ATC P1 Pro Dual-Mono Power Amplifier delivers 150W per channel @ 8 ohm/200W per channel @ 4 ohm with ultra high bandwidth, low distortion, and high dynamic range for tonal accuracy and perfectly timed transients

The ATC P1 Pro Dual-Mono Power Amplifier is very high-quality power amp hand-crafted to be the perfect partner for ATC’s high-performance passive monitors. The P1 Pro’s MOSFET Class A/B electronics are housed a boat-anchor solid, 19″ rackmount chassis with a front-panel standby button and L/R clip indicator. It can also be remotely put into standby via a rear-panel connector. The P1 Pro features the same gain reduction and speaker protection circuits found in ATC active monitors, which prevents clipping at high levels, thus protecting monitors from damage while providing an improvement in perceived performance. If you’re looking to provide your ATC SCM12 Pro or SCM20PSL MKII passive monitors with super high-quality, reliable power, the ATC P1 Pro is the answer.

ATC P1 Pro Dual-Mono Power Amplifier in one take:

  • True dual-mono design with isolated signal paths delivers full power from both channels with minimal crosstalk
  • Grounded source class A/B circuit topology found in ATC’s renowned active loudspeakers
  • Ultra-wide bandwidth, low distortion, and high dynamic range ensure tonal accuracy and perfectly timed transients
  • No compromise, high-performance power supply and large heat-sinks guarantee outstanding stability and long term reliability
  • A perfect match for any passive studio reference monitor
  • 19″ Rack mountable convection cooled chassis
  • Hand built in the UK with a 6-year warranty

 True dual-mono design

The ATC P1 Pro is a true dual-mono design, which means that the signal to the power supplies and return paths are completely separate. This design ensures maximum signal separation and minimum crosstalk, as well as reduced intermodulation distortion between channels is reduced to an absolute minimum at all frequencies. Also, the power delivered from one channel cannot affect the available power from the other channel.

The P1 Pro and P2 Pro amplifiers can be brought out of standby via the front-panel mounted button. While they are not equipped with an IR remote control, they do feature remote standby via a rear-panel 5 – 12V AC/DC input.

Hand-crafted for a lifetime of reliable service the P1 Pro is the perfect companion for ATC passive monitors. For more information, call or chat online with your Westlake Pro sales consultant today.
