The re-engineered design of the C1 Mk2 incorporates ATC’s customarily transparent circuits boosted by larger power supplies, the latest ATC grounded-source 200 watt Class A/B discrete MOSFET power module and improved overload protection circuitry (with front-panel indicator) for greater control at full output. The low-pass filter circuits have been comprehensively re-worked to facilitate the best possible integration with partnering speakers from ATC and other manufacturers.

Controls include a continuously variable low pass filter, a continuously variable all-pass filter and polarity switch, speaker level L/R inputs, independent L/R RCA line inputs and a summed line output RCA connector to facilitate the daisy-chaining of multiple subwoofers.
