The ATC P4 Power Amp is a 5U rack-mounted 850W Class A/B monobloc power amplifier - only available as part of an ATC Active Loudspeaker System

With an ATC P4 you will have more than just the power and sound of the amplifier to produce top quality results. No matter that the power is huge and the sound of the amp is excellent and no matter whether you are in the studio or on the road, the P4 will deliver consistent results.

What you also have is the reputation that the Acoustic Transducer Company has built up over decades - firstly as one of the UKs premier speaker manufacturers, providing hard-working speaker drivers for the major artists of the day - so they know some things about what amps like the ATC P4 are driving - but also from their work developing active systems, crossovers and reference monitors.

A four-way system that delivers 850W of punch and precision, the ATC P4 monoblock has active crossovers and triple fan cooling to ensure that the amp stays cool even when the gig hots up - soft limit protection is included to make sure that your drivers are protected, no matter what you feed your P4 Power Amp By using the knowledge acquired over so many years, and adding their commitment to be the best by providing you with the best, ATC has manufactured the P4 Power Amp to give you the power to take on any situation.
