The ATC P1 is a dual-mono power amplifier, hand-built in the UK, offering 150W per channel. It features a class A/B output stage, similar to those found in ATC's active loudspeakers, ensuring wide bandwidth and ultra-low distortion. The P1 is designed to complement ATC's range of hi-fi pre-amplifiers and is suitable for a wide range of passive loudspeakers. It includes balanced and unbalanced inputs, unbalanced 'link' outputs, and is gain-matched for bi-amp compatibility with the larger P2 model. The amplifier is backed by a 6-year warranty.
