The BC1-THD is a smooth bus compressor ideal for mixing and tracking. Engineers often describe the BC1-THD's compression as "magic glue," enhancing mixes without sacrificing clarity. The built-in Mix control allows for easy parallel compression by adjusting the blend of the compressed wet signal and the original dry signal. An on/off sidechain filter prevents the compressor from responding to signals below 150Hz, allowing you to tailor the compression response to input material with a high level of low frequency content. External sidechain support is also available. The newly added THD function adds harmonics to the signal, and "Grab" mode provides a harder threshold knee at all ratio settings. These features combine to create the BC1-THD's smooth, clear, yet modern compression. TK Audio BC1-THD Features: The BC1-THD is a smooth bus compressor ideal for mixing and tracking. Engineers often describe the BC1-THD's compression as "magic glue," enhancing mixes without sacrificing clarity. The built-in Mix control allows for easy parallel compression by adjusting the blend of the compressed wet signal and the original dry signal. An on/off sidechain filter prevents the compression from responding to signals below 150 Hz, allowing for adjustments to the compression response with low-frequency-rich input material. External sidechain support is also available. The newly added THD function adds harmonics to the signal, and Grab mode provides a harder threshold knee at all ratio settings.
