ATC P1 Pro Dual-Mono Power Amplifier
In Stock!

Reference-grade Monitor Amp

ATC designed their P1 Pro 2-channel monitor amplifier with a true dual-mono circuit topography. Engineered with completely separate power supplies and signal/return paths, the P1 Pro achieves maximum signal separation with minimum crosstalk. Intermodulation between the two channels via the power supplies is also reduced to absolute minimum at all frequencies, and power delivery from one channel does not affect available power from the other. What does this mean for you? Simply put, ATC's purist design approach ensures you of maximum monitoring accuracy - which will help you make better recordings. Packing 150 watts per channel, the P1 Pro is an ideal amp for driving passive monitors such as ATC's SCM12 Pro.

ATC P1 Pro Dual-mono Reference Amplifier at a Glance:
  • The benefits of speaker-optimized amplification
  • Monitoring accuracy with an audiophile sensibility
The benefits of speaker-optimized amplification

One of a handful of companies that pioneered (and ultimately popularized) active monitor technology, ATC have always engineered their own internal amplifiers. This makes them experts in the complex relationship between amplification and transducer - and what it takes for an amp to optimally drive a loudspeaker system. ATC's P1 Pro incorporates the same loudspeaker-protection and gain-reduction circuits the company uses in their active monitors, so even if you are monitoring at very high volume, clipping is avoided, protecting your speakers from damage.

Monitoring accuracy with an audiophile sensibility

Since 1974, 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 gear, expertly engineered with the highest-grade components, is designed to do just that. Sweetwater's advice: you can't go wrong with ATC - the studio monitor company trusted by George Massenburg, Chuck Ainlay, Nathaniel Kunkel, and many other world-renowned engineers.

ATC P1 Pro Dual-mono Reference Amplifier Features:
  • 2-channel monitor amplifier
  • 150W/channel into 8 ohms
  • Distortion: less than 0.002% (-95dB)
  • Loudspeaker-protection and gain-reduction circuitry
  • Front-panel standby button and rear-panel remote standby trigger input

Modern Convenience, quiet, clean and powerful

Coupled with the atc scm 12 passive monitors this is a great amp/combo. Love how I can power down quickly from the front panel of the unit for easy headphone monitoring. Well made. "Modern McIntosh" quieter and cleaner than my mac 240. I have always used passive monitoring so this was a natural upgrade from mcintosh and Adam anf-10 s monitor rig.
