Performance-focused Power for Pros and Audiophiles Alike
Offering exceptional performance for both studio engineers and hi-fi enthusiasts, the ATC P1 power amplifier houses grounded source-class AB output-stage circuits derived from the company's world-class active studio monitors. Rated at 150 watts per channel, its dual-mono configuration delivers full power simultaneously from both channels with minimal crosstalk. Exceptionally wide bandwidth, low distortion, and ample dynamic range translate to precise accuracy and flawless transient response. Meanwhile, its neutral fidelity ensures broad compatibility with partnering units, including bi-amp integration with ATC's larger P2 amplifier. The P1 includes both balanced and unbalanced inputs, as well as unbalanced Link outputs. Handbuilt in the UK, the ATC P1 offers an outstanding upgrade for passive loudspeaker systems.

The legacy of ATC monitors
A young engineer named Billy Woodman spent his formative years working side by side with some of the best speaker engineers of the day. In 1974, Woodman went on to found ATC (Acoustic Transducer Company). Since then, ATC has focused on one thing: creating the most accurate monitor loudspeakers possible. If you want to make great-sounding recordings that translate to the world outside your studio, accurate monitoring is a must. You need to hear every nuance of your audio, exactly as it was recorded and mixed. ATC monitoring equipment, expertly engineered with the highest-grade components, is designed to do provide just that. How good are ATC monitors? Just ask renowned producers and engineers like George Massenburg, Chuck Ainlay, Nathaniel Kunkel, and Doug Sax. You’ll also find ATC monitors in Abbey Road Studios, Sony Studios New York, Blackbird Studios Nashville, and many more world-class facilities. Sweetwater is proud to offer you ATC’s extensive range of professional studio monitors.
