to the programme material above the threshold, reducing pumping and unnatural artefacts during heavy compression Comprehensive metering with Gain Reduction, plus switchable Input or Output level on the VU meter Hard-wire bypass connects the input directly to the output for completely transparent bypass operation BIG and AIR Modes Borrowed from the award-winning Drawmer 1973 three-band compressor, the fully selectable BIG and AIR modes shape the compressor's frequency response, adding extra weight to the lows and enhanced clarity to the highs. BIG reduces the sidechain's sensitivity to low frequencies, allowing bass energy to pass through the compressor more naturally. This helps reduce unwanted ducking and pumping caused by dominant low frequencies, producing a more open and musical compression response. AIR preserves high-frequency detail that can often be lost during compression. The result is a more open, detailed, and transparent top end without harshness or artificial artefacts. Vocals become more articulate, acoustic instruments retain their natural detail, and cymbals remain vibrant without becoming splashy. CRUSH Saturation The FC1 also features Drawmer's popular CRUSH harmonic saturation circuit. Its effect varies with the input level, adding harmonic richness, subtle saturation, and the analogue warmth that helps mixes feel fuller and more engaging. The low end gains weight, the midrange becomes more present, and the top end retains a smooth, natural sparkle. Stereo / Group Linking Using the dedicated Link pin 6 on the 500 series chassis, adjacent FC1 modules can be linked together using the LINK button for stereo or multi-channel operation. The module applying the greatest amount of gain reduction becomes the master, ensuring all linked units track together accurately. Linking includes Gain Reduction together with the Threshold, Ratio, BIG and AIR functions for consistent stereo imaging and dynamic control.
